Oversizing panels to inverter capacity is a standard procedure, i. This allows the best possible output on cloudy months or mornings without engaging inverter over-voltage limits. . Consequently, inverter sizes vary greatly. Additionally, you'll learn what appliances you can power and how you can select. . 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). Some appliances, particularly those with electric motors, need a much higher start up surge than they do when running. 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 consumption. The power is typically measured in **Watts (W)**.
