Without the authorization of our company, you may not open the inverter cover or replace the inverter parts, otherwise the warranty promise of the inverter will be invalid. The use and operation of the inverter must be carried out in accordance with the instructions in this manual, otherwise this protection will fail and the warranty of the inverter will also fail. During working, the inverter surface temperature may exceed 60°C, please make sure the inverter cools down before touching, and make sure children can not touch. When exposed to sunlight, photovoltaic arrays generate dangerous high DC voltages. Please follow our instructions, otherwise it will be life- threatening. All DC and AC power sources must be disconnected from the inverter for at least 5 minutes before any wiring or electrical operation is performed on the inverter to ensure complete isolation of the inverter and avoid electric shock.
05

A photovoltaic module used on the inverter must have a IEC61730A rating, and the total open circuit voltage of the photovoltaic string / array is lower than the maximum rated DC input voltage of the inverter. Any damage caused by photovoltaic over voltage is not covered by warranty. Installation position should be away from wet environment and corrosive substances. After the inverter and power grid cut off the PV power supply, there will be a certain amount of residual current in a short time, be cautious or it may lead to serious personal injury and even high risk of death.Use a multimeter (impedance at least 1 M) to measure the voltage between the UDC + and the UDC- to ensure that the inverter port is discharged below the safe voltage before starting operation (35 VDC).
Ø Surge protection devices (SPDs) for PV installation Warning! Over-voltage protection with surge arresters should be provided when the PV power system is installed. The grid connected inverter is fitted with SPDs in both PV input side and MAINS side.
Direct or indirect lightning strikes can cause failures. Surge is the main cause of lightning damage to most devices. Surge voltage may occur at photovoltaic input or AC output, especially in remote mountain areas where long distance cable is supplied. Please consult professionals before installing SPDs. The external lightning protection device can reduce the influence of direct lightning strike, and the lightning protection device can release surge current to the earth.
06

Safety If the building installed with external light protection device is far away from the inverter location, in order to protect the inverter from electrical and mechanical damage, the inverter should also install an external lightning protection equipment. In order to protect DC system, two-stage surge protection equipment is needed between DC cable of inverter and photovoltaic equipment module. In order to protect the AC system, the level 2 surge protection equipment should be installed at the AC output, located between the inverter and the grid. Installation requirements must comply with IEC61643-21 standard. All DC cables shall be installed in a distance as short as possible, and the positive and negative cables of the same input need to be bundled together to avoid causing loops in the system. Minimum distance installation and binding requirements also apply to auxiliary grounding and shielding grounding conductors.
07

Ø Anti-lslanding Effect The islanding effect means that when the power grid is cut off, the grid-connected power generation system fails to detect the power outage and still supplies power to the power grid. This is very dangerous for the maintenance personnel and the power grid on the transmission line.
This inverter use active frequency offset method to prevent islanding effect.
Ø PE Connection and Leakage Current · All inverter’s incorporate a certified internal Residual Current Monitoring (RCM) in order to protect against possible electrocution and fire hazard in case of a malfunction in the PV array, cables or inverter. There are 2 trip thresholds for the RCM as required for certification (IEC 62109-2:2011). The default value for electrocution protection is 30 mA, and for slow rising current is 300 mA.
· If an external residual current device (RCD) (type A is recommended) is
mandatory, the switch must be triggered at a residual current of 300 mA (recommended). RCD of other specif cations can also be used according to local standard.

Introduction

3.3 Work Modes

Forced charging

6:00

24:00 The inverter has two settable working periods:

Allowed discharging

12:00

allowed discharging period and forced charging period. 18:00

For how to set the two working periods, please refer to page 92.

The default value of allowed discharging period is 00:00~23:59, and the

default value of forced charging period is 00:00~00:00 (closed in default).

You can set the two working periods by yourself.

As shown in the example above, the allowed discharging period is 6 am to

24 pm, and the forced charging period is 24 pm to 6 am.

· Forced charging period The priority of forced charging period is higher than all work modes. Under the forced charging period, the inverter will charge the battery rst until the battery SOC reaches the value of “charge battery to”.

· Allowed discharging period Under the allowed discharging period, the inverter will allow the battery to discharge (but not force the battery to discharge). The following work modes will take effect under the allowed discharging period.

For on-grid status, there are five work modes: Self Use, Feed-in Priority, Backup, Manual and Peak shaving mode.

