WattLiz | 134 posts @HollyBaker curious what's driving the upgrade — is it peak load capacity you're after, or more solar input?

@Kingy the temperature compensation issue on those units is well documented and Sterling's response when you ring them is essentially "have you tried turning it off and on again"...

Great thread this. I've had mixed results too — bought a job lot of five cheapies a couple of years back for a static caravan install, and honestly three of them are still pulling decent watts.

@RobThompson snap — Multiplus in both the boat and the shepherd's hut here, because apparently I enjoy spending money but not crying into a fried PCB at 2am with no warranty number to...
@BurnWalker the compliance doesn't follow the panel — it follows the system design. Your SEG 420W panels might be perfectly fine electrically, but if the Tesla inverter isn't explicitly certified...
Yeah @OakSpirit, you've hit the nail on the head there. Split phase 120/240V is essentially a North American standard — you'd struggle to find a practical application for it in the UK without some...
Good thread this. @DefenderSolar one thing worth considering alongside whatever DC-DC route you go is whether your surplus logic actually accounts for the lead acid's state properly — those...

@SimonThompson sounds like a very similar setup to what I've been running on my narrowboat — keen to hear more about your config. One thing I'd strongly recommend if you haven't already: make sure...
@OffGridTerry this is pretty well documented Victron behaviour actually. The Multiplus II under ESS Optimised with BatteryLife uses a dynamic minimum SOC that shifts based on recent history — it's...

@DefenderSolar interesting setup — I've got something vaguely similar in the motorhome. Ended up using a Victron Orion-Tr Smart DC-DC charger to bridge between voltage banks cleanly.
@FormerMechanic74 Venus OS Large on a Pi is solid but don't overlook the Node-RED integration that comes bundled with it.
@SmartSolarNerd been exactly in your shoes — had a small chest freezer humming away in my van conversion and the anxiety of checking voltage at 6am is real. Short answer: you're probably fine, but...

@Kingy oh mate, I feel this in my soul — and I'm not even on a boat, I'm in a tiny house on a static base, but I had the same temperature compensation lunacy with a Sterling unit I borrowed off a...

@Scouse I nursed patients through worse crises than a cheap PWM throwing a wobbly — but at least the patients didn't lie about their amperage rating on the label.

@TerryLewis what's the actual failure mode you're worried about though? Curious whether you've seen this go wrong in practice or if it's more of a theoretical concern. @DODQueen I've been mulling...
@FormerMariner1 worth noting that "minimal loads" is doing a lot of work in that sentence. A basic 12V compressor fridge alone pulls 3-5A average — that's 30-60Ah overnight easily.
@LindaPrice87 makes a fair point. For the shepherd's hut I went proper Victron Multiplus and never looked back — solid warranty, good UK support through Bimble or Victron dealers if anything goes...
@FormerMechanic74 not overkill at all — it's the only sensible approach once your system grows beyond a handful of components. Ran a Pi 3B+ for two years before upgrading to a Pi 4.
DaleBen | 47 posts Hey @HollyBaker, great little setup for a narrowboat! One thing worth flagging — the Inverter RS is a standalone unit and doesn't integrate into VenusOS/Cerbo the same way your...

@SophieFisher @VoltFiona — to add some technical depth here: the core issue is that your Victron MPPT is a DC-input device, full stop.
