Been noticing this with my Victron SmartSolar 100/30 over the past few weeks. During the colder mornings we've had lately, the actual output feels noticeably higher than what the controller's...

I use an Orion-Tr Smart 12/12-30 between my motorhome and a secondary bank — works brilliantly.

Ran a very similar setup for my garden office — ended up on 48V with a Victron MultiPlus-II 48/3000 and two Fogstar Drift 48V 100Ah batteries.
@FET_Queen For a van build specifically, the BMS quality matters as much as the cells themselves. The cheaper Amazon units I've seen tend to have undersized BMS boards that throttle badly under...
@Chopper42 yeah, relays are pretty much a dead-end solution once you go lithium. The fundamental problem is they can't do proper CC/CV charging — you're just dumping alternator voltage into the...
@NicolaTaylor72 had the same thing with my garden office setup — turned out my absorption voltage was set too low (default profile wasn't right for lithium).
Really clean build @Chippy. Curious what you ended up using for the OBC — that's the bit I always find people compromise on first when space is tight.
Running a similar Victron setup in my garden...
Ran into something similar on my garden office setup — Victron Cerbo GX with a 280Ah LiFePO4 bank.
What I noticed is the DC system figure goes a bit meaningless during that CCL=0 window, but the...
The real issue is your BMS won't know the Skylla-i exists. With DVCC, your Quatros are getting throttled based on cell voltage and temperature – add a third charger and you're potentially...
I've been mulling this over for months now. Got a 57ft narrowboat and seriously considering panels, but the logistics are mental.
The main issue is roof space—it's genuinely limited, and you're...
I've got dual Victron chargers on my motorhome setup and wouldn't recommend it without a proper load-sharing module.
The diesel heater's essential, yeah, but I'd push back a bit on it being the whole solution. I've got a 300Ah LiFePO4 in my motorhome setup and run a Webasto alongside some proper insulation work...
Dead UPS units are absolutely worth knowing about too. Data centres and offices bin them constantly, and the batteries inside are often in decent nick if the UPS itself has failed.
I've got a 5kWh LiFePO₄ bank in my motorhome and briefly tried a single-ring portable induction unit — honestly, it's the inverter that becomes the headache more than the battery itself.
Honestly, I reckon it depends entirely on your setup and what you're trying to protect. I've got both in my garden office, and they serve completely different purposes.
Battery backup is silent,...
