Dear Community,
my inverter is placed in Rwanda, working since 3 years without any problems.
The inverter was most used as a pure voltage supply, somtimes as standby voltage supply and also in charge only mode. The average permanent load was about 500W. The airtemperature in the technic room is between 20 and 25°C (day and night). The public grid is not very stable: voltage and frequency has bad performance.
Last week low temperature LED goes on, inverter stopped working, we checked the batteries but they where fully charged (we measured the open circuit voltage and voltage under load); we disconnected all cables as a kind of HW reset, we reconnected all cables and the inverter was starting again in status inverter ON. After 4 to 5 hours the temperature LED comes to ON and inverter stopped working. Until now we tried some cases to restart, but it is not working anymore.
Who can support or had a similar problem.
Thank you
Erwin
