All Gen 2 devices are the same model (regardless of system type) - so the main consideration when determining what kind of Gen 2 kit to pickup is how many sensors would be needed for the installation.

200A CT's:

If on three-phase electrical, you'll need to pickup a Gen 2 kit with 3x included 200A CT's since you'll want one on each phase of power for your main lines (no sensors on the neutral line).

If on single or single-split (two) phase electrical - then any of the Gen 2 kits will work since all Gen 2's include at least 2x of the 200A CT's in each package. For single phase installations, you'll only need one 200A CT on the live main, no sensors on neutral.

50A CT's:
For the number of 50A CT's required - very much depends on the number of circuits you'd like to capture details for. If looking to conserve sensor count - then prioritizing your higher loads/consumption is usually a good place to start. Can always expand and add more sensors/devices at a later time if wanting more details.

Multiple Devices?

If needing to monitor multiple panels, or more than 16x branch circuits (port/sensor limitation on the Gen 2 for 50A CT's) - then you can certainly use more than one Gen 2 together to capture more details. Information about how to setup multiple devices in these situations can be found here.

Other:

Outside of the Gen 2 hardware, here are some other local requirements for the device to work:

Each Gen 2 kit will include all of the hardware needed to get the device up and running, so the WiFi antenna, Wire Harness and everything to get it working will be included in each Gen 2 package.
