Operating Modes

4.1 Charging Mode
1. Solar First: Priority shall be given to charging by PV, and mains charging will be started only when the PV has failed. It can fully utilize solar energy to generate power in the daytime and then switch to mains charging to keep the battery level, and can be used in regions where the grid is relatively stable and the feed-in tariff is relatively expensive.
2. Mains First: Priority shall be given to charging by Mains Power, and charging with PV power will be started only when the Mains has failed.
3. Hybrid Charging: Hybrid charging of PV and Mains Power, give priority to PV MPPT charging, and supplement Mains Power when PV energy is insufficient. When the PV energy is sufficient, the Mains Power will stop charging. This is the mode of fast charging and suitable for unstable areas of power grid, and can provide sufficient backup power at any time.
18

4. Only Solar: Only PV charging, no mains charging is initiated. This is the most energy-efficient mode and the battery power comes from solar energy, which is usually used in regions with good daylighting conditions.
4.2 Output Mode
1. Solar First: PV and battery will power the load, with diversified charging modes available and output mode optional, when the Solar First Mode is selected, the use of green solar energy can be maximized for energy efficiency and emission reduction. Switch to Mains Power when PV has failed. This mode can maximize the use of solar energy while maintaining the battery power, which is suitable for regions with relatively stable power grid.
2. Mains First: Switch to inverter power supply only when Mains Power has failed, which is equivalent to backup UPS and is used in regions with unstable power grid.
19

3. Inverter First: Switch to Mains Power supply only when the battery is under-voltage. This mode uses DC energy to the maximum extent and is used in regions with stable power grid.
4. Hybrid output and gird connection: (need to be abled) In the utility bypass state, when no battery is connected or when the battery is full, the load power is supplied by the PV and the utility together if the hybrid function is enabled, and the surplus PV energy is fed back to the grid if the grid connection function is enabled.

Other Functions

6.1 Dry Contact
Working principle: This dry contact can control the ON/OFF of the diesel generator to charge the battery. 1. Normally, the terminals are that the NC-N point is closed and the NO-N point is
open; 2. When the battery voltage reaches the low voltage disconnection point, the relay
coil is energized, and the terminals turn to that the NO-N point is closed while NCN point is open. At this point, NO-N point can drive resistive loads: 125VAC/1A, 230VAC/1A, 30VDC/1A.
6.2 RS485 Communication Port
This port is an RS485 communication port which comes with two functions: 1. RS485-2 allows direct communication with the optional host computer
developed by our company through this port, and enables monitoring of the equipment running status and setting of some parameters on the computer; 2. RS485-1/RS485-2 also allows direct connection with the optional RS485 to WiFi/GPRS communication module developed by our company through this port. After the module is selected, you can connect the all-in-one solar charge inverter through the mobile phone APP, on which you can view the operating parameters and status of the device. As shown in the figure: RS485-1: Pin 1 is 5V power supply, Pin 2 is GND, Pin 7 is RS485-A1, and Pin 8 is RS485-B1; RS485-2: Pin 1 is 5V power supply, Pin 2 is GND, Pin 7 is RS485-A2, and Pin 8 is RS485-B2;
6.3 USB Communication Port
This is a USB communication port, which can be used for USB communication with the optional PC host software. To use this port, you should install the corresponding “USB to serial chip CH340T driver” in the computer.
39

6.4 Parallel Communication Function (Parallel Operation Only)

a) This port is used for parallel communication, through which the parallel modules can

communicate with each other. b) Each inverter has two DB15 ports, one for the male connector and the other for the female
connector. c) When connecting, make sure to connect the male connector of the inverter with the female

connector of the inverter to be paralleled, or connect the female connector of the inverter to the

male connector of the inverter to be paralleled. d) Do not connect the male connector of the inverter to its female connector.

10 Parallel Installation Guide

10.1 Introduction

1. Up to six units connected in parallel.

2. When using the parallel operation function, the following connecting lines (package accessories)

shall be firmly and reliably connected:

DB15 Parallel communication line*1:

Current sharing detection line*1:

10.2 Precautions for Connecting the Parallel Connecting Lines WARNING
1. Battery wiring: Parallel connection in single or split phase: Ensure that all all-in-one solar charger inverters are connected to the same battery, with BAT + connected to BAT +, BAT – connected to BAT-, and that the connection is correct with the same wiring length and line diameter before power on and startup, so as to avoid the abnormal operation of parallel system output caused by wrong connection. 2. AC OUT wiring: Parallel connection in single phase: Ensure L-to-L, N-to-N and PE-to-PE connection for all all- inone solar charger inverters, and that the connection is correct with the same wiring length and line diameter before power on and start-up, so as to avoid the abnormal operation of parallel system output caused by wrong connection. For specific wiring, please refer to 2.4.3 Wiring Diagram Parallel connection in split phase: Ensure N-to-N and PE-to-PE connection for all all-in-one solar charger inverters. The L lines of all inverters connected to the same phase need to be connected together. But L lines of different phases cannot be joined together. Other connection precautions are the same as parallel connection in single phase. For specific wiring, please refer to 2.4.4Wiring Diagram

