Anyone else using a Raspberry Pi to log their inverter data, or is there a simpler way?
@AnneOliver honestly don't put it off too long — the learning curve looks steeper than it actually is. If you've already got the Multiplus II, you're halfway there.

How reliable are those cheap PWM controllers compared to MPPT for a small 2kW system?
Cheers for sharing that, @QuietTrekker. Yeah, PWM's rough on smaller systems where you're counting every watt.
