How to choose the capacity of an energy storage system for a private home
The first question a homeowner faces is: how much energy should the system store? The answer depends on baseline consumption: lighting, refrigerator, boiler, pump, and other critical appliances that must keep working during outages.
For a small home, an ESS of 5–7 kWh is usually chosen — this is enough for backup power for the main appliances. If the goal is full autonomy together with solar panels, larger-capacity configurations are worth considering.
The advantage of Sunwoda modular systems is that capacity can be increased gradually: start with a base unit and add modules as needs grow, up to 60 kWh.
Compatibility with the inverter is equally important. Sunwoda batteries work in tandem with almost all popular inverters on the market, so the system is easy to integrate into an existing solar power plant.
