Controller with 2 source renewable energy

Hi ,

I appreciate that your guys can share the control circuit that can charge the battery from 2 source of the renewable energy.

    We would need more information about your '2 sources'. MPPT type controllers would not work, or at least not well if the voltages varied between the 2 sources. PWM charge controllers would work, if the voltages of the sources were within their range, and power (wattage), above the batteries needs would be lost.
    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, 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.

    You can usually use two charge controllers feeding one set of batteries.
