Choosing the Powersource 1800 Solar Generator for the Home

Everyone has been preparing more than usual in the past 2-4 years since they are constantly being told about how disasters can strike at any moment and how EMP attacks could occur, even the Bible talks about times when nations will go to war against nations. With all of this kind of information, it only makes sense to get right with God and start preparing, even Noah prepared. The solar generator we are focusing on today is the Powersource 1800 Solar Generator, we will list some features, our recommendation and the run times for some appliances. There are some bigger unit generators available but due to the fact that we are trying to focus our products towards the majority of consumers, we are discussing the most affordable solar powered generators.

The solar powered generator that consumers have been purchasing for over 3 years is the Powersource 1800 Solar Generator. As you can probably tell, the 1800 stands for 1800 watts of power and its solar powered. This generator is able to power your electronics with the 1800 watt battery bank and can be charged either by the included 90 watt solar panel or the included wall adapter. The way it works is truly as simple as plug in play because once you receive this, you take it out of the box, plug in the cable to the generator and the other to the panel and you are good to go and have power. The run times for this unit all depends on what is being powered, but here are the most common devices and their run time. A cell phone is 63 hours at 5 watts, what this means is you could use your cell phone for 63 hours if you needed to before you would have to charge the generator again. A laptop would be about 22 hours at 20 watts, a lamp would be 10.5 hours at 40 watts, a sump pump ½ HP would be able to run for 1 hour at 300 watts, and a microwave for 12 min if its at 920 watts. These are just some of the devices people use when they are using the Powersource 1800, you can always get more creative and think about other appliances like hot plates, coffee makers and toasters.

This unit is mostly geared towards families and couples who demand a higher standard of living. The cost is around 1697.99 and is well worth the money if you have no clue how to deal with terminal wires, solar panel installations, amp configurations, electrical box and charge controllers because the Powersource 1800 Generator provides you with everything you need to just plug and play. This is a huge time saver for parents because they need the assurance of something they can rely on when they have kids running around scared when disasters do happen and nothing is worse than having a unit not working because the wires are not properly installed and the charge controller not correctly optimized.

Some of the features that are included in the Powersource 1800 is the four 115 vac power outlets, to keep this simple, we are talking about 4 outlets like the ones you see in your home today. This is an excellent feature if you have many devices you want to charge at the same time, like your smartphone, laptop, or if you want to cook with your hot plate while brewing coffee at the same time and even breast feeding with a pump for those who have infants.

Also, the bright LED light turns on automatically when the power outage occurs to provide illumination over the AC outlets. This is very helpful during complete blackouts so you can find where to plug in your lamp. There is also a an audible alarm that signals 10 minutes before the unit runs out of battery power. Another useful benefit when you don't remember how much power you have used, perfect for parents to stay alerted and plan accordingly. Another key feature is that you don't have to use this only for emergencies you can also use it for outdoor professional activities, like power for outdoor photography, camping and for those secret cabin getaways you own.

The Powersource 1800 Solar Generator is the original solar generator that was built for and meant for emergencies, backup power and small to large families needing a reliable power source during disasters. If you have thought about this unit before, remember thousands of customers have purchased this and thousands are still purchasing this because of the quality and craftsmanship. This unit is built in the United States and shipped in the USA and other countries where customers truly need a backup solar power solution.

The Costs of Residential Solar Energy Systems

Installing a residential solar energy system is a great way to offset the cost of your power bills. Increasingly, utility companies are introducing time-varying rates in an effort to better reflect the actual costs of producing electricity. This means that you can offset most of your electricity costs by installing a PV solar array.

Costs of a residential solar energy system

There are many factors that determine the costs of installing a residential solar energy system. These include a homeowner's solar panel installation costs, the inverter used to convert direct current to alternating current, metering equipment, and various housing components and cables and wiring gear. Some homeowners also opt to store excess power in batteries to use later. This can be a viable option, but historically the costs were prohibitive. Also, solar panel installation costs must be factored in, which includes installation costs and labor.

The average cost of a residential solar energy system varies greatly depending on region and wattage. In the southern United States, the cost of solar installation can be as low as $2.50 per watt, while in New England, the cost can be up to $3 per watt. These costs are for equipment, installation permits, labor, monitoring, and operational costs.

