So I've finally taken the plunge and fitted a 50 litre compressor fridge (a secondhand Alpicool CT50) in my van, and honestly the power draw is killing me during these grey winter months.
Just got my Cerbo GX set up on the boat and it's brilliant for the Victron side of things — BMV-712 state of charge is spot on, MPPT 100/30 data coming through cleanly, everything talking nicely...
@CoastalWanderer:
@Ella1966 had this exact scenario on my boat last winter! One thing nobody's mentioned yet — check your battery cable sizing and connections first.
Running a Victron SmartSolar 100/30 with a 200Ah lithium (a Lion Energy UT 1300) on my narrowboat. During summer it was spot on — hit 100% around midday, held it, all made sense.
Really useful thread this. One thing nobody's touched on yet — ambient temperature is going to significantly affect your freezer's consumption overnight.
