Some people may remember I posted a few days ago about our battery issues. We’re seriously looking at changing to lithium batteries but having real problems in deciding exactly which way to go. We’ve got a Victron solar controller and solar panels and I’ve been impressed with the quality of Victron kit. The obvious and easy answer is just the obvious answer is just to buy all Victron kit. However, Victron batteries are the thick end of $2000 each and they don’t even come with an inbuilt BMS. You have to buy a Victron BMS separately plus various other components.
I’m planning on buying one or two 300 aH Lithium FePo4 batteries with built in BMS. I then need a DC-DC charger plus an IP34 mains charger for when we’re connected to shore power or running the generator. All good do far.
It’s the monitoring I’m confused about. A Cerbo GX plus a touch screen display looks good but one company is then trying to add Lynx shunts and distribution and power in modules plus a battery protect module.
I thought most quality lithium batteries had built in battery protection? Also the Lynx stuff is completely OTT for our purposes and very big. We only have 30 amps max from our panels and a max of 50 amps from either the mains charger or the DC - DC charger.
However without the Lynx bits how do I still monitor things?
