There Is No AC Power

The AC power (household 110 Volt power) is produced by the inverter from the DC power in the batteries.  Here are a few things to check if there is no AC from the inverter.

1. INVERTER --- Make sure inverter switch is ON.  Some inverters have several switch positions, on for on/off, one for a remote control, etc.  Be sure all switches are in the right position.  Inverters are equipped with safety controls which turn them off if they are too hot, batteries get too low, etc.  Most reset when the problem is corrected, ie. unit cools off or batteries recharge.   Read the manual for your inverter for details.
2. CIRCUIT BREAKER --- The batteries connect to the inverter through a 250 Amp circuit breaker on most of the units.  If this circuit breaker is OFF, the system is OFF.  This circuit breaker is larger than the 20 Amp unit that connects to the solar panels and charge controller.
3. WIRING --- Of course check for loose or corroded connections
