Collection: Plug-and-Play Batteries for Existing & Balcony Photovoltaic Systems

Plug and play batteries to add storage to an existing or balcony solar system without rebuilding it: Marstek Venus A all-in-one units of 2.12 kWh with four MPPTs, Venus X of 10 kWh and 6 kW AC-coupled, Venus E Mini of 2 kWh for wall mounting and Venus E 3.0 of 5.12 kWh, plus Growatt AURA batteries and Hoymiles HiBattery modules.

The difference lies in the connection point: AC-coupled models sit after the existing inverter and require no work on the strings, units with a built-in MPPT accept the panels directly. To optimise, you need an energy meter reading the grid exchange.

Installation with no building work, LiFePO4 cells and modular expansion.
