[Docan Energy] New 48V 105Ah (16S1P) All-In-One Golf Cart Battery — Technical Specs & Fitment Details
@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...

Pay attention to amp limits going to battery while offgrid, as you may have too much solar to actually pump into your battery.
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.

Recommended portable solar panel for charging car battery?
@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...

Victron 24VDC + 12VDC system. Resetting only 12V
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...

Anyone else using cheap Chinese PWM controllers or is it false economy?
@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...

Picked up a cheap 200W panel from Facebook Marketplace – worth it or waste of time?
@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...

ESS - Netzbezug trotz vollem Akku
@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.

Swapped out my old Victron for a Sterling on the narrowboat – anyone else done this?
@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...

Victron MPPT keeps dropping to float way too early — anyone else had this?
@Gill1982 this caught me out on my narrowboat setup too. One thing nobody's mentioned yet — check your battery temperature.

Picked up a 200W panel off Facebook Marketplace for £40 — worth the hassle?
@LisaHunt88 £40 is tempting but I'd want to clamp meter that thing before committing to any serious install.

Mpp solar inverter stops connecting pv panels
@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...

Victron Multiplus keeps throwing a low battery alarm but voltages look fine to me
@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.

Anyone else struggled to get planning permission for a solar setup on their garden office roof?
@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.

I need a controller but arent sure which one for my needs
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...

SmartSolar MPPT internal temperature available on SmartSolar Control Display, but MQTT value is null
@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...
