MPPT Solar Regulator

The Manager15 is designed for use with 12V solar panels. A minimum input
voltage of 17.5V is required to start charging from a solar source. Once charging
has started, the operating voltage range of the solar input can go as low as 9V
and as high as 32V; outside of this range, charging will stop.
The power output from solar panels varies depending on the amount of sunlight
and the electrical load on the solar panel output. The Manager15 utilises a
Maximum Power Point Tracking (MPPT) algorithm on the solar input, to ensure
that the greatest charge possible is transferred from the solar panels to the battery
under charge. As conditions change, the MPPT algorithm adjusts its parameters
accordingly, in order to maintain the optimum point at which the solar panels can
deliver the most power.
An array of solar panels can be connected to The Manager15 solar input, on the
condition that the open circuit output voltage of the array is at least 17.5V and
does not exceed 32V. For this reason, 12V panels must be connected in parallel
(Refer to Figure 2.6.1). So long as the voltage requirements are met, there is no
limit to the number of panels that can be connected in a solar array; however The
Manager15 will not draw more than 260W from the solar input.
For installations with a single 12V solar panel, a blocking diode is not necessary.
For installations with an array of solar panels, please refer to the panel
manufacturer's instructions for requirement and/or fitment of diodes.
