RVPOZWER 12V Lithium Battery 100Ah $99 ,48V 100ah $432
@LesWood78 curious what you found inside — dodgy cells or the BMS that was the weak point? Either way, avoid.

Anyone else noticed their electricity bills absolutely rocket this month?
Charging the EV off solar has basically made petrol station anxiety a distant memory. @BenJackson gets it. My setup's nothing fancy — just enough panels to keep the car topped up most of the year.

Multiplus II erratic behavior during transitions
@VoltJohn had exact same setup last winter — Multiplus II 3kVA with a Fogstar Drift 48V. What fixed mine was tightening up the battery communication settings in VE.Config.

Industrial Microgrid Design: Solar VFD Loads First, Export Excess PV to Generator-Based Grid
Been thinking about this setup a lot lately after chatting with someone running a small fabrication workshop off-grid. The concept is solid — prioritise your heavy three-phase VFD loads directly...

Wired up a 400W solar array to my garden office last month — here's what I learned
Running a similar rig for EV top-ups on a Leaf — same Victron controller, pair of panels. One thing nobody's mentioned: shade matters more than you'd think with a series string.

Anyone else running lithium on a narrowboat? Swapped out my lead-acid bank last month and a bit confused about charging sources
@GillWard Worth adding — your solar situation matters a lot here. What panels are you running and through what controller?

Anyone else had their BMS cut out mid-storm when they needed it most?
@KevLee seen this exact scenario. My Fogstar did something similar last winter — turned out the cell voltage imbalance had been quietly building for weeks and the storm conditions just pushed it...

Anyone else finding the Victron Orion-Tr Smart a bit oversized for a small van build?
Ran a 12/12-18A non-isolated in my setup for ages before upgrading. Honestly? The 30A earns its keep faster than you'd expect once you're running bigger loads off the leisure bank.

Tiny cabin build in the Scottish Borders — what size battery bank am I actually looking at?
@DaiWalker61 Scottish Borders is going to hammer you in winter — short days, low sun angle, lots of overcast.

Quattro 12/5000/120 charge current limit
Right, let me actually answer the question before the gremlins get me too — On the Quattro 12/5000/120, the AC input current limit feeds the charger and any loads simultaneously.

Victron Orion 30A keeping my leisure battery topped up but cuts out on long runs — normal?
@SolarNotSure where is it mounted though? That's usually the culprit before anything else. Mine was tucked in a poorly ventilated locker — moved it somewhere with airflow and the problem vanished.

Wiring guide help
@BorderVanLifer been there. DC cable alone nearly floored me — people forget you need serious gauge stuff between the battery and Multiplus, not the thin roll from Screwfix.

Growatt SPF3000 and JK Inverter BMS - Works!
Running a similar setup here — SPF3000 paired with JK BMS on a 16s LFP pack (Fogstar cells). Comms was the main headache for me too.

Anyone else's battery monitor acting dodgy when it's cold?
Yeah, mine's been a right pain in the arse lately. Victron BMV-712 here, and when temps drop below about 5°C the voltage readings start drifting — nothing dramatic, but enough to mess with your...

Working remotely from a van — power needs
Mate, the measuring thing is spot on but don't forget about your charging strategy once you've got the numbers.
