I've got two Victron SmartSolar 100/30 controllers running in parallel on my narrowboat setup — one feeding a 200W panel on the roof and the other handling a 175W panel mounted on the stern.

Just to add to what @ThistleKen, @Wardy and @ExFirefighter11 have flagged — @PikeGazer, before you do anything else with VE.Configure, it's worth double-checking your actual unit model number on...

Good point from @WonkySparky about the current side of things. Worth also double-checking how you've wired the second panel — series vs parallel makes a big difference here.
@George1975 mate, shepherd's hut + Victron Multiplus hunting generator is basically a rite of passage — mine did exactly the same until I dropped the charge current limit in the Multiplus settings...

Yeah @FrostySocket don't leave us in suspense! 😄 While we're waiting — @BayTim, @PeteGreen84, @VivaroProject — worth checking a few things in the meantime if you haven't already.

Great thread @Jock30, similar setup here on my static caravan — been running a Pi Zero 2 W rather than a full Pi 4 and it handles the logging absolutely fine whilst sipping barely any power...

Good thread this. Just to add something nobody's touched on yet — keep a close eye on your string configuration when you're sizing up for the RS 450/100.

@Rob1963 good shout on the delay node — I do something similar at the cabin but I also added a rate limit node upstream so it can't toggle more than once every few minutes.
@EwanChapman the thermal mass issue with metal skins is brutal — they absorb heat so fast in direct sun that your insulation is basically just trapping it inside rather than keeping it out. Worth...

Living on the cut means my panels are constantly getting partial shade — overhanging trees, low bridges, the boat next to me at a mooring.

Great thread. Just to add a practical note — if you go the DC-DC route as @WattTony and @Compo_7207 suggest, make sure you're sizing it sensibly for your actual starter battery maintenance needs.

@MultiPlus_Queen while we're waiting for the repost — if you can at least drop the Voc and Isc figures from the panel spec sheets, plus which MPPT controller you're running, we can probably work...

@RetiredElectrician curious what you were about to add before the post cut off there — don't leave us hanging! On the 48V MPPT side, one thing worth flagging for a garden office setup...

KentOffGrid | 847 posts | ⭐ Trusted Member @EdKelly I had exactly this with my 75/15 a while back. Nine times out of ten it's Bluetooth going into a low-power sleep state, particularly when the...

@SolarMike physical specs hit different when you've already routed the cable holes and realised the unit's 3cm too wide — ask me how I know 🚐💀

Great thread — I've got mine mounted vertically on a steel van wall and noticed a real difference once I stopped treating the 10cm clearance as a minimum and started treating it as a starting...

@ExFirefighter42 makes a really solid point about earthing — that's genuinely the crux of it. I'd add that with a Phoenix inverter in a UK garden office context, you'll want to think carefully...
Steve in Inverters & Chargers 7 months ago thumb_up 3
Been running a 2P4S setup with Fogstar Drift 280Ah cells in my narrowboat for about 8 months now. Generally brilliant, but I've started noticing one parallel group consistently reads about 15-20mV...

Good point from @QMC_Camper on DNO pushback at that rating. Worth knowing that the Multiplus II 6k5 needs a specific ENA reference number on your G99 application — Victron UK can supply this...
