#Residential Energy Storage Systems

[aeautoevcharger]

Background of the Rise of Residential Energy Storage Systems

The world attaches great importance to renewable energy and smart grids. With the promotion of initiatives such as the “Million Solar Roofs Plan” in the United States and the “Energy Transition” in Germany, the government provides high subsidies for the private use of photovoltaic power. As a result, households can achieve self - sufficiency in electricity and store surplus electricity, which is particularly prominent in the residential energy storage market in Germany and Europe. In today's era of rapid development of intelligence and information, the global electricity demand is growing explosively, bringing energy supply, pollution and consumption problems. Photovoltaic power generation is favored around the world. Thanks to policy support and the reduction of power generation costs of photovoltaic energy storage technology, residential photovoltaic power generation and energy storage systems have entered thousands of households. It can not only help households achieve self - sufficiency in electricity and reduce dependence on traditional power grids, but also store electricity for emergencies during peak periods of low power consumption.

Basic Structure and Working Mode of Residential Energy Storage System

Grid - connected Residential Energy Storage System Components: Solar cell array (the core, which converts solar energy into direct current, considering conversion efficiency, etc.), grid - connected inverter (converts direct current into alternating current, is compatible with household electrical equipment, and monitors and manages the operating status of the system), BMS management system (monitors the status of the battery pack and balances charge and discharge), battery pack (stores electrical energy, and its capacity, etc. affect energy storage capacity and service life. Commonly used batteries include lead - acid batteries, lithium - ion batteries, etc.), AC load (household electrical appliances). Working Modes: Mode 1: Photovoltaic provides energy storage and surplus electricity to the grid; Mode 2: Photovoltaic provides energy storage and electricity for some users; Mode 3: Photovoltaic only provides partial energy storage and does not transmit power to the public grid.

Off - grid Residential Energy Storage System Main Components: Solar array, photovoltaic inverter (has more functions in an off - grid system), BMS management system, battery bank, AC load. Working Modes: Mode 1 (sunny days): Photovoltaic provides energy storage and user electricity; Mode 2 (cloudy days): Photovoltaic and energy storage batteries provide users with electricity; Mode 3 (evening and rainy days): The energy storage battery provides users with electricity. Off - grid systems are suitable for areas where the grid is unstable or unavailable, and have higher requirements for battery bank capacity and management systems.

The Role of Battery Management System (BMS) in Residential Energy Storage Systems

The BMS is the “brain” and is of crucial importance. Main Functions: Data collection and monitoring (collect key parameters and current through real - time communication between the BCU and BMU modules), state estimation (calculate the state of charge of the battery and the remaining battery power based on the collected data), user interaction (display the real - time battery status, etc. through user interfaces such as touch screens). System Intelligent Management: Intelligent interaction (the BCU intelligently interacts with other system components through an independent CAN bus), safety control (the BMS implements secondary protection of charge and discharge through relays. When abnormal, the power is cut off to ensure the isolation of strong and weak electricity).

The Core of the Power Solution of the BMS of the Energy Storage System: Isolation Voltage Conversion

The key to the power solution design of the BMS is safe and efficient isolation voltage conversion. When the main control unit is based on a 24VDC system and the power requirement is less than 5W, a suitable power supply product can be used. For example, a power supply product can output 5VDC voltage to power the isolation module and low - dropout linear regulator (LDO). The LDO converts the 5VDC voltage to 3.3V to power the microcontroller (MCU). Multiple isolation modules in the system provide power for the CAN communication module, voltage and insulation detection circuit, and current detection circuit, and isolate the power circuit from the signal circuit and communication module to reduce electromagnetic interference and improve stability. Automotive - grade power supplies are widely used in vehicle BMS systems for vehicle battery management due to their excellent performance and stability.

In short, the residential energy storage system is an important link between the home and new energy. Its structure, working mode, battery management and power solution play a key role in the efficient utilization, stable supply and sustainable development of home energy. With the continuous advancement of technology and the promotion of applications, the residential energy storage system is expected to play a greater value in the future energy field.

Russia’s renewed and much broader assault on Ukraine’s energy sector this spring, which has now destroyed roughly half of the country’s electricity generation capacity, represents an explosive blow to Kyiv’s resilience, civilian morale, and industrial production. What’s worse, the ongoing Russian attacks on the vulnerable energy system offer few prospects of a quick fix that could right the situation before Ukraine enters its third winter of the war.

