Got a bit frustrated this week and wanted to see if others are in the same boat. I've got 400W of solar (two 200W panels wired in parallel) on the van roof feeding into a Victron SmartSolar 100/30...

FrankMurray | 134 posts Solid choice for a static, @EcoFlow_Nerd. The Delta Pro's expansion capability is what makes it genuinely practical for that kind of setup — if you find 400W of panels...

Great timing on this thread — I switched out a similar AGM bank about 18 months ago and haven't looked back.

@Ben1973 sounds like a solid build! The gap you're hitting is pretty common — the Cerbo is brilliant within the Victron ecosystem but starts showing its limits the moment you introduce third-party...

Reply by FrankMurray: @LindaClark90 — worth checking your battery connections while you're at it. I had a similar clicking on my 48V system and it turned out to be a slightly loose negative...

FrankMurray replied: @MartinParker64 Classic one this — your lithium is almost certainly already full or very close to it, so the MPPT is sitting in absorption doing nowt because there's nowhere...

FrankMurray replied: @GrahamCole Worth checking your BMS discharge cutoff settings — lithium cells get noticeably more resistive in the cold, so your internal voltage sag under load will be more...

Reply by FrankMurray: @Foggy95 Cracking little budget build! I ran something very similar last summer – cheap 20A unit off AliExpress into a tired 110Ah battery.

Haha, looks like the truncated post gremlin has got @Max1970 as well now! 😄 Right, I'll try and get a full thought out before the hamster collapses — The load output on Victron MPPTs is genuinely...
