MARSTEK Venus E Gen 3.0 is a modern home energy storage system that allows you to store surplus energy (e.g. from a photovoltaic installation) and use it when it is most profitable or needed. The device is compatible with existing PV systems – no inverter replacement required. It is perfect for reducing daily electricity bills and as a backup power source during outages.

If the energy storage is to be used exclusively for self-consumption, it is necessary to install a dedicated meter that enables precise management of energy flows.

Thanks to the IP65 protection rating, the device is resistant to dust and water, allowing safe installation both indoors and outdoors.

This is a solution for people who want to increase their home’s energy independence, optimize energy consumption, and prepare for dynamic tariffs or rising electricity prices.

Energy storage is a modern way to increase energy independence and reduce electricity bills. Combined with photovoltaics, it allows you to store surplus energy and use it when solar production is low – for example in the evening or at night.

The key benefit is self-consumption, i.e. maximizing the use of self-generated energy. This reduces feeding electricity into the grid and avoids losses associated with prosumer settlements.

Modern solutions such as the MARSTEK Venus E Gen 3.0 make energy management even more effective – from automatic and AI modes to backup power in the event of an outage.

This is an ideal solution in times of rising energy prices and dynamic tariffs. The MARSTEK energy storage system not only increases self-consumption but also ensures energy security for your home or business.
