     * 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. ​ 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. ​
