1. Data Monitoring System Overview
The SolrenViewTM data monitor acts as the go-between the SolrenViewTM server and the
system site, thereby enabling web-view of data collected with the use of a browser (ie
Internet Explorer) to access the SolrenViewTM web server (http://www.solrenview.com/).
For revenue-grade monitoring, the monitor is connected to the pulse output of a KYZ meter
(please see Quick Installation Guide). It keeps count of the meter-triggered pulses, which can
then be multiplied by a meter-specific pulse ratio to get the cumulative kWh value.
For inverter-direct monitoring, the monitor is directly connected to the RS485 line of one
inverter (refer to Quick Installation Guide). Additional inverters (up to 16 total, inverter-toinverter) can be connected to the line with ‘daisy-chain’ cables.
In the example below, inverter PV#1 is directly connected to the monitor, while subsequent
inverters (PV#2 onwards) are connected in series to each other.
360 Merrimack Street, Bldg. 9, Lawrence, MA 01843, USA 978.683.9700 f:978.683.9702
www.solren.com
For residential inverters, a 6-foot inverter-to-monitor cable will be provided, as well as the
inverter-to-inverter ‘daisy chain’ jumper cable to link two neighboring inverters together.
For commercial inverters a twisted unshielded conductor pair of a Cat 5 cable can be used
for both inverter-to-monitor and inverter-to-inverter links.
The data monitor collects real-time data samples from inverters and pulse meters connected
at a 1-minute interval. The data is then sent over the Internet to the SolrenViewTM server as
soon as a connection can be established. Data samples received by the server are stored
and retrieved by the web server whenever a user queries the information with a browser (see
Viewing Web-Enabled Data).
2. System Requirements
For remote monitoring to be possible, the system must have a reliable Internet connection
via an Ethernet port. This usually requires the service of an ISP (Internet Service Provider).
Please inquire about ISP services available in your neighborhood if you do not have one
already (not included in the SolrenViewTM package).
The data monitor requires a physical connection via a Category 5 cable to the LAN (Local
Area Network). A common setup is a router/switch to the Internet connection, and a Cat 5
connecting the monitor to one of the router/switch’s ports.
Example: Simple LAN setup
Other remaining requirements include:
- A working Photovoltaic system (inquire installers for setup)
- Filled-out site survey (See The SolrenViewTM Site Survey)
360 Merrimack Street, Bldg. 9, Lawrence, MA 01843, USA 978.683.9700 f:978.683.9702
www.solren.com
- Purchase of Revenue-Grade Monitoring and/or Inverter-Direct monitoring packages from
Solectria Renewables. For Inverter-Direct, currently supported inverters include Solectria PVI
1800-2500, PVI 3000-5300, and PVI 13-95 kW.
- When using a non-outdoor-rated data monitor, it must be protected within an encasement
(ie indoor or shelter).
Wire/Cable Lengths
The total wiring distance between two final endpoints of a network must not exceed 100
meters (328 ft). This rule applies to both the Ethernet (wire length from data monitor to
router/switch/modem) and RS485 (wire length from data monitor to the last inverter of a
daisy-chain) networks.
The wires from the KYZ meter pulse outputs to the data monitor must not exceed 100 ft.

3. The SolrenViewTM Site Survey
In order to have enough information to customize a web site and enable data monitoring, the
site survey must be filled and turned in before the data monitor is shipped out. Below are
fields expected on the survey, please fill it out to the best of your knowledge. Form may be
submitted either through email or fax (see Contact Information). The site survey may
alternately be downloaded here: SolrenView Site Survey
**Notes: Starting October 2008 the SolrenView-specific fields will be included in the Inverter PO
checklists. Customers who fill out the SolrenView section in the checklist will not be required to fill out a
separate site survey.

SolrenView LAN Configuration
DHCP mode may be selected to let the SolrenView data monitor automatically be assigned an IP
from the local network DHCP-enabled router. If Local Area Network is not DHCP-enabled, a static
local IP address must be specified in the survey. In most cases, DHCP mode is appropriate unless a
fixed IP is preferred.
Please consult with IT personnel. For more information see More about DHCP vs Fixed IP mode.

