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 measurement 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 intelligent 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 WL AN 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 (smartphone, 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 autonomous 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 connected, 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.

8 Connection of external sensors

and alarm systems

The expansion port is a multi-function interface for connecting external sensors and alarm systems.

ATTENTION! Risk of damage to the device!

The interface carries active signals. Use caution during wiring and observe the specied limit values! SolarMax Produktions GmbH is unable to accept liability for defects or malfunctions of the MaxWeb XPN or connected devices resulting from improper wiring, the failure to observe limit values or the use of devices not approved.

8�1 Connection options

The expansion port has the following connection options:

 Analogue input for an irradiance sensor with 4…20 mA current loop  Analogue input for a temperature sensor with 4…20 mA current loop  Two inputs for switching contacts of external alarm sensors  Four potential-free status signalling contacts, e.g. for reporting malfunctions to a

higher-level operations control system or a visual display

 Six inputs for connecting a radio ripple control receiver (option MaxRemote)  S0 interface for energy meters

8�2 Irradiance and temperature sensor

Please note the following when connecting sensors for irradiance and / or temperature measurement to the expansion port:

 The distance between the sensor and the MaxWeb XPN should not exceed 50 m. For

larger distances, the auxiliary MaxMeteo module is required.

 The sensors can be supplied via the integrated 15 VDC / 0.5 A power supply at the

expansion port, if required.

 The precision of the measuring inputs is approx. + / – 5 % of the full-scale volume

(measured at 20 mA). Add up the measurement errors of the sensor in order to determine the overall accuracy.

 Only sensors with a 4 … 20 mA linear measuring signal are suitable for the meas-

uring inputs (e.g. irradiance 4 mA = 0 W / m2 20 mA = 1200 W / m

8�3 Conguration

The expansion port can be congured via the web interface of the MaxWeb Portal:

1. Log in to the MaxWeb XPN (see Section 6.3).

2. Open the “Devices > External devices” menu.

3. Activate the connected sensors, enter the data of the sensors and conrm with “OK”. For a detailed description, see Section 7.2.5.

8�4 Inputs for external alarm sensors

Connect switching contacts as external alarm sensors to the terminals IA and IB of the expansion port on the back of the MaxWeb XPN. The alarm sensors can be used for monitoring the function of a fan or an AC isolating switch, for example.

An activated switching contact that is closed continuously during the delay time will trigger an alarm. The alarm is congured as shown in “Alarms > Settings” (see Section 7.2.4). Alarm signals are transferred as “Error” or “Failure”.

Note

The external alarm inputs are unsuitable for personal protection or safety-relevant applications. SolarMax Produktions GmbH cannot accept liability for missing, late or incorrectly transferred alarm signals