AC IN wiring: Parallel connection in single phase: Ensure L-to-L, N-to-N and PE-to-PE connection for all all- inone solar charger inverters, and that the connection is correct with the same wiring length and line diameter before power on and start-up, so as to avoid the abnormal operation of parallel system output caused by wrong connection. Meanwhile, it is not allowed to have multiple different AC source inputs to avoid damage to the external equipment of the inverter. The consistency and uniqueness of AC source input shall be ensured. For specific wiring, please refer to 2.4.3 Wiring Diagram. Parallel connection in split phase: Ensure N-to-N and PE-to-PE connection for all all- in-one solar charger inverters. The L lines of all inverters connected to the same phase need to be connected together. But L lines of different phases cannot be joined together. Other connection precautions are the same as parallel connection in single phase. For specific wiring, please refer to 2.4.4 Wiring Diagram. 4. Wiring of parallel communication line: Parallel connection in single or split phase: Our company’s parallel communication line is a DB15 standard computer cable with shielding function. Ensure the “one-in- one-out” rule when connecting each inverter, that is, connect the male connector (out) of this inverter with the female connector (in) of the inverter to be paralleled. Do not connect the male connector of the inverter to its female connector. In addition, make sure to tighten the parallel communication line of each inverter with self-contained end screws of DB15 to avoid the abnormal operation or damage of the system output caused by the falling off or poor contact of the parallel communication line. 5. Wiring of current sharing detection line: Parallel connection in single phase: Our company’s current sharing detection line is a twisted connection line. Ensure the “one-in-one-out” rule when connecting each inverter, that is, connect the current sharing line of the inverter with the current sharing green port of the inverter to be paralleled (choose one port from the two, and there is no mandatory sequence requirement). The current sharing ports of the inverter cannot be connected to each other. In addition, make sure that the red and black current sharing connection lines of each inverter are not manually exchanged, and make sure to tighten the lines with self-contained screws to avoid the abnormal operation or damage of the system output caused by abnormal parallel current sharing detection. For specific wiring, please refer to 2.4.3 Wiring Diagram. Parallel connection in split phase: The current sharing detection lines of all inverters connected

to the same phase need to be connected together. But the current sharing detection lines of different phases cannot be joined together. Other connection precautions are the same as parallel connection in single phase. For specific wiring, please refer to 2.4.4 Wiring Diagram. 6. Before or after connecting the system, please carefully refer to the following system wiring
diagram to ensure that all wiring is correct and reliable before power on. 7. After the system is wired, powered on and in normal operation, if a new inverter needs to be
connected, make sure to disconnect the battery input, PV input, AC input and AC output, and that all all-in-one solar charger inverters are powered off before reconnecting into the system.

NOTICE

1. Before starting up and running, please check whether the connection was correct to avoid any abnormalities in the system.
2. All wiring must be fixed and reliable to avoid wire drop during use. 3) When the AC output is wired to the load, it shall be properly wired according to the
   requirements of the electrical load equipment to avoid damage to the load equipment. 4) Settings [38] need to be set consistently or only for the host. When the machine is running, the
   voltage set by the host shall prevail, and the master will force the rewrite of the other slave machines to keep the same set. Only can be set in the standby mode. 5) Machine factory default for single machine mode, if you use parallel, split-phase or threephase function, you need to set the [31] item parameters through the screen. The setting method is: power on one machine at a time, the rest of the machine off, and then set the [31] item parameters according to the site system operation mode. After this machine is set successfully, turn off the machine switch and wait for the machine to be powered down, then set the rest of the machines in turn until all machines are set, and then all machines are powered up again at the same time and enter the working state. The [31] setting item: When in single phase parallel connection: setting 31should be set as PAL When in single phase parallel connection, setting 31 should be set as follows When in three phase parallel connection, all machines in phase 1 must be set as 3P1, all machines in phase 2 must be set as 3P2 all machines in phase 3 must be set as 3P3, at present, the voltage phase difference between P1-P2, P1-P3 and P2-P3 is 120 degrees. When the output voltage set in the setting 38 is 120 Vac (U model), the line voltage between L1 in phase 1 and L2 in phase 2 is 1201.732 = 208 Vac, similarly the line voltage between L1-L3, L2-L3 is 208 Vac; the single phase voltage between L1-N, L2-N, L3-N is 120Vac. In split phase parallel connection, all connected P1-phase inverters are set to “2P0” i. If all connected P2-phase inverters are set to “2P1”, AC output line voltage difference is 120
   degrees (L1-L2), line voltage is 1201.732= 208Vac; Phase voltage is 120Vac (L1-N; L2-N). ii. If all connected P2-phase inverters are set to “2P2”, AC output line voltage difference is 180
   degrees (L1-L2), line voltage is 120*2= 240Vac; Phase voltage is 120Vac (L1-N; L2-N). 6) After the system runs, the output voltage is measured correctly, and then the load setting is
   connected.
