Using the Sun2000/1000 GTIL2 on split phase power can be tricky. The manufacturer ships a single CT and pretty much requires the phases to be balanced in order for it to work properly, but having balanced loads between the 2 split phases are rarely the case as our electricity demands are unpredictable.  The manual has a silly recommendation of only measuring 240V loads and no 120V loads or for 120 V loads, you should measure the phase with the highest 120 V loads (who can predict which phase that would be and who can keep track of which phase belongs to which 120 V outlet to guarantee the  higher load).  This recommendation is not only impractical, but can significantly under produce as well.  With the Split CT, you not only limit your export but also maximize on the production limit you set to within 50 watts of your actual total usage giving you a good rate of return on your purchase.
 
We have a simple solution with our Split CT kit. No need to ever calibrate, adjust or modify anything. We provide a Y cable adapter so you can just plug in our Split CT (engineered for the GTIL2) along with the original shipped CT to save money.
 
Installation can not be any easier and no need to have balanced phases ever. It will work under all circumstances and will not allow the Sun2000/1000 to export more than 50W to the grid. We guarantee it.
 
Please note that currently the LCD screen can inaccurately display the load values for split phase power especially if you have some 120 loads (as mentioned in their manual) because it assumes the loads are phase balanced or that you are measuring the phase with the higher 120V loads since only 1 CT is used. As a result, when using our solution, the displayed load is always double of what it should be. However, the output display is correct since it is not using the displayed load values, but rather the direct measurements from the 2 CTs.
 
Comes with a 10 ft cable which is the same length as the original one. We offer other lengths but we can also customize the length for an extra cost (please inquire)
Size of CT has a 24 mm hole and rated at 250A.

1 year warranty with money back guarantee if it does not limit export to under 50 W for split phase system
