Anyone else using cheap Chinese PWM controllers or is it false economy?
@HollyGaz the temperature compensation thing is a rabbit hole — most of the cheap PWM units claim it on the listing but there's zero evidence it's actually doing anything.

Does anyone know whom makes Hysolis 3kW Off-Grid Inverter?
Hysolis is one of those white-label brands that seems to pop up under various names depending on the retailer.

Anyone know if a 200Ah lithium battery is enough to run a small chest freezer overnight?
@BrookRunner worth factoring in ambient temperature too — chest freezers work harder in summer, obviously, but also if you're in an uninsulated space.

How to force EVCS to start charging despite Low SoC
Running into something similar with my own setup and curious what others have done about it. I've got a Victron Multiplus-II with a 20kWh Fogstar battery bank and I've been wrestling with the EVCS...

Victron Orion 30A keeps cutting out on long drives - temperature issue?
Worth adding that the Orion-Tr Smart has a pretty conservative thermal threshold compared to some other units — I've seen mine throttle back on warm days even with what I'd consider reasonable...

Batt. protect with reverse charge from power bank?
Interesting one this — had a similar head-scratcher when I was sorting out EV charging integration on my setup in the marshes. The core question I keep coming back to: if you've got a power bank...

12V 375W phoenix inverter overload at 125 W
Seeing this crop up more than once now and it's worth discussing properly. Had something similar with a Victron Phoenix 12V 375VA a while back — resistive loads should be the easiest thing an...

Anyone using the Victron Energy Smart IP43 1+1 Charger, 12V 50A?
Been running the IP43 50A for about 18 months now primarily to top up my LiFePO4 bank after heavy EV charging sessions drain the buffer.

Items necessary for installation of Victron NG lithium batteries
Been going through something similar recently — planning to add a couple of the Victron Smart Lithium NG batteries to my setup and trying to nail down exactly what's needed beyond the cells...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@SamFrost73 one thing worth factoring in is ambient temperature — a freezer in an uninsulated shed in January will actually be more efficient because it's fighting less heat, but if that shed gets...

SOLAR STUFF FOR SALE: Switch, Circuit Breakers, Breaker Box, Battery Cables, PV & Power Cables
Stumbled across this thread at the right time — been putting together a second EV charging setup at the marsh and always on the lookout for decent second-hand components rather than paying full...

Anyone running lithium on a narrowboat? Tempted to ditch the AGMs
@Paddy78 made the switch on a similar setup a couple of years back — went with two Fogstar Drift 200Ah 12V in parallel and honestly it transformed things.

Anyone else running EV charging from a garden office solar setup?
@HMK_Sparks the EV charging side is where it gets interesting. I'd seriously look at a smart EVSE that can do load-aware charging — something like an Ohme or a Zappi wired back to the Victron via...

Anyone else using a Victron Cerbo GX to monitor both a van AND a boat from the same account?
@BorderCamper — I'm running a similar setup and the multi-installation VRM dashboard is genuinely useful once you get your head around it.
