A typical 4kW residential array (ten 400W panels) works best with a 3. . The photovoltaic (PV) inverter is one of the two main components of a PV power generation system. An inverter's size directly affects how much load it can handle, how efficiently it operates, and how well it meets your energy needs. Accounts for safety margin and appliance surge factors. Formulas: Continuous inverter size = Load × (1 + margin). Surge is the maximum power that the inverter can supply, usually for only a short time (usually no longer than a second unless specified in the inverter's specifications).
