PV battery storage
or start without grid-operator registration
Use more of your own solar power – with a new system without grid-operator registration, a retrofit, an expansion or agricultural battery storage.
Find the right solutionRequest a system reviewMore self-consumption. Less grid electricity.
Use surplus electricity in the evening, at night or on the farm – and market it at exchange-based prices with larger agricultural storage systems.
Which storage solution fits?
Start a PV system with Victron without grid registration
From around 10 kWp, three MultiPlus-II units, battery storage and a safe changeover switch can supply a home or business without registration with the grid operator.

Victron or a hybrid inverter?
Add Victron and keep the existing PV inverter – or replace an ageing inverter with a hybrid inverter.
Compare both options
Expand battery capacity
Add compatible battery modules or another storage tower and use more of your own solar power.

Agricultural storage for your farm
Combine self-consumption, peak shaving, backup power and exchange-based electricity marketing.

Three MultiPlus-II units provide three-phase power – including heat pumps and three-phase equipment.
High self-sufficiency
Depending on the design, the system can supply a home or business independently for extended periods.
Automatic changeover
When your own electricity runs low, the changeover switch transfers the supply safely and quickly to the grid.
Recharge the battery
The PV system recharges the batteries until the Victron system takes over again.
Strictly separated
The public grid and the Victron system are never connected at the same time, so registration with the grid operator is not required.
The only formality: register once in Germany’s Market Master Data Register (MaStR), normally in just a few minutes online.

Victron or a hybrid inverter?
Keep a working PV inverter or replace an ageing one.
Add a Victron battery inverter
The PV system remains unchanged. This is usually the simplest and most cost-effective solution.
Install a hybrid inverter
If the PV inverter is ageing or due for replacement, a hybrid inverter combines PV generation and battery storage in one system.
Expand battery capacity
Use more of your own solar power by adding battery modules or another storage tower.
Increase self-consumption
Use more solar power in the evening and at night.
Supply new loads
Integrate an EV charger or heat pump more effectively.
Expand modularly
Add modules or another storage tower.
Check compatibility
Check the product series, age and system before ordering.
