6. Ntọala na nwụnye

Follow these steps for proper installation of your MPPT solar charge controller. Ensure all power sources are disconnected before making any connections.

1. Jikọọ batrị: Connect the battery to the charge controller's battery terminals. Ensure correct polarity (+ to + and - to -). The controller will automatically detect the system voltage (12V ma ọ bụ 24V).
2. Jikọọ ogwe anyanwụ: Connect the solar panel to the charge controller's solar panel terminals. Ensure correct polarity.
3. Connect the Load: Connect the DC load to the charge controller's load terminals. Ensure correct polarity.

Ihe dị mkpa: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load, then solar panel, then battery.
