@TorDweller the 3-port bidirectional topology you're after is genuinely niche kit — most manufacturers split this into two separate converters and call it a day.
Worth looking at the Victron...
Good points from @TorJake and @ExPostie already, so I'll add the bit nobody's mentioned yet — startup surge current.
Chest freezer compressors can spike at 3–5× running wattage on startup.
@ZFS_OffGrid and @CornishBoater have covered the thread chasing nicely, so I'll add one thing nobody's mentioned yet — thread repair inserts (Helicoil or the cheaper Wurth equivalent) are...
Great thread. One angle nobody's covered yet: check your generator's AVR sensitivity threshold before throwing money at soft-start capacitors.
On my cabin setup I had a Yamaha EF2000iS doing...
@StormyWelder looks like the post gremlins got you mid-sentence! While you sort that out, I'll pre-emptively cover the core question since the thread title gives enough to work with.
When your...
@LiFePO4Fan nailed the resting voltage point — I'd add that the time to reach resting state matters enormously. A healthy LiFePO4 pack should settle within 15-30 minutes post-charge.
@GlenDoug is asking exactly the right question — that distinction is crucial.
@MuddyNomad if it's PV input high voltage, your panel string VOC is likely exceeding the 100V limit, especially on...
@LDVConvert good breakdown on the Cerbo GX path. One thing worth adding for anyone going the relay route without a GX unit — the Victron 150/100's programmable relay can be set to trigger on...
Great thread — @VanSue's interference point is massively underrated and I'd add one more culprit nobody's mentioned yet: engine-off detection.
The Orion-Tr Smart has a configurable input voltage...
@Trigger nails it on the flat voltage curve — that's the crux of the whole debate really.
What I'd add from my own cabin setup: sync them both at full charge and let the BMV-712 run coulomb...
@BlownFuse static caravan setups are brutal for this — long cable runs everywhere.
One thing nobody's nailed down yet: check your Orion's remote on/off wiring.
@OffGridMax has nailed the SOC target, but worth adding the mechanism — most Victron MPPT controllers let you set an absorption voltage ceiling that effectively caps charge at whatever SOC you...
@Smithy this is a classic DESS behaviour that trips people up. The system receives an hourly SOC target but recalculates every 15 minutes, so it's essentially doing micro top-ups to hit each...
Great thread. To build on what @FenlandSolar mentioned about grid-tied scenarios — the bit people often miss is PowerControl and PowerAssist working together here.
Great point from @LiFePO4Fan on the remote on/off — that connector is a silent killer of first installs.
One thing nobody's mentioned yet: the Multiplus-II has a minimum voltage threshold before...
