The Venus E, Venus E Mini, Venus A and Venus D are plug-in home batteries: plug into an earthed socket and the battery supplies a maximum of 800 W to your home via the socket. You will find them among the plug-in home batteries. The Venus X is a fixed home battery for the electrical panel, found among the fixed home batteries. Also read plug-in or fixed: which home battery suits you.

Connect it yourself or have it installed?
You connect the plug-in models yourself; via the socket a limit of 800 W applies in the Netherlands (read is an 800 watt plug-in home battery allowed). For the full power of the Venus E 4.0, E Mini or Venus D, an installer connects the battery to a dedicated circuit. The Venus X is always permanently connected by a certified installer; in the Netherlands installation is arranged via a quote. To control the battery based on your consumption, you use a P1 smart meter dongle or CT clamp, see P1 meter or CT clamp with a home battery.
Expanding and choosing capacity
The Venus A and Venus D are modular: you can add modules later with the Venus A expansion module (+2.12 kWh) or the Venus D expansion module (+2.56 kWh). With the Venus E 4.0 you can link up to three units using the optional SmartBox. See also expansion modules and how many kWh of home battery do you need. Venus E 3.0 or 4.0? Read the differences.
Frequently asked questions about Marstek
Do I need a P1 meter with a Marstek home battery?
