Solar-Panel to Controller Loss
Much has been made of the lower losses on the panel to controller path with MPPT because the amps are less. So once you have your loss measured, how valuable is it to improve on that if you don't lik...

It appears the mppt controller is not functioning correctly. Are you reading a panel voltage of 25.6V? What's the Vmp spec?pnichols wrote:BFL13 wrote:
24v MPPT- 25.6v/7.95a (203w)
24v PWM-- 25.5v 7.99a (204w)
For lack of a better phrase ... you're results above are "impossible", aren't they ... in that they appear to show no advantage to use of an MPPT controller? :h :B
Salvo, I posted those details not long ago and you said it was all "trash" If you are now actually interested, please re-read the earlier thread (230w panel)
http://www.rv.net/forum/index.cfm/fuseaction/thread/tid/28346912.cfm
and the similar info in this thread for the 255w panel
255W panel is Canadian Solar CS6P-255P
Vmp-30.2
Imp-8.43
Voc-37.4
Isc-9.0
My Eco-Worthy is working the same as JiminDenver's and his gets the same amps out as his fancy Morningstar. There is nothing "wrong" with my MPPT controller.
JiminDenver's 250w panel (another case of higher Voc and lower Isc)
