* size the inverter to meet the needs of your biggest loads. Oversizing wastes power because bigger inverters have more parasitic draw. It may be worthwhile to have a small inverter for small loads and a big inverter for big loads; this stops the inefficient use of small loads on a big inverter. | * size the inverter to meet the needs of your biggest loads.
