@OldSailor already covered the pedantic bit so I'll add the actually useful bit — make sure your Cerbo GX firmware is current because pre-v2.80 had a delightful bug where the Skylla would...
@PaulCross T105s are fine until you realise you're only ever using 50% of the capacity you paid for, hauling them around like anchor weights, and topping them up with distilled water like it's...
@T6Project 215W at 24V nominal means Voc is probably pushing 37-38V, which is fine for the 100/20's 100V input limit — maths works.
Real problem is your 20A output limit: 215W ÷ 12V = ~18A...

@WattAMess25 is right about freezer type, but the number everyone keeps ignoring is ambient temperature — a chest freezer in a black Transit in summer is...
@SimonThompson on a 48V system with no solar, make absolutely sure your MultiPlus-II charge settings match the Fogstar Drift's BMS limits exactly — absorption voltage, float voltage, charge...
Intermittent cutouts on Orion chargers usually point to thermal shutdown kicking in—check if the case is getting proper airflow and isn't coated in dust.
PWM's fine until it isn't, then you're leaving 20-30% of your potential on the table. @MariaJones isn't wrong with the potato analogy.
Victron SmartSolar 100/50 MPPT is the sweet spot for most...
8kW sounds cracking on paper until you factor in real-world losses, shading, and the fact that most EVs want 7-11kW minimum to charge meaningfully—you'd be throttling hard come winter.
The...

Got Grafana running on a Raspberry Pi pulling from my Victron CCGX and it's brilliant for spotting patterns you'd never catch on the display alone—like how my morning cloud cover costs me a solid...
Families work if you're honest about winter consumption and don't cheap out on battery storage—I've seen too many converts discover their 10kWh system won't cut it come January.
The real question is: what's your duty cycle looking like? I've got a MultiPlus (original) running my van conversion and it sits idle most of the week — that 2-3% efficiency gain would be utterly...
Pure sine every time for me — MSW inverters are false economy, especially if you're running anything with a motor or switched-mode power supply.
Depends what you're actually doing though — if you've got alternator charging in a van, relay's still the move.

Right, so I've been through the DVLA wringer twice now with my van conversions and let me tell you — it's less a regulatory framework and more a game of "what mood is your local examiner in...
Flat wins on a narrowboat, mate — you'll be repositioning that roof constantly anyway when you're navigating locks, and a tilted array is a guaranteed head injury waiting to happen in the...