Self Use

The self-use mode is suitable for areas with low feed-in subsidies and high electricity prices. The power of PV will supply the loads rst, and surplus power will charge the battery, then the remaining power will feed into the grid.

Priority: Loads Battery Grid

Feed-in priority

The feed-in priority mode is suitable for areas with

high feed-in subsidies, but has feed-in power

limitation.

The power of PV will supply the loads rst, and surplus

power will feed into the grid, then the remaining

power will charge the battery.

Priority: Loads Grid Battery

16

Introduction

Backup mode

The back-up mode is suitable for areas with frequent power outages. This mode will maintain the battery capacity at a relatively high level, to ensure that the emergency loads can be used when the grid is off. Same working logic with “Self-use” mode.

Priority: Loads Battery Grid

• For the above three work modes, when the power of PV is insufficient to supply the loads, the battery will supply the loads. If the battery is insufficient, then the grid will supply the loads.
  Manual This work mode is for the after-sales team to do after-sales maintenance.

For off-grid status, there is only one work mode: EPS (Off-grid).

EPS (Off-grid)

In case of power failure, the system will supply EPS loads through PV and battery. (The battery must be installed, and EPS loads shall not exceed battery’s max. output power.) The power of PV will charge the loads rst, and surplus power will charge the battery.
Priority: Loads Battery

Note: The battery will stop discharging when SOC=min SOC. But due to battery self consumption, sometimes SOC may min SOC.
For on-grid status, if the battery SOC (min SOC-5%), the inverter will take utility energy to charge battery SOC back to (min SOC+1%).
For off-grid status, if the battery SOC min SOC, the inverter will be unable to enter EPS mode (the battery will be unable to discharge) unless SOC is back to 31%.

Dmidnight

The D-A period is the battery charging period during which discharging is not allowed and the PV will charge the battery rst for peak shaving. The ChargeFromGrid” setting determines whether or not to charge from the grid. When “ChargeFromGrid” is set to “Disable”, the battery cannot charge from the grid; when “ChargeFromGrid” is set to “Enable” and the actual battery SOC is less than “Max_SOC”, the battery will charge from the grid at no more than “ChargePowerLimits” power.
In the A-B and C-D periods, if the power of loads does not exceed “PeakLimits”, the PV will charge the battery rst.When the battery is fully charged, the PV will charge loads, and the surplus power will feed into the grid. If the power of loads exceeds “PeakLimits”, the PV and battery will discharge energy for loads and thus reduce the amount of energy purchased from the grid.
In the B-C period, the battery does not discharge. The PV will charge the battery to the “Reserved SOC” rst and then supply power or loads, with the surplus power feeding into the grid. Charging the battery rst in these peiods is storing energy for the peak shaving.

• If there are requirements for zero output from the inverter, the PV output will be limited.

Introduction
3.4 Micro Grid Introduction
There are a large number of traditional on-grid inverters on the market. Due to Islanding Effect, on-grid inverters are unable to work during offgrid. This feature makes users lose the on-grid inverter PV energy when off-grid. Micro- grid is a function that makes hybrid inverter simulate the grid to active on- grid inverter during off-grid. By connecting on-grid inverter to the EPS port of hybrid inverter, hybrid inverter is able to use PV or battery energy to active on-grid inverter when utility lost.

Ø Parallel Control Function Master inverter has an absolute lead in the parallel system to control slave inverter’s energy management and dispatch control. Once master inverter has some error and stop working, slave inverter will be stop simultaneously. But master inverter is independent of slave inverter to work and will not be affected by slave inverter’s fault. Overall system will be running according to master inverter’s setting parameters, and most setting parameters of slave inverter will be kept but not be cancelled. Once slave inverter exit from system and be running as an independent unit, its all setting will be re-excuted. The rest of this section covers several important parallel control functions, and the next page table shows which LCD options are controlled by master inverter and which can work independently. Off mode setting: Off mode can only be set by master inverter ( long press ESC button on LCD ). Safety setting: System safety protection is cancelled by master inverter’s safety. Slave inverter protection mechanism will only be triggered by master inverter’s instructions. Self-use setting: If system is running as self-use mode, please note the Feedin Power Limit set of master inverter is for the overall system and the corresponding set of slave inverter is invalid. Power Factor setting: All sets about power factor are all for the overall system and the corresponding sets of slave inverter are invalid. Remote control setting: The remote demand instructions received by master inverter will be interpreted as the demand instructions to overall system.

