External Regulator Check (see Cell/Regulator/Battery diagram)

Blocking Diode Check

1. Disconnect solar panel wires from external regulator. • Test with VOM for power at regulator INPUT position.

• If > ~ 5 V DC; regulator is bad, allowing panel to discharge the battery through regulator.

• If < 5 V DC; regulator is O.K.

Charge Control Check

1. Disconnect solar panel wires from external regulator and measure DC coming from unregulated panel.

• If sunny, ~ 18-22 V DC• If cloudy, < 14-16 V DC2. Reconnect wires from solar panel to regulator and disconnect

OUTPUT side wires from regulator to battery.• Test regulator output, even in full sun output < 16 V DC

Load Testing Batteries

• VOM check does not ensure battery is “good”. Battery should be removed from site, hard charged and then load tested by battery shop.

• Portable load testers can be purchased for ~ $50.00.Recommended as standard equipment for DC, DC/solar sites.
