Charge controller done

The MN KID 30A might be another option ...

Estragon, what version of windoze are you using?

I did a recent W7 update and once the laptop has been used for an update, it is almost a one-step operation... once the laptop is used for a FW update, the Port is remembered and the new GUI is much simpler, select the unit model and off it goes. 
Classic was faster  but the MNGP was a lot slower..... The 'give it time' adage still applies!...  don't be in a hurry to close the GUI!!

I've been reading thru the manual for the TS-MPPT 60 and I see what looks like (to me at least) a big difference in charging method from my Rogue MPT-3048. The Rogue, when it went into absorption, operated on end amps (1st) and time (2nd) to determine when to go to float, end amps setting was I think recommended 1% of amp/hr of bank (approx 2.3 amps in my case). If loads kept charge amps from going down to that level, then the time setting would end absorption. As I see it, absorption in the TS-MPPT 60 is only based on time? I've watched videos on doing the custom settings on it too, and see no mention of "end amps" in regards to ending absorption, this will result in my batteries spending much more time in absorption then they did previously I think. 

The TS60  MPPT is different, not better or worse, the end amps associated with some other CC is not part of the algorithm, it works on a percentage of duty cycle, associated with time, when the duty cycle falls below 30% for a cumulative time of one hour, float is initiated, depending on loads present, this may not be achieved as the percentage may be held above 30%. Description from Morningstar below.
 
The duty cycle is used to determine when to transition into float.  The duty cycle is derived from a square waveform and the percentage of time - out of each complete cycle - when current is allowed to flow. Current is regulated by opening and closing the PV-battery circuit -- the essence of a series charge controller. A 50% duty cycle means that current is flowing, and interrupted for, half of the cycle. Our controllers pulse with a frequency of 300 Hz, so each cycle lasts 1/300th of a second. By varying the duty cycle, we can control the average current going into the battery so that the regulation voltage is maintained but not exceeded. As the battery reaches full charge at a particular voltage, it will require less and less current to maintain that voltage and the duty cycle will decrease. The duty cycle will approach zero %, but will never actually get there because losses and battery self-discharge require at least some current to maintain regulation voltage. A Morningstar controller's float transition algorithm waits for the duty cycle to reach 30% or less before starting a one hour timer. When the timer expires, the controller moves from absorption to float voltage. A 30% duty cycle simply means that 30% of AVAILABLE charging current is allowed to pass. Duty cycle is the best measure we have to determine how deep a battery may be in regulation. Factors affecting the accuracy of this method include: 1. Reduced radiation and current. With less available charge current, the duty cycle will inevitably be higher making the transition to float more difficult; 2. Load on the battery. Loads on the battery drain current from the battery which causes a higher duty cycle. If the load is large enough (greater than the amount of solar current ) it can pull the controller into 100% duty cycle and out of absorption - into bulk charging; 3. Aging batteries. Old batteries tend to absorb more current at regulation, keeping duty cycle high. Sulfation leads to higher internal resistance, and more energy loss in the form of heat, which leads to excessive water loss.

Without something like a Midnite WBjr, or a system with no loads while charging, end amps will just be an approximation anyway. Loads can stop the CC from seeing end amps so absorb times out.

You might want to set it for 3-4 hours, and on a good solar day check charging (no load) current at 1/2hr intervals after 1.5hrs to see when it gets to 1%C with your Vabs and batteries. It's around 2hrs on my system.

There is one thing more that will accurately measure end amps. You probably do not see it but if you had a complete Outback or Schneider system, the Inverter talks with the chargers thru the interface bus and accurately measures end amps along with the  AC load doing the math internally. It is the reason I insist on this for my systems. I really have not had a chance to try a Magnum system but it would be pretty bad if they did not do this also now that they make a CC.
