Apollo T80 & Accessories

Item Description Number

Apollo T80

Apollo Solar can out with the first controller to exceed the MX60 in specifications by a great degree. It 80 Amp @ 40C spec beat the MX60's 60A @ 25C by about 50%. Learn More from http://www.apollosolar.com/

As of 2008, the shunt is no longer included...



The T80 has one of the largest wiring compartment of any controller (even the new XW from Xantrex is not quite as large.

In comparison to the MX60, the T80 is larger, but not by much. The super large heat sink, means the large industrial fan will not likely have to come on often, even at 80Amps output...
