@MickDavies good stuff. One thing nobody's mentioned yet — cable sizing. Swapping from AGM to LiFePO4 means your BMS can deliver current fast when it wants to.

Something nobody's mentioned yet — check your absorption time setting. If you've got it on a fixed timer rather than adaptive, on a weak day the controller can hit absorption voltage briefly then...

Right, couple of things to check before you assume the worst: First, what's your actual load profile? Fridge running? Phone charger left plugged in? Inverter in standby?

Right, before you start panicking, had this exact nonsense with mine two years back. Silent death, nothing on the display—proper maddening. Check your AC input breaker first.

Mate, the real question is your battery capacity more than the solar panels. 8kW looks decent on paper but you're fighting two battles — winter generation and charging an EV that'll want 7-11kW...

Proper welcome! Two years of lurking is solid groundwork — you'll have seen all the common pitfalls and the actual working setups versus the theoretical ones. Hybrid setups are where the real...

You've got a decent foundation with that 4kWp setup. The inrush current thing @RiverFinn and @WattAndrea flagged is real — I watched my battery voltage dip hard the first time I fired up a surface...

Depends massively on what "family" means to you, doesn't it? Got mates with three kids off-grid and it works a treat.

Outdoor wins for me. Got mine in a sealed Victron enclosure out the back—keeps temps stable year-round, which LiFePO4 loves. Indoor just eats into cabin space you don't have.
