Please observe the following items, if you are using this mode of operation:
 MaxWeb xp does not allow for simultaneous connection of Ethernet and RS485
connections.
 You must congure the gateway inverters for the Ethernet connection. You can nd
information on the aforementioned in the device documentations.
 The TCP port must be identical for all gateway inverters.
 Each device within the MaxComm network must be equipped with an unambiguous
device address (the gateway inverters as well).
 The MaxWeb xp connection option must be set to the Ethernet interface.
 The automatic DHCP network connection is not supported by MaxWeb xp. For this
reason, the devices in the MaxComm network need a static IP address.
 Depending on the devices used and the design of the MaxComm network, additional
network infeeds are required.

12
Note
Detailed information on the design of a MaxComm communication network
can be found in the technical details on MaxComm. This document can be
downloaded from our website (www.solarmax.com; area downloads/data
communication).
5�5 Power supply
The power supply to the data logger is supplied by the plug-in mains unit (included in the
delivery package).
WARNING!
Risk of re when unsuitable mains units are used!
 For the power supply, you must use the plug-in mains unit included in the
delivery package.
Note
 The power supply should be independent of the inverter AC feed cable. If
this is not the case, the MaxWeb xp will be disconnected from the power
supply when the inverters disconnect from the mains.
 Use an uninterruptible 230 VAC power supply for the plug-in mains unit.
Any interruption in the mains power supply can lead to total failure of the
MaxWeb xp. In that case, the warranty becomes void and users cannot
make any claims under guarantee.
5�6 Changes in the MaxComm network
If you change the MaxComm network, e.g. by adding or replacing devices, you must rst
update the recorded data on the MaxWeb Portal.
ATTENTION!
Possible data loss!
 The data logger is reset every time a device search is carried out. Update
the recorded data on the MaxWeb Portal before starting a device search.

6 Conguration of MaxWeb xp
6�1 Switching on and off
Insert the round plug connector of the plug-in mains unit into the “+15 VDC” socket of the
MaxWeb xp. Then connect the plug-in mains unit to the power supply.
As soon as the power supply is connected, MaxWeb xp starts and the status LED comes
on. After approx. 30 seconds the device is accessible via the web browser.
Always switch MaxWeb xp off via the -button! Press and hold the key until the status
LED goes out and the device switches to standby mode. The power supply can now be
removed if required.
In order to start the device from standby mode, press and hold the -button until the
status LED comes on. A restart from standby mode is possible only after 30 seconds.
6�2 General
6�2�1 Connection cable
 For a connection to the LAN, the DSL router or the hub/switch use the grey cable.
 For a direct connection to the Ethernet interface of your PC use the red (crossover)
cable.
6�2�2 IP Address
 MaxWeb xp requires a static IP address in your network. The automatic IP address
assignment using DHCP is not supported by MaxWeb xp.
 The prexed IP address of MaxWeb xp is 192.168.1.234. If the prexed address of
MaxWeb xp is outside the address range (subnetwork mask) of your network or this
address has already been assign to another device, you must temporarily modify the
network conguration of your PC (see Section 6.2.3) and change the default setting
of MaxWeb xp. Otherwise you can create a connection to MaxWeb xp without any
further settings.

14
6�2�3 Modifying your network settings
Note
Check the correctness of your entries. If the entries are faulty, there is a likeli-
hood that MaxWeb xp will no longer be accessible via the Ethernet interface
after a reboot. Just in case, write down the values you have set before you
reboot MaxWeb xp.
1. Connect MaxWeb xp directly to the Ethernet interface of your PC using the red cross-
over cable.
2. From Windows XP open the menu Control panel > Settings > Network Connections
> LAN connection.
3. Select “Internet protocol TCP/IP” and click on “Properties”.

6�4 MaxWeb xp GPRS
6�4�1 Recommendations for the SIM card
To use MaxWeb xp via GPRS you need a SIM card with GPRS data service. The services
and tariffs offered by different providers vary widely. For this reason only general instruc-
tions can be given at this point.
 Required services: E-Mail, VPN, and DNS
 The following ports must be activated: 25, 53, and 9300
 Required protocol: TCP/UDP
 Do not use pre-paid cards.
 Select a provider offering good network quality at the selected location so that expen-
sive roaming fees can be avoided.
 MaxWeb xp GPRS is continuously connected to the Internet. Therefore please make
sure you select a card contract that is based on data volume rather than time. Other-
wise you may incur high charges.
 For smaller PV systems and daily data transfer the contract should allow for a min-
imum data volume of 300 MB per month. Select a larger data volume if you wish to
record a large quantity of data, access the installation regularly online, or transfer
data at short intervals.
Note
Data volumes quickly exceed 300 MB if MaxWeb xp must interrupt and re-
establish the VPN connection several times a day. This can happen if the
signal is too weak (see Section 6.4.2) or if other nearby GPRS devices compro-
mise the bandwidth. In situations like these you should conclude a payment
card agreement with a larger data volume.

16
 Flat-rate tariffs are usually cheaper than paying for the actually transferred data.
 On a pay-as-you-go contract without lump-sum tariff you should negotiate an upper
volume or fee limit with your supplier.
 Please note that certain contracts are based on block rounding for the transferred
data. Select a contract with daily or session-based block rounding. Hourly block
rounding or block rounding with large data blocks (>100 kB per day) is not
advisable.
6�4�2 Installation instructions for the MaxWeb xp GPRS
 The magnetic-base aerial provided is designed for application in dry rooms. It must
not be placed in metal cabinets, behind thick concrete walls, in basements or other
