  • Expandable capacity: 4.24 kWh (2 modules) for extra autonomy.
  • Plug & Play: Works with any PV system without a new inverter.
  • Integrated solar energy: 4 MPPTs up to 2.4 kWp PV input.
  • Fast backup: EPS switches over within 15ms when power fails.
  • Smart energy management: AI-driven with zero injection via smart meter.
  • Safe and durable: LiFePO4 > 6000 cycles, IP65, suitable for indoor and outdoor use.

Why choose the Marstek VENUS A with 1 extra battery?

This configuration offers an ideal entry point for households looking to increase their self-consumption. Thanks to its compact and modular design, the system can be easily expanded as your energy needs grow. The AC-coupled technology ensures seamless integration with your current solar panels, while the intelligent software optimizes your energy consumption based on current market prices.

Important: A smart meter is required for proper operation. For 1–3 units per phase, one smart meter is sufficient.
