Maximum-Power Voltage (V
mp
)
Maximum-power voltage (V
mp
) is the operating voltage for the PV array at which the array
generates the most wattage. When designing the PV array, it is recommended for the V
mp
to be
approximately 12 to 24 volts higher than the nominal battery voltage for optimum performance.
This will ensure that the V
mp
is always above the battery voltage, which is required for charging.
Higher voltages are not recommended, as they may reduce the FLEXmax conversion efficiency.
IMPORTANT:
Check the PV array voltage before connecting it to the FLEXmax.
Standard vs. Australian Default Settings
Several version settings are available for the FLEXmax upon initial setup. These can be
selected upon initial power-up. (See page 17.) The English and Spanish versions have the
same standard default settings; however, the Australian version has certain default settings that
are different. However, there are no differences in performance and efficiency between the two
versions. The standard and Australian version can be identified as follows:
