Description
High-performance LiFePO4 storage battery for low-voltage photovoltaic systems. With a nominal voltage of 51.2V and a capacity of 100Ah it stores up to 5.12kWh of solar energy, optimising self-consumption and reducing energy costs.
The glossy glass-effect design with a white finish gives it an elegant look, ideal for indoor installations and premium residential settings. It integrates a touch LCD display and WiFi for monitoring. It is ready to use and requires no special configuration.
Safety and durability
LiFePO4 technology guarantees more than 6,000 cycles of charging/discharging and a 10-year warranty. The integrated BMS manages alarms and system protections. Standard current 90A, maximum continuous 100A, peak power 4.8kW. The IP20 rating means it must be used indoors only.
Installation and expandability
Can be surface- or wall-mounted using the brackets supplied. Up to 15 batteries can be connected in parallel per inverter, with no need for an HV Box, subject to checking the maximum capacity supported by the inverter. Connection cables included.
