346-00000-00 CCA Cloud Connect Advanced Outdoor Data Logger and Rapid Shutdown Controller

Great product but setup is a hassle.

IMPORTANT TIP: If you use that with a system like Ecoflow where you have some batteries, are connected to the grid too, but you do not generate to the grid. (basically you run a subpanel from solar + batteries and only switch to grid if you didn't generate enough power), you need to plan to power the CCA during a true power outage. Otherwise when you really need if, you won't have any solar generation. So ideally have this on a small UPS if your system will take too long to switch to solar and if it will not enjoy solar going off then on again within a few seconds. I dropped one star for the price and difficulty to find some places to buy the device. Overall if you use Tigo, this works very well. I have 12 panels with Tigo optimizers (+ rapid shutdown). The optimizers work for me, I can see per panel how they are producing, I can see how much more power I get daily from them (answer is it depends, but up to 20%). I love the rapid shutdown. I tried it with both a big red switch on 2 pins and also just turning off the power to the CCA. Less than 3 seconds later, less than 1V on the wires at the inverter. Both strings were off very safely.

Allows me to observe the functions of my panels from anyplace in the world. Be sure to play attention to how you wire it. The documentation for the device is good and there are lots of good YouTube videos as well, but if you get distracted it is possible to cross your wires.

Could not find the reason why this unit isn't putting out any output power to the TAP unit. Customer services wasn't able to explain why. Customer services keep insisted to check the wires from the CCA unit to the TAP unit. Nothing wrong with the wires.
