Battery and power electronics in one slim unit
MARSTEK VENUS E Mini is an all-in-one home energy storage system combining an LFP battery, bidirectional AC inverter, controls and backup output. It can store low-cost grid energy or surplus from an existing PV installation for later use.

Ideal for
- homes seeking compact storage for a 230 V installation

- dynamic tariffs and time-shifting energy use
- backup of selected appliances through the dedicated output
