2.6 MPPT Solar Regulator
The Manager30 is designed for use with 12 V solar panels. A minimum input voltage of 9.5 V 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 9 V and as high as 32 V; 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 Manager30 utilizes 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 Manager30 solar input, on the condition that the open
circuit output voltage of the array is at least 9.5 V and does not exceed 32 V. For this reason, 12 V 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 Manager30 will
not draw more than 520 W from the solar input.
For installations with a single 12 V 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.
