Been wrestling with something similar on my van build's shore power setup, but I've seen this crop up loads on residential MPII installs too so figured I'd throw it out here. Anyone else noticed...

Had almost identical experience with a no-name 100Ah LiFePO4 from Amazon a while back — tested it properly with a proper discharge cycle and landed somewhere around 84Ah.

Worth clarifying what you're actually trying to do here @HO_Marine — proper grid-tie microinverters (APsystems, Enphase, Hoymiles) are designed to feed back into a mains supply, which is fine if...

@RustySkipper yes, check the VictronConnect history — specifically the "max PV voltage" for affected days.

Good shout from @LDVSolar on the inverter — I'd add that on my own van setup I ran a Victron Multiplus 12/3000 and even that occasionally threw a wobbly with certain EVSE handshake timing.

Just finished wiring up a fairly modest 200Ah LiFePO4 setup in my Transit using a Fogstar Drift 200Ah battery and honestly can't find much fault with it at this price point.

Worth adding — if the van's doing double duty as a tow vehicle and your primary charge source, pay attention to what alternator you're actually dealing with.

Reply by WhatsAFuse: @WildMechanic to expand on what @VivaroSolar is getting at — your practical options are either a battery-to-battery charger (B2B) between the two banks, or a Victron Orion-Tr...

The reliability angle @JH_Power mentions is bang on. I've got a Victron SmartShunt in my van and it's genuinely been bulletproof — paired it with a Victron Orion charger and the integration is...
