2 Installation

2.1 General Installation Notes

 Before installation, please read through the entire installation instructions to
get familiar with the installation steps.
 Be very careful when installing the batteries, especially flooded lead-acid
battery. Please wear eye protection, and have fresh water available to wash
and clean any contact with battery acid.
 Keep the battery away from any metal objects, which may cause short circuit
of the battery.
 Explosive battery gases may come out from the battery during charging, so
make sure ventilation condition is good.
 Gel, Sealed or Flooded batteries are recommended, other kinds please refer
to the battery manufacturer.
 Ventilation is highly recommended if mounted in an enclosure. Never install
the controller in a sealed enclosure with flooded batteries! Battery fumes
from vented batteries will corrode and destroy the controller circuits.
 Loose power connections and corroded wires may result in high heat that
can melt wire insulation, burn surrounding materials, or even cause fire.
Ensure tight connections and use cable clamps to secure cables and prevent
them from swaying in mobile applications.
 Battery connection may be wired to one battery or a bank of batteries. The
following instructions refer to a singular battery, but it is implied that the
battery connection can be made to either one battery or a group of batteries
in a battery bank.
 Multiple same models of controllers can be installed in parallel on the same
battery bank to achieve higher charging current. Each controller must have
its own solar module(s).
 Select the system cables according to 5A/mm
accordance with Article 690 of the National Electrical Code, NFPA 70.
