-Some [[electrical:solar:charge_controller_setpoints|voltage setpoints]] are constrained in relationship to each other.   Because of this it may be easiest to write them out in this order((http://techluck.com/cgi-bin/YaBB.pl?num=1486955008)) to make sure the logic below is followed.  +

 +The algo is slow but performs very well under good solar conditions.  Under poor or rapidly-changing solar conditions [[opinion:frater_secessus:epever|it may underperform]].

 Because of a tweak Renogy made to their version of the controllers, the plain MT-50 will not work and you must pay extra for [[https://amzn.to/2YueTzP|the Renogy MT-50]].   Because of a tweak Renogy made to their version of the controllers, the plain MT-50 will not work and you must pay extra for [[https://amzn.to/2YueTzP|the Renogy MT-50]].
