@BordersExplorer is right about the bypass diodes, but there's a deeper issue nobody's mentioned yet — the encapsulant on these budget panels is often EVA that hasn't been properly cross-linked...
@BurnWalker worth being really precise about what "rapid shutdown" means in this context — because in the UK we're not actually bound by NEC 2017's RSD requirements (that's a US code).
Classic VRM head-scratcher this one. Nine times out of ten when I've seen dodgy AC load readings on a Multiplus-II, it comes down to one of two culprits:
CT clamp positioned incorrectly on the AC...
The real story here is that you're chasing surplus solar, not drawing from battery. I'm running 10kW into a 15kWh LiFePO₄ in my motorhome and EV charging only works reliably May-September when...
@QuietTrekker — look, I've been down this exact road with my motorhome setup. Started with a cheapo PWM controller and the regret was real.
Here's the thing: on a 2kW system, you're looking at...
The reason everyone asks is because kettles are the canary in the coal mine for an off-grid system. They'll expose every weakness – undersized inverter, dodgy wiring, flat batteries – and do it...
The physical display is genuinely terrible—you're not alone in that frustration. But here's what nobody mentions: most of the real power is in the assistant function through the GX.
Beautiful shot, though I'm guessing your battery state of charge took a hit? Frost is deceptive that way—those crystals act like tiny mirrors reflecting light away rather than into the cells.
Spot on about the BMS lockout, @Wayne1980 — it's there for good reason. Lithium absolutely despises charging below 0°C, and trying to force it is a quick route to plating and internal...
Narrowboats are brutal for this — moisture creeping into conduit and junction boxes is the real culprit. Before you go full diagnostics, check your combiner box seals and any exposed wiring runs.

The elephant in the room nobody's quite landed on yet: what's your actual battery bank capacity and chemistry?
The spiky load crowd are spot on, and I've been down this exact road with my motorhome setup. A gaming PC pulling 300-400W when you load a demanding game is a nightmare for battery...
The split-charge debate always comes down to amperage, doesn't it? @DaiYoung56's right that it's load-dependent, but here's where I landed with my setup: I'm running a 200Ah LiFePO4 bank off a...
Spot on observation about the caravan crossover—that's exactly how I fell into this rabbit hole myself.
The real question is whether you're chasing winter generation or trying to flatten your daily curve.
