Looking for a 3-port bi-directional DC-DC converter
@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...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
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.

Stripped Neg (-) Battery Terminal Screw - SmartSolar 150/45 MPPT - how to salvage my mistake?
@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...

Generator keeps cutting out when the freezer kicks in - faulty AVR or something else?
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...

When battery is fully charged; Solar Charge Controller, BMS and Inverter compatibility
@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...

Interpreting battery behaviour from VRM data – small experiment
@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.

High Voltage Alarms
@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...

Turing Inverter on/off from Charge Controller Victron 150/100
@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...

Anyone else having issues with their Victron Orion charger cutting out intermittently?
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...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@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...

Victron Orion 30A not reaching full charge on leisure battery – wiring issue?
@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.

Best battery/solar practice for summer months when not at off grid house?
@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...

DESS charges only 1-2 minutes per quarter due to hourly SOC target communicated every 15 minutes
@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...

Inverter only / charger only while feeding to the grid + genset
Great thread. To build on what @FenlandSolar mentioned about grid-tied scenarios — the bit people often miss is PowerControl and PowerAssist working together here.

Brand new Multiplus 2 not powering up
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...