Power: Always on orange when power is applied.
Function: Heart Beat.
Plug provided power adapter to the wall socket, the
small flat connector end to the power supply on the
board (top right corner of diagram).
Enabling Inverter-Direct Monitoring
The slave addresses of the inverters must be unique within the RS485 network. No two
inverters connected can share the same address as this will result in address conflict for the
data monitor. Please refer to your specific inverter manual for instructions on how to set slave
addresses.
Each residential inverter direct monitoring system is provided with a 6-foot inverter-to-monitor
cable. On one end of the cable is a modular plug that plugs into the inverter serial port. The
other end of the cable will have two conductors, one labeled ‘A’, the other ‘B’. The ‘A’
conductor is to be inserted into RS485-A screw terminal on the monitor, while the ‘B’
conductor is to be inserted into RS485-B screw terminal.
For commercial inverter direct monitoring (PVI13kW and higher), the installer has to provide a
twisted pair of conductors (i.e. CAT5 cable) to be connected between screw terminal blocks
of the inverter(s) and the monitor. Test for conductivity between A terminals of the inverter(s)
and A terminal of the monitor, then test for conductivity between B terminals of the inverter(s)
and B terminal of the monitor, before turning on the inverter(s) or the monitor.
Proceed to Ethernet Connection if Revenue-Grade Monitoring isn’t needed.

www.solren.com
Enabling Revenue-Grade Monitoring
When using an ABB FM2S or GE kV2c meter, make sure the inverter is wired to the top lugs of the
meter base and the building/utility is wired to the bottom lugs of the meter base to enable correct
forward counting. Connect pulse output of KYZ meter to the monitor, pulse leads ‘K’, ‘Y’, ‘Z1’ to
terminal blocks marked ‘K’, ‘Y1’ and ‘Z1’, respectively. Extend pulse wires where needed.
Supported KYZ meters: ABB FM2S, GE kV2c
Proceed to Ethernet Connection when ready.
Ethernet Connection
Once the wires have been set correctly to the terminal blocks, connect the CAT 5 cable to the
Ethernet port of the SolrenViewTM data monitor. See Example LAN Diagram.
Apply the power supply to the SolrenViewTM data monitor to turn it on.
Once there is network activity, the LED near the Ethernet port on the data monitor will blink
green.
**Note: Blinking of the LEDs on the Ethernet port (green, orange) only indicates the existence of a
physical connection. This does not guarantee that a successful outbound network connection if the
logical IP configuration (DHCP or LAN gateway, etc) has not been configured properly. Please see
IP Configuration for more information and Quick Installation Guide for the LED indicators.

8.Appendices
Appendix A: IP Configuration/Troubleshooting of the SolrenView Data Monitor
Reconfiguring the IP settings of the data monitor is only necessary if the data monitor is
unable to connect to the SolrenView server, which can be verified by viewing the system’s
web status page, see Status Indications.
Other reasons may include switching IP mode (DHCP to static IP address mode and vice
versa), or any other necessary adjustments to the monitor’s network configuration.
In order to configure the monitor’s network settings, at the very least its IP address must be
determined in order to access its web interface for manual IP configuration.
Step 1) Find the LAN IP address of the SolrenView Data Monitor
Skip to Step 2 if the monitor’s IP address is already determined.
To find the IP address of a DHCP-enabled SolrenView Data Monitor:
-Access and view the DHCP-client list of your local DHCP server. If the DHCP server is your
router, open a web page to the router, ie http://192.168.1.1 to find the DHCP client list. Refer
to your network admin and/or router manual for help.
-Find the entry in the client list with the MAC address matching the number displayed on the
SolrenView box, with format 00:90:c2:XX-XX-XX.
Example serial number display
The IP address of the data monitor should be displayed in the client entry.
Example DHCP client list
360 Merrimack Street, Bldg. 9, Lawrence, MA 01843, USA 978.683.9700 f:978.683.9702
www.solren.com
Step 2) Configuring the data monitor’s IP settings
Using a computer connected to the same network the monitor is in, open up a browser with
the monitor’s determined IP address using Step 1. For example: http://192.168.1.100.
If the page does not display, please call 978-683-9700 as older software versions may not
support this.
Once the main page displays, navigate to ‘Settings’. The IP configurations can now be
altered. To disable DHCP, deselect the DHCP box, and enter the intended fixed IP and
router/gateway settings.
Submit the page or press enter, the data monitor will reboot if DHCP mode is changed.
Verify that the new settings have been successfully configured.
For further troubleshooting refer to the following sections below.
When DHCP does not appear to be working:
DHCP configuration on the data monitor is done at startup, so the physical LAN connection
must be present during this time. Make sure the Ethernet cable is plugged in before powering
up the monitor.
To set the IP address of a DHCP-configured data monitor when DHCP is not supported
on the LAN:
If available, use a DHCP-enabled router or temporarily enable DHCP on an existing router to
find the IP address of the data monitor following the steps described in Step 1. Then set the
monitor to a fixed IP as described in Step 2, after which the monitor will become compatible
with a non-DHCP network.
DHCP-configured units shipped after December 2008 without a specified gateway IP will
fallback to the static IP of 192.168.1.11 (subnet mask of 255.255.255.0) in the event that
DHCP fails during startup. (For units which have been provide with a specific gateway/router, the
fallback IP will be the 11th address within the subnet of the provided gateway (ie If router/gateway field
is configured as 192.168.5.1, fallback will be configured to 192.168.5.11.) Use a switch, hub, router,
and/or crossover cable to connect to this IP address in order to reconfigure its IP settings as
described in Step 2. This fallback can be verified in the status box displayed under the
‘Settings’ page.
In the example below, the monitor fell back to 192.168.1.11 when DHCP failed during startup.
360 Merrimack Street, Bldg. 9, Lawrence, MA 01843, USA 978.683.9700 f:978.683.9702
www.solren.com
Setting the Data Monitor’s Router/Gateway Field:
Starting December 2008 DHCP-configured units that have not been specifically given the
router/gateway IP will have router IP field preset to 0.0.0.0. When this value is entered for
DHCP-enabled units, the data monitor uses ARP to automatically search for an existing
router/gateway.
In the example below, even though the router/gateway setting field was configured as 0.0.0.0,
the data monitor was able to detect the existing router (192.168.1.1) and automatically
configured the detected router IP as its gateway.
Auto router detection will only work if the data monitor is in DHCP mode. In static IP mode,
the router/gateway field of the data monitor (displayed above) must be set to the correct
gateway address.
**Note/Caution:
0.0.0.0 is not a valid IP address. Entering this in the router/gateway field will only trigger auto router
detection in units shipped after December 1st 2008. For older units, configuring the router/gateway field
to an invalid address will disable the data monitor’s connection to the SolrenView server.
It is not recommended to alter the router/gateway field to an invalid address once the gateway/router IP
is known and configured properly.

