The 54 panels total 33.48kW DC at STC. Battery storage is measured separately: the three batteries total 43.02kWh of nominal energy. Solar capacity, inverter output and battery energy describe different parts of the system.\u003c\/p\u003e\n\u003ch3\u003eWill the batteries supply 18kW continuously?\u003c\/h3\u003e\n\u003cp\u003eThe inverter's 18kW rating does not guarantee 18kW of battery-only output. Available power depends on battery voltage, BMS limits, inverter current limits, temperature and conversion losses. The three batteries have a combined recommended charge\/discharge current of 300A, while the inverter lists a 334A maximum. Your installer must set limits for the complete system.\u003c\/p\u003e\n\u003ch3\u003eHow long will 43.02kWh of battery storage last?\u003c\/h3\u003e\n\u003cp\u003eRuntime depends on the connected loads and usable energy. The datasheet discharge-energy figures total approximately 40.87kWh at 95% depth of discharge, before inverter losses and any additional reserve. For an estimate, divide the energy available to your AC loads by their average power consumption in kW. Heating, pumps and other high-demand loads require a load assessment.\u003c\/p\u003e\n\u003ch3\u003eAre the Canadian Solar 620W panels bifacial?\u003c\/h3\u003e\n\u003cp\u003eYes. The CS6.2-66TB-620H panels use bifacial TOPCon cells and a dual-glass construction.
