How big an inverter should a 70kW solar power station use
Generally, it's recommended to size the inverter to 80-100% of the DC system's rated capacity. Before determine the inverter size, the most important thing is to calculate your average daily power consumption (kWh) and calculate your solar panel array size to match your power. Your inverter needs to handle every watt your loads demand simultaneously -- both the steady continuous draw and the brief high-power surges when motors start. Undersizing means tripped breakers and failed startups. This guide walks through the sizing. Right-sizing a solar inverter aligns the DC array and the AC conversion stage so the system runs in its most efficient operating band for more hours. Let's say you have a 6kW solar array (twenty 300-watt panels).
