Hello, I have a 1120Ah LiFePO4 12V battery being charged by a MultiPlus-12V 3000VA 230V.
I have connected the Multiplus in-line of the feed to the 240V AC distribution panel and using the feed through facility to run the 1KW immersion and some other small domestic loads.
I also have a 4KW generator for when the "shore supply" isn't available, when the shore supply is connected the Multiplus will charge the battery fine and will also heat the hot water.
However running the generator is a different story, when I do so the Multiplus will pass through the 1KW heating load and if I turn the charging on the Multiplus will start charging, if I turn the charging up every now and again the charging stops, the Multiplus switches over to inverting and the heating load is now being picked up by the inverter and the batteries, after a minute or so the Multiplus switches back to pass through the heating load (onto the generator) and starts ramping up the charging again, it will then run sometimes for a while or sometimes more or less straight away it will trip again.
I am pulling around 3Kw which I would of thought the 4Kw generator should be able to cope with without too much of an issue.
I have set the current input limit to 16A, changed the setting in the input from "shore power" to "generator" and that may have stopped it tripping as much, but not completely.
If I cut the charger back in the DVCC it helps as does turning the immersion heater off, but the whole point of running the generator is to load it up, as this is the best for them.
HELP anyone with any ideas???
