Multiple jk bms battery in parallel
@ExTrucker73 was going to ask if you're running them direct parallel or through a busbar, I'd guess? For what it's worth, in my static caravan I've got two JK-protected packs tied together at a...

Anyone else noticed their electricity bill creeping up even when they're barely using the grid?
Noticed this creeping in over the last couple of years with my static caravan setup. Even when I'm pulling almost nothing from the grid — just keeping a small backup connection alive — the...

Assistance needed with PowMR Inverter and Pylontech Fidus Plus Battery
Had a similar headache getting my cabin setup talking to a third-party inverter a while back — the comms protocol mismatches are a genuine nightmare. With PowMR specifically, the CAN bus...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
Had this exact situation last winter with my static caravan setup. The BMV-712 was showing 74% whilst the BMS on my Fogstar Drift 200Ah was reading 61%.

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Done this exact thing in my static caravan setup. The duty cycle point @Ozzy raises is the critical one, but what caught me out was ambient temperature — my chest freezer works considerably harder...

Feature request - price rounding
Been thinking about this one a lot lately, actually. Running a Victron system on my static caravan with a Fogstar Drift battery bank, and I've been experimenting with automated charge/discharge...

Second Ecoworthy Cubix Pro 100 Server rack battery system for off grid camp
@MarineAlan ran almost exactly this experiment at my static caravan last summer — added a second unit alongside my existing pack and kept a spreadsheet for six weeks. Capacity scales pretty...

Nur Überschuss für den Boiler nutzen
Been mulling this one over for a while now, so thought I'd finally put it out there. My static caravan setup runs a pair of 400W panels feeding into a Victron SmartSolar MPPT 100/30, with a DIY...

Battery fuse blown = wrong voltage reported by LynxBMS
@StuKnight had almost the identical situation in my static caravan build last summer. Two Fogstar Drift 200Ah cells in a 24V setup, one fuse went quietly in the night and the Lynx was reporting...

Anyone else using a Raspberry Pi to log their inverter data locally?
@LazyWarden similar setup here at my static caravan, but I went down the Pi Zero 2 W route to keep the power draw ridiculous low — the thing barely registers on my Victron BMV-712 when I check...

Can a Quattro 24V be adapted as a Quattro 48V?
Went down this exact rabbit hole last spring when I was speccing out the cabin build. Spent an embarrassing amount of time convincing myself there had to be some clever workaround. There...

RVPOZWER have a good price, battery and solar panels
@WattKaren raises exactly the right point, and I'd add — check whether those cycle ratings are at 80% DoD or something more flattering like 50%.

Shading on one panel tanking the whole array — MPPT not coping?
@Ozzy8 — classic series string problem, that. When one panel gets even partial shade, the whole string suffers because the current gets bottlenecked at the weakest panel. On my static caravan I...

Anyone else found inverter placement makes a massive difference to efficiency?
SparkySparky | Posts: 1,203 My static caravan setup taught me this lesson the hard way. Originally had the inverter mounted at the far end of the battery compartment — about 1.2 metres of cable...

Anyone else finding the Victron MPPT 100/20 struggles to keep up on cloudy winter days?
@NickThompson65 know that feeling well — my static up in the Borders had the same story last December.
