Pilot Lamps:
"Battery Full" (Battery Board I fully charged, green):
If it is lighting: Battery (batteries) had (have) been charged to 100 %, trickle charge U2 and storage charge U3, finished.
If it is flashing: Main charging process is effected in the charging phase U1, indication of charging state of approx. 75 %
(lead) / 90 % (LiFePO4). Gradual increase to 100 % (long flashing).
Off: Main charging process is still being executed in the phase I.
"Main Charging" (Main charging, yellow):
If it is lighting: Main charging process is effected in the phase I and after that in the charging phase U1.
Off: Trickle charge U2 or storage charge U3.
If it is flashing: 1. Battery temperature sensor is not connected with characteristic lines of charging LiFePO4!
2. External battery overvoltage > 15.5 V delay 20 s,
automatic reset < 13.2 V (depending on type), delay 30 s.
"Current" (Charging current, red):
If it is lighting: The lighting intensity of the LED "Current" will be reduced or increased depending on the supplied
charging current.
Off Charging current is less than approx. 0.2 A
"Board I" (Board battery, yellow):
If it is lighting: Charging and control of the supply battery.
Off: Charging port is blocked (safety switch).
If it is flashing: 1. Battery Protection: battery overtemperature (or LiFePO4 under -20° C),
switchover to low safety charging voltage and half of the max. charging current.
Automatic return, as soon as the temperature is 2 °C less.
2. Charging lock input "Sw" had been activated by the battery BMS, only LiFePO4 battery, see page 12.
If it extinguishes shortly every 2 sec.:
Only LiFePO4: Battery temperature below 0 °C. The charging current can be reduced for battery
protection during all modes of charging. If batteries are discharged, longer charging times.
"B2B" (Charging converter, green):
If it is lighting: Driving mode, the charging converter charges from the starter battery to the board battery.
If it is flashing: Operating voltage at terminal "Start II" is too low. Thus, the power control of the charging
converter had reduced the output capacity by more than 30 %.
Off: Charging converter is switched-off.
"Solar" (MPP Solar Controller, yellow):
If it is lighting: MPP control of the solar controller is active and works properly. AES is not active, yet.
If it extinguishes shortly every 2 s:
Sufficient excess solar power is available, the output "AES" for automatic energy selection of
the refrigerator is activated.
Short flashing every 5 s: Display of readiness for service in case of missing solar power (at night).
If it is flashing: Solar voltage at terminal "+Solar Panels" too high.
"Care" (Battery care, green):
If it is lighting: Equalization charging of the battery cells in the progressed charging phase U2, storage charge U3.
If it extinguishes shortly every 2 s: Lead battery regeneration or Lithium Auto Wake Up is activ.
Short flashing every 20 s: Without charging source, the pulser trains the (lead) battery Board II with current pulses.
Off: Charging process is still in phase I, U1 or beginning of the phase U2.
"Power" (Mains, red):
If it is lighting: Mains charging mode is active.
Off: No connection to mains.
If it extinguishes shortly every 2 s:
"AC Power Limit" is active. The Mains charging capacity is limited. Silent Run (nighttimes).
Short flashing every 2 s: "AC Power Off". Solar has priority. Automatic mains charging in case of insufficient solar power.
If it is flashing: 1. Disconnection of safety timer, duration of the charging phase I was too long, too many consumers,
battery defective (short-circuit of the cells). Reset is only possible by withdrawing the mains plug.
2. Internal unit failure (overheating), automatic reset after cooling down.
All LEDs "Battery Full", "Main Charging", "Current", "Board I", "B2B", "Start II", "Care", "Power" are flashing simultaneously:
The positions of the upper 4 selector switches "Board I" are incorrect. For reasons of safety, the unit gad been
switched-off. Set the desired battery type according to page 9 "How to set the battery type "Board I"- (Design,
Technology)".
During power pack operation (without batteries or with defective fuse) the active charging ports provide the desired charging
voltage. The LEDs "Board I", "Start II" and "Battery Full" are still lighting.
