Can you just have a secondary system that you can plug into without tapping into the grid and avoid the charge?

Whether you have solar or not, some electric companies will charge you a standard amount if you don't go over a certain kWh per month.

Yeah but this is a specific “you have Solar so you have to pay us per kWh installed” not even just the minimum charge.

I agree. I was just responding to the comment that made it seem you can get out of paying electric companies some how. Which you can't.

Hmm. If you’re 100% self sufficient, what are they going to do if you don’t pay the fee? Disconnect you?

Yes, disconnect you. That fee is for the processor to remain connected while not using their utility

They are a business, they can lobby. Heck they may make it legal to send you to collections and ruin your credit. Who knows. The most important part is they do lobby to get laws passed that benefit their profit goals.

I think that’s more for people that generate a ton of extra and sell to the grid on sunny days but still need grid tie for night/clouds/etc so they can’t just straight disconnect.

Yes, some kind of battery storage system. But that's another pricey upfront cost.

Why do that? Just have an automatic transfer switch like people do with standby backup generators. When the solar stops producing, the panel automatically switches back to the grid. Then you only need enough batteries to last a few seconds at a time.

Depends on where you live but where I am doing that without approval of the utility is A BAD THING.

You can do it with their approval that is a proforma process provided you use one of their approved switches and it's installed by a certified electrician and a permit is pulled at city hall.

The reason and I agree since my father was an electrician is you don't want to back feed into the grid during an outage that is dangerous for the linesmen working the problem.

These days it's far too easy to buy a product online that has all the right stickers but isn't actually safe to use.

A transfer switch is designed to prevent this entirely though. Either your house is connected to the grid, or it's connected to your solar/generator/whatever. Never both.

Yes there are many options with as many different functions as you can imagine.

Mine assists solar so on cloudy days and mornings etc it takes what it can from solar and then supplements from the grid if needed.

If I generate more power than I consume it feeds back into the grid and my utility pays me for that power (at a heavily discounted rate).

But mine has to monitor the grid side and open the grid supply breaker if the grid voltage drops below 220 volts for more than 50 milliseconds.

And it won't allow the grid tie breaker to close if there are less than 220 volts on grid side etc.

Since that requires a connection around the tie breaker to monitor grid side it has to be installed by a certified electrician. And the switch has to meet utility requirements for those variables.

The switch you describe would still need to monitor grid voltage and interlock with your solar or generator supply breaker so only one could ever be closed at a time. To meet the code where I live.

There are a couple of physical interlocking designs where one can't close the grid supply breaker if the generator or solar breaker is closed. They even come with a sticker saying it meets code. But when you read the fine print what they meet us that the Interlock doesn't modify your breaker panel in a way that takes it out of code. They specifically do not cover and device or system connected to the panel behind it.

My main point is that you can find some great value when shopping online depending on where the switch sells from. Lots of those switches do not meet requirements. Be very careful as you can hurt someone and or leave yourself open to liabilities if you install some sub standard transfer switch.

I don’t and I don’t have the money to install one. So I’m stuck for now. I need to call the power company and discuss it with them. My info came from Solar salespeople when I was getting quotes and entertaining the idea.
