SueThompson99 | 156 posts @ROW_OffGrid I ran mine at 14.2V absorption for about six months and was perfectly happy, but recently dropped it to 14.0V after reading some discussion about cycle...

@BrookRunner the flat voltage curve issue @ExBrickie mentions is real, but I'd also check your charged voltage and tail current settings in the BMV.

@EwanGreen we're all waiting for that cliffhanger to resolve 😄 But yes, the struggle is real. On my narrowboat I've got a similar Victron MPPT setup and in proper thick overcast — the kind of flat...

@ShortCircuit56 short answer — not reliably, no. Did exactly this on my static last November with a Fogstar 100Ah and a cheap 2kW inverter.

LeeParker | 247 posts @UWW_Power nice setup for the price! I'm running something similar — three 180W Renogy panels (picked up refurbished) into a SmartSolar 75/15, and honestly the Victron side...

Davo2 | 847 posts @DorsetSolar completely agree on the cable losses front - the physics just don't lie once you're pushing serious current.

Good thread this. @12VNerd I'm running almost the exact same setup in my camper — DCC40S plus a Victron MPPT feeding a 200Ah lithium bank.

Squib82 replied: Worth adding one thing nobody's mentioned yet — if your Cerbo is off-grid without a consistent internet connection (as mine is on the boat), NTP sync won't always save you...

@LochChild great project! One thing worth flagging that often catches people out — factor in your worst-case days, not average sunshine.

MidlandsNomad | 634 posts | Array Worth adding — the Voc of that 175W panel is the bit that'll catch you out.

Running a Multiplus-II 24/3000 on my boat and a separate 48/5000 in the garden office, so I've got both to compare. Curious whether anyone's noticed idle draw creeping up in colder months?

Hey @MarshLover, to add to what others are saying — have you looked at your actual irradiance figures for your location?

@Rodney3 worth checking your battery BMS isn't quietly pulling the plug on proceedings — mine on the narrowboat did exactly this under kettle-plus-microwave combos until I realised the Fogstar...

Jock40 | 847 posts | ⭐ Trusted Member Tilt angle matters a lot more in winter than summer, @SparkyHiker.

Picked up a 200Ah Fogstar Drift last spring and it's been brilliant all summer. Now temps are dropping I'm getting the low-temp cutoff kicking in around 4–5°C, usually early morning before the...

Hey @MidlandsNomad, solid choice on the Drift — cracking battery for the money. I'd lean Orion-Tr Smart personally.

I picked up a 100A shunt monitor off Amazon for about £12 to track my 100Ah LiFePO4 leisure battery in the van.

@BoxerWanderer one thing worth considering before deciding is whether you'll ever want to sell either structure independently. Keeping separate systems preserves that flexibility.

AlanWilson | 634 posts | Yorkshire @Scouse Worth checking your Isc figures carefully before committing. The MPPT doesn't care much about wattage mismatches — it's current and voltage that matter.
