PV Array voltage and temperature have a direct influence on the voltage boost performance.
A PV module at constant solar intensity will vary the power output depending on temperature
changes. Therefore, it is important to note that a cooler PV array can produce a higher voltage,
and therefore more power, than a hot PV array. When the PV voltage is enough for the MPPT
operating range then a constant power output is delivered to the battery.
Therefore, assuming 100% efficiency:
Power In = Power Out
Volts In * Amps In = Volts out * Amps out
The MPPT Charge Controller 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.
The Rover Boost will “boost” up the voltage in the solar system. The power generated in the
solar panels is the same power that is transmitted into the battery bank. Power is the product
of Voltage (V) x Amperage (A).
