This is the SA-CT-LG current transformer for use with your Sol-Ark. 100A CTs were included with your Sol-Ark, but for Net Metering applications, if you have a 200A or greater service, you will need to buy a 200A Current Transformer pair. Sol-Ark inverters come with 100A CTs that are appropriate for 2/0 wire. The 200A CTs support 4/0 wire.
