| Problem | Cause | Corrective action |
| 1. No inverter output voltage. The inverter does not work, or just for a few seconds | Battery voltage may be too low. Low voltage cut-out switch trips at 10V (12V), 20V (24V) or 40V (48V). |
Recharge battery for 24 hrs |
| Battery connections are corroded | Check for corrosion, and replace bad sections | |
| Check if the inverter is overheated. In case of overheating LED of temperature + failure lights up | Disconnect connected load. Improve ventilation | |
| Overload or short circuit | Disconnect excessive load | |
| LED overload + failure will be lit | Remove short circuit condition | |
| 2. Battery charger does not operate | AC voltage not supplied | Check system The AC green LED should light up, if power is supplied |
| Input voltage too low | Check fuses or magneto-thermals | |
| The battery charger will not operate below 160/80V | Check the generator output voltage, remove connected load, output voltage should come up | |
| 3. The battery charger does not operate, while mains voltage is present | Mains frequency could be too high or too low | Check the generator output frequency |
| The frequency must be within 35-66 Hz | Check generator rpm | |
| 4. Batteries not fully chargede | Charge current too low | See “charge current too low” |
| Current to load too high | Decrease the battery load | |
| Charge time too short | Replace the battery | |
| Battery temperature too low | Use temperature sensor | |
| Defective battery (short circuit in cell) | Replace the battery | |
| 5. Battery loses charge quickly | Battery capacity reduced because:
|
Replace batteries |
| Charge/discharge several times, this might help, otherwise replace batteries | ||
| 6. Batteries are warm | Defective batteries (short circuit in cell) | Replace batteries |
| Battery temperature too high | Use temperature sensor | |
| Charge voltage too high | Check the switches setting |
