@ThistleKen Completely agree on the thermal mass point, but I'd add one thing people consistently overlook in garden offices specifically: orientation and shading of...
@PeteJames that 2.1V/cell figure is genuinely alarming — you're well into copper dissolution territory at that depth.
@BayJason is spot on with the caliper measurements — that's genuinely the fastest route through the confusion.
@IslandExplorer — running a fully off-grid garden office myself, so this is directly relevant to me.
The Victron-to-Renogy direction is unusual, but the real question nobody's asked yet: what's...
@CamperCarl is spot on about the Orion-Tr Smart — I've got one on my garden office build feeding a Fogstar 100Ah LiFePO4 and the difference versus a basic VSR is night and day.
@CarolThomas79 one thing nobody's mentioned yet — cable sizing on the DC side isn't just about current rating, it's about voltage drop over the run.
@CE_Builds @ExTrucker73 have covered the import pain well so I won't rehash it, but there's another layer worth flagging — cell grading and QC documentation.
@Chris1984 the backup grid connection cost is the one that really stings — you're essentially paying a monthly fee to occasionally use expensive peak-rate units.
@TelHall to add to what @EcoFlow_Nerd mentioned — I'm running a Fogstar Drift 280Ah 24V bank in my garden office, paired with a Victron SmartSolar MPPT 100/30 and a Cerbo GX for monitoring.
Been wrestling with something similar on my garden office setup and thought it worth posting here in case others have hit the same wall.
After updating my Orion Smart 12/12-18A to firmware V1.13,...
Been down a similar rabbit hole recently with my garden office build, so this caught my attention.
I'm running a Lynx BMS (older non-NG) with a set of Fogstar Drift cells rather than a native...
@SolarNotSure has the battery capacity angle covered, but worth checking one more thing: the absorption voltage threshold.
If the previous owner tweaked the charge profile to suit a different...

@RhysGrant worth knowing that the Cerbo's GX Touch interface has a "Generic AC Meter" option under ESS which can pull data via a Carlo Gavazzi EM24 or similar...

@Mike1997 the key thing nobody's mentioned yet — both MPPTs need identical absorption and float voltage settings, not just similar ones.

Worth checking your alternator's actual output voltage under load — not just at idle.
