By combining three 13.6 kWh aPower batteries with a single aGate controller, the Home Power system can provide up to 15 kW of continuous power and 40.8 kWh of usable energy, and a single aPower has a peak power output of 9 kW to handle large surges like an AC or freezer kicking on. Franklin Home Power specs
If the electrical load of a 10 kW PV system is 10 kW and the daily electricity consumption is 20 kWh, a battery with a capacity of 60 kWh is needed to store the solar energy generated. Calculation process: 1. Assuming 8 hours of sunlight per day, the theoretical PV generation is 10 kW × 8 hours = 80 kWh. 2.
You can utilize it with or without a battery backup system. Ideal for array designs where expansion is likely or when a battery storage system may be added later. Time-tested in off-grid systems.
