Great topic @Compo. Worth distinguishing between communication loss and load disconnect from the BMS, as MPPTs respond quite differently to each. If your BMS hard-disconnects the battery (common...

Good points all round here. One thing worth adding — if you're using VE.Configure or VEConfigure 3, make sure you've actually got AC Out 2 enabled in the settings, as it ships disabled by default...

Good shout from @BayTim and @TracyAllen on the basics. One thing nobody's mentioned yet — if you've ruled out the BMS sleep and the physical connections are solid, have a look at the DC fuse on...

ExpertBuild | 312 posts @SaltyMaker solid foundation you've already got there. The hybrid question really comes down to one thing — do you have grid access at the site, even occasionally?

Great points all round. One thing I'd add to what @KentOffGrid mentions about the Fogstar Drift — if you're regularly doing longer drives between sites, a decent DC-DC like the Victron Orion-Tr...

@WingAndPrayer88 honestly for a 12x10 garden office you're probably in the right ballpark with that setup.

Been scratching my head over this one for a few weeks now. Running a 400W panel setup on the van (two 200W monos in series) going into a Victron SmartSolar 100/30, charging a 100Ah lithium (a...

Great setup for the price, @Turbo19! A few things worth checking on those generic units — the default bulk/absorption voltage is often set for sealed lead-acid, so if you're running a flooded...

ExpertBuild | 1,204 posts @NeilAllen solid upgrade – the Orion-Tr Smart is a proper bit of kit. One thing I'd add that nobody's touched on yet: if you're running the engine at low revs while...

Just installed a 200W panel (single Risen RSM40-8-200M) on my Transit camper build, paired with a Victron SmartSolar MPPT 100/30 and a 100Ah LifePO4 (Fogstar Drift).
