System Information Your chosen system consists of a KODAK Solar Off-Grid Inverter 1.5kW 24V inverter with 4 Seraphim SIV Monocrystalline Series 550Wp Silver Frame modules and Hubble Lithium AM4 2.7kWh 25.5V Battery.
This system can discharge a maximum 1575W of AC energy for powering household loads. If fully charged, the battery would sustain that rate for about 1 hours. In order to maximise the performance of the system, it is best to discharge the battery slower by avoiding high peak loads. This system would power typical household loads of 1kW for about 2.64 hours.
If your customer requires their battery capacity to last for longer, consider selecting a higher capacity battery, or increasing the quantity of PV modules would increase the amount of energy available to charge the battery.
