Hoping I can get some help here, I am installing 2 new Multiplus-II in parallel system and all seems to be working well except i get all LED lights as red on the lynx distributor when I have AC power on and the inverters are charging. I have tested all the new fuses just via continuity test and the batteries are getting charged.
The even stranger thing is this: When I put the 120x2 3000 12v 50a Multiplus in standalone operation, they light will be green, then turn red after a period of time, then green again, but as soon as I put them in parallel and they are both charging the batteries from AC power, the led's on the lynx distributor stay red.... I have the battery protect connected to one slot on the lynx, 2 inverters (multiplus-II) each in its own slot, and the final slot is taken up by my BIM to chassis battery/alternator. The batteries are connected to the Lynx shunt via the end posts (where most people would connect the lynx power in). All the components have shutoff switches in between them.
Any help in understanding the Red LED's when under load would be greatly appreciated. As soon as I turn off the load the led's go off, and only the one green in the center of the distributor is lit. The lynx shunt stays green in any scenario.
Update - Even in standalone when the lynx distributor is under load the lights turn red. I have taken everything back apart and verified every connection but no matter what, under load, I get red lights on the lynx distributor. @Guy Stewart (Victron Community Manager) - Either load from chargers or load from the coach, ie when I turn on a microwave and a heater, it happens every time. I have ordered another lynx distributor to see if maybe it is a hardware board fault? I can't think of anything else it would be... Thanks for any advice in advance.
I have raised this with my retailer (CR for multiplus, and another company for the lynx) and they stated they would open a ticket with Victron, but have heard anything. I think this is an odd one, but maybe Victron staff have ran across this before?
