MPPT converter, on/off the grid AC injector desing theory/practice?

[lightman]

Hello Dave.
I have been following you for about a year after I found one of your fantastic reviews!, and endup watching everything you have done.

I am dealing with solar panels for my first time and found out about your experience, but you used off the shelf, sunnyboy "black box" which is impossible here to buy because of regulations and ridiculous costs!, here a sunnyboy like the one you have costs half of what costs a small flat! insane!.

what about doing some video about inverters to inject power to the AC power grid?, how to handle phasing, over current, power outages!, how to go on/off the grid when mains goes out and come back.

I know you probably don't have many outages in you area, but here is very frequent, and sometimes quite long.

Also how MPPT converters works!, I mean, i know the theory but no idea how to desing one!.

I will love to see you addressing those points.

what do you think?
thank you