Cost of a grid-tied system

The most common form of residential solar energy system is a grid-tied system. This type of system connects your home's solar panels to the grid, which is typically your local utility company. This system has several advantages over an off-grid system. For one, it does not require a battery, which can be costly. Plus, it requires much less equipment, including solar panels and other related parts. Moreover, it requires less labor from solar installers, which results in lower costs.

One downside of a grid-tied system is its limited battery storage. Most grid-tied systems do not have enough battery capacity to supply backup power to a whole house in case of a grid outage. That's why it is important to identify your critical loads, such as a refrigerator, modem, and a few lights or outlets. Then, you can determine whether or not the system you choose is sufficient.

Cost of an off-grid system

Cost of an off-grid residential solar power system varies depending on the size of the system. A small system is often comprised of one or two solar panels and a solar charge controller. A good quality small 20-amp solar charge controller will cost around $120. Other small systems typically incorporate a 12V or 24V battery inverter to supply basic AC power. These are also available in many different sizes.

During the early stages of a residential solar system project, it's important to determine how large the system will be. This will determine the equipment needed, installation cost, and the final cost of the project. In general, a solar setup size will be based on how much energy a household will need to operate daily. A good way to estimate this is by looking at the monthly power bill. This can then be converted into kilowatt-hours.

Cost of a ground-mounted system

The cost of a ground-mounted residential solar energy installation will depend on a number of factors. For instance, the type of mounting system chosen for your ground-mounted solar energy system is one of the biggest determinants of the overall cost. Ground-mounted systems tend to be cheaper than rooftop systems, as they don't require poles. However, they often require additional supports in the ground, which may increase the labor and component costs.

Another factor that contributes to the cost of a ground-mounted residential solar energy systems is the cost of the land. Rooftop systems require space that is not always accessible, and ground-mounted systems need valuable land. This land is also more susceptible to damage from people and wildlife.

Cost of a buyback agreement

A buyback agreement helps homeowners reduce their monthly electricity bill by offsetting the cost of power from their utility company. The avoided cost of solar power is typically about half the rate of power generated by the homeowner's solar energy system. It can be tricky to calculate the avoided cost, but it's an important consideration if you want the most cost-effective solar energy system for your home.

With this type of agreement, the homeowner pays a fixed monthly rate for the life of the PPA. In addition, the homeowner may choose an escalator plan that increases their monthly bill by two to five percent each year, but is less costly than an increase in utility prices. Another option is a fixed price plan, which maintains a constant price for the life of the PPA. This option will save homeowners more money as utility prices rise. A buyback agreement is not a government program, but there are consumer protections and consumer benefits.

Let The Solar Free

Anyone tackling solar power for the first time will quickly find there’s a truly dizzying amount of information to understand and digest. You might think you just need to buy some solar panels, wire them together, and just sort of plug them in. But there are a hundred and one different questions about how they’ll be connected, the voltage of the panels, and the hardware for driving a load. [Michel], [case06], and [Martin Jäger] have set out to create a simpler and easier to understand charge controller named LibreSolar.

A charge controller is fundamentally a simple idea. The goal is to charge a battery with solar panels, which means it’s essentially just a heavy-duty DC/DC buck converter. What makes this project different is that it is an open platform built for extensibility.

There are UEXT connectors included for adding extra peripherals, and with some tweaks to the STM32 firmware, it would be easy to handle small wind turbines (with some rectification to convert to DC, of course). LibreSolar seems to be designed with an eye towards creating a nano-scale localized networked grid. For example, they’ve developed a Raspberry Pi Zero module that uses WiFi to create a CAN bus allowing the boxes to communicate their maximum voltage to each other. This makes the system as plug-and-play as possible, as the bus doesn’t require a master controller to communicate.

With features such as MPPT (Maximum Power Point Tracking), 20 amp peak charging, a USB interface for updating, and several built-in protection mechanisms, it’s clearly a well thought through project. We look forward to seeing it deployed in the real world!

Portable power station 500w

Wow! I own 6 other Power Stations and finally found one that has all the features I'm looking for. 1. This BULLBAT has a built-in MPPT charging section. Why is this important? You can directly connect 12-30v solar panels to this and you don't need your own MPPT controller as it's built-in. MPPT or Maximum Power Point Tracking allows sources with variable power to maximize energy extraction from your solar panels. This is crucial for solar panels without it you can lose up to 30% of the panel's maximum wattage output. 2. It allows triple power inputs with pass-through charging while supplying AC and DC. This is crucial if you want to maximize the total kWhs you can get out of the unit per day. Without pass-through charging, AC would be off when recharging the batteries. So that would mean no AC for 6-10 hours a day! Also, You can turn this 500Wh unit into a 2000-3000Wh unit if you have some 12-24V lead acid batteries laying around. Just don't expect much more than it's rated 500 Watts.

