Likely ok, but maybe not, to use wood to build a 48v server battery rack? Using 3 eco-worthy cubix.
Wood's a bit of a grey area for this tbh. Technically it's not conductive so you won't get shorts, but it does burn — and with 48v lifepo4 that's not nothing if something goes wrong with the BMS...

Scheduled Charge - system begins discharging immediately afterwards SoC hits 100%
@DalesOffGrid had almost the exact same issue with my Fogstar setup before I sorted the comms. The Cerbo's basically flying blind on SoC, so when your scheduled charge ends it just sees voltage...

if you require 12V/24V lithium ion solar battery casing to do your battery pack, i can help you
Agree with all the above — also want to know about IP rating. Running a pack outdoors or in a damp environment (mine's in an outbuilding) means ingress protection isn't optional really. Also...

Anyone else struggled fitting a 100Ah lithium under the bed in a Transit base?
Had the exact same drama with my setup mate. Spent ages convinced I could squeeze a battery in somewhere it physically couldn't go — turns out foam insulation adds about 25-30mm you never account...

Anyone else using a Raspberry Pi to log their battery data, or is there a simpler way?
@BoxerWanderer yeah the SD card thing is a rite of passage innit 😅 switched to a proper USB SSD boot drive on mine and never looked back — SD cards and 24/7 write cycles just don't mix Running...

Anyone know if a 200Ah lithium battery will handle a small chest freezer overnight?
@RetiredNurse49 makes a solid point on usable capacity — worth adding that with a single 200Ah LiFePO4 you're looking at roughly 160–180Ah usable depending on your BMS cutoff. Quick real-world...

Removing the battery for an Emergency?
Been thinking about this after a mate of mine had his LiFePO4 pack fail completely last winter — dead cells, BMS locked out, nothing.

Growatt MIN 4200TL-XH AC-coupling with MultiPlus-II 48/6500 ESS during grid outage
The frequency shifting is the key bit here — MultiPlus-II will push frequency up toward 52Hz when the batteries are full to throttle the Growatt back.

ECGSOLAX 7KW Hybrid Solar Inverter $535 AeternaSol 200W 18B N-Type Bifacial Solar Panel $71
Agree with both of you on the inverter — at 7kW you're talking serious money if it goes wrong. Had a cheap no-name unit fail on me a couple of years back and the support was basically...

Victron Multiplus keeps switching to passthrough at night — anyone else had this?
@SueParker64 classic one this — worth checking your AC input current limit setting in VEConfig. If it's set too low the Multi will just hand off to shore power rather than inverting. Also check...

Anyone else using a Raspberry Pi to monitor their Victron system, or is there a better option these days?
Still running a Pi 3B+ here with Venus OS and it's been solid for nearly 3 years. Wouldn't swap it out unless it died tbh. One thing worth adding — the VRM portal integration is the real win for...

Swapped to a 200Ah Fogstar Drift LiFePO4 last month — here's what surprised me
@ValleyOffGrid the usable capacity jump is the thing that gets people — you've basically doubled your real-world storage without adding a single cell 😄 One thing that caught me out with my Fogstar...

Anyone else had issues with Victron MultiPlus-II tripping on high loads?
Running a MultiPlus-II 48/3000 with a 16kWh Fogstar Drift LiFePO4 bank and it keeps tripping when I fire up my workshop compressor (about 2.2kW startup surge).

Generator für Inselanlage
Been running a Fogstar Drift 200Ah bank in my shed setup for about 18 months now. For backup charging I went with a Yamaha EF2200iS — bit cheaper than the Honda but still inverter-type so the...

Picked up a 200W panel from Facebook Marketplace for £40 — worth it or dodgy?
Good score at that price if it checks out. One thing nobody's mentioned yet — check for microcracks.
