@PeakVanLifer yeah had this on my static when I first set it up — drove me absolutely mental for weeks.
Worth checking your transfer switch settings too, people always overlook those.
@Cerbo_Geek ran into almost this exact thing on my cabin setup last summer. The CVL from the BMS via DVCC is supposed to throttle the MPPT smoothly but in practice I found the SmartSolar was a bit...
The bit nobody mentions until it's too late — laptop chargers, USB hubs, random kit left on standby.
@CornishBoater worth checking your panel Voc vs your battery voltage — on really flat grey days I've seen my array voltage barely creep above what the controller needs to actually kick in and...
Had the same drift issue on my static with a similar mixed MPPT setup. One thing worth checking that nobody's mentioned — your charge efficiency factor in the BMV settings.
@DalesCruiser running a static caravan off-grid here so similar ballpark really. Honest answer — winter is manageable but you have to respect it.
My setup is 600W panels, 400Ah Victron lithium,...

@FormerMariner24 worth knowing the 24/1200/25 will handle a kettle just about but it'll be working hard — I learned this the hard way in my static.

Worth checking your panel voltage at the controller input in those flat grey conditions — I was convinced my Victron 75/15 was playing up last February until I...
The bit nobody's mentioned yet — check your Voc figures before wiring anything in series. Three panels in series on a cold morning can spike surprisingly high, and the 100/20 has a 100V absolute...
@MeganStevens yeah this is the exact rabbit hole I fell down last winter with my cabin setup.
The Fogstar Drift doesn't have a BMS that talks to the Cerbo natively which is the frustrating bit.
@MoreTeaVicar ouch, that's brutal. Had something similar on my static a couple of winters back — lost one panel completely and another cracked along the frame.
What saved the others was switching...

@KenCross mine's not in a van but I did run a Renogy DCDC in my cabin setup for a while before switching to Victron — and yeah, warm is normal, hot is when you want to start worrying.
One thing...
Not directly relevant to Growatt but might help someone — when I was sorting my static caravan setup I had constant grief with protocol mismatches until I actually rang the battery supplier...
@DODQueen you're spot on about freshwater being the real culprit. @KentCruiser's right about the passivation issue — it's one of those things that catches people out.
What's worked for me on my...
The middle ground does exist, but it depends massively on what you mean by "family." Two adults with a caravan? Totally doable.