I tested it to 800 Watts before it shut down but it held 600 Watts perfectly. How do you add capacity? Let's say you have a couple of cheap 12V 110Ah Group 27 lead acid Sealed cells laying around in your garage. You can connect them to this unit via the 12V-30V input and now you have 500Wh + about 1kWh x2 for 2.5kWh's of total energy all while the AC and DC outputs are on. The max charging input for me hit 229 Watts so that's the limitation on keeping the unit charged. I tested the 5V USB 3.0 and they will do continuous 3 Amps at 5.16 Volts (over 18 Watts) with zero sagging! This is great for the fastest cell phone charging! See image. The USB-C ports can both output 60 Watts Each and will Charge Apple Macbook Pros. The auto-detect voltages can adjust from 5 to 20 Volts. See the image The USB-C ports are directional so you can use your USB-C MacBook Chargers to boost Charging speeds. I managed a 110W (charger that comes with the UNIT + 60W + 60W for a 229 Watts Total of charging while simultaneously out-putting 400-500 Watts AC. See image. The Inverter is a True Sine Wave Inverter so it can safely power electric Blankets, laptops, CPAP, and Bi-PAP machines. I tested them all with it. The voltage for me held steady at 114 to 114.5 volts at 1 watt to 500+ with no spikes or peaks at all from no load to full load. See image. Overall Efficiency from the Battery including inverter DC to AC conversion losses seems to be right at 90%. This is very good. 12V DC output with no load is 13.3 Volts (Cigarette lighter style plug) I didn't have time to test the voltage at a full 10 Amps. The output on the 12 volt DC 2.2mm output Jack is also 13.3 volts The Unit has an LED light with low, High, Slow Strobe, and High Strobe. That draws the 2 and 4 watts low/high and it's very bright. I didn't use my photometric integrating sphere but the LED looks to be about 150 Lumens per watt on high. So expect a true 600 lumens output. It's right at 5,600 Kelvin with a great reflector and a low-loss lens and no hot spots. The onboard power management is great with real-time wattage input and outputs showing wattage Draw on AC/DC, Charging Watts, time left before the battery is depleted and time it will take for a full charge. The construction is solid and it's a hefty 12 pounds. It comes with a Solar charging adapter (MC4 to DC5525 cable) Just make sure your solar panels' Open Circuit Voltage (OCV) is between 12V-30V and does not exceed 30 volts. Since it has a built-in MPPT controller you can plug your solar panels indirectly. You can connect a few panels in parallel for faster charging just as long as you don't exceed 30 volts.

Max input via solar only is about 160Watts. If you have 200-400 Watts watts worth of solar panels you won't hurt anything as this unit limits the maximum charge rate. I hooked up 400 Watts of Sunpower flexible panels with no problems. They are Maxeon Sunpower flexible monocrystalline solar cells. 32 cells per panel, 4 panels all in parallel. Even if you only have a 10 Watt panel it will work it will just take much longer to charge. My panels are 17.5 Volts under load and a 21V open circuit. I was able to peak at a continuous charge rate of 229 Watts when using the Solar input and the USB-C inputs simultaneously. 160W with the Panels only. That's the fastest you can charge and is very fast for a 500wH battery as faster charging would just reduce the (total) charge cycles It also comes with a 12V auto plug adaptor so you can charge the unit while driving or from your car battery. The Unit is 100% silent on charging at 60 Watts and using AC at low Wattages. Somewhere in the 60W to 100W range the fan will kick on for both charging and discharging but it's very quiet.

The negatives that I found so far: I was able to trick the computer into thinking it had 9.9 hours of power left when connecting 3 charging inputs for 229 watts of charging input and simultaneously drawing over 400 Watts output. Not a big deal at all as it was the only info

[energy-unlimited]

My neighbor saw a couple of my demonstrations and asked me to build him an electric generator.

