Local Knowledge About Inverters And Controllers

Conventional appliances and equipment and utility-supplied power use alternating current (AC) power and PV systems produce direct current (DC) power. Inverters are required to convert the power from the PV's from DC to AC. For practical reasons, including electrical code compliance and financing, it is best to have a conventional (AC) electrical distribution system in the house. This will permit the use of appliances, equipment, and lighting that is commonly available. Charge controllers regulate the voltage entering batteries to avoid overcharging. Electrical code requirements will apply to PV installations in regards to having fused disconnects, load centers, and proper grounding.
