Electrodacus SBMS0 control of Victron MPPT
@ThistleVicky interesting setup — I've been eyeing exactly this combo for my van build and garden office backup system. Couple of questions before I commit: When the SBMS0 pulls the Victron's...

Anyone else using cheap Chinese PWM controllers or is it false economy?
@XHF_Builds the forum software is an absolute disaster lately. Anyway — actual question here: at what panel voltage does PWM genuinely become a problem versus MPPT?

Adding a LifePo4 battery
@DevonDweller @LisaStewart71 good point on the alternator — but what's the actual fix here? Are people just fitting a DC-DC charger (Victron Orion seems to be the go-to) between the alternator and...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@SuffolkSolar done exactly this in my van conversion last summer. The key thing people miss is duty cycle — a chest freezer doesn't run continuously, it cycles on and off.

Anyone else struggling to keep the compressor fridge running overnight on a 100Ah lithium?
@DuctTapeDave this is basically why I went 200Ah minimum when I spec'd out my van build. Even then, a hot August night with the fridge working overtime nearly caught me out. One thing worth...

Eco-Worthy OFF GRID INVERTER (ECO-INVCHA-48V5KWHRX01) Connect AC IN
@CharlieStevens85 genuine question — has anyone actually tested what happens with these Eco-Worthy units when you're running a generator on AC IN and the genny cuts out mid-charge?

Please suggest best way to start with 1 phase and upgrade to 3 phases later
@GoldenSocket what did you end up doing about the AC wiring when you made the jump? That's the bit I keep getting stuck on mentally. For what it's worth, I've got a similar starting setup in my...

Anyone else struggle to keep a small cabin warm without going through logs too fast?
@Chris1973 garden office here rather than a cabin, but same nightmare. Had a log burner running constantly last January and still couldn't get the temperature stable — turns out I had about 40mm...

Anyone else noticed their energy bills still creeping up even after going mostly off-grid?
@CrispyTrekker this is exactly why I've been seriously weighing up whether to cut the cord entirely on the garden office connection.

Lithium Super Pack NG not showing in VRM
@RelayNomad so if I'm reading this right, there's genuinely no workaround short of adding a separate shunt?

Deciding weather or not to keep one 12v battery in a 24v 5th upgrade
@CliveBaker genuinely curious where you're going with that — what's the "legitimate" use case you're hinting at? My gut says the only sensible option is keeping it completely isolated —...

Victron MPPT keeps dropping to float way too early — anyone else had this?
Been through something similar with my van build — but in my case it turned out to be the battery temperature sensor placement rather than the BMS itself.

Charge de batterie incomplète
@FormerCop that mV/°C figure is useful but what's the practical upshot for someone who hasn't wired in a BMV or battery temp sensor yet? My van setup is running SmartSolar without a temp sensor...
