The PV system is used to operate building electrical loads; any problems with the loads will affect the system as well. The first step is to check the load switches, fuses and breakers with the multimeter to see if the proper voltage is present at the load's connection. Next, use the multimeter to check the fuses and circuit breakers. If you find blown fuses or tripped breakers, locate the cause and fix or replace the faulty component. If the load is a motor, an internal thermal breaker might be tripped or there might be an open winding in the motor. For testing purposes, plug in another load and see if it operates properly.
As with any electrical system, check for broken wires and any loose connections. Clean all dirty connections and replace all bad wiring. With the power off, check for and repair any ground faults. If any fuses or breakers blow or trip again, there’s a short that you need to locate and repair.
If the load still does not operate properly, use the multimeter to check the system's voltage at the load's connection. The wire size may be too small and need to be increased. It may also be possible that the wires running to the loads are too long. This will show up as a low voltage at the load. In this case, you can reduce the load on the circuit or run a larger wire.
