I’m a former roofer now insurance adjuster. I get on over 500 roofs a year. Pipe boots work when correctly installed and maintained. I get on roofs that have the rubber portion worn off due to age and wear all the time. Also, installing it correctly is the key. I think the boxes are much...
None of this is my setup. I didn’t have rails in this area (SnapNrack top speed) and the entire wire went into house and down into inverters from the string.
I used the EZ Solar JB Rooftop options... yes the price sucks, but you need to make sure this is water tight... I wouldnt rig something up with the pipe flashing unless you know exactly what you're doing. The EZ box fit perfectly under my panels and was pretty easy to install.
Smart panel like SPAN but without the required preferred vendor install. 40 spots instead of 32. Built in EMP/Surge. Talks to EG4 inverters, Ethernet/wifi, app works on local network if internet down.
I’m an insurance adjuster, former roofer and DIY solar install on my house. I would strongly advise you have the roofing company coordinate with installers for the panels. There’s a chance the roofers could set the flashing as they install the shingles making the rails much easier to install...
Yeah... I installed 2 EG4 18kpv and I wired them like this:
Meter into outside shut offs (200amp x2)...
Shutoffs into each EG4 Grid input
From Inverter load to a 400amp fused disconnected (has two inputs on each side of pull)
From disconnect into electrical panels
This allows both inverters...
Yes, similar to a small server or gaming GPUs x2. Everyone in my family has asked "whats that sound" when i have the storage room door opens. The fans stay silent as long as its under 6kw per inverter.
Oh one more note - the west facing slope with no panels is a 10/12 pitch, 2+ story high and has a pipe jack dead center... I did consider panels but it would have been extremally difficult to get anymore than 6 installed.
All these are great points that i considered in length prior to install. Currently we have full sun and the panels with the shadow are averaging 270w per panel (8 panel). The string of 13 next to it is avg 330w. While it does hurt the output overall i considered this and added 4 additional...
I have the panels that are hit by the shadow on their own string... the top row and left side are on their own string... this helps isolate the shadow panels... In the summer time this shadow is pretty much gone
I dont get anywhere near the 27KW rating since i have east/south/west facing... right now with bad sun angles i get 12-14kw during peak...but this design allows an even production throughout day.
