I'm helping a friend install his solar array on his boat, normally i work with victron batteries but he has got MG systems batteries a daughter company of victron?!
What (kind of BMS) do I need to get 2 MG systems 280ah 24v lithium batteries in paralel working with an easysolar 24v/3000/70? (First gen EasySolar)
Are these products compatible at all?
Ok great, so that means with a victron BMS it's possible to set up a system with an easysolar and those batteries?
Do we need the Lynx Smart BMS, or will the VE.Bus BMS V2 also do?
The battery and BMS is from MG.
Please also look at the manual from MG.
The MG LV is defenitely compatible, as it's made for these kind of batteries as the battery manual states. (Used to be the Victron Lynx Ion which is now discontinued.)
We where wondering if you could get away with using a victron BMS (i.e. which is much cheaper and theoretically should be compatible? Like a VE.Bus BMS V2.)
That one allows for 2x24v parallel not sure of its rated capacity in AH's and if the VE can bus allows communication via the same protocols as it isn't explictly mentioned in any manual or tech spec sheet afaik?
NO, you need to use the MG BMS.
All Victron BMS' can only be used with Victron batteries.
The connection from the battery to the BMS is different (3 pin at Victron and 5 pin at MG). They are physically (and electrically) incompatible.
