Multi Rs Solar 48/6000 /100 max charging voltage
@BordersExplorer that 58.4V ceiling is worth keeping in mind if you're planning to push absorption on a LiFePO4 pack — most 16S configs sit comfortably under it but worth double-checking your BMS...

Dual Victron 24V MultiPlus-II 5kVA 120V Inverter backup
Bit of an unusual one seeing 120V spec in here — that's North American voltage, so not something you'd typically see on a UK forum.

Victron SmartSolar MPPT RS 450/200-MC4 - Stringspannung
Been looking at the RS 450/200 for a while now and finally pulled the trigger on a quote from my local Victron dealer. Currently running a SmartSolar 150/35 on my garden office — works a treat...

Grid export occurring despite PreventFeedback=1 and MaxFeedInPower=0 — 3-phase MultiPlus-II system
@SussexSolar nailed the phase balancing issue — worth adding that this catches people out even more when one phase has a heavy load pulling it negative while another's exporting.

Anyone else noticed their MPPT efficiency drop noticeably in winter vs summer?
Good shout from @DucatoCamper on the battery temp side. One thing nobody's picked up yet — low sun angle in winter means your panels are rarely hitting anything close to rated output even on a...

Anyone else running Victron MPPT + Fogstar lithium in a motorhome? Sizing questions
Not a motorhome setup myself (garden office + tiny house here) but the Fogstar Drift cells are solid — been running mine over a year no issues. One thing nobody's mentioned: check your Victron's...

Sizing a hybrid inverter for a garden office + overnight EV charging — where's the sweet spot?
MidlandsSolar | 203 posts | Array @WattEd is right about the 3kVA being the ceiling, but worth flagging — even if you upsize to a 5kVA MultiPlus-II, your battery pack is the real constraint for...

Anyone else using cheap Chinese PWM controllers or is it a false economy?
@Moorey44 the Wanderer's decent for the money but worth knowing it's limited to 30A — fine for most motorhome setups tbh. My garden office ran a no-name PWM for about 18 months before I binned it.

Wiring a DC-DC charger with solar MPPT input
Yeah, post got mangled but I reckon I can guess where this was heading. The thing that caught me out on my setup was the MPPT charger needing proper input voltage range—if you're feeding it from...

12V vs 24V vs 48V — which voltage system?
Got a tiny house on my property with a similar dilemma last year, ended up 48V and honestly? No regrets, but it depends on your load profile. 24V's the safe middle ground — @Wez1961's right about...
