[RE-wrenches] C-40 question

[Larry Crutcher, Starlight Solar Power Systems]

Well Steve, 
Let me wipe the egg off my face....It is right there on page 59 of Xantrex manual, version 975-0004-01-02 Rev D. "If the current exceeds 85 amps, the transistor switches are opened..." Upon further reading, it appears that all three controllers can handle 85 amps intermittently. I'm not surprised at that since I can't remember seeing a C-Series controller burned up like so many others I have encountered.

Thanks Steve for my continuing education. Are there ANY other non-MPPT controllers out there with a over-current protection?

The C-40 does (or at least did) have Electronic Overcurrent Protection. According to the C-40 manual if the current exceeds 63 amps  the overcurrent protection is activated.  The C-40 automatically resets the OCP every 10 minutes until the problem is corrected or stops. The OCP can also be reset manually by holding the reset switch down for 5 seconds.
