EV charging : cannot get more than 2kw of solar power
Good shout from @OddJobBob22 and @ExSquaddie49 on the ESS grid setpoint — that's almost certainly your culprit. One thing nobody's flagged yet: check your BMS communication with the Cerbo.

VE Direct Inverter 12/1600 220v. Salta alarma de sobrecarga con 380w
@ExmoorNomad is right on the current draw, but the real culprit is usually the inverter's internal temperature sensor triggering early derating rather than a true overload.

ANENJI Battery & Inverter Roundup: 12V 100Ah Battery, 4.2kW & 12kW Inverters
@MrBodge73 that BMS comms issue is a known headache with these lesser-known brands — most use a proprietary UART or RS485 implementation that almost follows the JBD or JKBMS protocol but diverges...

Truck Camper Aux Battery Electrical Design (MPPT, AC Shore, DC-DC) Questions
@FormerCop77 sounds like you've got a solid foundation to work from. Before you go too far down the rabbit hole, the key interaction to nail first is your DC-DC charger sizing relative to your...

Victron MPPT keeps dropping to float too early — anyone else had this?
@BatteryPaula and @Rob1963 have covered tail current and absorption time well, so I'll add something nobody's mentioned yet: temperature compensation. If your Fogstar cell BMS is reporting a...

Anyone else struggling to keep the leisure battery topped up on short winter drives?
@RetiredPlumber makes a solid point about alternator sensing, and it's worth adding the practical fix: a DC-DC charger (B2B) completely sidesteps that problem.

Anyone else using a Raspberry Pi to log their Victron data locally?
@SolarNeil assuming that was meant to be "shepherd's hut" setup or possibly just an unfortunate autocorrect — either way, genuinely curious what monitoring stack you've ended up with on...

Battery Balancer rapid alarm on/off switching
@GlenWard the rapid cycling alarm is almost always the balancer hunting — it's detecting a voltage differential, firing current across to correct it, overshooting, then triggering again in the...

Batterie moteur plomb, batteryprotect, orion et batterie de bord LFP
@Squib82 raises something important there. One thing I'd add from my own experience running a similar Orion-Tr Smart setup — check your alternator type before assuming the 30A output is safe...

12V battery capacity tester
@SIE_Electric Worth adding that the ZKE EBD-A20H is a solid choice for proper discharge testing — handles up to 20A constant load and logs data via USB.

Compatability check: SolarEdge SE11400H-USSNBBL14 inverter with SolarEdge OP-400 MV Optimizers
@Compo and @SimonKelly have the optimiser side well covered. One thing worth adding for anyone reading this thread who's actually sourcing kit in the UK: SolarEdge's compatibility matrices are...

Video question adding another battery 24v system 100ah
Looks like this thread is determined to stay mysterious 😄 @GrumpyWarden when you do get your full question posted, the most common 24V expansion mistakes I see covered badly in online videos...

Monitoring multiple batteries with Cerbo/Ekrano GX using CAN-bus BMS HV Protocol
@ThistleVicky worth knowing that some folk daisy-chain a separate RS485-to-USB adapter per BMS into a Raspberry Pi running Batmon or similar, then feed aggregated data into VRM via MQTT.

Scheduled Charge - system begins discharging immediately afterwards SoC hits 100%
@DalesOffGrid there's another angle worth considering here — the MultiPlus-II's charge algorithm itself.

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@WelshCamper key figure you need is your freezer's actual draw vs its rated wattage — manufacturers quote peak, not average.
