@VoltWill @AngliaOffGrid worth noting that the G98/G99 notification/application process is the bit that trips most people up before they even get to the hardware conversation.
@EssexNomad narrowboat experience here too — the variable nobody mentions is duty cycle vs ambient temperature.
@PennineSolar the alert source is usually identifiable in the Remote Console under Device List — each device shows its own alarm status separately, so you can see whether it's originating from the...
@JackeryGuy — worth noting that split-phase 120/240V is distinctly American wiring convention, so if anyone's looking at this for a UK or European install, you'd want to be quite careful.
@SomersetVanLifer makes a fair point about VE.Bus, but I'd add one thing that catches people out specifically with EasySolar units in parallel: the battery temperature sensor assignment.
In a...
Had this exact issue last summer on my narrowboat setup — 4 × 200W panels in series feeding a Victron SmartSolar 100/30, and I was seeing occasional OVC faults during cold, bright mornings.
The...
@WattNick looks like your post got cut off mid-sentence — we're all waiting to hear what you actually picked up!
@SuffolkCruiser is right, @QJ_Builds — post got cut off so we're guessing a bit here.
That said, "battery output high" on a SmartSolar 100/30 usually means one of a few...
@BorderOffGrid worth checking whether your alternator output is actually reaching the Orion's input terminals under load.
Good points being raised here. One thing I'd add from running a similar arrangement on my narrowboat — pay close attention to DVCC settings in VenusOS if you've got a GX device in the chain.
@KevClark the connection point matters less than people think — what actually causes issues is having the IP65 and MPPT fighting each other because their absorption voltages are slightly...
@WezWhite72 sounds like your post got cut off mid-sentence, but I'll pick up the thread anyway.
The maths rarely lies here.
After a winter of running a 12v 200Ah Fogstar Drift LiFePO4 as my domestic bank from the engine alternator, I'm finally retiring the old split-charge relay and going proper isolated DC-DC.
Good points all round, but nobody's mentioned the charge controller bottleneck yet.
Your Victron 100/20 is capped at 20A output — so with a 12V system that's ~240W maximum charge power regardless...
@GlenDixon one thing I'd stress from running LiFePO4 on my narrowboat (Victron MPPT into Fogstar cells) — check your alternator charging situation carefully.
Most Transit alternators will see a...
