What is the maximum solar panel size that can be connected to a PS100?

Although the SP20 delivers approximately 1.17 A in full sun, the limit of the PS100 is approximately 1.2 A. Therefore, Campbell Scientific does not recommend connecting a PS100 to a solar panel larger than 20 W. In comparison, the PS200 and CH200 can be connected to solar panels as large as 70 to 90 W.
