The roof penetration and all interior runs must be metal, not plastic to meet code, that why I and others use the higher dollar box with flashing for zero leaks and emt stub thru the roof.

I used THIS (Quick Mount PV QMQB-J1-B) which appears to have been replaced be THIS

Using the phone app connect to the inverter and settings -> Work Mode selected Feed in Priority Mode, select enable and then setup the Time of use for discharge window and the current you want.

Current install is homeline split panel bus with plug-on neutral ( my house ) which replace the zinsco that came with the home and the cost was half of QO from the box store. I have done extensive work with QO for commercial locations, great product and more compact but not on my dime.

Just for informational purposes, Solis has single unit string inverters that go up to 350Kw a unit, very compact and have all the features for remote monitoring and control. You want to have a distributed architecture not a single point of failure and these large units are used in solar farms in...

Solis is the third largest solar inverter manufacture in the world, and the S6 it isn't a copy of anything. For systems below ~20kWh of storage, even with the higher cost per kw of storage, it is lower cost than eg418k or Sol-Ark 15K as right off the bat the inverter is 5K lower cost and then...

Call and make an appointment with the permit reviewer, they work for you on your tax dollars, be polite and professional but NOT scared to question what they say. Your PE that stamped the plans should be able to help as well as they should know the Florida building codes.

Done it three times You need PE stamped plans showing single line drawing, all data sheets for racking and components , letter the roof and trusses have been reviewed for wind code compliance and approved. A firm like Green Lancer can do all this for a reasonable fee..

This seems a misunderstanding of the statutes ( really English ) as this paragraph is not new and I have pulled permits in 2020 that the statutes had the same language in Pinellas county. ( I looked up the 2019 version and it has the same language ) The section 3 you have listed is a single...

It is part of NEC2020 code which Georgia adopted so you have to have UL9540 listed for battery backup

NEC2020 requires UL9540 listed ESS systems ( paired inverter and battery ) no other ( legal ) options, which GA is one of: https://www.nfpa.org/education-and-research/electrical/nec-enforcement-maps

This ^^^^ If you are the homeowner, you can do any permitted work in Florida, you just can't do this for others, that requires licensed contractors for specific trades. I have in 3 properties in the years built large solar systems including building a net-zero energy home subbing out trades I...

The wattage you have is for AC loads , but the energy comes from the DC batteries. Ohms law is Power = Volts * Amps, so one takes your wattage and divides by the battery voltage of 12 volts to get the 550 amps and that's not taking into account efficiency losses. Read up Here for more details

They were ~$380 each just over a week ago on FleaBay ( DC house were ~$360 same time ). Eco-worthy has new sales every week, so pays to wait
