Perfect. I wondered but so helpful to have your input.

Thanks. I guess I was worried about the disconnect voltage at 16v...perhaps I don’t understand what this means. Alternator was running for 10 mins but this has run fine for years. The mains goes through a Sargent ECB which converts to a DC current. Sounds like they are all doing the same?

So I’ve managed to connect my array (thanks Mike) and now I want to check the settings are right...they seem a bit high. Picture below of how they are set by the manufacturer (sealed battery) My 12v battery is fully charged at 13.8v and with the alternator running it says 14.4v and with the top...

Cheers Mike, yeah it’s a VW T5 so batteries can be replaced but they are in cages under the van and therefore cables need to go through the floor. So are you saying I can just take a ‘spur’ like I suggested off the leisure cables. It will top up the leisure batt and the Sargent will still get...

Hi Mike, thanks for the advice. There is a combining relay in the unit. Not sure what the nagres relay is for. The issue I have with the camper is that accessing the battery through the floor is very difficult. What would be the issue of using the load? Also could I run it like a spur? I.e in...

By the way. The Sargent ECB is an older model with no dedicated Solar input so it will be entering via the standard input

Thanks current set up Proposed set up

Thank you. So whether the supply comes from the ‘load’ or the ‘solar’ is irrelevant. As long as voltage is not exceeded.

Thank you. I think this won’t be an issue. The whole setup is 12v and the controller is 20A which is the maximum fuse in the ecb. My question is really about what if power is coming the opposite direction ie. from the ecb to the load terminals on the MPPT controller and out to the batteries...

Ok so... I have a epever MPPT controller and a Sargent Campervan ECB. My question is...if I connect the controller between the batteries and the controller what happens when I am plugged in at a campsite or when the alternator is producing power? Will it flow in reverse back through the controller?
