How to configure a backup CCA and TAP for instant replacement?
We just installed a 20 panel installation with CCA, TAP and TS4-A-O's on all panels.
The inverter I use is a Growatt MIN 6000TL-XH, which is coupled to a 10 KWh battery, also from Growatt. I plan to expand this system with a backup box to make it a full hybrid inverter capable of running off-grid.
As far as I understand, if I power the CCA from the emergency power supply of the hybrid inverter, the system should fully function in case of a grid failure.
But what if the CCA or TAP gets broken? As far as I understand, in that case all my panels will shutdown. So, it seems a good idea to keep a spare CCA and TAP at hand, just in case.
However, what if the CCA or TAP breaks down during some kind of emergency period where there is no grid nor internet connection? How do I replace a broken CCA or TAP with a spare one(s) in that situation?
So, the question is:
How do I configure a spare CCA and TAP, such that I can instantly replace either a broken CCA or TAP in a situation when there is no grid nor internet?

Hello Arend Lammertink,
In a good system build, there should be no reason to keep an extra CCA or TAP on hand, but I understand your concern.
If the CCA is installed somewhere safe (out of the elements), it should last for a very long time. Most of the early Tigo systems are nearing 20 years in activity and still functioning. The TAPs undergo rigorous thermal testing and can withstand great differences in temperature, moisture and pressure (if installed correctly).
With that being said, you may always purchase an extra if you think there will be known complications on site that could damage either product. There is no way to pre-determine the setup on a shelved CCA or TAP, as the process of changing them out is when the serial numbers are entered.
For this reason, The Tigo Support Team is directly available to assist with any administrative steps in the change-out process.0
