This energy storage system can provide power to connected loads using photovoltaic power, utility power and battery power and store surplus energy generated from solar photovoltaic modules when needed. When the sun has set, power demand is high, or there is a power outage, you can use the energy stored in this system to meet your power needs at no additional cost. Furthermore, this energy storage system helps you pursue the goal of energy self-consumption and ultimately energy independence. Depending on different power situations, this energy storage system is designed to generate continuous power from solar photovoltaic modules (solar panels), battery and utility. When the MPPT input voltage of the PV modules is within the acceptable range (see specification for details), this energy storage system is only compatible with single crystalline and polycrystalline PV module types.
