Installation

Warning

• Please read the manual carefully to get familiar with the installation steps before installation.
• Be very careful when installing the batteries, especially flooded lead-acid batteries. Please wear eye protection, and have fresh water available to rinse if any contact with battery acid.
• Keep the battery away from any metal objects, which may cause a short circuit of the battery.
• Loose connections and corroded wires may result in high heat that can melt wire insulation, burn surrounding materials, or even cause a fire. Ensure tight connections and use cable clamps to secure cables and prevent them from swaying in motion.
• Select the system connection cables according to the current density no higher than 5A/mm2. (Following the National Electrical Code Article 690, NFPA70).
• For outdoor installation, keep out of the direct sunshine and rain infiltration.
• High voltage exists inside the inverter after turning off the switch. Do not open or touch the internal devices and wait five minutes before conducting related operations.
• Please do not install the inverter in humid, greasy, flammable, explosive, dust accumulative, or other severe environments.
• Prohibit reverse connection at the battery input end; otherwise, it will easily damage the equipment or cause unpredictable danger.
• Both utility input and AC output are of high voltage; please do not touch the wiring connection.
• When the fan is working, please do not touch it to avoid injury.

Instructions

Installation steps:
Step1: Professional personnel read this manual carefully.
Step2: Determine the installation location and heat dissipation space.
Move the equipment: as the equipment is relatively large, it is recommended to use a forklift or crane; if the ground is flat, it can be moved by wheels.
Place the equipment: As the equipment is heavy, it is recommended to be placed on flat ground, with 300mm space reserved all around, to ensure heat dissipation.
Fix the equipment: If the optional caster is chosen, rotate counterclockwise to fix and rotate clockwise to move.

WARNING

Risk of explosion! Never install the inverter with flooded batteries in a sealed enclosure! Do not install the WARNING device in a confined area where battery gas can accumulate.

Step3: Takedown the junction box cover plate with special tools.

Step4: Wiring

Wiring order: Ground—-Battery—-Utility—-AC loads

WARNING

Never connect the utility to the inverter output; otherwise, the inverter may be damaged.

Grounding
The voltage of the whole system exceeds the safety voltage level. Thus reliable grounding is needed. The grounding wire shall be the thicker wire no less than 35mm2) and shall be as short as possible. The grounding point shall be as close as possible to the inverter.

CAUTION	When wiring, follow the order to connect the cables to the equipment, then follow the order to connect ground, battery, utility, and load.
WARNING	• Make sure all the wiring connections are reliable; otherwise, massive heat would accumulate at the connection points to damage the terminals or even cause a fire. • Danger, high voltage! Terminals of the Utility input, AC output, and DC input produce high voltage, do not close the breakers during wiring, and ensure each component’s correct polarity.

LCD:

Step11: Turn on the load
LED indicators: Inverter and load indicators are slowly flashing.

CAUTION

• If the power is supplied to the different AC loads, it is suggested to turn on the loads with a larger surge current till the load works well, then turn on the loads with a smaller surge current. Especially for inductive loads, they should be turned on one by one. Do not turn on the loads simultaneously to not cause excessive impact to the inverter, to shorten its life span. • If the inverter is not in regular operation, or LCD or indicator displays abnormal, refer to Section 5 to clear the fault or contact the after-sale service personnel of our company.

Step12: Power off the equipment

1. Disconnect the AC load circuit breaker.
2. Long press the “AC output” button to turn off the inverter output.
3. Disconnect the bypass circuit breaker.
4. Disconnect the battery circuit breaker.
   

   WARNING

   • As electricity exists in the capacitance, the LCD screen would be off after 30 seconds; wait 5 minutes before opening the equipment to repair. • The inverter has a soft stat design and only takes effect when it starts. Do not frequently switch the input circuit breaker when the inverter is incompletely powered off. Otherwise, the input battery would undergo a high current impact. That is, the input circuit breaker can be closed again after the LCD screen is off.

WARNING

After the inverter is disconnected from the utility and battery bank, you must wait 5 minutes before touching the internal conductive devices.

Output voltage/frequency grade switch

When the dial switch 1 is placed to the ON side, the output frequency is 60Hz, otherwise it is 50Hz, When the dial switch 2 is placed to the ON side, the output voltage is 230VAC, otherwise it is 220VAC.
Operating steps:
Open the cover plate on the inverter right side and find the dial switches on the control board, located on the top left corner; see the picture above. Set the output voltage/frequency according to demand, then restart the inverter to take effect.

IMPORTANT

• The factory default output voltage is 220VAC, and the output frequency is 50Hz. • The accessories can refer to the Packing List.

Maintenance

The following inspections and maintenance tasks are recommended at least two times per year for the best performance.

• Make sure no block on airflow around the inverter.
• Clear up any dirt and fragments on the radiator. Check all the naked wires to ensure insulation is not damaged for serious solarization–frictional wear, dryness, insects or rats, etc. Repair or replace some wires if necessary.
• Check and confirm that indicator and display are consistent with required. Pay attention to any troubleshooting or error indication. Take corrective action if necessary.
• 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 the lightning arrester is in good condition. Replace a new one in time to avoid damaging the inverter/charger and even other equipment.
  

  WARNING

  Risk of electric shock! Ensure that all the power is turned off. All the power in the capacitor has been discharged before performing the above operations.
