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 if any contact with battery acid
• Keep the battery away from any metal objects, which may cause short circuit of the battery.
• Explosive acid 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 only recommended, other kinds please refer to the battery manufacturer.
• Loose 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
motion.
• 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/mm2 or less current density in accordance with Article 690 of the National
Electrical Code, NFPA 70.
• For outdoor installation, keep out of the direct sunshine and rain infiltration.
• High voltage still exists inside the inverter/charger after switching o 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 connetion.

• Check all the naked wires to make sure insulation is not damaged for serious solarization, frictional wear, dryness,
insects or rats etc. Repair or replace some wires if necessary.
• Tighten all the terminals. Inspect for loose, broken, or burnt wire connections.
• Check and confirm that LED is consistent with required. Pay attention to any troubleshooting or error indication.
Take corrective action if necessary.
• Confirm that all the system components are ground connected tightly and correctly.
• Confirm that all the terminals have no corrosion, insulation damaged, high temperature or burnt/discolored sign, tighten
terminal screws to the suggested torque.
• Check for dirt, nesting insects and corrosion. If so, clear up in time.
• Check and confirm that lighting arrester is in good condition. Replace a new one in time to avoid damaging of the
inverter/charger and even other equipments.
