Been running the same unit for about eight months now and had similar bother early on. One thing nobody's mentioned yet — check your phone's Bluetooth settings and make sure battery optimisation...

I've been running a Cerbo GX as the brain of my system for about eight months now and overall it's been brilliant for keeping an eye on things.

Ha, love this thread — count me in as another offender! 🙋 Running a Cerbo GX on my little Welsh hillside cabin — 500W panels, two Victron 100Ah lithiums, and a Multiplus 12/2000.

Had this exact issue in my shepherd's hut build last year. Turned out my absorption time was set way too short in VEConfigure — default can be stingy depending on your battery profile. Worth...
@KangooAdventure yeah January has been oddly productive hasn't it — I've been pleasantly surprised on my narrowboat too.

@NickMason had almost identical with my boat bank — JK 200A, EVE 280Ah cells. Turned out to be the balance wires.

Reply by WrongFuse83: @Ian1968 great little setup you've got there. One thing I'd flag from bitter experience — keep an eye on where you're placing any humidity sensors or electronics relative to...

RobButler | 312 posts Great point from @ThingamyBob62 about the van wiring — I'd extend that to think about your connection points too.

GrumpyHermit | 847 posts | Joined 3 years ago @NickMason worth checking your cell interconnect torque as well — loose busbars cause resistance which causes voltage drop under load which triggers...

Finally pulling the trigger on sorting out a proper off-grid setup for my little timber cabin near Shrewsbury.

@Boycie the Daly isn't bad per se, but it's essentially a dumb protector rather than an active manager.

@MeganStevens one thing worth adding — panel voltage matters here. If your 100W panel has a Voc around 22V you're losing a fair chunk to PWM inefficiency, especially on dull UK days when the...

@OldSparky18 three cells of my first Drift batch behaved identically to yours — sat stubbornly at 3.63V after resting whilst the fourth crept up to 3.65V on its own.

@PanelDai the SmartShunt will give you accurate DC-side current draw when the inverter kicks in, so you can at least infer what it's pulling.

Great thread, lots of good suggestions already. One thing I'd add @HighlandNomad — have you checked your absorption voltage setting in VEConfig?

Really good timing on this thread - just helped a mate spec out something similar last month. One thing nobody's touched on yet is the Drift's low temperature cutoff.

@MasterCamper I've had exactly this on my cabin setup with a 200Ah LiFePO4 — the BMS low-temp cutoff is doing its job but it's frustrating when you just need power. Few things worth looking...

Just fitted a Victron SmartSolar MPPT 100/30 to my Transit camper build last weekend. 200W of solar on the roof (2x 100W panels in series), feeding into a 100Ah lithium (Battle Born).

Really depends what you're asking the system to do, honestly. If someone's just topping up a partially discharged AGM after a few hours driving, a relay probably won't cause obvious problems in...
