2. Installation Instructions

2.1 General Installation Notes

 Please read the entire installation instructions to get familiar with the installation steps before
installation.
 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.
 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.
 Lead-acid battery is recommended, other kinds please refer to the battery manufacturer.
 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.
 Select the system cables according to 5A/mm
Article 690 of the National Electrical Code, NFPA 70.
 For outdoor installation, keep out of the direct sunshine and rainwater infiltration.
 High voltage still exists inside the inverter/charger after switching off the power switch, do
not turn on or touch the internal units, conduct the associated operation only after
discharging the electric capacity.
 Do not place the inverter/charger in a damp, oily, inflammable and explosive or a severe
environment with a large amount of dust accumulation.
 Prohibit reverse connection at DC input end otherwise it may damage the equipment or
unpredictable danger will occur.
 The utility input and AC output are of high voltage, do not touch the wire connecting
locations.