Peak Shaving

For on-grid status, there are five work modes: Self Use, Feed-in Priority, Backup, Manual. and Peak shaving mode.

Self Use

The self-use mode is suitable for areas with low feed-in subsidies and high electricity prices. The power of PV will supply the loads rst, and surplus power will charge the battery, then the remaining power will feed into the grid.
Priority: Loads Battery Grid

Feed-in priority

The feed-in priority mode is suitable for areas with high feed-in subsidies, but has feed-in power limitation. The power of PV will supply the loads rst, and surplus power will feed into the grid, then the remaining power will charge the battery.

Priority: Loads Grid Battery

Backup mode

The back-up mode is suitable for areas with frequent power outages. This mode will maintain the battery capacity at a relatively high level, to ensure that the emergency loads can be used when the grid is off. Same working logic with “Self-use” mode.

Priority: Loads Battery Grid

82

Setting

• For the above three work modes, when the power of PV is insufficient to supply the loads, the battery will supply the loads. If the battery is insufficient, then the grid will supply the loads.

Manual This work mode is for the after-sales team to do after-sales maintenance.

Manual mode (manual mode), there are three options to choose from: forced charging, forced discharge, stop charging and discharging (grid-connected 0 power).

Work Mode

Manual Forced Discharge

Manual Forced Charge

Work Mode >Manual
Stop Chrg&Dischrg

For off-grid status, there is only one work mode: EPS (Off-grid).

EPS (Off-grid)

In case of power failure, the system will supply EPS loads through PV and battery. (The battery must be installed, and EPS loads shall not exceed battery’s max. output power.) The power of PV will charge the loads rst, and surplus power will charge the battery.
Priority: Loads Battery

Note: The battery will stop discharging when SOC=min SOC. But due to battery self consumption, sometimes SOC may min SOC. For on-grid status, if the battery SOC (min SOC-5%), the inverter will take utility energy to charge battery SOC back to (min SOC+1%). For off-grid status, if the battery SOC min SOC, the inverter will be unable to enter EPS mode (the battery will be unable to discharge) unless SOC is back to 31%.

The D-A period is the battery charging period during which discharging is not allowed and the PV will charge the battery rst for peak shaving. The ChargeFromGrid” setting determines whether or not to charge from the grid. When “ChargeFromGrid” is set to “Disable”, the battery cannot charge from the grid; when “ChargeFromGrid” is set to “Enable” and the actual battery SOC is less than “Max_SOC”, the battery will charge from the grid at no more than “ChargePowerLimits” power.
In the A-B and C-D periods, if the power of loads does not exceed “PeakLimits”, the PV will charge the battery rst.When the battery is fully charged, the PV will charge loads, and the surplus power will feed into the grid. If the power of loads exceeds “PeakLimits”, the PV and battery will discharge energy for loads and thus reduce the amount of energy purchased from the grid.
In the B-C period, the battery does not discharge. The PV will charge the battery to the “Reserved SOC” rst and then supply power or loads, with the surplus power feeding into the grid. Charging the battery rst in these peiods is storing energy for the peak shaving.

• If there are requirements for zero output from the inverter, the PV output will be limited.

8. Peak Shaving mode

This setting is for enabling peak shaving mode. “DisChgPeriod1” and “DisChgPeriod2” are two discharging periods you can set. Set “ShavingStartTime1” (default value: 7:00) and “ShavingEndTime1 (default value: 15:00) under “DisChgPeriod1” , and “ShavingStartTime2 (default value: 19:00) and “ShavingEndTime2″ (default value: 23:00) under .”DisChgPeriod2” to define the peak hours of electricity. Set “PeakLimits1/2” to limit the power that loads get from the grid. Once the power of loads exceeds “peak limits” during the peak hours, the PV and battery will discharge energy for loads and thus reduce the amount of energy purchased from the grid. In non-peak hours, discharging of the battery is not allowed. If you want to get electricity from the grid, set “ChargeFromGrid” to “Enable”. “Disable” is the default setting. When you select “Enable” and the actual battery SOC is less than “MAX_SOC “(settable), the battery can be charged from the grid at no more than “ChargePowerLimits” (settable) power. Range of “ChargePowerLimits”: 0 W~rated power (W) The range of “MAX_SOC” is 10%­100%; the default value is 50%. Range of “Reserved_SOC” is10%­100%; the default value is 50%. “Reserved_SOC” is the battery capacity saved for the next peak shaving in the non-peak shaving period.
