I've had a solar system with a Sunny Boy inverter for ten years.  I've just been told by a salesman that Sunny Boys are not reliable and that we are lucky that it has survived this long - is this true - are Sunny Boy inverters unreliable?

Is his quote of £21,000 for another 16 panels, 2 Solar Edge inverters and a Powerwall 2 reasonable?

I'm overwhelmed by numbers!
