What's it MPPT?
MPPT (Maximum Power Point Tracking) is a power electronic technology mainly used in photovoltaic power generation systems, wind turbines, and On-Board Battery Charger. Its core function is to adjust the output power of the device according to changes in the external environment, such as temperature and light intensity. By ensuring the equipment is always operating at the maximum power point, it enhances energy conversion efficiency, making it a crucial component in systems where efficient energy utilization is essential.

Procedure
Verify battery type, capacity, and generator compatibility.
Prepare necessary installation accessories, such as ring terminals, fuses (60A recommended), solar adapter cables, and ignition signal cables.
The starting battery is connected to the input terminal for the main power supply while the vehicle is running.
The solar panel is connected to the PV input port via MC4 with a maximum input power of 660W.
The service battery is connected to the output to complete the energy storage and ensure correct polarity.
Depending on the
battery type (such as lithium batteries), select the charging mode via a dip switch or an APP (such as DC Home).
Enable the remote monitoring function using an RS485 communication cable.
Check that all connections are secure and that there is no risk of short circuits.
Turn on the power and observe the LED indicator or monitor the working status of the application.
Notice
Safety: Always use a fuse or circuit breaker to prevent circuit overload.
Temperature management: The installation location should avoid hot areas and optimize charging with the built-in temperature sensor.
Regular maintenance: Check cable connections and device status to ensure long-term stability of the system.
