Hybrid Inverter
Inverter that combines PV electricity generation, battery storage, and grid feed-in in a single device.
Also known as: Storage Inverter, Battery Inverter
What Is a Hybrid Inverter?
A hybrid inverter combines the functions of a PV inverter and a battery charger in a single device. It can simultaneously convert solar electricity into alternating current, store excess energy in a battery, and release it on demand.
How It Works
The hybrid inverter intelligently controls the energy flow between three areas:
- Solar modules — DC electricity is received
- Battery storage — surplus is charged, discharged when needed
- House grid / electricity grid — AC electricity is provided or fed in
Many devices also offer a backup power function (emergency power) that maintains supply during grid outages.
Typical Specifications
| Property | Value |
|---|---|
| PV power | 3—12 kW |
| Battery power | 3—10 kW |
| Efficiency | 95—97% |
| Backup power switchover time | under 20 ms |
Advantages and Disadvantages
- Advantage: One device instead of two, compact installation, optimised energy flows
- Disadvantage: Higher purchase cost, if the unit fails the entire system is affected
Practical Tip
If you are planning a PV system with storage, a hybrid inverter saves installation costs and space. A later battery retrofit is also possible if the inverter is battery-ready.

String Inverter
Central inverter that converts the direct current from one or more series-connected module strings into alternating current.
Battery Storage
Energy storage for PV systems that stores surplus solar electricity and releases it on demand.
Self-Consumption
Share of self-generated solar electricity consumed directly in the household rather than fed into the grid.
AC/DC (Alternating Current/Direct Current)
AC (Alternating Current) is the mains electricity from the grid, DC (Direct Current) is produced by solar modules and batteries.
