Step 1: Choose mounting location Locate the MPPT40CC on a vertical surface protected from direct sunlight, high temperature, and water. Step 2: Check for Clearance Place the MPPT40CC 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 airflow. - Page 9 Step 1: Battery Wiring WARNING: Risk of explosion or fire! Never short circuit battery positive (+) and negative (-) or cables Figure 3-1 Battery wiring Before connecting the battery, measure the battery voltage. It must be over 9V to power the controller. For 24V, the voltage must be greater than 18V to properly detect a 24V battery.
- Page 10 shown. Do not insert a fuse at this time. Confirm the connection is correct and then turn on the power. If wiring the load connection to a load distribution panel, each load circuit should be fused separately. The total load draw should not exceed the 20A load rating. Step 3: Solar Module Wiring WARNING: Risk of electric shock! Exercise caution when handling solar wiring.

4. Operation 4.1 MPPT Technology The MPPT40CC utilizes Maximum Power Point Tracking technology to extract maximum power from the solar module(s). The tracking algorithm is fully automatic and does not require user adjustment. MPPT technology will track the array’s maximum power point voltage (Vmp) as it varies with weather conditions, ensuring that the maximum power is harvested from the array throughout the course of the day. - Page 12 Output Power (12V System) Current vs. Voltage (12V System) Typical Battery Maximum Maximum Voltage Range Power Point Power Point Traditional Controller Operating Range Figure 4-1 Nominal 12V Solar Module I-V curve and output power graph The array Vmp is the voltage where the product of current and voltage (Amps × Volts) is greatest, which falls on the knee of the solar module I-V curve as shown in Figure 4-1.

Equalize WARNING: Risk of explosion! Equalizing flooded batteries can produce explosive gases, so a well-ventilated battery box is necessary. NOTE: Equipment damage! Equalization may increase battery voltage to a level damaging to sensitive DC loads. Ensure that all load allowable input voltages are greater than the equalizing charging set point voltage. - Page 15 Charging Indicator The green LED indicator will turn on whenever sunlight is available for battery charging. Under normal charging conditions, the green charging LED will stay on at all times. The charging LED indicator flashes when the battery reaches over- voltage.
