first time diy. no electricity experience

They are not generating what i hoped the two home made ones generate 8.5 amps combined tops i think. Old cells .

Is it ok to connect all 3 panels together going to the mppt even though they renogy panel is wayy diffrent than my 2 homemade ones?

so NO grounding rods for me?

Im lost in the safety off all this.

What do the rods do?

You have a whole lot more than safety issues. Sorry I cannot help you.

Well i know the rods ground stuff but do i run the bare copper wire underground all the way to the shed where the mppt and other stuff is?

The rule is, panels of similar Imp may be connected in series; panels of similar Vmp may be connected in parallel.

I thought your panels used 3" X 6" cells, which peak about 4A, so 2 in parallel might do 8A. I would run a load test
on the home home brew panels to check for any weak spots. If you have good sun measure the shorted current.
Then using ohms law construct a dummy load drawing near half that current at 80% of Vmp. When connected
with the same sun, voltage across the dummy load should head toward 80% or 90% of V open circuit. If its
much less, there may be faults, like weak cells or connections.

65', check your line losses. These will have a big impact on optimizing delivered energy. Bruce Roe

Yes there are weak link but im not too worried about that right now. What i do need to know is how do i ground my electronic equipment in the shed. Also im looking into getting nickel iron batteries.

..... im looking into getting nickel iron batteries.

Nope, hold off till you have gone through a cheap set of lead acid batteries. For NiFe battteries, you need 2x the capacity, a 200ah bank should scale up to a 400ah NiFe bank to account for the internal resistance.

= PNPmacnab] $15 for the basic MPPT controller electronics that is all home built.

Wow, got any details on that you could share

You know better than that Mike, PNPmacnab is a fraud. He will come back and tell you he built it to use his 1200 watt homemade panel on a car battery.

Can I wire this wind turbine kit in with my existing 2 homemade panels that get 36v combined at full sun ? Just something to play around with
