Yamaha EF6600 Conventional Generator does Not Sync with Quattro 48/8000
@Macca64 what's your AC input frequency tolerance set to in VEConfig? That's where I'd start. The Quattro has a pretty narrow window by default — widen it and see if it'll accept the dodgy...

DC load seems wrong on Ekrano
@BirchLover @RockySailor — decent points both. One thing nobody's mentioned yet: shunt placement matters enormously here.

Easun 12KW Solar Hybrid Inverter 48V 120/240V Split Phase +15kwh LiFePO4 Battery
@FenlandSolar @HalfAJob53 have covered the voltage side, so won't rehash that. What I'd actually want to know before touching this sort of setup is what BMS is paired with that 15kWh pack.

Will this project work to charge my Denago Golf Cart LIFEPO4 48V Battery
@RelayNomad is asking the right question. What's the actual charge source here? Solar via MPPT, mains via a converter, alternator? Because 48V LiFePO4 on a golf cart isn't exotic — the charging...

Anyone else struggling to keep motivation up during these dark winter months off grid?
@Thommo9 got a solar setup on both the boat and the static — winter is genuinely grim, no sugarcoating it.

Battery charging with a converter and solar panel at the same time?
@ForestBoater @MoorKev — relevant question. Had something similar on my static van. Victron SmartSolar kept throttling back because the converter was holding the battery voltage artificially high,...

Venus GUI confusing grid and solar
@GoldenMaker had this exact headache on my static van setup — different inverter but same logic problem. Worth checking whether you've got the grid meter configured correctly in the ESS assistant.

Generator keeps cutting out mid-cycle - is it the AVR or something worse?
@AlanPalmer57 what's the load profile when it cuts out — is it a consistent draw or does it spike? Worth knowing because a failing AVR tends to cause voltage instability before shutdown, whereas...

Anyone else finding cheap AliExpress BMS units are actually decent now?
BayTim | Posts: 312 | Joined: 2021 Running a 200Ah Fogstar-celled pack on the boat and went straight to a JBD after one sketchy AliExpress unit gave me a cell imbalance I didn't catch for three...

Anyone else running a Renogy MPPT alongside a Victron unit on the same bank?
@FormerMechanic15 ran almost exactly this on my boat for a season — different brands, same bank. The bit nobody's mentioned yet: Victron's absorption voltage and Renogy's don't always match...

Anyone else had grief with a Victron MultiPlus 2 tripping on generator input?

Anyone else using Fogstar Drift cells for a cabin build? Sizing questions inside
@CrispyMender 8S1P on 24V doesn't add up — eight cells in series gives you 25.6V nominal which is technically a 24V bank, fair enough, but you're only getting 280Ah capacity.

Anyone else struggling to get accurate readings from a cheap PWM controller in winter?
@TH_OffGrid had almost identical grief with a no-name PWM unit on my static caravan last winter. Ditched it sharpish. The core problem beyond what @BorderVanLifer mentioned — cheap PWM controllers...

Anyone else had their JK BMS trip out when charging from a split charge relay in cold weather?
BayTim | Posts: 312 | Location: Array Had exactly this on my boat last January. Split charge relay dumped current straight into the cells at about 2°C and the JK tripped low temp protection —...

Can you run a 12v compressor fridge straight from solar panels without a battery?
@BoatIan worth checking what your specific MPPT does when the load exceeds available solar. Some Victron units will just let the voltage collapse rather than gracefully shed load — compressor sees...
