Yes, TS4 is compatible with any inverter or charge controller that has its own MPPT functionality. The list of inverters/charge controllers that Tigo is currently compliance tested with is available here.
Rapid Shutdown Notes: For an off-grid installation to support rapid shutdown, power your CCA/CC (Cloud Connect Advanced/Cloud Connect) via its own power supply with a switch. Then to shutdown the system's modules:
- Switch off/disconnect the CCA from its power supply
- Turn off the charge controller.
The above two steps will send the system into shutdown mode.
Note: if you require Rapid Shutdown in an off-grid system, you should have Tigo's Mesh software on your system. You can verify this by sending a request to "firstname.lastname@example.org" with your system ID.
To reactivate the system after rapid shutdown:
- Switch on/reconnect the CCA to its power supply
- Turn on the charge controller
The above two steps will bring the system's modules back online.
