Yep, I bought one for testing modules and installations. The kit is designed for European installations where the connection to the inverter is via MC4 or Sunlink connectors. You can disconnect the inverter, connect the Seaward, and test the system. Similarly the strings are plugged into the bottom of the combiner, so you can test each of the strings quickly.
The NEC method requires hard wired connections and conduit, so there is nowhere to connect the test set. I have suggested Seaward provide 1000V rated alligators clips so we can test the strings at the fuseholder. I bought some Fluke test leads with the intention of putting MC4 connectors on them as an adapter, have not done that yet as I got to like them on my Fluke! For string testing, we use a long lead and test at each end of the string instead of at the combiner. The set is very useful for testing modules. We have a shipment of used modules and I wanted to test every unit prior to installation. That is very quick to do. The ability measure the irradiance and temperatures and record that with the module performance to a dataset is useful, and one way to stand out from the crowd. It makes commissioning very professional. I wish we could input the bar code at the same time. The Solar Survey 200R irradiance meter is also a very useful temperature logger for testing solar thermal installations and for checking module temperatures. My only gripe, other than the connection issue, is with module performance. I really wanted the system to be able to give me the module rating. I would like to download the data and see the actual module performance, adjusted for irradiance and ambient/module temperature. As it is, I get the Voc and Isc. Nice piece of kit, very useful, great way to test for ground faults, ground resistance, Voc and Isc, very quickly and to record the results to your computer. I think in time we will be required to do this for certification as the British are.
