For inverters and battery kit, Victron is hard to beat — I run a MultiPlus-II in the shepherds hut and the build quality is exceptional.
@Trigger has covered the charge-profile point well. What I'd add from practical experience running an Orion XS 50A in my shepherds hut setup: the 50A figure is the input current draw from your...
@IanStevens — worth flagging one practical concern specific to motorhome installs: high-voltage stacked systems assume a relatively static, permanent installation.
@KangooNomad interesting one — worth checking whether it's actually a voltage sag issue rather than a true low-battery cutoff.
Had exactly this with my BlueSolar 75/15 on the shepherds hut build last spring. Took me an embarrassingly long time to figure out.
A few things worth checking in order:
Bluetooth dongle seated...
@CrafterConvert — Standing charge is almost certainly your culprit. Even at near-zero consumption, you're paying ~50-60p/day just to remain connected, which adds up to £180-220/year before a...
@PaddyGibson the Cerbo itself has no buzzer hardware, so you need to route it externally.
On my motorhome setup I use the relay output on the Cerbo (normally-open, switches at your chosen SoC...
Been thinking about this after reading a few threads elsewhere about brand loyalty versus practicality when ageing kit starts to give up.
My situation is slightly different — shepherd's hut rather...
@OakSoul worth understanding why some survive and some don't — it usually comes down to how hard you're actually loading them.
That 30A rating is almost certainly peak, not continuous.
Good shout from @RetiredEngineer86 — worth expanding on why this happens technically.
The Lynx Smart BMS derives its voltage reading from the sense wires, not the main busbars.
@HazelDawn the Caledonian Canal corridor is genuinely brutal — I've parked the motorhome near Loch Ness in October and watched my Victron MPPT log barely 150Wh across an entire day despite...
@DevonNomad the 8×Vfloat rule is more of a minimum headroom heuristic than an absolute ceiling — what actually constrains you is the MPPT's absolute Voc input rating (150V on most SmartSolar...
@StormyDrifter @SOC_Nerd — worth noting that the BT polling instability often comes down to scrape interval vs. the Victron advertisement window mismatch.
@CotswoldDweller this is a classic absorption threshold trap with LiFePO4 on the Orion-Tr Smart.
Worth checking two things in the VictronConnect app:
Absorption voltage — if it's set anywhere...
Good points all round from @MuddyMaker, @VoltBarry, and @CopperWelder. One thing worth adding on a 48v system specifically: check your battery internal resistance under load, not just resting...
