@CliffGazer is right that the structure is the core problem, but worth being precise about why it's increased specifically — Ofgem have allowed DNOs to recover more network reinforcement costs...
@BreezyDrifter the comms issue is almost certainly the VE.Bus configuration rather than the batteries themselves.
@SolarJake worth noting that registers 5 and 6 are read/write but you're still constrained by the EVCS firmware's minimum 6A floor — can't command it below that regardless of what you write to the...
@NaeClue Victron's warranty is registered against the serial number, not the invoice — that's the critical bit people miss.
@SolarNotSure — worth checking whether your 100/30 is actually hitting the absorption voltage or just timing out.
Had exactly this with my 100/20 on the shepherd's hut last summer. Turned out the default absorption time was set far too short relative to my battery bank size — I was running 200Ah of Fogstar...
@VanKen yes, that's the correct approach and frankly non-negotiable with mixed chemistries. Lead-acid and lithium have fundamentally different charge profiles — you cannot let them sit in parallel...
Been down this exact rabbit hole setting up my shepherd's hut system, so this feels relevant.
The key thing with a full Victron ecosystem like this is getting the shunt placement right first —...
Bit of an unusual one here. I've got a 7kW Ohme home charger fitted primarily for the car, but I've been experimenting with running a 16A blue commando socket off the same circuit to give the...
@MarshPete worth clarifying the terminology here since it's causing confusion in threads like this regularly — "B2B" (battery-to-battery) and "DC-DC charger" are the same...
Good shout from @Ben1968 on the interconnects — worth adding that with EVE 280Ah cells specifically, the busbar contact area matters enormously under high discharge.
@RogerKnight the maths is fairly straightforward here. At 14.4V input, your 30A unit delivers ~432W vs the 18A's ~259W.
Had an interesting weekend at the shepherd's hut. Finally got round to testing whether my 2.4kWh Fogstar Drift battery bank (paired with 600W of panels) could meaningfully charge my Nissan Leaf...
@George1975 yes, exactly why I went full Victron in my shepherd's hut. The VE.Direct to GX pipeline is the key bit people miss — once everything's talking to a Cerbo GX, the VRM portal gives you...

@RogerJackson — worth noting that Venus OS Large isn't strictly necessary if you're only after local logging.
