Manual Renogy 40 Amp Commander MPPT Solar Charge Controller Feb 7, 2019 3:34:23 GMT

hello again~!

The manual for the 40 isn't clear is some areas.

Pg 11 "the Commander will be damaged if the PV array is 3X greater than the actual operating power of the controller. "

I conclude that to mean AMPS

Pg 12 "Max PV Array Power 1560W @ 12V" 130AMPS

Watts that's clear.

Now, Pg 22.

Max. Solar Input Power 12V @ 520W

I see a that page 12 and 22 don't state the same; so what is the MAX input power?

520W or 1560W?

Thank you for clarifying.

The controllers OUTPUT is limited to 40A

apparently you can overpower the controller to 120A input (520w/13v X 3) but the controller will clip the excess to 40A output.

The reason to 'overpower' a controller is that 520w will rarely make 40A. Bad angle, time of year, low light, eff, etc.
