Solax or other.

2 of the 3 quotes I've had so far for PV have recommended Solax with a 20y insurance backed warranty.

I believe these aren't classed as premium drives (for whatever reason) such as SMA and ABB.

Can the premium cost be justified?

Thanks.

other if you have any shading

Solaredge? I haven't seen any shading but that might change in the winter with the lower sun and trees in close proximity.

But that puts the 5kW out of reach unfortunately It's an extra £900. I could afford the optimised 4kW though.

The optimised systems seemed to get a mixed review regarding more to go wrong and payback times.

I don't know ether way, I know very little regarding PV.

SMA or ABB have shading functions that work very well in shading, I've seen the solax inverters struggle / get stuck on a false voltage peak just from early morning shading as the sun comes around onto the panels.
