That is where I bought my SS/raspberry pi package.

In addition, and another poster mentioned that storing energy on the grid is 100% efficient, with grid tie there is another aspect that there alway somewhere for excess solar to be stored. Whereas with off grid when batteries are full and loads are satisfied the charge controller just ramps down...

We don't typically use grounding rods to dump excess power which can be controlled by other means. We use ground for things like lightning and insulation breaks that create unsafe conditions.

My guess is the OP will get an ambiguous answer from the POCO. Get a building permit and verify that your inverter cannot backfeed and move on.

If I were doing that, instead of risking that I would mess up the device that tells the Mobile Connector the kind of plug I was using which might disable the Mobile Connector for that plug, I would make a pigtail to a TT30 receptacle. That does not test the assumption that you can charge at a...

It tyically is one of the Investor Owned Utilities that make that decision. It would be determined by the status of your application with them and whether it was tentatively approved. Perhaps the structural issues resulted in changes in your application which caused the initial date to be reset...

That is the way I look at it except for Non Bypassable Charges which cost me $0.025 per kWh which is still less expensive than a battery. I do use the grid as a seasonal battery because my winter loads are high when my production is low. I also use a traditional battery to do peak shaving...

That is what I started doing before I got sidetracked. Eventually I am going to revive that project because Home Assistant interfaces with some other home automation devices which I have. I can do simple relay logic programming but have no desire to learn Perl at this time in my life.

There are two versions of the mobile connector and if I remember correctly the adapter cable is different for each version. I also remember that the adapters had a resister or other device in them that told the mobile connector what current to set the Tesla at. I don't know if it also tells it...

Do you have a link to that Webinar? I did not find it on the SolArk listing of Webinars. I did hear that it was delayed for a couple of weeks. My PVPro is still working.

What kind of current and voltage are you seeing at the panels? Buying 8 guage is a waste of money if your panels are not putting out more than 30 Amps and your voltage is safely above the minimum for your charge controller.

And if you go to larger micros the number of micros per string will be reduced so that will also mean more work restringing. Have you done a comparision on PV Watts seeing what the increase in annual production would be and quantified that into a payback of the cost in dollars and time on the...

Most efficient inverter driven units run the compressor all the time, but at lower levels of power so the result is the same without the start up surge. I suppose that is one way they achieve the higher efficiecy numbers.

I agree. In the larger scheme of things, my main service panel is 240 volt split phase and my AC coupled micros are actually 240 volt single phase with no neutral so whatever I can do at 240 volts is a lot more efficient. I iactually rarely charge my EV from the hybrid inverter but I do charge...

Because 240 Volts is more efficient and for the typical split phase inverter it is balanced between the legs. Many split phase inverters cannot handle 60 Amps of unbalanced load.
