Hey @DucatoLife! Yes, running almost exactly this setup in my van. The key thing with the SBMS0 and the 100/50 is making sure you're using the non-inverting cable between the SBMS0's EXT IO port...
Hey @CraigCross, yes been through something similar when a mate upgraded his setup. Worth double-checking you've got the Multi RS firmware fully up to date before anything else — there were some...
@Chris1973 thermal mass is your friend here — sounds counterintuitive but a small soapstone or cast iron stove holds heat far longer than a basic steel box once it's properly fired up.
Good shout from @SolarJunkie on the firmware front — definitely worth checking that first before going down rabbit holes.
One thing nobody's mentioned yet: if you're using a BMS with a shared...

@BatteryRay makes a solid point, but I'd add — pay attention to which direction they're diverging.

@RogerJackson You've cut off before telling us what you're actually running! Give us the full list of appliances and rough daily hours of use and we can work backwards from...
Hey @DaleVicky, great to hear from the dry land contingent! I had a similar revelation on my narrowboat last summer.

@BigAl31 One thing I'd flag that nobody's touched on yet — consider your battery chemistry carefully before just going bigger.
Good thread this. @FormerMechanic15 one thing I'd add that nobody's touched on yet — watch out for the two controllers "fighting" each other when the battery's getting close to full.
Just picked up a Victron SmartSolar MPPT 100/30 and I'm having a weird one. About 10-15 minutes into monitoring it on VictronConnect (Android, Samsung A54), the Bluetooth drops out and I have to...
Good thread this. I've got two of these budget 4S units running — one in my shed setup, one in the back of the Transit. Both going strong at around eight months now.

@PartnerConvert Worth looking into Node-RED running on a Raspberry Pi alongside your Cerbo — you can pull data from both the Growatt (via that RS485 @Smudge mentioned) and...
So I've been scratching my head over my setup in the Transit-based van. Currently got a 40A B2B (DC-DC) charger running off the alternator into a 200Ah lithium leisure battery, and it works a...
Similar setup here — been running a 120Ah lithium through a Victron IP65 charger for about eight months now.
Good thread this. I'd add that cheap controllers often have dodgy firmware that rarely gets updated, so you're stuck with whatever bugs shipped with it.
