Connecting to the Electrometer

Installation

Solar Monitor can be connected to Green Bonus electro meter via any of three binary inputs DI. It reads the energy output of your PV plant.

The following picture shows how to connect to the electro meter with S0 (puls) output:

In order to get the right data, the right number of pulses per 1 kWh must be set up in the unit.

Default setting is 1000 pulses per 1 kWh. If your electro meter has different number of pulses, change the default setting value.

1. Direct measuring

In the electro meter's label or documentation find out how many pulses per 1 kWh your electro meter generates at the SO output. Fill in this value into relevant box in SM2-MU menu Inputs & Counters.

2. Indirect measuring

In the electro meter's label or documentation find out how many pulses per 1 kWh your electro meter generates at the SO output. Use this number in calculation, see example bellow.

Example: Electro meter's label states 10 000 impulses per 1 kWh.

Look at the indirect power measuring transformer (1 transformer connected to each phase) and find a ratio (e.g. 150A/5A). Use the result of this ratio (30 in this example) in the formula (10 000/30). Fill in the result into relevant box in SM2-MU menu Inputs & Counters.

In case you want the electro meter connected to the Solar Monitor and use pulse output for another device (e.g. Wattrouter) at the same time, follow instruction in the next picture:

Local Area Network (LAN)

In order to communicate with the user, Solar Monitor must be connected to ethernet (LAN). There is one port RJ-45 available, the same as in PC's. The unit is connected to the net in the same way as PC.

Connect the unit into LAN (to the switch or PC) with a straight or crossover UTP cable. UTP cables for connecting to LAN are available in PC shops.

Straight UTP cable = both ends are the same (T568A)
Crossover UTP cable = T568A + T568B

The device is connected to the net if a green LED light “LINK”at RJ45 terminal of SM2-RM switches on.

Digital Inputs and Outputs

Inputs

Solar Monitor has 3 digital inputs DI. It is easy to connect movement sensor, surge, optical barrier, door sensor and various other devices that use contact inputs to indicate its status. Any of the inputs DI1, DI2, DI3 can be used for measuring energy at the electrometer on condition that it has pulse output SO.

Pulse output S0 is a special measuring output where there the electrometer generates pulses by switching. Solar Monitor unit counts the pulses and converts the pulses to kWh in selected conversion coefficient.

Conversion coefficient differs according to the electrometer's type and in most cases it doesn't correspond with the number of LED diode pulses. It is very important to select the right coefficient for SO output. Most electrometers have 250/kwh number of pulses at the LED diode and 1000/kwh at the output SO. You will find out how to enter the right coefficient into Solar Monitor unit in chapter Inputs & Counters.

In order to use inputs you have to bring power signal DC- to the terminal DCOM . In order to switch on the input you have to bring power signal DC+ to appropriate terminal DI.

It is possible to connect more devices to a single contact loop and monitor the entire circuit as one name. But if one device changes contact status, you won't be able to identify which device has caused the alarm.

Outputs

You can choose one relay which is in SM2-MU. The relay can switch on the ventilation according to current ambiente temperature or it can control the boiler (must be connected via contactor) according to the current energy production etc.

Inputs & Counters

Submenu Inputs and Counters enables setting up inputs.

Default setting of the chart

Select input function
Solar Monitor has 3 inputs available. Each works as:

a) Input = binary input

This chart presents current input status. Set up allowed value for them.

Choose if you want to receive report (by email or SMS) when input changes status (on/off).

b) Counter = for reading pulses from the meter (electrometer, gasmeter, watermeter)

In the chart Inputs and Counters select function Counter for the particular input where meter is connected.

Meter can be connected to any of the 3 inputs. There can be up to 3 meters at each SM2-MU.

After you have chosen function Counter, its setup chart appears.

Enter its name (e.g. electrometer) and select its type.
Enter the correct number of pulses per 1 kWh (as specified in SO output at the counter).

In default setting there is 1000 pulses per 1 kWh. If your electrometer has a different number of pulses, you need to change this value in the chart.

Number of pulses per 1 kWh is normally between 250-1000 imp/1kWh. If your electrometer has two numbers of pulses, the right SO output number is usually the lower one.
Higher number says how many times light diode at the electrometer flashes.

Follow the instructions if you need to set up number of pulses other than 1000 per 1 kWh:

For direct measurement

Find out how many pulses per kWh does your electrometer generate at SO output. This information is available at the label or in its documentation. Enter this number into the box Pulses Count in SM2-MU.

For indirect measurement

Find out how many pulses per kWh does your electrometer generate at SO output. This information is available at the label or in its documentation. Use this number for the following calculation .

Example: Electrometer specification says there is 10 000 pulses per 1 kWh.

Check transformer of indirect power measurement which is connected to electrometer (each phase one transformer). You should find a ratio (e.g. 150A/5A). Calculate the ratio (150:5=30 in this example). Use the result number (30 in this case) in this formula 10 000/30. Enter this number into the box Pulse Count.

