General Installation
Cable installation should comply with all local regional and national regulations. In most countries, a
ground fault protection device (GFDI) must be installed between the solar panel and air conditioner.
Select a GFDI in accordance with local regulations. The electrician must identify the positive pole
and negative pole. Reverse connection may cause permanent damage to the system.
Use qualified photovoltaic cables only. The cable can resist UV rays and rapid climate change. The
rated voltage of the cable should be more than 600V. The cross section area of the cable depends on
the maximum short circuit current and the length of wire. Be very careful when installing the cable
at extremely low temperature. It is recommended to use the cable of cross section area of 4mm or
greater, and the wire should be as short as possible to reduce the energy consumption.
Detailed Installation Instructions:
If you ordered your mounting hardware from somewhere other than HotSpot Energy, consult with
your supplier for detailed instructions If HotSpot Energy provided the hardware, it will either be
from Iron Ridge or DPW. Please download and follow the appropriate detailed instructions.

WEEB Washers are designed to bond solar PV panels to
mounting structures. The washers are made of 304
stainless steel and have teeth that embed into the
aluminum mounting structure to form a gas tight
electrical connection.
Used as an alternative to grounding each panel with
grounding lugs and ground wire., WEEBs do not ground
the mounting structure to earth ground, only the panel
to the frame. A ground wire must be run to each row of
rails and grounded with a ground rod or the main
service ground.
