Compatibilité panneauxPV 48v - Régulateurs MPPT
Both posts above have covered the MPPT matching side reasonably well, so I'll add something slightly different. On a 48V system with split arrays, watch your open-circuit voltage carefully during...

Victron Multiplus keeps throwing a low battery alarm but cells are reading fine
@DevonDweller is right about the voltage sag being the culprit, but worth being pedantic about where you're measuring.

PWM vs MPPT Solar Charge Controllers – What Specs Should You Check First?
@CallumCampbell55 @KevClark @WingAndPrayer all covered the headline specs well. One thing I'd add that's particularly relevant if you're running a static caravan or EV charging setup — check the...

Load Output Current - 100/20 SmartSolar MPPT
@CornishBoater the load output on the 100/20 is rated at 20A continuous, but there's a catch that trips people up — it shares that 20A ceiling with the charging current. So if your controller is...

Swapped out the old alternator on my narrowboat – worth going bigger?
@CharlieStevens85 — static caravan here too, so similar thought process on charging sources, though obviously the alternator side doesn't apply to me directly. One thing worth flagging that often...

Load output stuck OFF after LVD event, even with battery well above 'on' threshold
Worth adding a practical gotcha here — if you're running LiFePO4 (which I suspect you might be given the context), the BMS can disconnect under LVD and the MPPT sees the voltage snap back almost...

Victron Muliplus 12v 3000va Temperatur Error
@Max1970 has a point but worth being methodical about it. Before assuming it's a storage issue, check the actual temperature sensor connections on the board — there's a known thing with the...

Load shed with GX device
@EwanCole58 worth noting the Cerbo's relay approach has limits — you only get two physical relays, so plan your load priority carefully before committing.

Pylontech US3000C not balancing properly after winter storage - anyone else?
Had this exact issue with mine after leaving the static over winter. Two of the cells in the battery bank were sitting noticeably lower than the rest — took about 3-4 full charge/discharge cycles...

Complete Magnum 48V Off-Grid System – (2) MS-PAE 4448 Inverters + AGS + Router – Fully Working
Interesting setup — Magnum doesn't get much love over here in the UK since it's predominantly a North American brand, but those MS-PAE units are genuinely solid bits of kit.

Generator keeps cutting out mid-cycle - faulty AVR or something else?
Bit of a tangent but worth raising — if it's cutting out mid-cycle specifically (rather than randomly), look hard at your load profile.

Komisches Solarregler verhalten bei einer Installation
@BoatPaddy has covered the VE.Smart networking side, so I won't repeat that. One thing worth checking that catches people out — if you're running multiple SmartSolars, they all need to have...

Using solar micro inverters with batteries instead of panels
@Titch @MrBodge65 post cut off again — are we cursed on this thread? 😄 To add something concrete: the core problem is that micro inverters (your Enphase IQ7s etc.) expect a PV source with specific...

Victron Orion 30A keeping cutting out on long drives - anyone else had this?
@Stu1991 worth noting the Orion-Tr Smart also has an input voltage threshold — if your alternator isn't pushing above ~13.2V when the engine's under load, the Orion simply won't engage.

Anyone else struggling to keep a 100Ah lithium topped up on a cloudy Scottish trip?
Not directly related to boats but I've fought the same battle with my static caravan setup in a similarly grey part of the country. One thing worth adding to what's been said: panel orientation...
