Some [[electrical:solar:charge_controller_setpoints|voltage setpoints]] are constrained in relationship to each other. Because of this it may be easiest to configure them in a particular order.((http://techluck.com/cgi-bin/YaBB.pl?num=1486955008)) This order places the configurations in increasing (or equal) voltages the way the controller wants it. | |

| 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]]. |

| 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 down in this order((http://techluck.com/cgi-bin/YaBB.pl?num=1486955008)) (lowest to highest voltage) to make sure the logic below is followed. Then program them into the controller. |

- "Low Voltage Reconnect Voltage" (load)((reconnect loads after regaining this voltage)) | - "Low Voltage Reconnect Voltage" (load)((reconnect loads after regaining this voltage)) |

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]]. |