Since early this year, Russia has set out to finish the job it failed to complete in early 2023—the destruction of Ukraine’s civilian energy sector, especially the power plants that provide light and heat for millions of Ukrainians.

Beginning in March, Russia has specifically targeted Ukraine’s biggest power plants in six massive waves of missile and drone strikes, wiping out about 9 gigawatts of electricity generation, or half the country’s total. Ukrainian President Volodymyr Zelensky told a reconstruction conference in Berlin on Tuesday that Russian strikes have wiped out 80 percent of Ukraine’s big coal- and gas-fired power plants and one-third of its hydroelectric facilities.

Especially as a result of the last two big attacks, in early May and early June, Ukraine has had to ration electricity for industrial and residential consumers, leaving many with power for only short periods of time; some cities, such as Kharkiv, on the country’s eastern front line are virtually powerless. Russia’s assaults, which the U.K. ambassador to the United Nations has argued are in part an attempt to terrorize civilians, are even a subject for the U.N. Security Council.

As bad as Russia’s attacks have been so far, they could get worse. Russia has already hit some of Ukraine’s natural gas storage facilities—underground bunkers that are used to store fuel both for domestic needs and to backstop European consumption. Further Russian strikes there could expand the pain of energy attacks beyond Ukraine’s borders, right at a time when Europe is scrambling to find a solution for gas transit flows across Ukraine into landlocked Eastern European countries, especially Austria. 

The other big worry is that Russia, after having already destroyed Ukraine’s main sources of baseload power generation, will finally knock its remaining three nuclear power plants off the grid. (Russia has since the early days of the war occupied Ukraine’s Zaporizhzhia nuclear power station, using it as a shield for its occupation of south-central Ukraine, but the station—Europe’s largest nuclear facility—is in shutdown and not generating power.)

“It sounds mad to attack the nuclear power stations, but Russia could hit the transformers near the nuclear plants. If they did this, the power system will lose its unity, and the country will be split into different energy islands, some with spotty power and some entirely without,” said Andrian Prokip, an energy expert at the Wilson Center’s Kennan Institute in Kyiv.

The undeniable success of this year’s Russian assault is a sharp contrast to its ultimately failed bid in the first winter of the war to freeze Ukraine into submission. Russia has thrown more ordnance at more vulnerable targets this time around, leading to longer-lasting damage that will be far costlier to repair. Only after the big strikes in early May did Ukraine have to start rationing power to residential and industrial consumers. There is concern among big industry, such as the country’s once-vaunted steel and iron industry, that the power outages could kneecap what appeared to be a miraculous wartime recovery of industrial output.

“The difference is that before they mainly targeted transmission lines and substations and now they are destroying power generation plants,” said Slawomir Matuszak, a Ukraine specialist at the Centre for Eastern Studies in Warsaw. “The previous attacks were relatively easy to recover from—a question of days or weeks. But you’re looking at one to two years now for a real rebuild, if that even makes sense, because they can simply be attacked again.”

For Ukraine’s leaders, the renewed Russian strikes pose a threat to the country’s already strained ability to sustain years of unremitting bombing assaults, social and economic disruption, and the increased mobilization of service members. The new campaign has redoubled Ukraine’s desperation to bolster its air defenses in order to protect what’s left of its energy system. 

“Russia’s goal hasn’t changed—they seek to destroy our energy system and use it as a weapon against our citizens,” said Kira Rudik, a Ukrainian parliamentarian who leads the pro-European party Holos and who described the constant disruptions to daily life from the power outages that come atop Russia’s ceaseless use of stand-off weapons to batter civilian residences across the country, including her own. (Zelensky said Tuesday that Russia had launched 135 glide bombs in just the last day.)

“So we are saying, get us the F-16s, get us the Mirages, get us to this luxury point where we can go to bed and know that we will wake up in the morning,” Rudik said, referring to U.S.- and French-made fighter jets. “In Ukraine, we do not have this luxury.”

