The actions include saving files, broadcast, etc…
• inverter Information
The SNMP Card allows you to view the information and status of the inverters locally or remotely. An event log file
which contains all inverters -related events, such as power failures, shutdowns, power recoveries, etc. A data log file
which is collecting electrical parameters, inclusive of input voltage, output voltage, output frequency, temperature,etc…

SNMP Card uses the HTTP (Hypertext Transfer Protocol) to monitor the inverters. By this way, it can drive the inverters
become the standard inverters. By this way, it can drive the inverters become the standard network management
device. Hence the user can remotely control and get the condition of the inverters via general web
browser (such as Internet Explorer, Netscape Browser…etc) as easily as surfing a web site.
In addition, we provide the full-fledged OPTI-Solar Solar control-for-SNMP Card to satisfy the PV system management

ON-GRID INVERTER ACCESSORIES
Wireless Module
Features
• Quad-band 900/1800, 850/1900 MHz GSM/GPRS/EDGE
• GPRS Class 12
• Versatile operating modes, including Real COM, RFC2217, TCP Server, TCP Client, UDP,
• Ethernet Modem, and SMS Tunnel
• Port buffering function to prevent loss of serial data when communication is disrupted
• Port speeds of up to 921.6 Kbps
• Any Baud rate feature for easy configuration of custom baud rates
• Redundant DC power inputs
• LED indicators for status and signal level
• 2 digital inputs and 1 relay output
Description
The Module industrial RS-232 or RS-232/422/485 GSM/GPRS/EDGE IP modems are designed to transmit data and
short messages (SMS) over GSM/GPRS/EDGE cellular networks. The Real COM operation mode automatically
generates a virtual COM port to match serial ports supported by the module, allowing you to communicate with remote
serial devices. The module’s CPU comes pre-installed with the TCP/IP protocol suite to transmit data back and forth
between the serial device and cellular TCP/IP network. It also comes with a built-in relay output that can be configured
to indicate the priority of events when notifying or warning engineers in the field and the two digital inputs allow you to
connect basic I/O devices, such as sensors, to the cellular network. The module can be mounted on a DIN-rail, and the
12 to 48 VDC power input has 2 KV EFT/Surge protection to allow the use of different types of field power source. The
serial ports are also protected by 15 KV ESD line protection to keep your system safe from unexpected electrical
discharges.
Features
● Connect serial device to Wireless LAN network
● 802.11b Wireless LAN, compatible with 802.11g
● WEP support for 64-bit and 128-bit encryption
● Password authentication and IP filter
● 10/ 100M Ethernet for console
● 1 or 2 RS-232/ 422/ 485 ports, at up to 230.4 Kbps
● Versatile socket operation modes, including TCP Server, TCP Client, and UDP
● Easy-to –use Windows Utility for mass installation
● Supports Windows and Linux Real COM drivers
● LEDs for link power, and wireless signal strength
Description
Solar Wireless module Device Servers are the ideal choice for connecting your RS-232/ 422/485 serial devices – such as
PLCs, meters, and sensors-to an IP-based wireless LAN and Ethernet LAN. Access your software and serial devices from
anywhere over a wireless LAN or the Internet.
Communication mode
In the following example, solar wireless module devices establish an peer-to-peer relationship, which means that they communicate
with each other directly.
SMS Mode
A major benefit of GSM technology is that it supports short messages (SMS) for easy communication over the mobile
network. SMS Mode allows you to expand your applications and reduce cost. For example, SMS Mode can be used to
update the message on a highway display panel, place refill orders for vending machines, handle maintenance for
remote rental equipment, or even help create an SMS alarm by directly transforming text, binary, or Unicode data from
a legacy device to short messages. SMS Mode is particularly suitable for devices that communicate infrequently, or
lack access to the local network. SMS Mode converts ASCII, binary code, and UCS2 data to short messages transparently
(both back and forth). In addition, the caller ID (phone number) identification can be used to block messages sent
from uncertified users, broadcast messages, and unwanted SMS advertisements.
