Wire specification and breaker type
For wiring and installation ways,it is required to observe national and local electrical specification requirements. Recommended wiring specification and breaker type for photovoltaic array: the output current of the photovoltaic array is affected by the form, connection way and illumination angle of the photovoltaic array, therefore the minimum wire diameterof the photovoltaic array is calculated based on the short circuit currentof photovoltaic array. Please refer to the short circuit current value in the specification of the photovoltaic array (the short circuit current keeps unchanged for the photovoltaic arrays in series connection; the short circuit current of photovoltaic arrays in parallel connection s the sum of short circuit current of all components connected in parallel); the short circuit current of the array cannot exceed maximum nput current of PV.

Note: above wire diameter and breaker are only for reference. Please select appropriate wire diameter and breaker based on practical condition.

Installation and Wiring

Installation step:

Step 1: confirm the installation position and heat dissipation space, confirm the installation position of the solar charge inverter, such as wall surface; to install the solar charge inverter, guarantee there is sufficient air flowing through the cooling fins of solar charge inverter. At least reserve 200mm space at the left and right air outlets of the solar charge inverter to guarantee heat loss through natural convection. Refer to the overall installation schematic above.

Warning: danger of explosion! Never install the solar charge inverter and lead-acid liquid battery into the same sealed space or in a sealed place with probable accumulation of battery gas.

Step 2: Remove the terminal protection cover

Step 3: wiring

AC input/output wiring method:

1. Before AC input/output wiring, disconnect the external breaker at first and then confirm whether the cable used is thick enough. Please refer to chapter “ 2.2 Wiring Specification and Breaker type”;
2. Correctly connect AC input wire in accordance with cable sequence and terminal position shown in the figure below. Please connect ground lead at first, and then live wire and mull wire;
3. Correctly connect AC output wire in accordance with cable sequence and terminal position shown in the figure below. Please connect the ground wire at first, and then live wire and null wire. The ground wire is connected to the ground screw hold through Oshaped terminal.

Note: use thick ground cable as far as possible (with cable section not less than 4mm2), place the ground point to be close to the solar charge inverter as far as possible and choose shorter ground wire to the greatest extent Wiring method of PV input:

1. Before wiring, disconnect external breaker at first, and confirm whether the used cable is thick enough. Please refer to chapter “2.2 Wiring Specification and Breaker Type”;
2. Correctly connect PV input wire in accordance with cable sequence and terminal position shown in the figure below.

BAT wiring method:

1. Before wiring, disconnect external breaker at first, and then confirm whether the used cable is thick enough. Please refer to chapter “ 2.2 Wiring Specification and Breaker Type ” . BAT wire shall be connected with the machine via O-shaped terminal. It is recommended to use the O-shaped terminal with 5mm inside diameter. The O-shaped terminal must compress BAT wire firmly to prevent excessive heating caused by great contact resistance;
2. Correctly connect BAT wire in accordance with cable sequence and terminal position shown in the figure below.

Warning notice:

1. Input from mains supply, AC output and photovoltaic array may generate high voltage. Before wiring, make sure to break the breaker or fuse;
2. During wiring process, make sure to pay attention to the safety; during the wiring process, please don’t close the breaker or fuse. At the same time, guarantee that “+” and “-” poles of different parts are correctly connected with wires; a breaker must be installed at the battery end and selected based on chapter “2.2 Wiring Specification and Breaker Type”. Before wiring, make sure to break the breaker to prevent strong electric spark generated during wiring. At the same time, avoid battery short circuit during the wiring process; if the solar charge inverter is in the area with frequent thunder, it is suggested to install an external arrester at PV input terminal.

Step 4: inspect whether the wires are correctly and firmly connected, especially whether the positive and negative input poles of the battery are correct, whether the positive and negative input poles of PV are correct, whether AC input is inaccurately connected to AC output terminal.

Step 5: install protective cap of terminal

Step 6: Start solar charge inverter

At first close the breaker at the battery end, and then press the rocker switch at the lower left side of the machine to “ ON ” state, “ AC/INV ” indicator light flashes, indicating normal operation of inverter. Afterwards, close breakers of photovoltaic array and mains supply. In the end, after AC output is normal, turn on AC load one by one to avoid protection action generated by great instant impact owing to simultaneous turnon of loads. The solar charge inverter operates normally in accordance with set mode.

