I have a Victron Multi 3000 for 12V- 120A charger
- 120V (US version) with remote control panel
. When I installed it it would not provide much power. Over about 1000w it would quickly go into over temperature. A Victron service
person in Palma found that the fan connector had come off the circuit board. Can happen with shipping
it around the world.
The Multi then worked fine. I re-programmed it - using the DIP switches - to default to 50 Hz. I have a mixed 120V and 220V boat system with a Victron Auto transformer. I needed 50 Hz as my European washing
pump did not like 60 Hz. The programming worked fine with all the lights doing the right things.
2 months later I discover that the default setting for the charger
is set to 75% of its rated amps. So instead of providing up to 120A charge it stops at 90A. My bank is 840Ah lead-acid and can absorb more. On occasion I have used also the standard Cristec chargers on my boat in parallel and saw over 150A absorbed.
When I went through the DIP switch programming again, it started out strange. As I set the switches, without doing anything else, the LEDs would come on and go food
in random order. When I then switched the UP button to set the new charge parameters nothing happened. I.e the appropriate LEDs did not come on. I tried this several times.
I then had the Victron guy in Palma try it and it did the same thing. Next day he came with the VE-config software
and the PC adaptor (actually 2 slightly different ones). He tried programming using the VE-config software
but it never made a connection to the Multi. Even tried it with my laptop
and another network cable.
After this whole process the charger stopped working altogether.
So now I have a Multi that is 8 months old, that does not charge and will not drive my washing
Victron thinks the circuit board needs replacing, but it is not made anymore. Now they offer me to sell me a new Multi at a 'special' price
Any idea what I could try to make this Multi work again?
