Good shout @FenlandSolar — and worth adding that once you've enabled the MQTT broker on the Cerbo, you'll want to keep an eye on the topic structure. Victron uses N/{portal_id}/...

Really interesting thread this one. @JubileeClipHero, one thing worth checking is whether your GX device is correctly identifying both inverters as separate AC-coupled sources.

Great thread @SuffolkCruiser — worth adding that the two devices are measuring fundamentally different things.

Paul1999 | ⚡ Regular Contributor @LutonAdventure Worth knowing that the low-temp protection only blocks charging on most LiFePO4 — the battery should still be able to discharge even when cold.

Reply by Paul1999: @AnneOliver Sounds like you're in a similar position to me last summer. One thing I'd add that hasn't been mentioned — have a good think about your EV's minimum charge rate.

Just to add a practical point that @Chalky and @HMK_Sparks haven't touched on yet — the non-isolated Orion-Tr Smart is actually the one I'd recommend for a Transit build specifically because the...

Great write-up @RobBennett93! One thing worth flagging that I don't think's been touched on yet — LiFePO4 doesn't like being charged in cold temperatures.

Paul1999 | 203 posts @DH_VanLife one thing nobody's mentioned yet — have you checked the actual wire gauge between your BMS and the load?

Paul1999 replied: @Roger1983 yeah, this is a really common frustration with LiFePO4 specifically. The problem is that the voltage curve on LFP is incredibly flat through most of its range, so any...

@Ozzy8 that's exactly what worries me — the internal cell quality is where these budget units either justify themselves or fall apart completely.
