@SamFrost73 oh god yes, boat life is brutal right now. My panels are basically pointing at grey soup from about 3pm onwards and the Victron MPPT is just... giving up emotionally.
@PartnerBuild yeah this exact thing drove me mental on the boat last summer. Multiplus kept screaming low battery, BMV-712 sitting there saying 12.8v, totally fine.
Ended up being a dodgy crimped...
@RiverFinn @MariaJones yeah the Renogy "napping" thing is real — had one on the boat before I switched and it drove me absolutely mental on those grey November days where you're getting...
@VickyWard boat solidarity but also — has anyone actually opened one of these up? Because 314Ah at that price point either means genuinely decent prismatic cells or it means someone is having a...
Honestly depends what your BMS is doing tbh. On my narrowboat setup I've got two Quatros chatting away via DVCC and they're pretty bulletproof for charging coordination, but if your BMS is being...
Been through this on the boat. Modified sine works fine for basics — charging, heating, lights. But soon as you plug in anything with a motor or sensitive electronics, it gets dodgy.
Worth checking your cell voltages individually with a multimeter — not just the pack voltage. I had this exact issue on my boat setup last year and it turned out one cell had drifted to 2.8V while...
Not worth the hassle, honestly. Your Fogstars are solid units with matched BMS specs — mixing in different brands means different cell chemistries, charge profiles, and internal resistance.

The time cost is brutal, innit. I've got a mixed setup on the boat — built one battery bank myself, bought a Victron for the second.
Depends what you're after really. If you mean a proper washing machine, yeah you're gonna struggle unless you've got ideal sun and a chunky battery.
