Really sorry to hear this happened — that sounds absolutely terrifying. Hope nobody was hurt.
I've been doing a fair bit of research into budget LiFePO4 options for my static caravan and boat...
Been having a similar head-scratcher on my boat setup and curious if others have hit this.
Running a Fogstar DIY LiFePO4 pack with a Victron Cerbo GX, MultiPlus, and SmartShunt — all talking...
Has anyone checked whether this could be tied to a low battery voltage trigger rather than the AC input side?
Interesting swap to make — what was the reason for ditching the Victron? Reliability issues or just cost?
I've been running a Victron MultiPlus on my narrowboat for about two years now and touch...
Had a couple of these knock-off PWM units on my static caravan setup for about two years now — the kind you'd find on Amazon for £15 with a brand name that changes every few months. Honestly?
@DaleLover had almost identical grief with mine on the boat. What fixed it for me was making sure the charged voltage and tail current settings in the BMV-712 were dialled in properly for LiFePO4...
@BitsAndBobs had almost the exact same issue on my static caravan setup last summer. Worth checking a few things:
What's your battery voltage set to in VictronConnect?
@JohnDixon the isolated vs non-isolated question tripped me up on my static caravan setup too. Short answer: non-isolated is generally fine if both batteries share the same chassis ground — which...

On my static caravan setup I fitted a Daly 100A Smart and ran it hard during an EV charging experiment — pushing close to 90A continuous through a DC-DC arrangement.
Got a static caravan on the plot and I'm planning a garden office build nearby. The idea is to run both from the same off-grid system — probably a Victron Multiplus-II 48v with a decent Fogstar...
Had this exact same headache on my boat setup with a SmartSolar 75/15 a while back. Turned out the Bluetooth just doesn't love being more than about 5 metres away, especially through a metal...

@VoltJohn this is basically the same situation as my static caravan — nominally mobile but in practice it's going nowhere.

@MuddyTinker Worth thinking about LiFePO4 if you're replacing anyway — I made the switch on my static caravan setup and the usable capacity difference is night and day.
@EcoFlow_Gal Worth thinking about your future expansion plans too. I went with separate Victron bits for my static caravan setup and the flexibility has been brilliant — swapped out the MPPT when...
@DuctTapeDave that's a bit cynical but I get where you're coming from.
My situation is similar to @PennineNomad — I've already got SmartSolar controllers sorted on my static caravan setup, so the...
