So after running into a roadblock with my 18kpv and backup plans with my utility (they require a separate production meter) Ive decided to go net metering only for now. Im gonna try to find two sunny boy 7.0 inverters (unfortunately just discontinued). They said I could keep my old plan and add...

My utility is well known for really disliking net metering. Several installers in the area have told me they make it difficult on purpose. Anyway they have put my project on hold. The second paragraph is easy for me to refute. The inverter is UL1741SA compliant. I don’t need an auto...

I know this has been discussed here, but I think my situation is a little different. My meter and main breaker are one box attached to a shed 40' from the house. The Breaker at the meter has a ground rod and appears to be bonded to the neutral (like the diagram below says to do) but from there...

I got this https://www.homedepot.com/p/Siemens-200-Amp-2-Pole-3-Wire-General-Duty-Fused-Outdoor-GF224NR/302352591 200a fused disconnect that goes between my feeder tap and my inverter. There are two poles for the hot wires and a ground bar. What do I do with neutral? does it just pass through...

I've got 60 300w panels I'm trying to fit in my 18kpv. This is the best I could come up with. This is my first system, I would appreciate some double checking. Im mainly concerned about my plan for mppt1. 2 and 3 look plenty good I think. Thanks! string plan for 60 panels and EG4 18kpv Panel...

I had planned on doing the partial home backup with a 70a back feed breaker As detailed in the diagram. Signature solar told me I wouldn’t get my max back feed amount with this setup. upon looking into it further it seems the 18kpv max backfeed is 50a? So it seems to me like the backfeed breaker...

Did your buttons come installed? Are they just in a bag I can’t find? Also, getting those covers off was absurd. It took me 15 different screwdrivers and I had to eventually grind one down to fit. Even then one was stripped to begin with and I had to drill it out. But ya anyway, where are my...

Can someone help me to understand this? This EG4 diagram says I need a 2 pole disconnect between my main panel and inverter. So cant I just shut off the connection either through the 70 amp breaker in the main panel, or I can just do the inverter shutdown? Why do I need a switch between them...

hi everyone, great forum you have here. First, my powerpro battery didnt come with the lifting handle (that was fun unpacking), or manual, but i found the manual pdf on the sig solar site. what I cant find is what height to install the 18kpv bracket in order to put the battery and conduit box...
