The inverter achieves the rectification and inversion through a three-phase full-bridge
inverter, and the rectified output is injected into the energy storage battery. The inverter
output is turned into sine wave voltage via the LC filter, then goes through the isolated boost
of three-phase transformer and then is incorporated into the grid power generation or
becomes off-grid power supply to the load.

4Converter Mode and Function
4.1 Model Introduction
4.1.1 Grid-Connected Mode And Off-Grid Mode
Grid-connected
All models of MULTIGRID series energy storage converter can realize grid-connected
function. In the grid-connected mode, the energy storage converter can realize charging and
discharging functions:
1. Charging mode: constant voltage mode, constant current mode, constant power mode.
2. Discharge mode: constant AC power discharge mode.
3. Standby mode: The converter does not work and accepts the start-up instructions at any
time.
Off-Grid Mode
MULTIGRID not only has the function of grid also has from the network function. From the
network mode of operation can be set by the touch screen or PC converter. When set to this
mode converter, AC power supply with constant voltage and frequency converter to the load.
From the network mode including automatic mode and manual mode:
1. automatic mode converter in independent inverter operation state, fault recovery after
converter fault shutdown, when the failure is eliminated without manual operation, the
converter can automatically start and restore the original state.
2. manual mode: refers to the converter in the independent inverter operation state, after the
failure of the converter fault shutdown, when after the restoration of the need of human re set
the starting instruction converter to start independent inverter.
4.2 Energy Storage Converter Function
4.2.1 Basic Function
#Grid-connected operation
The converter directly connected to the grid, can output energy to the grid by the battery,
can also absorb the energy from the grid to charge the battery.
#Off-line Inversion
In the absence of power grid, the energy storage converter can operate independently to
provide load power supply.
#Grid-connected and Off-line switch
This article only for can and from the network switching model in terms of the. The energy
storage converter in grid connected mode, can directly switch the state of charge and
discharge, no need to enter the standby state. The energy storage converter must be in no case
for the grid, the inverter can run independently.
#Redundant Parallel Connection
In large-scale applications, the converter can improve the redundancy, capacity and reliability
of the system through redundant parallel connection.
#Charge and Discharge Control of Energy Storage Batteries

4.2.3 Overheating And Cooling Operation
!The converter operates at set power when IGBT junction temperature is less than 105 C.
!When the junction temperature of IGBT is higher than 105 C, the IGBT will be operated
at a set power percentage.
4.2.4 Cooling System Start-Up
!The air-cooled system will start automatically when the energy storage converter
reaches the rated power or temperature threshold.
4.2.5 Cold Start System
!For off-line operating models, it is necessary to start directly through the battery to
supply power to the load, which can be operated manually.

Status
Description
operation
Normal operation of energy storage converter
Standby
When the converter receives standby instructions from the LCD
screen or the host computer, it turns to standby state in shutdown or
operation mode. When the AC and DC contactors of the converter are
closed in standby state, the system is in hot standby state. When the
LCD screen or the host computer carries out relevant control, the
converter can respond quickly.
fault
When the energy storage system fails, the converter will stop
working, automatically disconnect the contactor on the AC and DC
side, and the main circuit will be disconnected from the battery,
power grid or load. In the fault state, the system always monitors
whether the fault is eliminated or not. If the fault is not eliminated, the
system maintains the fault state. If the fault is eliminated, it will enter
standby state after the default of 30 seconds.!
Shutdown
If the energy storage converter is in the normal "running" state, the
user can stop the energy storage converter by issuing the stop
instruction from the host computer, or Turn off the key through the
LCD screen switch page.
Emergency
shutdown
In case of failure or emergency, press the emergency shutdown button
(EPO) to stop the converter.
Shutdown
Energy Storage Converter All Circuit Breakers Disconnect and
Switch Reset
When the energy storage converter fails or the power module fails, it is forbidden to start
again through the touch screen.
It can be checked by power off to confirm that there is no problem, and then power on again,
otherwise it will cause damage to the machine.