Note: if power is supplied to different AC loads, it is suggested to turn on the loads with great impact current, and then turn on the load with little impact current after the load operates stably.

Note: in case of abnormal operation of solar charge inverter or abnormal display of LCD or indicator light, refer to Chapter 6 for troubleshooting.

Operating Mode

Charge mode

1. Photovoltaic priority: in photovoltaic priority charge mode, mains charge is started only when the photovoltaics is out of work. Make full use of solar energy for power generation in the daytime and transfer to the mains supply for the charge to maintain the electric quantity of the battery. It is suitable for areas with relatively stable power grid and relatively expensive electricity prices.
2. Mains supply priority: mains supply is to charge the battery preferentially and the photovoltaic charge can be started only when the mains supply is valid.
3. Mixed charge: with mixed charge through photovoltaics and mains supply, photovoltaic MPPT charge is used preferentially. In case of insufficient photovoltaic energy, the mains supply is used for supplement. In case of sufficient photovoltaic energy, mains supply stops charge. Electricity can be charged fastest with the way, which is suitable for the area with unstable power grid, so as to supply sufficient backup power supply at any time.
4. Only solar: only photovoltaic charge is used, no mains supply is started. This way can save energy at most. The electric energies of battery are all from solar energy. This way is suitable for areas with good light conditions.

Output mode

Photovoltaic priority mode : Photovoltaic and battery supply power to the load. With diversified charge mode and optional output mode, when photovoltaic priority mode is selected, green solar energy can be used as far as possible so as to achieve energy conservation and emission reduction. It switches to mains supply when the photovoltaics is invalid. With this mode, solar energy can be used maximally and electric quantity can be maintained at the same time. Therefore, the mode is suitable for areas with stable power grid .

Mains supply priority mode: it only switches to inverter for power supply when mains supply is invalid, equivalent to a backup UPS. Therefore, the mode is applicable to area with unstable power grid.

Inverter priority mode: it only switches to the mains supply in case of an Undervoltage of battery. With this mode, DC electric energy is used maximally. Therefore, it is applied to the area with a stable power grid .

Other Function

Dry node function
Working principle: this dry node can control the switch of diesel generator to charge the battery.

1. Under normal conditions, in this terminal, NC-N point is closed and NO-N point is opened;
2. when the battery voltage reaches the low-voltage disconnection voltage point, the coil of the relay is energized and NO-N point is closed and NC-N point opened. At this time, NO-N point can drive resistive loads 125VAC/1A, 230VAC/1A and 30VDC/1A.

System Maintenance

• In order to maintain the optimum and permanent operation performance, it is suggested to check the following items semiannually.

1. Confirm that the airflow around the solar charge inverter will not be blocked. In addition, remove any dirt or debris from the radiator.
2. Check whether the insulation of all exposed wires is damaged due to sun exposure, friction with other objects around, dry rot, insect or rat damage, etc. If necessary, it is required to repair or replace the wires.
3. Verify that the indication and display are consistent with the operation of the device. Please pay attention to any faults or errors display and take corrective measures if necessary.
4. Check all terminals for corrosion, insulation damage,high temperature or burning/discoloration sign, and tighten the terminal screws.
5. Check for dirt, nesting insects, and corrosion phenomena and clean as required.
6. If the arrester has failed, replace the failed arrester in time to protect the solar charge inverter and another user device against lightning damage.

Warning: Danger of electric shock! To perform the above operations, make sure that all the power supplies of the solar charge inverter have been broken and all the capacitor electricity has been discharged. Afterward, a corresponding inspection or operation can be performed!

We are not responsible for any following damage:

1. Damage caused by improper use or use in inappropriate place.
2. The open-circuit voltage of the photovoltaic module exceeds the maximum allowable voltage.
3. The damage caused by the operation’s ambient temperature beyond the limited operating temperature range.
4. Personally take apart and maintain the solar charge inverter.
5. Damage caused by force majeure: damage caused by transportation and handling of the solar charge inverter.
