want to keep running.
Refrigeration, lighting, internet, pumps and HVAC have different power needs. We review both the energy capacity in kWh and the output in kW so the proposed battery can support the intended loads.
Backup duration varies with consumption, battery state of charge, solar availability and system configuration. Whole-home backup requires a load and service assessment.
