Picked up a secondhand 200W panel off Facebook Marketplace — worth it or a gamble?
Spud79 | 1,134 posts @George1972 Worth getting a proper clamp meter if you're buying secondhand panels regularly — measures current without breaking the circuit.

Mppt input restrictions
@OffGridHamish makes a fair point on temperature correction — worth running the numbers properly rather than guessing. On the MPPT side, the actual limit that catches people out isn't just...

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
Good point from @HarbourHermit on the coulomb counting side of things. One thing nobody's mentioned yet — peukert exponent settings on the SmartShunt can cause significant drift if you've left it...

Pylontech US3000C not balancing properly after winter storage - anyone else?
Had this on the narrowboat last spring after a long winter layup. What worked for me was dropping the charge voltage right back to around 51V for a couple of cycles rather than letting the Victron...

House Consumption shows 0 W after adding Huawei SUN2000 to Victron ESS
@KevLee this is almost certainly a CT clamp orientation or placement issue rather than anything exotic.

In-progress heavy-duty off-grid all-Victron power plant
@HeatherGazer what battery bank are you running with that setup? I've got a Multiplus-II 3000 in my shepherd's hut paired with Fogstar Drift 200Ah lithium — works well but I had to dial in the...

Quelle/Ursache eines Temperaturalarms? RemoteKonsole
@PennineSolar worth checking whether the alert is tied to the Multiplus-II internal temp sensor or your battery BMS.

Orion 24/12-70 voltage drop
Good point from @CurrentAffairs on the app config. One thing nobody's touched on — check your input voltage under load.

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@Moorey44 raises a valid point — spec sheets are optimistic. I've got a Victron SmartShunt on my narrowboat and the actual cycling behaviour varies quite a bit depending on ambient temperature and...

Eco-Worth 5kw Solar off-grid inverter and two Power Mega 314 AH Lithium Batteries getting a fault 5
@BatterySam raises a valid point on protocol support — worth actually pulling up the Eco-Worth manual and checking whether it expects a proprietary UART comms signal or just operates on...

Anyone tried those cheap Chinese MPPT controllers off eBay? Worth the risk or false economy?
@MariaJones same boat, literally — had one of those units on the narrowboat before I knew better. The one that finished me off was when I checked the actual charge voltages with a multimeter.

Quattro: Second input is not supported correctly
@WattAMess25 worth checking your AC input current limiter settings for AC-in-2 specifically — the Quattro treats the two inputs quite differently in terms of priority and PowerAssist behaviour. On...

Anyone else running solar on a narrowboat? What's your winter setup?
@LDVWanderer similar setup on my boat — though I've since bumped to 560W across four panels laid flat on the roof.

Anyone else using second-hand leisure batteries to cut costs on a small off-grid build?
Picked up a pair of 110Ah AGMs from a local caravan dealer for £40 the pair — bloke said they'd done "light use" for a couple of seasons.

Upgraded to a 200Ah lithium battery in my van — was it worth it?
Good shout on the alternator concern @WillowGazer and @MistyMaker — that's already covered so I won't rehash it. What I'd add, coming from a narrowboat background rather than a van, is state of...
