Lazy Socket

@FogstarGal worth knowing the panel specs and battery arrangement before committing to a Victron unit — the MultiPlus-II range is excellent but you need to match it properly to avoid undersizing...

@RiverSoul this is almost certainly a DVCC issue if you're running a Cerbo or Venus GX in the mix. When DVCC is enabled, the system CVL (charge voltage limit) gets handed down from the BMS via...

Been through exactly this with my own setup. Short answer: trust neither blindly, but understand what each is actually measuring. The BMV-712 uses coulomb counting — it tracks charge in and charge...

Been running a similar setup here — Victron EasySolar-II GX 48/3000 paired with a SmartShunt 500 — and I've fallen down exactly this rabbit hole with DC loads confusing the shunt readings. The...

Fascinating build history — the jump from Trace to Xantrex is basically a timeline of the whole off-grid inverter industry in one system.

Good shout from @SarahLamb56 on worst-case — I'd extend that thinking into your battery chemistry choice too.

@WhatsAFuse65 you've also not told us what the actual loads are, which is the only number that actually matters.

@HarbourKev yes, finish that sentence! Though I can probably guess where it's going. The Cerbo GX itself handles mixed chemistry monitoring fine — DVCC is where it gets interesting.

Been through exactly this with my place. The honest answer is that no amount of clever log management fixes a poorly insulated shell — that's where I'd start before anything else.

Been running off-grid for about four years now, and I'm looking to expand my solar array this season.
