Retrofit or Expand PV Battery Storage
Retrofit PV battery storage
and expand
or start PV 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 solutionBook a phone appointmentMore self-consumption. Less grid electricity.
Use surplus electricity in the evening, at night or in your business – and with large agricultural storage systems, market it at exchange-based prices.
Which storage solution fits?
Start PV with Victron without grid-operator registration
From around 10 kWp, three MultiPlus-II units, battery storage and a safe changeover switch 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 business
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.
In Germany, the only formality: register once in the Market Master Data Register (MaStR), normally in just a few minutes online.
Request a system reviewView Victron systemsVictron 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.
