A true all-in-one solar storage system for balconies and smaller homes

MARSTEK VENUS A combines an LFP battery, four MPPT controllers, AC inverter, BMS, smart controls and backup output. PV modules connect directly, so the system does not require a separate solar or battery inverter.

Four independent PV inputs make it easier to use panels with different orientation or shading. A supported smart meter follows household demand and helps limit exports.
