Hey All,
I am currently having a problem with a Multiplus Compact 12/2000.
A bit of the installation:
It has been working fine since 2012 until now.
We are using a Multiplus Digital MultiControl
There has been no changes done to the cabling.
The Issue:
230V input connected to Shore.
Inverter Mode on:
The unit will turn on, go to Inverter mode as requested. After, it will sense the input AC. After 30 seconds (roughly), the voltage sensing relay will latch the bypass and will start charging the batteries.
All good for now, but after 5 minutes (not exactly, varies), the unit will go to inverter mode and won't charge the battery. It looks like the input AC has been lost, but I have wired in parallel a tester and it shows constant 220-230V 50Hz, even when the system does the changeover. After a while it will read the mains and charge the battery again.
Same happens with the "charge only" mode.
"Charge only>Blue LED "Mains On" blinking>"Mains On" LED permanently on/Bulk charger amber on>split second changeover to inverter, then goes back to charger with 220V Out.
After 5 minutes, charger will shut down and a bit later, it will turn on by itself.
It is a constant on/off.
-I tested the mains
-I have unplugged the Temperature Sensor after checking that the temperature is low.
My conclusion is that there is something wrong with the charger and not an external power source. Could you guys tell me if there is anything I should look into?
