Pilot Lamps
“
Batt. Full”
(Battery fully charged, green):
If it is lighting: Battery (batteries) has (have) been charged to 100 %, finished.
“>80 %”
(green):(MPPT5012A-DUO-BT)
If it is lighting: Battery has been charged almost fully. Solar controller is still in the charging constant voltage
“>80 %”
(green):(MPPT5025A-DUO-BT)
If it is lighting: Battery has been charged almost fully. Solar controller is still in the charging constant voltage
If it is flashing, frequency: 1time/s : controller over-heat
frequency: 2times/s: battery over-voltage. or PV over-voltage
"Charge"
(only MPPT5012A-DUO-BT, green):
If it is lighting: Charging
Off: Solar power is insufficient.
If it is flashing, frequency: 1time/s : controller over-heat
frequency: 2times/s: battery over-voltage. or PV over-voltage
“MPP”
If it is lighting: Proper functioning of the solar controller.
Short flashing: Display of readiness for service in case of missing solar power (at night).
“Batt. Low“ (yellow):
If it is lighting: Low voltage at main battery I. voltage<10.5V
The battery should be recharged as soon as possible!
All pilot lamps (5) are flashing:
The positions of the selector switches "MAIN Battery" are incorrect. For reasons of safety, the solar controller is switched-
off. Adjust the desired battery type according to table 1.
Operating Instructions:
Lifetime of the battery:
Recharge totally discharged batteries immediately!
Sulphation of the lead battery plates due to total discharge is to be prevented by soon charging, particularly in case
of high ambient temperatures. If the grade of sulphation is not too intensive, the battery can recover part of the
battery capacity after several charging/discharging cycles.
