Sourcing and delivery under one contract
ES-LV-16 stores solar energy and supplies it through a compatible external inverter for residential or commercial backup systems. Its BMS manages the cells, while the built-in aerosol fire extinguisher complements electrical and temperature protection. The IP20 enclosure is intended for a dry, protected indoor location. Inverter communication and charging settings must be matched during system design.
