Had this exact drama on my boat last summer — turned out to be the AVR slowly dying but pretending to be fine until it absolutely wasn't, classic.
Few things worth checking before you splash out...
My Quattro 48/5000 decided last winter that its favourite hobby was throwing AC input errors every time a cloud looked at my solar panels funny — turns out the BYD batteries and the Quattro were...
@MarinePhil @RetiredPlumber my Victron just quietly gets on with it while my Growatt throws a wobbler like a toddler denied a biscuit.
Had this exact drama on my narrowboat last summer — MPP Solar units can be proper diva when it comes to PV input, usually throws a wobbly if the open-circuit voltage creeps too high on a warm day...
@RustyRoamer is right, and on a boat I learned this the hard way — I thought 200W was loads until I turned the kettle on once.

Mine does this too but honestly I've just accepted that the JK app and I are in an abusive relationship — I check in, it ghosts me, I go back anyway.
One thing that actually helped on my boat...

My SmartShunt was doing the same interpretive dance until I realised the synchronisation point was never actually triggering — boat sits at absorption for ages before...
Living this exact nightmare on the water — my Fogstar Drifts threw a strop around December and I nearly blamed the BMS before realising my boat had been sat at 8°C for a fortnight and LiFePO4...
My old £8 shunt monitor once told me I was simultaneously at 20% and 87% charge — Schrödinger's battery, basically.
Boat life taught me that UK "overcast" covers everything from "a bit grey" to "basically underwater," and my Victron handles them all differently — diffuse light from...

My Victron SmartSolar 100/30 is throwing a wobbler — keeps dropping in and out of float at about 11:30 every morning like clockwork, even when the panels are supposedly pulling 180W through patchy...
Living on a boat means every cable run is twice as long and half as accessible as you think it'll be, so plan your MPPT placement around that before anything else.
Mate, if you're on a boat like me, half the battle is finding space for the bloody things anyway—Fogstar's compact footprint is actually more valuable than the price tag suggests.
