Operation States
Operation states of the photovoltaic inverter are described as follows: Operating State
STOP
Stop
Stand‐by
RUNNING
AC‐AVR DC‐AVR MPPT Control Grid‐connected Stand‐by
Description ‐ Before initial startup ‐ After MAJOR FAULT occurred ‐ After stop operation Operation is completely stopped. Starting operation is required to move to “Stand‐by” mode. Detection of a MAJOR FAULT results in this state. Typical ‐ At night or sunset situation ‐ After MINOR FAULT or GRID FAULT occurred* The inverter is connected to DC input power and waiting for startup condition establishment. AC output is not connected to the grid (AC Breaker is opened) and the main inverter circuit is gate‐blocked (GB), which means the inverter switching is stopped. Transient state from “Stand‐by” to “DC‐AVR”. The inverter starts generating AC voltage, but not connected to the grid. Transient state from “AC‐AVR” to “MPPT Control” mode. The inverter is connected to the grid. This also includes night SVC operation. Power delivering operation. Energy from PV modules are converted to AC energy and delivered to the grid. DC input voltage is controlled based on Maximum Power Point Tracking (MPPT) control. Typical situation
Temporary state caused mostly by insufficient DC input power. The inverter stops switching, but is connected to the grid.
* : After a Synchronization Loss (MINOR FAULT) or Phase Jump (GRID FAULT), the inverter will go into Grid‐connected Stand‐by mode and not to Stand‐by mode.
When a fault is detected, the inverter will either stop its operation and / or show fault message on the LCD. The faults are categorized in four levels. Fault level ALARM GRID FAULT
MINOR FAULT
MAJOR FAULT
Description Faults which do not affect the operation of the inverter. The inverter will continue to deliver power to the grid. Faults caused by abnormal voltage or frequency of the power grid. The inverter will stop operation and disconnect from the grid. After the abnormal grid condition is cleared, the inverter will restart automatically. Faults which affect normal operation of the inverter caused by temporary abnormal conditions. The inverter will stop operation and disconnect from the grid. After the abnormal conditions are cleared, the inverter will restart automatically. Faults caused by abnormal condition which may damage the inverter. The inverter will stop operation and disconnect both from DC input circuit and the grid. On site operation and detailed check by service personnel are required to reset the system.

2 Basic Communication Specifications
2.1
Communication Procedure
The communication messages between the inverter and the external monitoring and control device are sent in Modbus TCP protocol data type. Mapping, supported function codes, data type and all relevant information regarding the Modbus implementation is included in this document.
2.2
System configuration
The following figure shows an example of the communication system configuration. The inverter is regarded as Modbus slave and the monitoring and control device is regarded as Modbus master. One inverter can respond to a maximum of 3 sessions. Monitoring and SCADA controller Control Device Ex. PLC, Main site controller Skid Skid Controller Controller [Master] [Slave] Communication Communication Communication Board Board Board Photovoltaic Photovoltaic Photovoltaic Inverter Inverter Inverter

Precautions
The Following precautions shall be considered when you configure communication system for monitoring and control. ・Normal and reliable communication is not guaranteed. Differences in communication cable length/location/route may cause disturbance and communication error. ・Surge protective device for communication line or other surge protection shall be installed when necessary. External surge voltage coming from communication line can be cause unexpected failure of the inverter. ・Monitoring and control device (Ex. SCADA system) shall be programed for error handling. Some recommended practices are; plural readings cut off communication by timeout, exclusion of invalid values by checking range of data values, etc. ・This communication function shall never be used for an application where safety of persons rely on. ・This communication function has delay time and shall not be used for an application which requires fast response This delay time is an indeterminate value which is composed from the internal processing delay and external transmission delay of the inverter. The data gotten from plural inverters at the same time are not synchronized. ・The inverter is not a measuring device. The measuring values returned from the inverter shall not be used for the purpose of electricity transaction and efficiency evaluation and other accuracy requested purposes. ・The inverter has no internal radio clock or GPS. The time stamp values may not be accurate. ・Please use this document as a reference. This document is subjected to change without notice.

Description Value = 127 Value = 10 The slope of the reduction in the maximum allowed watts output as a function of frequency. The frequency deviation from nominal frequency (ECPNomHz) at which a snapshot of the instantaneous power output is taken to act as the CAPPED power level (PM) and above which reduction in power output occurs. The frequency deviation from nominal frequency (ECPNomHz) at which curtailed power output may return to normal and the cap on the power level value is removed.

Start/Stop command is not changed Setting of [P limit enable/disable]～[Reactive power Q command or power factor command] cannot be done. = ‘1’ Stop command: Goes to Stop mode when the inverter is in Start mode. If the inverter is in Stop mode, it keeps the Stop mode status. Settings for [P limit enable/disable]～[Reactive power Q command or power factor command] can be done. = ‘2’ Start command: Goes to Start mode when the inverter is in Stop mode. If the inverter is in Start mode, it keeps the Start mode status. Note: There may be other conditions to clear before the inverter effectively starts. Settings for [P limit enable/disable]～[Reactive power Q command or power factor command] can be done. = ‘3’ P limit, Q command or reactive power command: Start/Stop command is not changed Settings for [P limit enable/disable]～[Reactive power Q command or power factor command] can be done. For any value in register 40001, [Time stamp enable/disable][Time stamp] settings can be performed. Enable/disable settings for active power P limit. The inverter output power will follow the MPPT when P limit is disabled. = ‘0’ P limit disable = ‘1’ P limit enable 0.1kW per unit 【Example】 500.0kW 5000 1667.0kW 16670 【Restriction】 The active power may be limited to a lower value depending on the inverter maximum apparent power and the current irradiance (among other parameters).

Description Enable/disable settings for reactive power Q command and power factor command = ‘0’ Q command disable, PF command disable ※inverter should run at power factor 1 = ‘1’ Q command enable, PF command disable = ‘2’ Q command disable, PF command enable Reactive power Q (0.1kVAr per unit): A lagging reactive power is defined as a reactive power that increases the grid voltage and is displayed as a positive value. A Leading reactive power is defined as a reactive power that decreases the grid voltage and is displayed as a negative value. 【Example】 +131.6kvar +1316 ‐131.6kvar ‐1316 +263.3kvar +2633 ‐263.3kvar ‐2633 Power factor command (0.01 per unit): Lagging is defined as a power factor that increases the grid voltage and is displayed as a positive value. Leading is defined as a power factor that decreases the grid voltage and is displayed as a negative value. Note: Negative and positive do not represent a power flow direction. A unity power factor can be set either as 100 or ‐100 【Example】 +1.00 : +100 ‐1.00 : ‐100 +0.95 : +95 ‐0.95 : ‐95 【Restriction】 The following two items will take priority over both reactive power Q command and power factor command 1) Power factor range (0.85 to 1.00 for both leading and lagging power factors). 2) Maximum apparent power of the inverter. Therefore, it may occur that the reactive power command and the power factor command are not followed in order to keep the system within the limits established in 1) and 2). = ‘0’ Time Stamp Disabled = ‘1’ Time Stamp Enabled Time stamp value for the inverter is set in registers 40007～40010. = ’C’ Reserved (Can not be used)
