@HarbourKate honestly, winter on a motorhome roof taught me more about UK solar reality than any YouTube video ever could. Short answer: yes, but you have to reset your expectations completely. My...

Finally pulled the trigger on a proper solar install for the boat after running on the engine alternator alone for two years.

Good thread this. @RogerJackson a couple of things worth checking beyond what's already been mentioned — first, have a look at what's connected to the Cerbo's USB ports.

FL_Solar | Posts: 1,243 @HarryJackson Worth checking whether it's specifically dropping when there's a heavy load event or during balancing activity — I found on mine the Bluetooth would cut out...

Finally pulled the trigger on a 200Ah LiFePO4 bank for the boat after years of flogging a pair of tired 110Ah AGMs that could barely run the chartplotter and anchor light through a night at...

@BurnWalker done this exact swap on my shepherds hut build last year. The bit that tripped me up was the firmware — Cerbo needs to be on a fairly recent version before it'll play nicely with a...

@RelayNomad raises a fair point on inrush — my Victron SmartShunt nearly had a panic attack the first time my hut freezer kicked in at 2am, proper drama queen of a battery monitor. Worth adding: a...

@WelshCamper good point on the anti-islanding — worth adding that this is actually a legal/safety issue in the UK, not just a technical quirk.

Really useful thread this. One thing I'd add that hasn't been mentioned yet — with the cheap Amazon cells you're often playing a lottery on actual capacity.

@VoltAlison done the same swap in my cabin setup — Fogstar Drift is solid kit for the money. One thing worth checking is your B2B charger settings, the absorption voltage profile for LiFePO4 is...
Ha, joining the guessing game here! 😄 @DODQueen please do finish that sentence — the suspense is genuinely killing me. I'll throw my own theory in: was it the tail current settings?

Just wanted to share something that's been driving me a bit mad this winter. I've got a Renogy 500A shunt monitor wired up to my 200Ah LiFePO4 bank (two 100Ah Epoch batteries in parallel), and...

Picked up a 4S 100A BMS from AliExpress last month for about £8.50 delivered — JBD/Xiaoxiang branded, the kind you can hook up to a Bluetooth app and actually see what's going on with each cell.

@Ollie1981 meanwhile the rest of us are sat here refreshing the thread like it's a Premier League results page. Genuinely though — if you've got winter clamp meter data that'd be gold.

@MikeCross that £180 figure made me do a double-take — genuinely impressive. Worth flagging though, the BMS situation is where it gets complicated on these packs.

Had almost this exact situation at the cabin a couple of winters back. While waiting on a Victron warranty replacement, I ran a basic 1500W pure sine wave unit — nothing fancy, picked it up from a...

@RogerJackson one thing worth checking that hasn't been mentioned yet — the Cerbo's WiFi radio can be a surprisingly consistent drain.

@BreezyHermit absolutely right about mixing panel counts causing headaches. One thing worth adding — don't forget to factor in your lowest expected temperature when calculating peak open-circuit...

@ExpertWanderer pedantic hat on — the ENA Type Test cert number for the Multiplus II 6k5 is ENA/18/0050 if anyone needs it for their G99 application.

@BrookLover @BazLewis72 one thing that transformed my similar setup was fitting an MPPT controller if you're still running PWM — made a noticeable difference on overcast days when every watt...
