Format SD Card; Delete Log Data; Delete Settings File; Delete Firmware File.
The SD Card menu offers the following information and functions:
SUMMARY
Status:
• The SD card is detected-not detected
Total Storage:
• Total addressable storage of the SD Card
Space Available:
• Remaining space available on the card
Format SD Card:
• Format the SD Card (FAT32). WARNING: erases all contents on the card and creates system
directories
Delete Log Data:
• Delete log data files from the /log directory only
Delete Settings File:
• Delete configuration settings files saved in the /settings directory
Delete Firmware File:
• Delete firmware update file(s) in the /update directory
LOGGED DATA STORAGE
Use the Setup or Installer Setup Logged Data Storage drop-down to enable internal logging, or
internal and SD Card logging.
There are three different loggers. The daily and hourly Loggers total and record important data
once a day and hourly, respectively. The Event Logger records high-speed operational, network, and
system-level information.
Choose to log data to the GenStar MPPT internal memory only or also allow log data storage on
an SD Card. If the SD card is removed, the GenStar MPPT will continue logging to internal memory
only. By selecting, "Internal and SD Card", and using an SD Card, the maximum amount of logged
data will be substantially increased.
4.2.4 Load Control
(Installer Setup)
By choosing the Standard Button, seven (7) preset load profiles become available. See LiveView
Installer Setup\Load for settings options and values within each setting. Use Copy to Custom to
start a custom profile using preset values. Load High Voltage Disconnect and Reconnect (HVD and
HVR) thresholds can be preset using profiles 5-7. These profiles are useful for batteries that easily
damaged by high voltage.
By choosing the Custom button, the user has full flexibility to enter any desired load control values.
Four (4) customization overlays are available to the right of the Custom button:
2) Time server - if the GenStar MPPT is connected to the Internet, it has the ability to periodically
update time and date from a time server(s). Go to Installer Setup\Network to specify up to three (3)
time server addresses.
4.2.2 Network Settings
(Setup and Installer Setup)
If the GenStar MPPT is connected to a DHCP router, and the DHCP option is selected, network
settings will automatically be assigned. To modify inverter settings remotely over Ethernet, use the
Installer Setup screen section to gain access. If authorized, MODBUS Ethernet writes over Ethernet
will show, “ENABLED”.
Network Settings displays the current network settings configuration.
NOTE:
To change network
settings remotely, first set the unit's on-board meter (Installer Setup) to allow remote writes over
Ethernet.
For security reasons, the, "MODBUS writes over Ethernet" enable/disable setting
can only be modified on the local meter display. This a safety feature to prevent unintended
changes to custom settings, but it is not a replacement for proper network security. This feature
does not block write commands on an EIA-485 network. Never connect units to an open or
unprotected network.
Use the menus to configure:
MODBUS Settings
MODBUS and MODBUS TCP/IP are open standard protocols for communication between connected
devices on serial and Ethernet networks respectively. The GenStar MPPT supports Modbus
communication via serial (EIA-485/RS-232/USB ports) and Ethernet.
MODBUS ID and MODBUS IP Port -
assign IDs as desired
All devices on a Meterbus network must have a unique Meterbus ID. All devices on a serial MODBUS
network must have a unique MODBUS ID. All devices on an Ethernet MODBUS network must have a
unique ID and common MODBUS IP port configuration.
Bridge Ethernet MODBUS TCP/IP requests with MODBUS Serial Messages
An Ethernet MODBUS TCP/IP message with a MODBUS ID that differs from the GenStar MPPT
MODBUS ID will be, "bridged", and sent out as a serial MODBUS message on the GenStar MPPT's
EIA-485, RS-232, and USB serial ports (see Figure 2.3 in Section 2.4). A response from a connected
device on any of those serial networks will be packaged by the GenStar MPPT and sent as a
MODBUS TCP/IP response back to the Ethernet network.
TCP/IPv4
Adjust Ethernet connection parameters.
Time Servers
(Installer Setup)
If the GenStar MPPT is connected to the Internet, it has the ability to periodically synchronize time
and date from a time server. There are three default, public NTP servers, which users can modify as
necessary.
4.2.3 SD Card and Logged Data Storage
(Setup and Installer Setup)
The GenStar MPPT includes an
SD Card
for auxiliary data storage. The SD Card screen will display
the card status, and total available space. Choose one of the four options for data management:
