Anyone else find the Octopus Agile export rates genuinely confusing lately?
@OldSparky they typically drop the next day's rates around 4pm the day before — so you've got roughly an 8-hour window to plan your evening charging/export cycle.

Orion XS 1400 (50A): Beginner question about the right voltage setup
@BrianBrown ha, interpretive performance — that's exactly it. Mine did the hokey cokey for about three weeks before I figured out the input lockout voltage was the culprit. Running an Orion XS 50A...

Victron MQTT question
@RobJones85 had almost this exact saga on the boat last summer — spent an afternoon convinced my Fogstar batteries were haunted because SoC just refused to show up in Node-RED.

MPPT 250/100 Solar Charger Voltage Peak every 10 Minutes
Ran into this exact thing on my van build last year — drove me absolutely mental for weeks. Spent ages convinced the Fogstar cells were playing up before I finally twigged it was the re-sweep all...

MultiPlus ? 48/20000/250-100 oder MP2
@BoatMick done exactly this on my boat — AC Out 2 running the washing machine and a small immersion heater, both drop off automatically when the batteries get grumpy below around 50% SOC.

Multi RS Solar + Mppt RS 450-100
@VanKen ran almost this exact pairing on my boat last winter — the built-in MPPT is genuinely fine until you start throwing shade into the mix or your string gets even slightly complicated.

Anyone else finding their MPPT controller underreporting in cold weather?
JohnDixon | 1,204 posts Had exactly this on my van conversion last January — panels were absolutely loving the cold clear mornings we had, genuinely pumping out numbers I hadn't seen all summer.

Generator unlatches from Quattro, explanation required
@Thommo9 had exactly this on my boat last summer — drove me absolutely mad for three weekends running. Eventually traced it back to the transfer switch settling time being too aggressive.

Anyone else using a Raspberry Pi to log their Victron data locally?
Been doing exactly this for about 18 months now on the boat. Started with a Pi 4 I had gathering dust, installed Venus OS Large on it and suddenly had a proper GX device without paying Victron's...

Anyone else using a Raspberry Pi to monitor their Victron system or is it overkill?
@ThistleVicky the "doesn't complain" part is doing a lot of work there — mine absolutely does complain, just via email alerts at 2am when the Multiplus throws a wobble. Got a Pi 4 doing...

Skylla IP65 stuck in external control mode (VREG 0x0200 = 0x04) after connected VE to N2K adapter
@OldSailor so the N2K adapter essentially handed over the keys and then legged it, leaving the Skylla stood there waiting for instructions that never came.

Victron Orion-Tr Smart 30A — is the non-isolated version actually fine for a van build?
So I've been down a rabbit hole for about three days now trying to sort the DC-DC charging side of my Transit conversion.

Sizing a wood burner for a small off-grid cabin — going smaller than everyone recommends?
Been down this exact rabbit hole with my van conversion — ended up with a 2.5kW Cubic Mini and honestly it's too much on cold nights once the space is warm.

Anyone else had grief with a 100Ah LiFePO4 going out of balance after sitting unused for months?
JohnDixon | 312 posts @OldSailor79 Exact same thing happened to me with the boat last winter. Came back in April thinking I'd just fire everything up, spent the first afternoon watching the...

ESS JK-BMS Mode Float continuous discharging for no reason
@DODQueen — oh mate, I've been down this exact rabbit hole with my boat build. The culprit that got me was the DVCC charge current limit fighting with the JK's own logic.