This is a combination of a vertical 120 winding pigtail bifilar coil and a two wire, 2 fold resonator using wire rated for 50 amps at 12 volts. It's calculated output is 20 times greater than it's input at 12 volts DC to a maximum of 600 watts.

He has an old 12 volt marine battery that hasn't been charged in over a year and reads 10.6 volts and a solar charge controller / inverter at another residence. Perfect... 🙂

Assuming his charge controller actually has a variable input / fixed output coil, unlike the junk I bought online, this nearly dead battery will self charge providing a bit more than 500 watts for the inverter.

After running this for a while and solving any issues that might arise, the next step will be to aquire a 110 volt variable input / fixed output coil and a non step 60 hz sinewave, 100 amp AC inverter.

Provides uninterrupted mains power

Off-grid solar panel charge controller. The solar panel charge controller is mainly used in off-grid solar power generation systems and is generally installed indoors. Main applications: solar battery charging, DC load output, liquid crystal display, manual switch. Mainly used for power supply systems such as home power generation, outposts, base stations, etc. In general, the price difference of small amps is not as large as that of large amps. The price difference between the MPPT controller and the PWM controller jumps after 30 amps.

MPPT charge controllers, ranging in price from $70 to $1000, are common in the market. Typically, low KVA inverter range in capacity from 600VA to 1500VA, while high capacity inverters range from 2KVA to 12.5KVA. To understand your VA output, you can divide the average operating load by the power factor. The efficiency of an inverter operating at 0.8pf is the power factor. Here is an example to give you a better understanding of the advantages of mppt, let's say you have a 1000W panel system, if you replace the PWM controller with an MPPT type, you only need to install a 700W solar panel to get the same power.

The price of solar panels on the market is about $2/W, then the overall cost of solar panels can be reduced to $650. In this case, in a larger system, the cost savings will be higher, including the cost of buying panels, cables, etc. When sunlight fades, the constant charge becomes the Solar Charge Controller. Through this switching method, the battery will be fully charged, the voltage will rise to the saturation voltage (Ur), and the battery will enter the constant charging stage.

Since the charging mode automatically switches between MPPT charging and constant charging, the solar energy can be fully utilized to charge the battery quickly and efficiently. In addition to these benefits, using an innovative PWM solar charge controller on older technology means reducing solar system cost and battery handling issues. It also improves solar system reliability and reduces load disconnects. It also provides an opportunity to reduce battery size to reduce system cost. PWM solar controllers are typically used in small 12V or 24V photovoltaic systems.

MPPT type regulators can also be used with 12v, 24v systems, but some models can also handle 36v and 48v systems if needed. Use this tool to easily determine the proper amperage for your controller. Inverters are overlooked because they are placed in corners, but it always does its job by providing utilities to make your life more comfortable and convenient. Upgrade your inverter, forget about all power outages and make a huge difference in your daily life. 1. Off grid solar panel charge controller.

Solar panel charge controllers are mainly used in off-grid solar power generation systems and are generally installed indoors. Main applications: solar battery charging, DC load output, liquid crystal display, manual switch. Mainly used for power supply systems such as home power generation, outposts, base stations, etc. UPS Mode - When the inverter is in UPS mode, the inverter voltage operating range is between 180V-250V. That is, the inverter will charge the battery within the above voltage range.

However, when the voltage is below 180 V or above 250 V, the UPS inverter cuts off the utility power and switches to the battery. This ensures the safety of sensitive electronic devices such as computers, hair dryers, blenders, washing machines, TVs, etc. If you want more power on the go for less money, this is the one for you. It will help you get 20% to 30% of the energy from the solar panel for charging. Stop wasting your solar system's energy when using a PWM solar charge controller to make the battery charge change by only 50%.

If you use lights, fans and any other electrical equipment with low voltage, it will reduce the performance and life of the equipment. Our mains voltage regulators are designed to protect your entire home from constant low voltage power and provide uninterrupted mains power.

Good circuit protection functions, including photovoltaic reverse polarity protection, photovoltaic overcurrent protection, battery reverse polarity protection, battery overvoltage protection, battery overdischarge protection, load overcurrent protection, load short circuit protection, etc. The working principle of the MPPT charge controller: The MPPT charge controller tracks the maximum power point of the solar panel in real time, and the solar panel outputs the maximum efficiency. The higher the voltage, the more power can be output through MPPT, which improves charging efficiency.
