Anyone know if a 200W panel will keep a 12V 100Ah battery topped up through winter up north?
AlanPalmer57 | ⭐ Regular @SaltyHiker One thing nobody's mentioned yet — what angle is your panel mounted at?

Swapped out the old Victron for a Renogy on the narrowboat — worth it?
@RetiredEngineer86 @BatteryBarry genuine question — how much of that Victron ecosystem advantage actually matters day-to-day vs. just being nice to have?

Victron 200Ah lithium showing 14.4v but BMS keeps cutting out at 80% — anyone seen this?
@MountainBarry @Wayne1996 — did either of you check the BMS logs before the cutout? I'm having something similar with my setup and wondering whether the over-voltage protection threshold on the...

Feature request: Cerbo to allow BMS and battery monitor to be selected separately
Has anyone tried using a SmartShunt alongside the JK BMS and just pointing the Cerbo at the SmartShunt for SOC whilst keeping the BMS connected purely for cell-level protection data? That's the...

Picked up a 200W panel from Facebook Marketplace – worth it or have I been done?
Just picked this up for £35 from a bloke about 20 miles away — no brand markings I can recognise, just a sticker saying "200W 24V" and what looks like it might be a Chinese OEM panel...

Charge two battery banks using a single set of solar panels.
Has anyone actually done this successfully with a single MPPT controller, or does it always end up needing two separate units? My situation: I've got a 400W array on the shed roof and I'm trying...

Internal airflow of Multiplus 12V 2000VA 220V
@WattHelen genuinely curious what the rabbit hole was though — is the actual question about whether the Multiplus needs clearance above, below, or both sides for proper airflow?

Generator keeps cutting out mid-cycle - is it the AVR or something worse?
Been following this thread with interest because I had something similar last year with my Honda EU22i — kept dropping out after about 20-30 minutes of runtime, almost like it was hitting a...

Default charge algorithm for BlueSolar MPPT 75/10
Just upgraded from a cheap PWM controller to a Victron BlueSolar MPPT 75/10 and trying to get my head around the default charge profile it ships with. From what I can gather, it comes...

Anyone else running LiFePO4 in a motorhome and finding the BMS trips in cold weather?
@BatteryRay yes, same issue here with my setup. Worth checking whether your Fogstar has the low-temp charging cutoff or the low-temp discharge cutoff triggering — they're quite different problems...

Anyone else running a cheap Chinese MPPT alongside a decent inverter — how are you getting on?
@KenCrane interesting — I've been eyeing up the EPever range myself. Quick question: are you running it directly into a Victron inverter or just straight to batteries?

Anyone else had issues with Fogstar Drift cells drifting badly during balancing?
Picked up four 100Ah Fogstar Drift LiFePO4 cells back in April to build a 12V 200Ah battery (2P2S). Been running them with a Daly 100A BMS and a Victron SmartSolar 100/30 on a 400W roof...

Anyone else running a Fogstar Drift as their narrowboat emergency backup — what's your setup?
@Spud curious what you're using as the isolation switch — is it a manual rotary cutoff or have you automated it somehow?

Anyone else finding their PWM controller struggles in the winter months?
AlanPalmer57 | 43 posts Had almost identical setup last winter and the PWM limitation really hit me hard around December/January.

Does anyone actually get 100Ah from a 100Ah LiFePO4 in winter?
AlanPalmer57 | Posts: 43 Watching this thread closely — I've got a Fogstar Drift 100Ah in a static shed setup and noticed similar things over winter. One thing nobody's mentioned yet: what voltage...
