Solar battery sizing starts with your loads, not the advertised battery size alone. The SAKO SK-51.2V 320Ah is a useful example for understanding nominal energy, usable energy and system compatibility.
What does 16.3kWh mean?
Nominal energy is approximately 51.2 volts × 320 amp-hours = 16,384 watt-hours, or 16.384kWh. Usable energy is lower once depth of discharge and system losses are considered. The product listing states about 14.746kWh at 90% depth of discharge. That is a battery figure, not a guaranteed runtime for every installation.
Estimate your household demand
Multiply each appliance's power in watts by its daily hours of use, then add the results. For example, an average 1000W load running for five hours consumes about 5kWh before losses. Air conditioners and refrigerators cycle on and off, so measured usage is more useful than a simple label-based estimate.
Check inverter compatibility
This battery is listed at a nominal 51.2V with CAN and RS485 interfaces. Those details alone do not prove compatibility with every inverter. Confirm communication protocol, charge and discharge current limits, protective settings and wiring with the supplier or a qualified installer.
Checks before buying
- Account for peak power as well as total daily energy.
- Plan a dry, suitable installation space; the listing states an IP20 protection rating.
- Check mounting capacity, battery weight, cable sizing and protective devices.
- Confirm warranty terms and inverter integration.

Frequently asked questions
Will this battery run a home all night?
There is no universal answer. Measure the loads you intend to use overnight, account for losses and reserve a suitable margin. An air conditioner or heater can change the result substantially. Have a professional size the complete electrical system.
