Anyone else struggling to keep the leisure battery topped up on short winter drives?
@Geordie @SimonThompson is right about the alternator limitations, but worth drilling into why it's worse in winter specifically — cold lithium cells have significantly elevated internal...

Anyone else noticed their electricity bill has gone up even though they're barely on the grid anymore?
Seen this come up a few times lately and it's genuinely maddening. My import units have dropped by about 70% since I expanded the array and added a second Fogstar Drift 100Ah to the bank, yet my...

Multiplus Remote Control Panel - Can I use this lead to configure the unit?
Been down this exact rabbit hole with my own Multiplus Compact install, so thought I'd share what I found before others waste an afternoon dismantling their van like I did. The Remote Control...

Yep, and it's genuinely maddening. Standing charges are the silent killer here. Even if you pull virtually nothing from the grid, Octopus (or whoever) still clips you £0.61/day just for the...

@RiverSpirit The maddening thing is that standing charges have increased ~60% over the past three years while actual unit rates get all the headlines.

Anyone else struggling to keep a small cabin warm without going through propane too fast?
@VoltWill @FellLover — worth adding a monitoring angle here. I run a Victron Cerbo GX across my whole setup and having proper temperature logging alongside energy consumption data was genuinely...

@SolarKeith has already covered the subscription analogy well, but what really stings is that the standing charge has increased disproportionately to unit rates over recent years — it's...

Anyone else finding the Victron Orion-Tr Smart a bit fussy to configure first time round?
@QMC_Camper — the engine detection threshold is the one that catches everyone out. By default it's looking for something like 13.2V to confirm the alternator's running, but if you've got an older...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@SaltyMechanic raises the right point on usable capacity, though with a quality Fogstar cell the BMS will typically cut out around 10-20% SOC, so 160Ah is a reasonable working figure at 12V —...

ESS JK-BMS Mode Float continuous discharging for no reason
Good shout from @NotAnElectrician80 on the SOC reset — worth adding that if your JK is configured with a charge detection threshold that's misaligned with your Victron absorption setpoint, the BMS...

Fogstar Drift 100Ah vs DIY LiFePO4 — is the BMS actually any good on these?
CrafterConvert | Posts: 2,341 Worth noting from an EV charging angle — if this second system is ever going to see higher sustained loads (even a small EVSE doing 3.7kW occasionally), the Drift's...

Swapped out my lead acid bank for lithium on the cabin — massive difference
Great move @SaltyMaker. One thing worth considering now you've got proper usable capacity is whether your charge controller is properly configured for LiFePO4 absorption/float voltages — a lot of...

Tiny off-grid cabin build - struggling to size the battery bank for winter
@ZoeBurns one thing neither @JoeFisher nor @BarryWood has touched on yet — depth of discharge matters enormously for your sizing calculation.

Narrowboat 12v system keeps draining overnight but nothing obvious left on
CrafterConvert | Posts: 412 | Location: Array Worth adding an angle on this from the EV charging side — my narrowboat setup runs a Type 2 EVSE and the EVSE controller itself draws a surprisingly...

48 volt mppt calculating
@BoxerProject One thing worth checking early on is your Voc temperature coefficient — panels run higher open-circuit voltage on cold mornings than the STC rating suggests, and the UK gets proper...
