Marstek Venus A Home Battery – 8.48 kWh (4 modules)

This set consists of a Marstek Venus A base module with three expansion modules, together 8.48 kWh of storage capacity. Suitable for households with higher consumption or a larger solar panel installation that generates a lot of surplus energy.

The Venus A works fully plug & play via an ordinary wall socket and is modular, built from 2.12 kWh modules. The system can later be expanded further to a maximum of 12.72 kWh.

The battery uses LiFePO4 cells for safety and a long service life. Via the P1 meter or kWh meter, the battery automatically responds to your own consumption and so limits grid export.

Capacity: 8.48 kWh (4 × 2.12 kWh) · Expandable to 12.72 kWh · Battery type: LiFePO4 · Connection: plug & play via wall socket

How to connect it

  • Plug into a wall socketPlug it into an earthed wall socket and you're done. No installer needed.
  • Connect solar panels directlyFour MPPT inputs, together about 1.4 kW. You connect your own panels directly to the battery.
  • P1 meter or kWh meterChoose a P1 meter (CT003) or kWh meter (CT002) when ordering; if you already have one, you can do without. The P1 meter goes on the P1 port of your smart meter. No P1 port? Then the kWh meter measures in the electrical panel.
  • Connectivity and mountingWi-Fi or LAN for the app. Four stackable 2.12 kWh modules, about 164 kg in total.

When 800 W and when full power?

In the Netherlands, a battery connected via a wall socket may supply a maximum of 800 W to your home. For an average household, that covers the base load: fridge, lighting, TV, laptop and router. If the washing machine, oven or induction hob run at the same time, the rest simply comes from the grid.

The Venus A complies with this: via the wall socket it supplies a maximum of 800 W to your home.

In addition, it charges directly from your own solar panels via four MPPT inputs, together about 1.4 kW. During a power cut, the backup output (EPS) supplies 1,200 W to the appliances you connect to it.

Questions about this product

Can I connect this battery myself?
Yes. A plug-in home battery is plug & play: the plug goes into an earthed wall socket, you don't need an electrician and nothing needs to be done in the electrical panel. Output of this model: 1200 W.
How much may I feed back via the wall socket?
In the Netherlands, a battery may supply a maximum of 800 W to your home via an ordinary wall socket. If you want to use more power, a dedicated circuit is needed — have it installed by an electrician. Register your installation with your grid operator.
How much energy does this battery store?
The battery has a capacity of 8.48 kWh. It can be expanded up to 12.72 kWh. An average Dutch household (2,430 kWh per year, Milieu Centraal) uses around 3 to 5 kWh in the evening and at night; use this to estimate how much of your consumption it covers.
Does it work during a power cut?
This model has a backup power function: 1200 W. Devices you connect to that output keep running if the grid goes down. Your whole house will not automatically run on it — that requires a fixed installation with a changeover switch.
Can I have the battery charge on a dynamic energy contract?
Yes. In the app you set when the battery charges and discharges: manually, on a fixed schedule, or automatically during the cheapest hours of the day.
How much space do I need?
Weight: ~164 kg. Choose a flat, dry spot. Not sure whether it fits? Send us a photo on +31 10 261 33 86.