The increased pace of Russian attacks on Ukraine’s infrastructure has also injected fresh urgency into the question of how and when to leverage Moscow’s frozen assets for Ukraine’s assistance. U.S. and European leaders are working on a plan to turn the proceeds of frozen Russian cash into a large loan for Ukraine. For those on the receiving end of Russian attacks, even discussions such as those at the reconstruction conference in Berlin seem too focused on rebuilding Ukraine after the war, rather than reinforcing Ukrainians’ will to resist now.

“We need the money now,” Rudik said. “We have a simple task before us: to survive the summer and get through the winter somehow.”

Some Western countries are heeding Ukraine’s pleas for more air defense, which could help protect both cities and critical infrastructure from Russian attacks, especially after the devastation unleashed in the May and June strikes. Germany is now mulling the dispatch of a fourth Patriot air defense battery, with Chancellor Olaf Scholz urging allies to do more; Italy is preparing to send more air defense systems of its own, while even recalcitrant countries such as Spain are sending more air defense ammunition. Late last week, the Biden administration included more air defense missiles in its latest aid package for Ukraine.

Getting more air defense is a necessary but hardly sufficient condition to begin rebuilding Ukraine’s battered electricity sector. Even at big plants that had an air defense umbrella, such as Kyiv’s critical Trypilla generating station, Ukrainian forces simply ran out of ammo under Russia’s big assault in April; the plant was demolished. But even with better air defenses, energy experts doubt more than 2 to 3 gigawatts of power generation capacity could be rebuilt before winter. That would still leave a big shortfall in power generation, not to mention the ongoing damage to combined heat-and-power plants that provide central heating during Ukraine’s brutal winters.

One short-term, but expensive, fix would be to rely on more electricity imports from Europe. Just before this year’s Russian assault began, Ukraine was actually exporting excess electricity production to Europe—but that was soon reversed. Today, Ukraine can import about 1.7 gigawatts of electricity from Europe and in a pinch can even get more than 2 gigawatts of power. The problem is that imported electricity is more expensive than the subsidized power Ukraine generated at home, exacerbating the country’s already strained finances. 

The other solution, long broached in Ukraine, is to build more small, decentralized power plants, including small gas-fired turbines and renewable sources such as solar and wind power. The push for more renewables has actually increased during the war, and especially in the wake of this spring’s Russian onslaught, as Ukraine seeks new sources of power generation. 

On Tuesday, members of the G-7+ Energy Coordination Group and Ukraine’s government outlined plans to make the electricity sector more resilient, including through more distributed generation. European Commission President Ursula von der Leyen said Tuesday at the Berlin conference that Brussels is raising money for urgent power sector repairs as well as a host of small-scale generators. “The aim is to help decentralize the power system and thus increase resilience,” she said.

The biggest advantage of replacing hulking, centralized power plants with a lot of smaller, widely scattered sources of power is that they are a lot harder to blow up with scarce Russian missiles.

“If you have sources of microgeneration, and lots of them, then Russia will not have enough missiles to hit all of them, even if they knew where they were,” Prokip said. “So distributed generation is the right way to go, but the government didn’t take enough steps to do this when it could.”

Biden’s ironically named Inflation Reduction Act (IRA) was supposed to create millions of green jobs and launch the “sustainable power” industry.

Subsidies flowed to support electric vehicles, wind farms, and solar energy.  We have been covering the slowdown in the EV market, and residents of the East Coast are questioning all the promises made by the wind energy companies after the Vineyard Wind blade failure.

Now, it’s time to turn our attention to solar power. SunPower, the company that provides solar panels to many Californian homes in the sunny Coachella Valley area, filed for bankruptcy this week.

It is the latest development in a saga that has seen the company facing numerous serious and seemingly escalating challenges over the past several months, including allegations about executives’ misconduct related to the company’s financial statements and a recent decision that SunPower would no longer offer new solar leases. Days after the latter announcement, Coachella Valley-based Renova Energy, which markets and installs SunPower systems, said it was ending its partnership with SunPower and temporarily pausing operations after not receiving required payments from SunPower. SunPower’s executive chairman wrote in a letter posted on the company’s website on Monday that the company had reached an agreement to sell certain divisions of its business and suggested it was looking for one or more buyers to take on the rest, including the company’s responsibilities to maintain solar systems it has previously sold or leased.

It is important to note that SunPower was the industry’s “darling” to understand the magnitude of this development.

