20A12/24V Auto work MPPT solar charge controller with dual timer

Tracer series solar controller is an advanced Maximum Power Point Tracking (MPPT) controller for off-grid photovoltaic (PV) systems. The MPPT controller features a smart tracking algorithm that maximizes the energy harvest from the PV by rapidly finding the solar array peak power point based on varied temperature. The MPPT controller provides higher efficiency up to 97% with lower power loss.

Tracer is specially designed to work with all established PV modules and is optimized for thin film and grid –tied modules.

1 General Installation Notes
1)Read through the entire installation section first before beginning installation.

2)Be very careful when working with batteries. Wear eye protection. Have fresh water available to wash and clean any contact with battery acid.

3)Uses insulated tools and avoid placing metal objects near the batteries.

4)Explosive battery gasses may be present during charging. Be certain there is sufficient ventilation to release the gasses. 5)Avoid direct sunlight and do not install in locations where water can enter the controller.

6)Loose power connections and/or corroded wires may result in resistive connections that melt wire insulation, burn surrounding materials, or even cause fire. Ensure tight connections and use cable clamps to secure cables and prevent them from swaying in mobile applications.

7)Use with Gel, Sealed or Flooded batteries only.

8)Battery connection may be wired to one battery or a bank of batteries. The following instructions refer to a singular battery, but it is implied that the battery connection can be made to either one battery or a group of batteries in a battery bank.

9) Select the system cables according to 3A/mm2 current density.

2.Mounting

Step 1: Choose Mounting Location Locate the Tracer on a vertical surface protected from direct sun, high temperature, and water.

Step 2: Check for Clearance.Place the Tracer in the location where it will be mounted. Verify that there is sufficient room to run wires and that there is sufficient room above and below the controller for air flow.

Step 3: Mark Holes Use a pencil or pen to mark the four (4) mounting hole locations on the mounting surface.

Step 4: Drill Holes Remove the controller and drill four sizeable holes in the marked locations.

Step 5: Secure Controller Place the controller on the surface and align the mounting holes with the drilled holes in step 4. Secure the controller in place using the mounting screws.

The Tracer series controller is for off-grid solar system and control the charging and discharging of the battery, especially suitable for the street light system. The controller features a smart tracking algorithm inside that maximizes the energy from the solar PV module(s) and charge the battery. At the same time, the low voltage disconnect function (LVD) will prevent the battery from over discharging.
