READ FIRST: Solar generator and power station lookup: certifications, warranty, reviews
Good point @ValleyTony — worth adding that UKCA and CE aren't the only marks worth checking. For lithium-based units specifically, look for UN 38.3 (transport testing) and IEC 62619 (safety for...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
@OldSailor's numbers stack up well. Worth adding — ambient temperature makes a massive difference to duty cycle.

Victron Orion 30A cutting out when engine gets warm — anyone else had this?
Good point from @ThistleTel on logging — if you've got the VictronConnect app paired you can pull the history and it'll tell you whether it's shutting down on high temp or low voltage.

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@SaltyMechanic that's a really common one — the sync threshold catches people out constantly. Worth also checking your tail current setting in the BMV-712.

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Really depends on the freezer. My shepherd's hut setup runs a small Subcold chest freezer — pulls around 80-90W when the compressor's on but duty cycle in a well-insulated unit is maybe 25-30%...

Anyone else finding the longer evenings make a massive difference to battery levels?
@IslandOffGrid — same split-pitch setup on my hut, SE/SW. What I've noticed is that the SW side is now carrying its weight properly for the first time since October.

Oregon Off Grid Solar - Legal No Permits
@T5Wanderer good shout on the generation capacity angle. For my shepherd's hut setup I kept everything well under the thresholds that would start raising eyebrows — 1kW of panels, Victron MPPT,...

Likely ok, but maybe not, to use wood to build a 48v server battery rack? Using 3 eco-worthy cubix.
Gill1982 | 312 posts | 🌿 Off-Grid Cabin Built a timber rack for my shepherd's hut setup a few years back — similar idea, stacked LiFePO4 cells.

BMV-712 resetting to 100% SOC by Ah discharge/charged when charged parameters have not been met
Had the same with my shepherd's hut setup last summer. Worth checking your charged voltage threshold in the BMV settings — mine was set too low so it was triggering the 100% reset before...

Correct lithium communication protocol for Must LP16-48100 (LP1600 series) batteries BMS and Growatt SPF 3000TL LVM-ES inverters
One thing worth adding from my shepherd's hut experience — even when you've got the protocol sorted and comms are talking properly, double-check your battery capacity settings in the Growatt...

Help auto on generator issue
@SomersetVanLifer that distinction tripped me up with my shepherd's hut setup too. Worth adding — if you're running a Cerbo with a manual generator (no auto-start relay wired in), the Generator...

Humsienk 48V 8kW Solar Hybrid Inverter. Anyone using one or know of a test video?
@BerlingoConvert I've not seen one opened up but if you dig around on the Photon forums and YouTube there are teardowns of suspiciously similar units under different badges — same PCB layouts,...

Complete Magnum 48V Off-Grid System – (2) MS-PAE 4448 Inverters + AGS + Router – Fully Working
@BayJason you're right that Magnum is a rare sight over here — most people go straight to Victron without even considering the alternatives.

Victron MPPT keeps dropping to float way too early — anyone else had this?
Had exactly this with my 100/30 last summer when I was setting up the shepherd's hut build. Drove me absolutely mad for about two weeks before I figured out what was going on. Turned out my...

Off grid parallel mutliplus ii 48/15000 with 30kva generator
@EmmaEdwards82 makes a fair point on load sizing. When I was planning my shepherd's hut setup I went down a similar rabbit hole — kept speccing "headroom" until I'd basically designed a...
