Capacity calculation of photovoltaic inverter
The inverter capacity is calculated by adding the load to 20% of the load. For example, if the load is 1100W, then the inverter capacity would be around 1320W.

AC Inverter Capacity (kW) = DC Input Power (kW) / Inverter Efficiency (%).
In order to accurately size your inverter, here is a very simple formula: projectiles Inverter Size = Total Solar Panel Output after losses or Desired battery output if there is any.
Installers typically follow one of three common solar inverter sizing ratios:Aggregate panel wattage x 1.25Aggregate panel wattage x 1.3Aggregate panel wattage x 1.35.
Once you have the max Voc of one panel, all you have to do is divide your inverter maximum voltage by this value, and then round down to the nearest whole number.
