29/85 V 1.0
44 Trouble shooting
Warning – Never remove the cover of the inverter! Do not self repair the inverter, no serviceable parts are
inside the unit.
No function
Check LED-Display to identify the reason.
According the failure indicated by the display see sections below to solve the problem.
Check wiring for correct size, damage or loose screws.
Check batteries, battery fuse or fuse installed on AC-output.
DC-Low voltage
The battery voltage dropped below 1.75V/Cell.
Check battery fuse.
Charge the battery – if charging is not solving the problem maybe the battery is defect.
The wiring may be too thin or check installation for loose connections.
Note: If battery voltage rises above 2.1V/Cell, the inverter restarts automatically.
DC-Over voltage
The battery voltage is above 2.55V/Cell.
Remove the battery charger and stop charging the battery.
Note: If battery voltage is dropping below 2.5V/Cell the inverter restarts automatically.
Over temperature
If load is smaller than nominal power of inverter – check if ventilation of the inverter is
blocked. Maybe the ambient temperature is too high.
If load is exceeding nominal power of inverter – reduce the load.
Note: The inverter will switch on automatically if temperature of the inverter is within
normal operating temperature range.
Overload
Reduce load. Remove unnecessary consumers.
Reset the inverter with the front panel switch OFF than ON.
Other failures Check system for correct grounding or contact your dealer.
V/Cell: The nominal voltage using lead acid batteries is 2VDC/Cell. Example: A 12V-Battery contains 6 single
cells, a 24V-Battery contains 12 single cells etc.
45 Maintenance
Only little maintenance is required to keep your inverter and system operating reliable. The inverter must be
switched off during maintenance and/or repair activities. It also must be secured against unexpected and
unintentional switching on. Therefore switch off the connection between batteries and inverter and be sure that
third parties cannot reverse the measures taken.
The following Steps must be undertaken at least once a year. Check cable and wires for damage and if they are
still firmly connected. Defects such as loose connections ore damaged cables etc. must be corrected immediately.
Keep the inverter dry, clean it from dust in order to ensure good heat discharge.
46 Further assistance and sending the unit for repair
In the rare case the unit is not working contact your dealer providing him some details as:
1. Check Battery voltage, wiring and display for possible failures.
2. Note: Type of unit and serial number.
3. Now call your dealer or nearest service center. They will help you with further instructions.
4. If he recommends sending the unit back for repair, use the original packing.
5. Include a copy of the invoice (Warranty repair is only possible with a copy of invoice or certificate showing
date of purchase) and a short notice about your system and the failure observed.
6. In case you have to send the unit over state borders please make sure to fill the correct papers needed for
customs. To reduce time and save money, contact the consignee how to declare the delivery. Arising costs
for customs have to be paid by the sender.
7. Transport costs to send the unit back to RIPEnergy AG are not covered from Warranty.
