I have bought epever tracer 4210A charge controller http://www.epsolarpv.com/en/uploads/news/201512/1449040581526220.pdf

I would like some help in wiring this positive grounded controller.

Here is what i understand, explain where i am wrong;

1. Panels to Controller: positive of panel goes to positive input on controller, negative to negative.

2. Controller to Battery: positive of battery goes to positive battery terminal on controller, negative to negative.

3. Controler to Load: Positive of load to positive of load terminal on controller. Negative to negative.

4. Direct battery to Load: Battery positive connects to Load Negative. Battery Negative to Load Positive?

5. How to physically ground the system? Connect positive of battery to some metal frame?

Will be waiting for your replies

Thank you

    Connect positive battery to ground, unit itself is common positive.

    I would would connect my "direct battery to loads", this way:
    4. Direct battery to Load: Battery positive connects to Load Positive. Battery Negative to Load Negative?

    Page #12 of your Manual has a drawing showing you exactly how to make every connection.
    Including the ground wire, fuses and circuit breakers.

    Your Ground Wire should be connected to a Ground Rod.
     "Metal Frame" is ambiguous.
