Duke Energy SC - New rates for grid tied export

[Zwy]

Can you explain that a little more?

You have 200A service coming into your meter, then from the meter to a transfer switch. The switch can transfer from the meter service to the inverter/solar/battery service. So, the "out" from your inverter goes into the gen terminal on the transfer switch. The shore terminal on the transfer switch is the 200A service.

If that's all right, how do you charge the batteries from utility? You basically have the inverter "inline" in that configuration, right?

I can't really transfer circuits around, my meter base is ~200 feet from my breaker panels, so I would prefer this to be a "whole house" configuration and tie in right after the meter.

You will need a master breaker panel and a loads panel.

This is how mine is installed. https://diysolarforum.com/threads/e...s-diagram-correct-you-asked.56258/post-732148

If you want to tie in 200 feet away, it will get costly for wire as it would require twice the wire to be able to switch the transfer switch between grid power and inverter power.

I suggest adding another panel that is the loads panel, use your current breaker panel as the master panel. This wiring diagram is an example of how to wire in a 3 pole double throw transfer switch with a critical loads panel powered by grid or inverters. It would depend on how your inverter handles N-G bond that determines whether you need a 2 pole or 3 pole double throw switch.

10 position manual transfer switch is installed beside the main circuit breaker panel for the house. The installation of the manual transfer switch has you bring 10 circuits from the main box through the transfer switch and then back out to those loads. So, if the switches on the manual transfer switch are in the utility position, grid just passes through the transfer switch to the loads. Conversely, if the transfer switches are placed in the generator position, they take power from the other input to the transfer switch, solar system.
In my main panel I placed a 30 amp double pole breaker to feed the inverter AC input. So now my inverters have a battery input, a solar input, and an AC input from grid.
Inverter AC output is routed through a double pole 30 amp breaker to the generator input on the transfer switch.
All automatic switching is performed by the inverters based on settings in those inverters.
The only time I need to switch the manual transfer switch is for maintenance on circuits in the house.

You use a line side tap.

That’s what I was telling you earlier.

Just saw a new article that Enphase is having a big layoff. One of the factors they pointed to as causing the drop in demand is "metering reform". I have a feeling that's a coded way of saying exactly what we're talking about in this thread.

Incentives/subsidies change, it’s be best markets and industries plan around those incentives disappearing.

Solar+storage is the future, the price points today is the equivalent of net metering PV in early 2000s when net metering was coined.

Maybe more incentives for solar+storage is in order ?

Solar + storage kills much of the value of the electric company; net metering was bad, solar w/storage is "game over". At least in suburban/rural areas, cities, people living there have no way to get away from the utility, so, perhaps they will just focus their efforts (IE, price increases) there.

Incentives and subsidies is the government taking YOUR money and giving it to other people. Its not free.
