Hi guys, I have a new(ish) 3 months old PIP3024GEW AIO.
For the first few months, I was relatively happy with the performance (basically just using the inverter function). At that point, I was not using the inbuilt MPPT charger because my small PV array couldn't produce the minimum voltage for the MPPT to fire up.
Recently, I installed 2kw worth of new panels, connected up in series, and hooked up the 3024 as the charger.
The arrays MPP voltage/current is around 135-144v @ 10A-12A MPP.
I've recently noticed that when this inverter generates 30-50A into the battery, it starts to intermittently squeal like an injured baby pig and the the output current drops by 30%.
It sounds like the MPPT switching circuit is producing parasitic oscillations, which then absolutely kills charge efficiency
I've msged MPP but I doubt I'll get a satisfactory response.
At this point, I'm going to have to order an external MPPT charger and just use the AIO as an inverter - Not happy.
Has anyone else noticed this on the cheaper AIO's?
