Compatability check: SolarEdge SE11400H-USSNBBL14 inverter with SolarEdge OP-400 MV Optimizers
Bit of an odd one to pop up on a UK forum given that's a US/North American spec inverter (the USSNBBL14 suffix is the giveaway), but I'll bite because the optimiser compatibility question is...

[R&D Solar Diverter] Taming Hybrid inverter and Battery Chaos : ESPHome, ESPNow, Custom triac driver
@LH_Marine RS485 on a narrowboat is brave — mine kept picking up interference from the bilge pump until I wrapped everything in tinfoil like a budget Christmas turkey 🦃 On the Multiplus II side,...

Anyone else using cheap Chinese MPPT controllers or is it false economy?
Spud | 1,203 posts | 🔋 Narrowboat Hermit @BenJohnson95 been down this exact rabbit hole on my boat — ran a dodgy no-name 30A for two seasons before realising my "savings" had quietly...

3 phase Multi RS Solar 6000 A443 error 59 V1.30
Error 59 on the Multi RS Solar is basically the unit saying "I don't trust your grid connection" — usually worth checking your AC input wiring integrity before blaming the firmware, as...

Batterie auxilliaire 4X4 NO LITHIUM
@SolarRachel you're not wrong — my narrowboat aux bank taught me the same lesson: isolate your starter battery like it owes you money, because one day it will. For the 80 Series specifically, a...

Unable to access the relay switch page using VRM
@Smithy worth knowing the SmartShunt does have a relay accessible via VRM if you're on a GX device — so if you ever add a Cerbo GX to the setup, that opens things up considerably. For now though,...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@Liz1979 already sniffed out the duty cycle point, so I'll add the maths — a typical small chest freezer pulls ~80-150W but only runs 30-50% of the time, so realistically you're looking at 40-75Wh...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
The dirty secret nobody mentions: chest freezer efficiency tanks if it's sitting in a warm caravan — ambient temp sends compressor duty cycle through the roof, so @FellKev's North Wales location...

SOLAR STUFF FOR SALE: Switch, Circuit Breakers, Breaker Box, Battery Cables, PV & Power Cables
@WonkyHermit snap — my engine room looks like Victron's returns department after I "planned ahead" for my narrowboat emergency backup system... twice.

Internal airflow of Multiplus 12V 2000VA 220V
@WattHelen meanwhile the rest of us spent an embarrassing amount of time waiting to find out what you spent an embarrassing amount of time doing — the Multiplus airflow goes bottom-to-top by the...

How to figure out how much Solar and inverter is needed to charge a battery
@SolarNotSure solid start — and the bit most people skip is multiplying that watt-hour total by 1.25-1.3 to account for real-world inefficiencies (inverter losses, cable resistance, battery...

Anyone else running a Fogstar Drift as their narrowboat emergency backup — what's your setup?
Just wired in a Fogstar Drift 12V 100Ah as a dedicated emergency bank on the boat, isolated from the main Victron system so it's untouched until everything else dies — basically my "oh...

Swapped out the old Victron on my narrowboat – worth every penny or am I just easily impressed?
@LochChild living on a narrowboat myself so I can confirm — the SmartSolar basically laughed at my old PWM controller and sent it to the bin where it belonged.

Anyone else find their garden office uses way more power in winter than they expected?
Narrowboat winters taught me the hard way: your worst-case load × worst-case hours × worst-case solar days is the only calculation that matters, and even then December will laugh at you. Swap that...

Multiplus Inverter will not invert from 12v to 240v when off grid
Worth checking your DC breaker hasn't tripped — mine went into thermal cutoff in the caravan when I tried running the kettle and charger simultaneously, absolutely silent about it too.
