Step 2. Positioning the BlackMax
The BlackMax is designed to be a freestanding weatherproof system (suitable for outdoor locations).
It is recommended to locate the system in a shaded area to reduce the
chances of overheating. It should also be placed close to the solar panels to
minimise voltage drop and power loss.
The BlackMax can be secured to the ground via the four holes in the feet of the
system. This can be done with the Dynabolts, or screws supplied in the Parts
kit, or other material appropriate fixings.
Clearance:
Allow 600mm spacing on both sides
of the BlackMax.
If positioning the BlackMax against
the wall of a habitable room, then the
clearance requirements are as per
AS5139 and shown at right, must be
observed. In addition, the wall should
be made of non-flammable material,
if it is a habitable room.
Note: If the BlackMax is placed at
least 300mm off the wall of any
building, then these requirements of
AS5139 do not apply.
Ventilation:
Cooling air flow passes up through the vents in the base of the system and then out the fan located on the top left-hand side of
the unit. Do not block the air vents as the system may overheat and shutdown. If the BlackMax does shutdown because of
overheating, it will automatically restart once it cools down again. The fan is controlled by a temperature switch set to 25
C in
the factory, which can be adjusted on site.
Step 3. Solar array sizing and layout
The PV Array should be designed and installed in accordance with AS/NZS 5033 and
the latest CEC Installation guidelines.
Caution should be taken in selecting PV panels and the wiring method to ensure the
rated Open Circuit Voltage (Voc) and Short Circuit Current (Isc) is not exceeded
(factoring in the coldest and hottest expected ambient temperatures).
The maximum Voc for the BlackMax is 500Vdc. This usually means a maximum 9 panels
in series when using typical 400 Watt panels.
The maximum Isc is 19.5 amps. This means a maximum of one string in parallel when
using typical solar panels. (<15.6A per panel taking into consideration the 1.25x derating
factor of Isc, used in Australia)