Founded in 1985 by a Stanford professor, SunPower was, for the past two decades, a darling of the solar industry. The company helped build America’s biggest solar plant, called Solar Star and located near Rosamond, California, and has installed solar panels on more than 100,000 homes. The company’s stock price has fluctuated dramatically, peaking during the solar stock frenzy of late 2007. As recently as January 2021, SunPower’s valuation momentarily reached $10 billion, buoyed by the expansion of its residential solar panels program. But since then, the company’s value has cratered — and this year, its situation became particularly dire.

It is also important to note that earlier this month, the bankruptcy of a solar-powered company in South Florida created an array of problems on the South Coast of California. Subcontractors are scrambling to find ways to guarantee payment for work on homes with equipment from the firm.

Meanwhile, homeowners are regretting their misplaced trust in eco-activists and city officials.

The business — Electriq Power Inc. — was putting solar panels and batteries on Santa Barbara rooftops at no expense to homeowners and with the blessings of the cities of Santa Barbara, Goleta, and Carpinteria. But then Electriq filed Chapter 7 on May 3, freezing all its operations. This prompted one of its subcontractors, Axiom 360 of Grover Beach, to place mechanics liens on homes for which it had yet to be paid. This preserves Axiom’s options for full payment of its installation work and is not unusual among contractors. But for homeowners who didn’t expect any financial outlay, it came as a shock, especially as the recording notice lists foreclosure in 90 days among the penalties. “You’re helping the environment. You’re not paying high rates to Southern California Edison,” said homeowner Randy Freed, explaining why he signed on to Electriq’s PoweredUp Goleta program. He was pleased with the savings in the solar array and storage batteries, but then he received the mechanics lien in June. The possibility of foreclosure was unanticipated, Freed said, and he’d relied on the cities’ endorsements. “It’s a great program; we’ve checked them out,” he recalled the cities saying on a postcard he received.

Hot Air's Beege Welborne takes an in-depth look at the cascade of warnings that indicate SunPower and the residential solar market are in serious trouble. She also hits on a point that is true for all green energy schemes: Today’s technology cannot keep up with the promises being made about tomorrow.

The technology side still hasn’t ironed itself out and may never with as saturated as the market is. With interest rates as high as they are and home prices through the roof, no one wants to pay a fortune for something that’s not rock solid. …That “sustainable” growth is only possible once all the artificial supports are knocked away and the technology proves viable and worth the cost once and for all.

Of course, the solar industry isn’t helped by the fact that the cost savings for customers aren’t quite as lavish as originally promised.

I wish we had home batteries. Right now, we have a natural gas driven Generac generator, which we purchased years ago. Back then, the disruptions from Commonwealth Edison's electrical feeds were intense, and nobody even thought of storing electricity in home batteries when the lights went out. What's holding us back now is the number of tall, huge, old trees surrounding our house, which shade the roof of our tall (basement, two stories, attic), old (built in 1886) house, making solar energy fairly illogical. Should we cut down the trees to get solar on the roof, or stick with the trees? Easy answer for us: we stick with the trees.

Excerpt from this story from Canary Media:

Batteries are all the rage — especially among homeowners who are going solar.

The percentage of people who install a battery alongside their new rooftop solar system is surging in the U.S., according to a new report from Lawrence Berkeley National Laboratory. 

That figure — known as the residential attachment rate — jumped from just under 10 percent in 2022 to 12.3 percent last year. This year, energy research firm Wood Mackenzie estimated that it will soar to 25 percent.

The surging interest in home batteries — which are almost always purchased to store power from solar arrays — comes as the country’s rooftop solar market craters. Installations are expected to fall by 19 percent this year, according to the Solar Energy Industries Association.

Policy changes in California, the nation’s biggest residential solar market by far, have a lot to do with both the contraction of the rooftop solar market and the rising popularity of home batteries. In April of last year, changes to the Golden State’s net-metering program took effect, slashing the rate at which rooftop solar owners could sell surplus power to the grid but boosting the value of batteries, which enable homeowners to save their solar power for the times when it’s most valuable. The attachment rate in California rose to 14 percent last year.

But other factors are driving the uptick in home battery installations as well. Extreme weather events, made more frequent by climate change, are increasingly threatening grid reliability. Batteries are becoming more affordable. And rising utility rates are making the economics of solar-plus-storage more attractive to homeowners.
