Fuses

Fuses must be installed on any wires connected to a battery's positive terminal and
located as close to the battery as practical. Refer to Figure 2.4.2 for recommended
fuse locations. All fuses used must be UL listed
. REDARC recommend the use of MIDI

MPPT Solar Regulator

The Manager30 is designed for use with 12V solar panels. Any solar panel
connected to the system must be UL listed
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 Manager30 features 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 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 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
Manager30 will not draw more than 520W 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.
