Precautions
Assembling the SRA’s All-Weather PVH Kit requires working around electrical systems and
batteries. Please use caution when working on electrified systems. De-energize the system by
disconnecting PV panels and batteries before servicing the system in any way.
The SRA’s All-Weather PVH Kit, once assembled, is large and heavy. Two people are required
for assembly and mounting to the tower.
During assembly of the SRA’s All-Weather PVH Kit, do not connect PV panels until the system
is ready to be put into service.
Kit #11709 & #11710 contain multiple 12V deep-cycle batteries that must be connected
together into a battery bank. Check the orientation of the batteries and polarity of the
terminal posts before attempting to chain the batteries together! Serious injury could result
from an improper connection.
Notes
-Slide nuts used in this kit have one side with a lip around the threaded hole. When inserting a slide nut
into an extruded aluminum rail, the lip should always face the center of the rail, not outward towards
the bolt. Failure to do so can prevent the nut from sliding easily inside the channels of the rail.
-Do not overtighten bolts. Overtightening bolts may result in damage to hardware.
-Loctite 242 has been provided in all hardware kits. NRG recommends that Loctite be applied to all slide
nut threads to help prevent loosening over time. Pre-assembled components have Loctite applied
already.
SECTION 1: ASSEMBLING THE ALL-WEATHER SYSTEM TOWER
1.1 Construct and Erect the 2.2m Tower
The
SRA’s All-Weather PVH Kit
includes a 2.2m NRG SRA tower assembly (kit #9118). Construction of this
tower is recommended prior to assembling the PV brackets. Choose a suitable location for the tower
that is close enough for sensor wires (5m length) to reach your NRG SRA System and data logger.
Orient the guy ring and wires so that the PV frame will fit in between two guy wires.
Please read the SRA manual for instructions about how to safely erect the tower. To download the
