Application scenarios
Energy Storage Supporting Household Photovoltaics
It solves the pain point of photovoltaics where "electricity generated during the day is wasted and there is no electricity at night". A single 10.24KWh unit can meet the basic electricity needs of a family for 2-3 days, supporting parallel expansion of up to 15 units. The LiFePO4 battery cells are safely suitable for indoor installation, and a custom charging and discharging strategy can save 15%-20% of electricity bills.
Emergency Power Supply for Small Commercial Places
Suitable for convenience stores and small offices, the 5KW power can drive refrigerators and cash register systems. It features natural cooling, is maintenance-free, and takes up no space. Connecting to an energy management system allows real-time monitoring of the backup duration, avoiding losses caused by power outages.
Energy storage:When the power supply is sufficient, the wall-mounted energy storage battery converts alternating current (AC) from the power grid into direct current (DC) through a charger or inverter and stores it in the internal battery.
Batteries usually adopt lithium-ion battery technologies such as lithium iron phosphate (LiFePO4), ternary material (NMC), etc. These batteries have the characteristics of high energy density and long lifespan.
-
Energy management:The Battery Management System (BMS) monitors the state of the battery, including parameters such as voltage, current, and temperature, and optimizes the battery's charging and discharging process through algorithms to ensure the safe and efficient operation of the battery.
The BMS includes various protection mechanisms such as overcharge/overdischarge protection, over-temperature protection, and short-circuit protection. -
Energy conversion:The inverter converts the direct current (DC) stored in the battery into alternating current (AC) for use by household appliances.
The inverter is also responsible for ensuring the quality of the output electrical energy, such as voltage stability and accurate frequency. -
Energy release:When power demand increases or supply is insufficient, the wall-mounted energy storage battery converts the stored direct current into alternating current through the inverter and outputs it to terminal devices for use through sockets or other interfaces.
Through intelligent algorithms, the Energy Management System (EMS) can dynamically adjust the charging and discharging strategies according to electricity prices and grid demands to maximize economic benefits.