Appendix B: More about DHCP vs Fixed IP mode
Background: In every IP network, each device (computer, printer, router) must have a unique
IP address within the particular domain (ie Local Area Network, Internet).
In most simple Local Area Network setups, a router acts as the Internet gateway for a LAN.
When DHCP is enabled on the LAN, a DHCP server handles requests from DHCP clients
and automatically assigns an IP address to the device. This is especially useful as new
network devices can be easily added to the network.
In regards to SolrenView, the data monitor must be configured to either a fixed IP address, or
as a DHCP client.
If the data monitor is configured as a DHCP-client:
After bootup it broadcasts a DHCP request to the LAN, and only after a successful exchange
of messages with the DHCP server it is assigned an internal address within the network. If
the network is NOT DHCP-enabled, the monitor will not be assigned an IP, unless a fallback
IP has been configured. To reconfigure the data monitor’s IP settings, see IP Configuration
If the data monitor is configured to a static IP address:
The address specified in the site survey will be the only address the data monitor binds to. If
the subnet of the address does not match the LAN’s it may not be reachable.
Note: The default gateway/router IP must be specified along with the fixed IP when static IP mode is
selected in the site survey. The address specified must not be an occupied IP address in the LAN.
To determine whether a network is DHCP-enabled:
Check/access the router’s configuration, please refer to your router’s manual. If this is not
possible, you can check the IP settings of a local computer within the same or intended
LAN.
Checking IP configurations of a local computer (Windows only)
Step 1) Open a command prompt, ie Start->Run, type ‘cmd’ and press enter.
360 Merrimack Street, Bldg. 9, Lawrence, MA 01843, USA 978.683.9700 f:978.683.9702
www.solren.com
Step 2) Under the command window, type in ‘ipconfig /all’. This will print out the IP
configuration of the local computer. If the entry for ‘Dhcp Enabled’ is ‘Yes’ then the LAN is
DHCP-enabled (see line circled in green below).
If DHCP support still cannot be determined, the following are very general guidelines for
determining DHCP functionality of a LAN in the event it cannot be verified with LAN router
settings or a network administrator.
-Residential homes and smaller companies/organizations without an IT department/network
administrator are typically DHCP-enabled. Disabling DHCP on a network necessitates
having to manually allocate an IP address each time a network device is added, therefore
there’s an increased likelihood that there is a network administrator overseeing the IP
assignments.
- Higher security networks (ie banks) or companies/organizations with a more extensive
network structure are more likely to disable DHCP to prevent unknown devices from
accessing its LAN resources.
