2019 Good Design Award Winner Lithium-ion Storage Battery AC50

Our main supplier, Taiwa Electric, has restocked the essential protection relay set for complete self-consumption/on-site PPA that we primarily use on rooftops! This set can be easily installed from the front without the hassle of cutting the panel and assembling it from the back, as was required with previous models. Additionally, it allows for the setting of C contacts, making installation and configuration on-site simple and exceptionally reliable, making it a popular model. When we use it for complete self-consumption projects, we rely on it almost 100%, and as usual, we have ordered a bit more than necessary, so if anyone needs it, please let us know. We will offer it at a friendly industry price. Our main business has shifted to "grid-connected battery storage," retrofitting battery systems for existing demand facilities, and retrofitting battery systems for FIP transfers, but we still receive quite a few requests for complete self-consumption/on-site PPA projects. After all, with rooftop installations, there are no renewable energy surcharges, fuel cost adjustments, or transmission costs! Complex energy designs with various vectors (directions of electric flow/arrows) are our specialty, so please feel free to consult with us.

SequencEnergy Co., Ltd. will be exhibiting at the online exhibition "Solar Summit" for solar power generation and storage business negotiations, which will be held from March 30 (Wednesday) to April 1 (Friday), 2022. We plan to provide information on various storage systems, various self-consumption systems, and measures related to the upcoming liberalization of the power transmission and distribution business under the "Energy Supply Resilience Act." For visitor information, please visit: https://exhibition.showbooth.dmm.com/events/solar2203/ *Entry to the "Solar Summit" will require the email address and password you registered on the official website. You may enter and exit freely. 【Contact Information】 SequencEnergy Co., Ltd.

Right now in Japan, policies are being promoted to increase and expand both "renewable energy (mainly PV and then offshore wind power)" and "nuclear power generation," but this is actually impossible. The reason is that these two—"renewable energy (mainly PV)" and "nuclear power generation"—are like a seesaw; if one increases, the other decreases. In simple terms, it's because "renewable energy" is an unstable variable power source, while "nuclear power generation" is a stable power source. It seems that the current voices of the Japanese people are leaning towards the stable "nuclear power generation." But is it acceptable to leave behind something whose disposal method is not even known for tens of thousands of years to future children and grandchildren, while only we who live in the present enjoy that stability? This is where "grid-scale batteries," which can stabilize unstable "renewable energy," come into play. In South Australia, approximately 85% of the state's energy comes from "renewable energy," yet by distributing "grid-scale batteries," they support the state's energy infrastructure as a stable power source without any blackouts. By keeping the existing power grid as it is, grid-scale batteries can stylishly pass the baton to the next generation and save the planet.

The business model we are currently promoting explosively, called "grid-connected storage batteries," is completely different from the traditional methods of securing power during disasters or economic measures during normal times. It is a business model that directly connects to the power grid for charging and discharging. However, the truth is that this "grid-connected storage battery"... It buys electricity when prices are low and charges, and sells when prices are high and discharges. Therefore, when prices are low, which means when there is excess electricity and output control is in effect, it charges. Conversely, when prices are high, which means when there is a shortage of electricity and stable supply is disrupted, it discharges. Thus, the expansion of "grid-connected storage batteries" is the most effective measure for stabilizing the current electricity supply and demand. In South Australia, 85% of the state's power comes from renewable energy, yet the grid continues to operate normally without interruptions (without blackouts). This is something that was previously considered unthinkable based on conventional wisdom. What makes this possible is the "grid-connected storage battery equipped with GFM inverters." The fact that this business significantly contributes to solving current issues while also aiding the expansion of renewable energy to combat global warming is something we can take pride in. This business model of "grid-connected storage batteries" can truly be called a proud existence, akin to a savior.
