Energy
Electricity is a vital part of our daily infrastructure. Especially during disasters or in times of rising energy costs, securing a stable power supply is essential. Our energy solutions meet a wide range of needs and scenarios.
Features
Surplus solar energy can be stored in batteries for later use. By deciding how the solar panels and battery storage are controlled to match your usage pattern by season and time of day, cost-effectiveness can be optimized.
After the Feed-in Tariff (FIT) period ends, selling electricity becomes less profitable. Consuming your own generated electricity during peak rate hours can lead to significant savings. In most cases, existing solar panels can continue to be used.
Our hybrid inverters feature two solar PV inputs, enabling flexible solar configurations. They support up to 10kW, making them compatible with most residential panels.
Even in extended outages, a combination of solar power and battery storage ensures a continued power supply. Unlike standalone batteries, which rely on grid recovery, solar-equipped systems can provide electricity on sunny days. Additionally, integrating gasoline or diesel generators adds another layer of resilience when neither solar nor grid power is available.
AI can analyze market conditions such as 30-minute electricity market prices together with sensor outputs such as outdoor illuminance, and decide charge/discharge timing in real time to optimize electricity costs.
Supports single-phase 100/200V as well as three-phase 200V (industrial). Ideal for homes and small businesses; installed at a factory in Nagano Prefecture as a solar power and battery system.
Products
Our hybrid inverter converts solar energy into usable 100V or 200V power for home appliances and air conditioning. It supports single-phase 2-wire and 3-wire systems, making it compatible with most Japanese households.
Surplus solar energy is stored in batteries for nighttime use. If battery power is unavailable, the inverter automatically switches to grid power. The 10kW output ensures stable power for typical households.
The system allows timed charging from the grid in up to three time zones, ideal for households with time-of-use plans. Charging current can also be limited to prevent breaker trips.
Communication with the battery’s BMS ensures optimal system management and performance.
Our lithium iron phosphate (LiFePO4) battery connects to the hybrid inverter, storing solar energy for nighttime use. Compared to conventional lithium-ion batteries, it offers superior safety and thermal stability.
Each unit provides 5.12kWh (100Ah) and can be placed neatly along walls due to its compact design (less than 20cm deep). Up to 15 units can be connected in parallel, so capacity can be expanded later without replacement. The battery units communicate with each other and with the inverter via BMS, enabling intelligent charging/discharging control.
For households with higher consumption or evening peak usage, we recommend installing 10kWh or more for maximum savings.
