Anyone else noticed their electricity bill jump again this month?
Yeah, October price cap has absolutely done a number on my bills for the grid-connected stuff I still draw from time to time.

Victron MPPT keeps dropping to float way too early — anyone else had this?
Had exactly this with my 100/30 last summer. Drove me absolutely mental for weeks before I figured out what was going on. In my case it was the battery voltage sense.

Worth adding — double-check your BMS communication if you're running lithium. Had this exact headache with my Fogstar Drift cells last year.

Monitoring multiple batteries with Cerbo/Ekrano GX using CAN-bus BMS HV Protocol
@ThistleVicky had almost identical situation with my setup — what actually helped me was designating one Drift as the "master" communicator and using the others in a managed parallel...

PWM vs MPPT Solar Charge Controllers – What Specs Should You Check First?
Been down this rabbit hole quite a bit when I was speccing out my battery bank setup, so thought I'd chip in. The first thing I always check is the maximum input voltage (Voc) — get this wrong and...

Smartshunt phantom currents and power company transformer
@CamperClive worth checking your shunt's negative terminal connection quality first before chasing transformer noise.

DEYE BOS B: 215kWh LiFePO4 + 125kW 240V Three Phase Inverter + 200kW MPPT
@DailySolar makes a fair point actually — I've spoken to a couple of smallholding owners who are genuinely looking at this scale.

Multiplus 2 3000 GX with sunwaytech 5.22kwh battery
Interesting setup — curious how this pans out for others running the Multiplus 2 3000 with non-Victron batteries. I went through something similar last year.

Anyone else using Victron's VRM portal to track seasonal patterns in a shepherd's hut setup?
@T5Wanderer agreed on sunrise SOC being underrated as a health indicator — I'd add that if you plot it weekly rather than daily you filter out the noise from single overcast days and the seasonal...

Anyone else had grief with their Victron Multiplus cutting out under load in cold weather?
@RhysGrant one thing nobody's mentioned yet — check where your Multiplus is physically mounted. I had mine tucked in a poorly ventilated spot and even in cold weather the internal temperature...

Anyone else obsessing over their Victron Cerbo GX dashboards at 2am?
@DriftGal the 2am thing is real but honestly the dangerous phase for me was when I set up custom alarms on VRM.

Anyone else running Fogstar Drift lithiums on a narrowboat AND a van — worth the faff of mixing setups?
@PanelBuff is right about charging profiles but I'd add — the bigger headache on a narrowboat vs a van is your alternator charging setup.

Multiplus-II 2x120 Question
@KangooDream yeah the post definitely got cut off, but I'll take a guess you were heading toward the 2x120V AC output question? The 2x120 variant is the North American spec - you'd want the...
