3 Description

3�1 Function

Fig. 1: MaxWeb XPN

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 ow 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 efciency 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 prole and

determine the energy ow for energy management.

 MaxWeb XPN is located in a standard prole 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 congures in a time-saving and nearly autono-

mous way to the last state of the replaced device without the need for a complete

reconguration.

 MaxWeb XPN is an energy management centre which is used to manage the energy

ow 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.).

 MaxWeb XPN has interfaces which can receive or implement control commands from

external devices or instances.

 Using MaxWeb XPN, the demand for energy can be intelligently adapted to the avail-

ability. In this way, the available resources can be used intelligently.

Optional Modules for MaxWeb XPN

The basic components of the MaxWeb XPN can be extended with optional modules by the

internal CAN bus. The following optional modules can be added.

 MaxModul KNX – module for implementation into the existing home automation to

increase the proportion of own consumption

 User-specic modules – due to the modular design, it is possible to add custom-

er-specic developments in line with the demands of the customers.
