OK, so I have a 36v system, that is constant correct? However, as Watts rise, amps will rise too correct? Or are Amps a constant too??
Amps/Watts quesiton.

The battery voltage should be used to describe the system voltage. The voltage and current delivered by the PV array into the charge controller will be determined by how it is wired and the environmental conditions.Last edited by sensij; 09-18-2017, 11:29 AM.CS6P-260P/SE3000 - http://tiny.cc/ed5ozx -

What is your battery voltage? What kind of charge controller? 36 V is not a common system voltage. You might be right, but haven't shared enough information to be sure.CS6P-260P/SE3000 - http://tiny.cc/ed5ozxComment

Do you have a battery system? A 36V battery bank is rare and odd. much more common would be 12V, 24V, or 48V
if you are talking about the PV modules then they have a VOC voltage that could be 36V but what it puts out at any time could be very different from that.
basically Watts = Amps X VoltsOutBack FP1 w/ CS6P-250P http://bit.ly/1Sg5VNHComment

If it is the PV voltage that you are talking about then the voltage would not be constant.
you're statement of " are Amps a constant too?" implies that you suspect that something other than Amps is constant in solar. Such are Watts or Volts. Neither is constant.
The Watts, Volts, and Amps will vary from moment to moment based on the MPPT formula, PV modules specs, available light, and temperature of the PV modules.OutBack FP1 w/ CS6P-250P http://bit.ly/1Sg5VNHComment

But as others have stated when it comes to solar panels the Vmp or Voltage at max power usually stays the same when the panel is producing. The Amps will change based on the amount of sun hitting the panel which in turn changes the Watt output in linear relation to the Amps output.Comment

If you look at the formula, you could get 200 watts at ~2.7 amps by doubling the volts - hence why BD is qualifying the response.Comment

my array runs ~110V but I have a 48V batter bank.
you would have a hard time charging a 36v batter with a 36v array. To charge batteries you need a higher voltage...OutBack FP1 w/ CS6P-250P http://bit.ly/1Sg5VNHComment
