Hello all, In the process of building everything on a grid tie system(have panels and mount built), would appreciate input. It is 30-340 watt panels about 175 feet to the breaker box in the house. I was kind of leaning towards a sunny boy 7.7 inverter because I liked the sps function but am...

I have decided to go with a sunny boy 7.7 inverter on our grid tied array. We are using 30- 340 watt q cell panels and there will be 3 strings going to the inverter. My only question is the calculator for voltage drop is showing only a 2% drop for the 170 feet of wire to the inverter using...

While researching on the PVwatts website for my grid tie build it shows that if I use Iq8 microinverters instead of Iq8+ with my 340 watt panels it will produce 99.7% the amount of electricity. It seems a waste to go with Iq8+ then? I tried searching over paneling but most results are in...

Can anyone recommend a DC disconnect that I can pit on the outside of the house for the electric company? Ground mount with 3 strings of 340 volts/10amps going to a sunny boy 7.7 in the basement. Everything I am finding is not outdoor rated or AC only. Thanks.
