SolarMax MaxWeb XPN Installation Instructions Manual page 8

Overview
The MaxWeb XPN has been developed for energy management by the SolarMax group.
As an intersection of the location-independent monitoring, it captures current measure-
ment values, yield data and events. As an energy management centre, it regulates the
energy flow and adjusts the energy demand to the availability. This allows for an intelli-
gent use of the resources.
Any obtained or delivered output is visualised and internal consumption as well as saved
current are represented in a graph. The software of the MaxWeb XPN is self-learning.
On the basis of the typical consumption and the weather forecast, the data logger will
determine the optimal time for storage of solar power, which increases efficiency and
maximises returns.
MaxWeb XPN Features
The MaxWeb XPN has the following features:
MaxWeb XPN is downward compatible as it is based on MaxWeb xp.
■ ■
MaxWeb XPN is suitable for MaxRemote, i.e. the network operator has the possibility
■ ■
to remotely reduce the effective power of his PV plant temporarily in order to prevent
an overload of the power grid.
MaxWeb XPN is equipped with integrated WLAN, an internal WLAN antenna is
■ ■
included within the scope of delivery.
MaxWeb XPN has a Modbus TCP interface for direct connection/control for direct
■ ■
sellers.
MaxWeb XPN has 8 digital inputs, 4 digital outputs, 4 analogue inputs and one RS485
■ ■
interface.
With the two S0 counter inputs of MaxWeb XPN, you can record the load profile and
■ ■
determine the energy flow for energy management.
MaxWeb XPN is located in a standard profile rail housing with a two-line LCD display
■ ■
on which important information can be displayed for a quick overview and requested
by using the navigation keys.
MaxWeb XPN is operated via an intuitive user guidance. This web interface can be
■ ■
called up and operated comfortably from a PC as well as from mobile devices (smart-
phone, tablet).
MaxWeb XPN has a device replacement function. In case the MaxWeb XPN needs to
■ ■
be replaced, the replacement device configures in a time-saving and nearly autono-
mous way to the last state of the replaced device without the need for a complete
reconfiguration.
MaxWeb XPN is an energy management centre which is used to manage the energy
■ ■
flow of a complex plant. Various systems, devices and battery systems can be con-
nected, monitored and controlled via the different interfaces (Ethernet, Modbus,
RS485, KNX, CAN-Bus, etc.).
