Yes thats right .its no big deal just takes some thought

I thnk you have it right in terms of a non grid tied system and PG&E is out of that loop. I am wonding about the 8 415V panels feeding 30 KW of power . I am feeding 24 400w panesl to a 22.5 Kw battery bank and in winter we need all of them. We are 5 hours north of your location just north of...

I have zero reason now to activate my system thru the CCA. The optimizers are working and thats all I need them to do, I never need rapid shut down. If I have a wildfire I will go to ground mount and to solarc and throw the off switches..We get power outags about avering 7 times a year herd in...

I do not have that part in my tigo system that I'm aware of

I think a call to Tigo is needed to get to the bottom of this. In theory you could supply the CCS with solar power/battery power and never have it shut down.The device is made for firefighters I belive to access the roof after power shuts off and have a dead system. That said if you have grid...

It appears to me that 110v or 24v can power it up. Once poewered up it can never be set back to off and needs power forever.. The tigos optimze without this system turned on ,you just cannot see whats up on the web which is what I have been doing for years now .

This is what mine looks like-I forgot to add this to my post above

Ok so in the photo is my tigo power supply-. You are saying that the small box on the left is a step down transformer that knocks the feed thru the breaker on right to some DC voltage (your link did not work). I can meter this to find out if its 24 or 48 v.. For my application (no inspectors...

I thgink once the tiro system is powered up with 110v and the power goes out it shuts down and thats that. Not sure what is meant by using DC to power it up?Its off and staying off unitl 11110v is restored

Also if you are doing your own buy the hvac torque wrench metric set. Its a must have to get it right for line sets.

One note on mini spits is surge suppression . The best is to have a unit close to your compressor which has delicate curcuit board controls that get fried easy. I learned about these from Hvac friends . Mars makes ones that connect to your power box feeding the unit power .They pug into a knock...

I have 3 mr cools. I'm just finishing the 3rd install. I have a smaller 110 v 12k unit about 6 years old (second or 1st generation)and an 18k unit put in in 2021 3rd Generation 220v . and now another 4th generation 18k 22v unit. I have done custom installs hiding the extra line sets in attic or...
