Many Ukrainian families already own a generator and wonder whether they still need it once they install solar. They do, but it will work very differently.
The role of each source
- The sun is the main source by day and the cheapest energy.
- The battery is the instant backup and the energy for evening and night.
- The generator is insurance for long outages in cloudy weather.
How they work together
A hybrid inverter manages all sources on its own. When the grid is down, the house runs on sun and battery. If the battery is low and there is little sun, the inverter signals the generator to start, and it charges the battery. As soon as the battery is full, the generator stops.
Why this saves money
A generator is most efficient under a steady load. When it charges the battery at full power for an hour instead of running all night for one fridge, it burns several times less fuel, with less noise and wear.
What you need to connect it
- An inverter with a generator input.
- A generator with stable voltage: an inverter generator or one with a good regulator.
- For automatic start, a generator with an electric starter and an auto-start module.
If you already own a generator, we will include it in the plant design.
