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.
Hybrid and Off-Grid Rapid Shutdown Systems with Tigo’s Fire Safety (TS4-F)
Below is an example of a Schneider Electric system with integrated RSS Transmitter.
In the system shown, Schneider's MPPT Disconnect RS has the Tigo RSS transmitter built-in. Turning its switch to the "OFF" position causes rapid shutdown to happen. Schneider's MPPT 80 600 is an RSS compatible charge controller.
For more information on Tigo's TS4-F and the associated RSS (Rapid Shutdown System) products, see our article, "Design Essentials for TS4-F/-A-F".
Tigo’s Fire Safety solution – including the integrated TS4-F, add-on TS4-A-F, and add-on for 2 modules TS4-A-2F - can be used for PV rapid shutdown with charge controllers that are tested and validated with a compatible rapid shutdown transmitter. Charge controllers that are compatible with Tigo’s Fire Safety solution include:
- Schneider Electric MPPT 60 150 charge controller with the MPPT Disconnect RS
- Schneider Electric MPPT 80 600 charge controller with MPPT Disconnect RS
- Delta E8-TL-US with a built-in RSS Transmitter
- Delta E6-TL-US with a built-in RSS Transmitter
- Solax A1-Hybrid-6.0 with a built-in RSS Transmitter
- Solax A1-Hybrid-7.0 with a built-in RSS Transmitter
- Solax A1-Hybrid-7.6 with a built-in RSS Transmitter
- Solax A1-Hybrid-8.6 with a built-in RSS Transmitter
Hybrid and Off-Grid Rapid Shutdown Systems with TS4-S (Safety), TS4-O (Optimization)
Tigo’s Safety and Optimization solutions – including the integrated TS4-S & TS4-O, add-on TS4-A-S & TS4-A-O, and add-on for 2 modules TS4-A-S-Duo & TS4-A-O-Duo - can be used for PV rapid shutdown with charge controllers that are tested and validated with a compatible rapid shutdown system (RSS). These TS4 products need to be installed with Tigo communication accessories (TAP, CCA). Charge controllers that are compatible with Tigo include:
TS4-O (Optimization)
- Delta E8-TL-US
- Delta E6-TL-US
- Solax A1-Hybrid-6.0
- Solax A1-Hybrid-7.0
- Solax A1-Hybrid-7.6
- Solax A1-Hybrid-8.6
- Pika X11400 + PV Link
- Pika X7600 + PV Link
- Midnight Solar Classic Legacy P&O
- Midnight Solar Classic Regular (Solar)
TS4- S (Safety)
- Pika X11400 + PV Link
- Pika X7600 + PV Link4
- Midnight Solar Classic Legacy P&O
- Midnight Solar Classic Regular (Solar)
For a complete list of inverters and charge controllers that have been tested and certified by Underwriter's Laboratories (UL) for rapid shutdown, see this UL Product Spec. The TS4-F section is at the bottom.
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 "support@tigoenergy.com" 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.
For more about rapid shutdown, see this article.

What size battery would you suggest we use as a back up to the CCA. Imagine if it was 12 volt and your Off Grid house system was running a 48 volt system. Therefore, if during winter conditions and a 'low voltage disconnect (cut out) happened, the battery would take over for a period of time. It might be a day or two until it was powered back up. The 12v battery would be charged by a trickle charger plugged into the 'home grid'. Transmitter at 1 amp x 24 hours is 24 Ah bat for one day... so perhaps a 50 - 100 Ah battery..? In case there was a delay in getting the 48 volt system back up on to trickle charge the 12v back up battery... otherwise, with out the RS receivers closed and pv power flowing, the 48v system can't charge without a generator input.. (or a jump start!).
Any thoughts would be helpful.
