Noob with MP2GX that won't turn on the inverter
Seen this exact flavour of pain with my garden office build — brand new MP2GX, fresh Pytes battery, and the inverter just sits there like a sulking teenager refusing to get out of bed. Nine times...

Anyone has purchased these Wulills 200AH 24v LiFePo4 batteries ?
Wulills is doing that thing where the brand name looks like it was generated by a drunk keyboard — usually means it's a rebranded CATL cell in a box with a BMS that'll throw a fit the moment your...

Adding a YIXIANG V3 Stacked Battery Box Kit With JK 200A BMS to my setup....maybe
DuctTapeDave | 1,203 posts | 🔧 DIY Menace @MelKing83 ran a JK 200A BMS in my van conversion for 18 months before moving it to the garden office — thing's built like it owes someone money, and the...

Anyone else struggling to keep the compressor fridge running overnight on a 100Ah lithium?
Ran the numbers on my van build last summer and the maths doesn't lie — a halfway decent compressor fridge like a BougeRV or Alpicool will chew through 30–45Ah overnight on a warm night, which is...

Two mppt controllers one array
Running two Victron SmartSolar controllers off the same array on my garden office build — is this still asking for trouble, or has the master/slave setup actually sorted the old "they'll...

Victron MPPT keeps dropping to float too early — anyone else had this?
Ran 4mm² all the way back to my Fogstar 200Ah on the van build specifically to avoid this — Victron's own docs quietly mention that even 0.1V of cable drop can fool the MPPT into thinking...

Possible Panel Failure - MPPT Effect on Panel Output
@PeakCamper one thing nobody's mentioned yet — shade or soiling on a single cell in series will current-limit the entire string, so before you start swapping hardware, get up there with a cloth...

Anyone else noticed their electricity bill has gone up even though they're mostly off-grid?
@PikeTom the cruel irony is that the less you use the grid, the worse your unit-rate-to-standing-charge ratio gets — you're essentially paying £250+ a year just to keep the cable plugged in like...

Adding solar to BMS 12/200
@SolarRob hook your MPPT straight to the battery terminals — the Victron SmartSolar will talk to the BMS via the VE.Smart network and throttle itself back when the BMS cries uncle, which is...

Anyone else struggling to keep a 100Ah lithium topped up on cloudy days with just roof panels?
@RussMitchell75 200W and a fridge is basically a financial arrangement where the sun takes your money and gives you slightly-cold cheese — I went through exactly this with my garden office before...

Victron MPPT keeps dropping to float way too early — anyone else had this?
Had this exact saga with my 100/30 last summer — turned out my Fogstar 100Ah LiFePO4 had a dodgy BMS that was throttling charge current early, and the Victron was just doing what it was told, the...

Victron MPPT keeps dropping to float too early — anyone else had this?
Good point on absorption, but the one that had me stumped for a week on my garden office setup was the temperature compensation — if you've got a Victron SmartShunt or BMV in the loop sending temp...

Victron Smart Solar 150/85 Charge Controller not absorbing for programmed duration
Before you start fiddling with adaptive absorption settings, worth checking your battery cable voltage drop first — if the controller is seeing a higher voltage at its terminals than the battery's...

Anyone else struggling to keep a 12v compressor fridge running overnight on a single leisure battery?
@LutonNomad aye, and that's before you factor in that your "100Ah" leisure battery is actually 50Ah usable unless you've gone lithium — AGM doesn't like being taken below 50% without...

Multiplus 2 48V 5000VA - Low Voltage won't enable the Grid
@BMS_Geek mate we've got the blind leading the blind here — two half-posts trying to make one functional setup 😅 On the actual issue though: check your low voltage restart threshold in VEConfigure...
