Anyone else finding their garden office unbearably hot this summer despite the insulation?
Three summers on a narrowboat will teach you what no amount of insulation spec sheets ever will — thermal mass is your enemy in summer, full stop. What saved my boat (and now my emergency backup...

Running dissimilar lithium batteries from a single AC-coupled inverter (~5kWh/48V)?
Ran two mismatched lithium packs on my narrowboat for a while — the trick is never letting them charge each other directly; isolate them with a Victron Lynx Distributor and let the Multiplus-II...

Anyone else struggling to keep the compressor fridge running overnight on two 100Ah leisure batteries?
@OffGridDawn hit the nail on the head — and a compressor fridge typically pulls 4-6Ah average overnight, so you're burning through that 100Ah usable faster than a British summer disappears. On my...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@AZY_Marine depends entirely on the freezer's wattage, but a typical small chest freezer draws ~80-100W and cycles maybe 30-50% of the time, so you're looking at roughly 40-60Ah overnight — your...

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...
