tracking or multiple parallel MPPTs tracking. The PV maximum input current can be increased from 15A to 30A. When connecting two or more PV arrays separately or in parallel, set the “PV mode” as “ALL SINGLE” or “ALL MULTIPLE” on the LCD according to the actual connection. When two or more PV arrays are independently input, set the “PV mode” as “ALL SINGLE.” When two or more PV arrays connected in parallel to one access to the inverter/charger (the PV terminals of the inverter/charger need to be paralleled externally), set the “PV mode” as “ALL MULTIPLE.” When there is only one PV array, the “PV mode” is “ALL SINGLE” by default, other PV modes are invalid. When connecting a non- inverter generator, the charging current maybe cannot reach the rated power. It is recommended to connect an inverter generator. And when using the generator, the “AC Input mode” needs to be set to the “Generator.” For the specific setting method, refer to chapter 2.5.1 Parameters list.

3 Installation
3.1 Attention
Please read the manual carefully to familiarize yourself with the installation steps. Be very careful when installing the batteries, especially flooded lead- acid batteries. Please wear
eye protection, and have fresh water available to rinse if contact with battery acid. Keep the battery away from any metal objects, which may cause a short circuit of the battery. During the charging of the battery, acidic and flammable gases may be produced, it is important
to ensure that the surrounding environment is well ventilated. This inverter/charger is wall-mounted. Consider whether the wall’s bearing capacity can meet the
requirements. Ventilation is highly recommended if mounted in an enclosure. Never install the inverter/charger
in a sealed enclosure with flooded batteries! Battery fumes from vented batteries will corrode and destroy the inverter/charger circuits. The inverter/charger can work with lead-acid and lithium batteries within its control scope. Ensure all switches and breakers are disconnected before wiring. You operate the inverter/charger after checking that all wiring is correct. Loose connections and corroded wires may produce high heat that can melt wire insulation, burn surrounding materials, or even cause a fire. Ensure tight connections, use cable clamps to secure cables, and prevent them from swaying in motion. Select the system connection cables according to the current density no greater than 5A/mm2. Do not install the inverter/charger in a harsh environment such as flammable, explosive, or dust accumulative. After turning off the switch, high voltage still exists inside the inverter/charger. Do not open or touch the internal devices; wait ten minutes before conducting related operations. Although the battery input terminal has reverse polarity protection, which only take effect without PV and Utility connection; please do not operate it in error frequently. Utility input and AC output are high voltage. Please do not touch the wiring connection. When the fan is working, please do not touch it to avoid injury.
3.2 Wire and breaker size
The wiring and installation must conform to all national and local electrical code requirements.
48

Recommended PV wire and breaker size

Since the PV output current varies with the PV module’s size, connection method, or sunlight angle, the minimum wire size can be calculated by the PV Isc (Max. short circuit current). Please refer to the Isc value in the PV module’s specifications. When the PV modules are connected in series, the total Isc equals any PV module’s Isc. When the PV modules are connected in parallel, the total Isc equals the sum of the PV module’s Isc. The PV array’s Isc must not exceed the maximum PV input current. For max. PV input current and max. PV wire size, please refer to the table below:

WARNING

Connect the battery circuit breaker first. After the inverter/charger normally works, connect the PV array and the utility input plug. Otherwise, we won’t assume any responsibility for not following the operation.
The AC output is ON by default after the inverter/charger is powered. Before turning on the power switch, ensure the AC output is connected to loads correctly, and no safety hazard exists.

Step 4: Set parameters by the buttons.

For detailed parameters setting, refer to chapter 2.5 Parameters setting. CAUTION

Step 5Use the inverter/charger.

Connect the load circuit breaker, the PV array circuit breaker, and the utility input plug in sequence. After the AC output is normal, turn on the AC loads one by one. Do not turn on all the loads simultaneously to avoid protection action due to a large transient impulse from the current. The inverter/charger will perform normal work according to the set working mode. See chapter 2.4 Interface.

CAUTION

When supplying power for different AC loads, turning on the load with a larger impulse current first is recommended. After the load output is stable, turn on the load with a smaller impulse current later.

6 Troubleshooting

CAUTION

After the inverter/charger is powered on, the meter displays the boot screen all the time (unable to enter the home screen) and the red “RUN” indicator flashes. It means the communication with the inverter/charger is error. When the above fault occurs, check whether the communication cable is disconnected. If not, don’t hesitate to contact our after-sales engineer.

Solution

Disconnect the charging connection, and check whether the battery

voltage is too high. Verify if the actual battery voltage matches the rated

battery voltage; or check if the “over voltage disconnect voltage” is

inconsistent with the battery specifications. After the battery voltage

drops below the set value of “over voltage reconnect voltage”, the alarm

will automatically be cleared.

Disconnect the loads connection, and check whether the battery voltage

—

is too low. After the battery voltage is charged and restored to above the

“low voltage reconnect voltage”, it will automatically return to normal, or

use other methods to charge the battery.

Ensure the battery is installed in a cool and well-ventilated place, check

that the battery actual charging and discharging current does not exceed

the setting values of “Battery Max. charging current ” and “Battery limit

discharging current.” It resumes normal work when the battery cools

down to below the “Battery over temperature protect recover.”

7 Maintenance

The following inspections and maintenance tasks are recommended at least twice yearly for best performance. Make sure no block on airflow around the inverter/charger. Clear up dirt and fragments on the
radiator. Check all the wired cables 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 LED or LCD is consistent with the required. Pay attention to any
troubleshooting or error indication. Take necessary corrective action. Confirm that all the terminals have no corrosion, insulation damage, 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 other equipment.

WARNING

Risk of electric shock! Turn off all the power before the above operations and follow the corresponding inspections and operations.
