Troubleshooting
Charging not indicated on display when solar panel is
connected.
Reverse polarity.
Correct the polarity.
Loose connection.
Secure connection(s).
Not enough sunlight.
Reposition solar panel.
No output on load connections.
Load switch off.
Press the load on/off switch.
Battery not connected, loose connection or wrong polarity.
Connect a battery to the regulator, check correct polarity
and secure connection.
Polarity load reversed.
Correct load polarity.
Over-discharge protection enabled.
Disconnect load and fully recharge battery.
Short circuit or overload protection enabled.
Verify that load is not short-circuited and draws no more
than 30 A. Press the load on/off switch when everything is
OK.
