PV Inverters

The batteries in your PV systems store direct current (DC) power which can be used for certain applications but most of the conventional household appliances use alternative current (AC) power. The Inverter converts low voltage DC into higher voltage AC. 

Electricity transmits more efficiently at higher voltages and it's the standard used worldwide. 120 or 240 volt in the USA at 60 cycles per second. Inverters are available in a wide range of wattage capabilities. 

Brand-name inverters are highly reliable. Efficiency averages about 90% for most models, check the CEC certification before you purchase. Poor performance and high failure rates are common with cheap imported inverters without CEC certification.

Inverter Operation

Early inverters produced a square wave alternating current which at times resulted in problems while operating with solid-state equipment.
