The SolarEdge Nexis Battery Block is a modular high-voltage LiFePO4 battery module for the SolarEdge Nexis system. One block has 4.9 kWh nominal and 4.65 kWh usable energy. Its continuous charge and discharge power is 3.5 kW, with a 5.3 kW peak for 10 seconds.

A Battery Stack holds 1 to 4 Battery Blocks and always needs one Nexis Battery Link. An inverter supports up to 16 blocks in up to 4 stacks. The blocks connect to each other and to the Battery Link with the Simple-Click self-locking connection. It works with both the single-phase and the three-phase Nexis inverter.

Each block has its own power module (Battery Optimizer) and ThermoShield technology, which is designed to stop thermal runaway spreading from cell to cell. The enclosure is rated IP65 for indoor or outdoor use. One block measures 668 x 194 x 374 mm and weighs 55 kg. It can stand on the floor or hang on a wall with a bracket sold separately.
