Frequently Asked Questions about the Marstek Venus-E

Can I use the Venus-E with my existing inverter?

Yes, the Marstek Venus-E works with any standard string inverter via AC coupling. So you don't need to replace your current inverter.

Do I need any additional products?

Yes, for the Marstek Venus-E to function optimally, a smart meter is required. You can choose from two compatible models:

  • Marstek CT002 – A 3-phase energy meter that measures instantaneous consumption and grid status via 3 separate measuring coils (CT coils). Suitable for situations where a P1 port is not available in the smart meter.
  • Marstek CT003 – An advanced 3-phase meter for the P1 port and IR interface , ideal for integration with smart meters and external systems.

Both smart meters ensure that the battery system can charge and discharge efficiently based on current consumption and generation.
