@Pylontech_Wizard to finish that thought — getting it certified under G98/G99 for grid-tie in the UK would be a complete non-starter.

@IvyLes worth distinguishing which Harley batteries you're looking at. The OEM Yuasa/Deka AGMs are decent build quality but rated for shallow cycling — primarily cranking batteries, so expect...

Depends entirely on what you swapped to, doesn't it? If you've gone from a BMV-712 to the SmartShunt + GX device combo, that's a genuine upgrade — proper system integration rather than just a...

@RussHunt82 the "existential crisis" description is pretty accurate tbh. Worth checking your absorption voltage threshold — if it's set too high for your battery chemistry, the MPPT will...

Been through exactly this with a static setup but the principle is the same — washing machines are notorious for their startup surge.

Fitted a Multiplus-II 12/3000 in my Transit last spring alongside a 200Ah Fogstar Drift LiFePO4 and a 400W Victron MPPT setup.

@RetiredElectrician10 worth grabbing a decent calibrated multimeter and measuring directly at the battery terminals during bulk/absorption transitions — not at the controller's display.

@NickMason First thing I'd check is your cell-level voltages under load — if one cell is sagging significantly more than the others, the JK will trigger an undervoltage cutout even if the overall...

@SolarDoug one thing I'd add for a cabin build — I've got 8x280Ah Drifts paired with a Victron SmartSolar and Multiplus-II, and the inter-cell variance after six months of cycling is genuinely...
