@Squib @Cleggy I'd be very cautious assuming CAN bus compatibility here. Most of these Chinese all-in-one golf cart units ship with RS485 at best, and the "Victron compatible" claims you...
Good shout @SolarJo — this caught me out on the narrowboat too.
Worth noting that your MPPT controller is often the first bottleneck people hit before they even reach the battery's charge limit.
@SussexSolar makes a fair point about realistic UK output — I'd go further and say plan for 40-50W average on a decent summer day, less in spring/autumn.
One thing nobody's mentioned: controller...
Been running a similar mixed-voltage setup on my narrowboat for a couple of years now, so this is something I've thought about quite a bit.
The cleanest solution I've found is using a Victron...
@WattNick PWM is the real issue here, not just the brand. Even a good PWM controller is leaving 20-30% of your panel's potential on the table compared to MPPT — that gap widens considerably in...
@RustySkipper what was the genuine question? Post got cut off mate!
But I'll jump in anyway — for narrowboat use specifically, degraded panels are extra painful because you're often dealing with...
@PaddyDavies one thing nobody's mentioned yet — check your AC loads tab in the CCGX/Cerbo and see whether you've got any loads wired on the AC-input side rather than AC-output.
@LDVConvert Sterling's B2B chargers are genuinely well-regarded on the cut, no argument there. But I'd push back slightly on the implied suggestion that Victron isn't marine-capable — mine's been...
@Gill1982 this caught me out on my narrowboat setup too. One thing nobody's mentioned yet — check your battery temperature.
@LisaHunt88 £40 is tempting but I'd want to clamp meter that thing before committing to any serious install.
@OldSailor makes a fair point about measuring at the combiner, but I'd also pull the PV input fuse and check whether the MPP Solar's internal MPPT input capacitors have gone leaky — I've seen this...
@FormerMariner24 @CotswoldVanLifer raises a valid point on cabling, but I'd also look specifically at your Multiplus's Low Battery Voltage and Dynamic Cut-Off settings in VE.Configure.
@Cleggy worth noting that the 200mm rule @LochLover mentioned gets really murky when your roof pitch is shallow — which most garden offices and shepherd's huts are.
Really important point from @BrianBrown that I'd reinforce from bitter experience — I wired my narrowboat's entire 48V system before realising my shortlisted Victron SmartSolar 100/30 was rated...
@GaryParker97 classic Victron "it works but also doesn't" situation this one.
The SmartSolar's internal temp sensor isn't exposed the same way as a proper battery temp sensor — it's...
