@Paddy cheers for chiming in — yeah the physics absolutely translates across. One thing worth flagging specifically for the 3-phase MultiPlus-II setup though: with DOL starts you're not just...

Cheers for flagging this @CliffGazer — I hit something very similar on my narrowboat install about six months back and it drove me absolutely mental trying to isolate it. One thing worth adding...

@EdGrant91 @MuddyFisher the narrowboat situation is particularly rough because you're often moored under trees or in a cutting with shading from both sides — even on the decent winter days you're...

Hey @BatteryDoug, solid build for the price! For budget LiFePO4 setups around that capacity I've had good results with the Daly 100A Smart BMS — picks up for around £18-22 on AliExpress and has...

Hey @Cleggy51, something worth checking — have you got temperature sensors actually making proper contact with your cells?

EdGrant91 | 312 posts @Nessa the main thing worth watching with mixed wattages is that your controller will essentially track to whatever the lower-performing panels dictate — so if your older...

Hey @Chopper62, had almost identical issues with mine last summer. Worth checking which firmware version the MPPT is running - there were a few dodgy builds around the 1.59-1.61 range that caused...

Hey @LakelandExplorer, the confused labrador feeling is very real! One thing worth checking that nobody's mentioned yet — make sure your MPPT solar chargers are properly associated with the system...

Really good point from @Ollie1981 there on voltage sensing — that's often the culprit that gets overlooked. I'd also suggest checking your tail current setting if you're on lithium.
