    Four panels in series will be problematic. Is the voltage shown the Voc. or Vmp.? What are the other stats of your panels? Watt rating? Another consideration is what is your system voltage? You may, or may not have too much panel for a 60 amp controller, depending on system voltage.

    2.1 Kw Suntech 175 mono, Classic 200, Trace SW 4024 ( 15 years old  but brand new out of sealed factory box Jan. 2015), Bogart Tri-metric,  460 Ah. 24 volt LiFePo4 battery bank. Plenty of Baja Sea of Cortez sunshine.

    This link will assist in designing the optimal arrangement with your particular panels, assuming you are referring to the Morningstar T 60 MPPT  http://string-calculator.morningstarcorp.com
    1500W, 6× Schutten 250W Poly panels , Schneider MPPT 60 150 CC, Schneider SW 2524 inverter, 400Ah LFP 24V nominal battery with Battery Bodyguard BMS 
    Second system 1890W  3 × 300W No name brand poly, 3×330 Sunsolar Poly panels, Morningstar TS 60 PWM controller, no name 2000W inverter 400Ah LFP 24V nominal battery with Daly BMS, used for water pumping and day time air conditioning.  
    5Kw Yanmar clone single cylinder air cooled diesel generator for rare emergency charging and welding.

    From the description given it sounds like a Schneider Conext 60-150 charge controller . If they have a string sizing tool I couldn't find it. Their site is not easy to navigate.

    Don't believe Schneider has one anymore, the t60-150 made me think TriStar, either way both have identical voltage specs, I actually refered to Morningstar string calculator for my Schneider 60-150.
