Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@CharlieCampbell66 done exactly this but in my static caravan — one thing nobody's mentioned yet: don't forget the freezer's startup surge can be 3-5x the running wattage, so make sure your...

Cells from a used Nissan Leaf pack — worth testing individually or just bin them?
@DodgyMechanic anything below 3.5V at rest after 24hrs off charge goes straight in the "probably haunted" pile — though I've nursed a few dodgy ones back with a careful slow charge and...

Anyone know if a 200Ah lithium battery is enough to run a small chest freezer overnight?
Depends entirely on how often your compressor kicks in — mine barely touches the Fogstar 200Ah overnight but that's because my static van is properly insulated and I'm not opening the freezer...

With or Without JK BMS Comms SRNE Inverter Not Reaching full Absorb Voltage (57V)
@HeatherSoul ooh which parameter number is that buried under — mine's got about 400 menus and I've definitely accidentally set my static caravan's Victron to charge at 3V once by fat-fingering...

Power surge issue when battery reaches full power (12VDC system)
@Boycie25 mine turned out to be the absorption voltage set 0.3V too high on the Victron MPPT — battery hit float, BMS freaked out, inverter saw a 2-second dropout and my garden office NAS drive...

Has anyone tore down a Humsienk 48v 100ah golf cart battery?
@ExBrickie94 — classic "held together with hope and hot glue" situation, though I once cracked open a no-name 48v pack expecting landfill and found perfectly decent CATL B-grade...

Has anyone installed their inverter and battery in their bedroom?
@MuddySkipper garden office is a whole different beast — mine's in the static and I ran the Fogstar batteries outside in a vented box because frankly I didn't fancy sleeping next to 200Ah of...

Smart Battery Sense temperature reporting in VRM portal issue
@GrumpyBuilder the Bluetooth sync dropout is the bane of my existence — my Smart Battery Sense in the static caravan does the same thing whenever my neighbour's dog presumably sits on the WiFi...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
My static van runs a chest freezer off a 200Ah Fogstar Drift and it's fine overnight — but ambient temperature is the wildcard nobody's flagging here; stick that freezer in a hot garden office in...

AC-coupled PV inverter total yield reported 1000x too low via SunSpec (AEG AS-IC02-4000-2)
Had this exact saga with my static caravan setup — Cerbo thought my panels had generated enough to power a particularly optimistic LED bulb, turns out WH_SF was sat at -3 when it should've been 0,...

Swapped out the old Victron MPPT on the narrowboat – few questions about the new settings
Got a 100/30 on my static caravan and honestly the absorption voltage setting is the one that'll catch you out — lithiums and lead-acid want completely different numbers and the Victron app will...

Connecting Vebus bms and Cerbo to 800va multiplus with only one vebus port
@Drift_Geek daisy-chaining through the BMS's pass-through port is exactly how mine's wired in the static van — Cerbo picks up everything through there no bother, took me longer to find a parking...

Bilge pump keeps tripping the fuse on my narrowboat – 12v wiring issue?
@Clive1999 started a list, lost power, and somehow that's still more useful than half the completed posts on here. For what it's worth from someone who's had a static van, a garden office, and a...

Help with Victron Quattro integration with 3 x Pylontech Fidus Plus 16KWh
@GrumpyDrifter your post got cut off mate, we're all hanging here like a bad cliffhanger on EastEnders 😂 For what it's worth I've got a similar static caravan situation — Victron MultiPlus-II...

OpenEVSE - solar charging or battery limit charging
@AngliaOffGrid ran into exactly this with my static caravan setup — OpenEVSE's battery limit charging mode was the bit that actually clicked for me once I stopped faffing with solar-following...
