I have 4 265 watt panels that I want to use to charge 8 T-105's

I was thinking two Kid units, but wanted to get your opinions

    Hi, this is a 12 V batt bank, I'll travel mostly based in central FL then hard to say for a total of 3-4 months for weeks at a time May-Oct.
    the panels are Hyundai, voc, 37, isc,8.6, vmp 31.
    I planed on wiring them in parallel due to possible shading issues when parked.
    4 panels are max no expanion planned, my last setup was with 600 watts and it was almost enough

    You are going to need a MPPT  CC with those panels, 4×265W too high for 2 MS Kid CC at 12V, to the best of my knowledge. Cant go 24V? Would make things somewhat easier.
    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.

    the Kids can handle them, talk to support, can't do 24v
    looking for alternative to two kids at about $600

    looking at OUTBACK, FM80-150VDC, MPPT CONTROL, FLEXMAX 80 CHARGE CONTROL 80A 12-24-48V

    thanks

    Midnite Solar Classic 150 SL, solar only. Street price in the $500.00 range. I see one for $491.00 W/free shipping.

    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.

    My error, good to see you have researched your opinions, was thinking along the lines that the Kid was 30A maximum, alway easier with one controller and often cheaper.

    For a camper, I might suggest a fanless design, such as the Morningstar TriStar MPPT 60. While it says It handles up to an input of 800 watts for 12 volt conversion, Normally that is all you will have with 4 - 265 watt panels, more won't hurt the charge controller. This si the same reasoning that allows the kid to handle more.

    Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites,  Midnite E-panel, Magnum MS4024, Prosine 1800(now backup) and Exeltech 1100(former backup...lol), 660 ah 24v Forklift battery(now 10 years old). Off grid for 20 years (if I include 8 months on a bicycle).
    - Assorted other systems, pieces and to many panels in the closet to not do more projects.
