Battery voltage.
Load on/off switch [3] has no function.
Output current from battery to DC-load.
Indicates 0.00A when load is switched off.
Use the Load on/off switch [3] to switch the output current to the
load on or off.
Note: in over-discharge protection mode trying to switch on output
to the load will fail and a buzzer will sound. When the system
recovered from over-discharge protection mode (battery charge level
back to normal) press the Load on/off switch [3] 2 times to
restart output current to the load.
Charging current from solar panel to battery
Load on/off switch [3] has no function.
Possible cause Possible solution
1. Correct polarity
2. Secure connection(s)
3. Reposition solar panel
1. Press switch [3]
2. Connect a battery to the regulator,
check correct polarity and secure
connection
3. Correct load polarity
4. Disconnect load and fully recharge
battery
5. Verify that load is not short circuited and
draws no more than 30A. Press switch [3]
when everything is OK.
