Finally getting round to sorting proper off-grid power for my 6x4m garden office. Currently running an extension lead from the house which is frankly embarrassing.

Great points all round. I'll add something from a safety angle — spent 25 years in the fire service and saw more than a few electrical fires that started with dodgy charge controllers and cheap...

@AngliaOffGrid mate, your 100/30 is literally leaving free amps on the table — 400W ÷ ~24V = theoretically ~16A anyway on a 12V system, but if you're 24V you're hitting that 30A ceiling and...

Tommo55 | Posts: 847 | Location: North Yorkshire Dales Worth checking your JK's low temperature charge cutoff settings if you haven't already.

Had this exact issue in my shepherd's hut setup before I sorted it. Nine times out of ten it's the input current limit set too high for what the campsite hook-up can actually deliver — most UK...

ExFirefighter59 | Posts: 847 @MuddyRanger Worth checking whether you've got the BMS tail current feature enabled in VictronConnect - if the MPPT can't "see" the actual charge current...

JakeShaw96 | 847 posts | ⚡ Solar Enthusiast Proper timing on this thread @VitoBuild — similar situation hit us last February, about 36 hours without power. What saved us was running a decent...

@KeithClark71 yes, had exactly this with my 75/15 during my van build. Turned out my phone's Bluetooth was dropping into a low-power state — Android does this aggressively in the background.

SmartSolarFan | Posts: 1,243 @PanelBuff Agree with @LakelandWanderer and @GoldenNomad on the 30A being the better fit here.

@FogstarGal raises a good point about internal resistance, but I'd add — are you using temperature compensation on the charge voltage?

@RogerKnight one thing I'd add is that lithium's acceptance rate matters here too. A 200Ah lithium bank will happily gulp down whatever the 30A unit throws at it, so you're genuinely getting that...

Hey @DanFisher89, yeah this is a pretty common one with Daly units. The low-temp cutoff protection kicks in around 0–5°C on a lot of them to prevent charging damage to the cells — which is...

Right, @DanFisher89 don't you dare leave us hanging as well! 😄 @ExFarmer21 — what I suspect nobody's quite got to yet is that your fix is probably straightforward.

@DazHenderson77 Living on a narrowboat means every day is an "OH NO" box situation — mine's just called the boat.

Been down this exact road with my motorhome build last summer. The split-charge relay itself is fine on a budget — picked up a voltage-sensing relay (VSR) off Amazon for about £14 and it's been...

Something worth adding that I haven't seen mentioned yet — check the input voltage threshold settings in the VictronConnect app.

Hey @OffGridDoug, worth mentioning that the Bluetooth monitoring alone has saved me a fair bit of head-scratching on my Transit conversion.

@DuctTapeDave60 worth flagging that a basic VSR/split-charge relay won't play nicely if you eventually want to add solar into the mix — you'll get backfeed issues.
