There is a 200A panel with 60 and 80A breakers and then a switch blade ac disconnect before this combination unit. The wires coming in the right are from the disconnect for solar. The wires going out the bottom go so a 200A panel in the basement. It has not been inspected yet and solar has...

The power company installs a bydirectional meter.

Yes the buses inside the meter. It The bus is inside of the meter. It is put together with bus bars, so there is no wire to tap into prior to the main disconnect. The disconnect is a Requirement for the photovoltaic system. The 2 inverters need current protection. That is why I have a 60...

My crude drawing of my idea.

My thought is that the main combo meter could not have more than 200 amps going through the bus bar Because the inside 200 amp sub panel Would trip. The main panel would either be drawing from the grid or solar production would be back feed to the grid.

Yes it will be a sixty and eighty amp breaker for pv. They would be in the 200A combination meter/ panel (225a busbar) With a feed through lug powering a two hundred Amp panel inside the home which used to be the main panel. With that set up the combination Meter breaker box would be...

Correct, I currently have a 200A panel that is rather full with meter only. Electrician said I can feed the 200A panel presently in place from a new combination unit but I am not sure on his plan on how to do this and want to avoid any issues (electricians in my area are unfamiliar with solar)...

Most inverters companies have software that you can can input your data into that will give you the data you need based on high and low temperatures as well as angles and directions of the panels.

If I have a 200 amp combination meter panel, can I just put two solar breakers in it and then feed my interior 200 amp panel with it? The solar breakers can not be placed in the interior panel because of the 120% rule. My concern is overloading the busbar. The Combination meter busbar is...

Any thoughts on this?

I have two inverters that I want to tie into the grid. A 10kw and a 15kw. My original thought would be to go from the inverters to an 80A and 60A circuit break in a stand along panel box. From there I would go to a disconnect where I would do a line side tap before connecting to the meter. I...

I am using q cell 480w bifacial panels (xl-g1033 / bfg). They have a Voc of 53.39 and Isc of 11.12 (hope I am using the correct numbers for my calculations.) I plan on having 1 string of 12 and one string of 13 both in series which will go to a Fronius 12.5kw inverter. My historical max temp...

What I was thinking is a fused ac disconect. If I do that, I should not need any other components. The inverter does not need any dc fuses or breakers.

So I could run each inverters to their own 80A breaker then the panel to a ac disconnect near our meter before a line side connection? I am asking because I was told I could not but did not understand why. So maybe they were wrong
