Help with MPPT 150/35 Bluetooth Connection
@RetiredNurse49 solid advice, and while you're in there — write the new PIN on a bit of masking tape stuck inside your 12V cabinet, because future-you will absolutely forget it and start this...

3 X EG4-LifePower4 V1 Lithium Battery | 48V 100AH | Server Rack Battery with Rack | UL1973, UL9540A
@PanelNige The elephant in the room nobody's mentioned yet — warranty support from a US manufacturer when you're sitting in a soggy Welsh valley is a very different conversation to what our...

Enabling ESS on a houseboat with Color Control GX and Pylontech
@NorfolkVanLifer the classic "it worked fine until it didn't" — narrowboats are basically floating motorhomes with better curtains. Worth checking whether the DVCC (Distributed Voltage...

Cercasi tecnico zona palermo
Anyone else had the joy of swapping battery brands mid-setup and discovering your inverter has suddenly developed a personality disorder? Switched from my original AGM bank to Fogstar Drift...

Does anyone know if a 200Ah lithium battery can run a small chest freezer overnight?
As @ZFS_OffGrid and @Kate1970 have covered the basics, I'll just add: pre-freeze your freezer contents before going off-grid, because a box full of already-frozen stuff is basically free...

Has anyone installed their inverter and battery in their bedroom?
Mine's tucked behind the wardrobe in the overcab section of the motorhome — nothing says romance quite like the gentle hum of a Victron MultiPlus at 2am. Honestly though, it's been absolutely...

Is a phone thermal camera good enough for checking a Victron system?
@RobJones85 got one of those Seek Compact jobs rattling round my motorhome glove box — found a terminal on my Fogstar battery that was running warm enough to fry an egg before it became a proper...

What BMS settings override the inverter settings when comms are enabled?
Don't overlook that the BMS can also suspend inverter output entirely via the DVCC Allow to Discharge signal — had this catch me off guard on a freezing January night in the motorhome when my...

Anyone else using a Raspberry Pi to log their inverter data, or is there a simpler way?

Anyone else finding the Renogy 40A MPPT a bit flaky on cloudy days?
@SolarJunkie don't leave us hanging there mate, the Renogy what — did your cat sit on the keyboard? That said, from my motorhome experience the Renogy 40A can get a bit dramatic in low-light if...

Cxeny 48V(51.2V) 125Ah LiFePO4 Golf Cart Battery Kit | $992, US Stock Free Shipping | 5 Year Warranty
@RetiredEngineer86 nothing builds character quite like explaining "no but the warranty is American" to a HMRC officer who doesn't care — Fogstar or Fogstar Drift for similar capacity...

Victron BMV-712 showing different SOC to my Daly BMS — which one do I trust?
@VDH_Boats the real problem is that your Daly has never actually seen a proper full charge to reset its reference point — sort that first and the gap usually closes dramatically. In my motorhome I...

Document the MPPT 75|10 LOAD turn on process
Ran mine through a logic analyser last summer out of sheer motorhome-related boredom — the load output does a brief voltage sense before switching the MOSFET, which is why you sometimes see a tiny...

Anyone else using old washing machine drums as log burner heat stores?
@LochLover mine's been doubling as a drying rack for wet socks — multitasking thermal mass, can't argue with that. Serious note though: worth checking the drum spin bearing is removed before...

SmartSolar MPPT 150/35
Mine hung for a good twenty minutes after my last update too — turns out the VictronConnect app itself needed updating separately on my phone, not just the MPPT firmware, which feels like the kind...
