4. MAXIMUM POWER POINT TECHNOLOGY
Maximum Power Point Tracking (MPPT) is an advanced charging technology that more efficiently harvests power from
solar panels in all conditions. It does this by continuously tracking the I-V curve of the solar array and modifying operating
conditions to maximize output power. The graph below shows the MPPT point compared to a traditional PWM charger,
which always runs the solar array at a voltage close to the battery voltage.
Due to differences in ambient temperature and light conditions, the maximum power point often changes. The MPPT
controller can adjust parameters according to quickly changing conditions to keep the system near to its maximum
working point. The whole process is fully automatic and does not require any adjustments or interference by users.
The graph below shows how the IV curve of a solar panel changes with varying sunlight conditions.
