5. Setup uye Kuiswa

Follow these steps for proper installation of your charge controller:

1. Kukwidza: Choose a dry, well-ventilated location for mounting the controller. Ensure there is sufficient clearance around the unit for heat dissipation. Mount vertically on a non-flammable surface.
2. Wiring Sequence:
   • Connect the battery cables to the battery terminals on the charge controller. Ensure correct polarity (+ to + and - to -).
   • Connect the solar panel cables to the PV terminals on the charge controller. Ensure correct polarity.
   • Connect the load cables to the load terminals on the charge controller (optional). Ensure correct polarity.
3. Tembiricha Sensor: Connect the included temperature sensor cable to the designated port on the controller. Place the sensor near the battery to enable accurate temperature compensation for charging.
4. Kutanga Simba-Up: Once all connections are secure, the controller will power on and display system information on the LCD.

Important: Always connect the battery first and disconnect the battery last to prevent damage to the controller.

6. Operating Instructions

The LCD display and buttons allow you to monitor and configure the charge controller.