If you enter incorrect number of pulses, Solar Monitor will be unable to present correct information about the power production. If the counter does't read the pulses, please check electrometer's cables and connection polarity.

c) Input and Counter = reading out of devices detected at RS485, RS232, Ethernet + binary input is active as well at the same time

After you have chosen function Input and Counter, a chart of Counter setup appears.
If there is e.g. inverter production selected, there will be total sum of all detected inverters in Production summary.

In case you use this input as binary, set up its allowed value.

After each change in settings, don't forget to press button .

Production Overview

Overview

Overview gives you overall information about your PV plant.

This menu shows all important information about your PV plant. If there is an alarm status of any component (it doesn't work properly or exceeds limit values) it is highlighted in colours.

Orange colour appears immediately after exceeding the limits. With sensors that send notification (e-mail, SMS) or record alarms in history, this status is considered an alarm after the “sensor alarm delay” runs out. Red colour appears, notification to the user is sent and/or it is recorded in alarm history.

Relevant sensor setup, time delays before alarm announcement and ways of notification to the user to be found in chapter Sensors and alarms.

Produced Energy, Earnings

These boxes show today's and total production in kWh and today's and total revenue in Czech crowns. Revenue is calculated roughly: multiply number of kWh produced by current Green Bonus price (or obligatory purchase). You have to set up the prices in menu Billing/Price setting, see chapter Inputs & Counters.

Supply, Consumption

In order to show supply and consumption, a meter (e.g. GreenBonO) must be connected to Solar Monitor. Counting supply and consumption must be set up in the menu of Inputs and counters.

Sensors

This box shows all detected sensors and their current values. The values are updated every second. You can name sensors and set up limit values in menu System setting/Sensors and alarms, see chapter Sensors and alarms.

Inputs and Outputs

It shows current status of two binary inputs and one relay output in Solar Monitor unit. Each input has two possible states: Opened or Closed. You can use these inputs to connect any component with contact status signaling - e.g. surge, movement sensor, door sensor, optical barrier or security output.
Inputs are able to distinguish 100 millisecond.

You will find Description of input connection and their set up in chapter Digital inputs and outputs.

With SM2-AD module, SM2-DI module connected, it shows current status of inputs and outputs of these modules.

Information from devices

All connected and correctly set up inverters, MPPT trackers, batteries, meters are shown here, including their status, current regime, output and temperature. These values come straight from the inverters every second.

Some manufacturers don't give all parameters (e.g. temperature).

Extension Modules

Expansion modules installation

Expansion modules add functions to the basic Solar Monitor unit.
In case you install SM2-MU without any other modules, skip this stage.

Connect HBUS to SM2-MU. Then connect all modules to the SM2-MU as in the picture bellow.

These expansion modules can be connected to the Solar Monitor unit:

SM2 - AD
SM2 - BE
SM2 - DI
SM2 - GSM
SM2 - PC

In order to connect expansion module to the basic Solar Monitor unit you need to buy HBUS. But each expansion module has its own HBUS. In order to connect two expansion modules, you don't need an extra HBUS.

SM2-PC

PC module (Power Control) controls your PV plant's power production. PV plant automatically adjusts its production according to purchaser's (ČEZ, E.ON, etc.) requirements. PC module can control both active and reactive power production.

Power control signals wiring

Signal DC- has to be connected to ACOM and BCOM terminals in order to control the power. Signal DC+ has to be connected to the multiple terminal of power control source (net operator's device). Power control signals are connected to terminals A1-A5 to control active power in % and to terminals B1-B5 to control reactive power (cos φ). The following picture shows sample scheme of active power control wiring in 0 - 30 - 60 - 100%.

Start and configuration

As soon as the modules are connected and Solar Monitor unit is connected to the power supply, a green LED diode indicating status should glow. In case it doesn't glow, check if module is connected to SM2-MU. Open menu “System set up / Power control” in you browser. You have to set up inputs combinations and relevant power control values in % or cos φ here.

If you wish to use PC module for more Solar Monitor units, select option “Remote” in menu “Power control source” for each unit. Fill in the address of SM2-MU, where the power control module is connected. .

Start and Configuration

When the modules have been connected and Solar Monitor has been connected to the power supply, green LED diode Status must glow.

If the diode is not glowing, check connection of the module and SM2-MU.

Open menu “System Setup / Inputs and Counters” in your web browser.

Next >>

Analog Outputs Setup

In case you don't intend to control voltage at your SM2-AD module's analog output, go to Next >>

Open menu “System Setup / Outputs” in your web browser.

We set up analog output in the same way as digital outputs. Select the factor determining the output setup (e.g. temperature in the room with inverters, PV plant's production).

1st example: Regulation of Ventilation Revolving
Set up the temperature range corresponding to value 0 - 10 V at the output. The temperature is going to determine ventilation revolving.

I.e.:
y = the number of Volts in the range from 0 (V) to 10 (V) that output will deliver with a given temperature range
given temperature range: x1 = minimum (°C) to x2 = maximum (°C), e.g. 15 - 40 °C
x = current temperature in the room (°C), e.g. 28 °C

y = [10 / (x2 - x1)] * (x - x1)
y = [10 / (40 - 15)] * (28 - 15)
y = 5,2 V

2nd example: Charging Storage Battery
Set up PV plant's production range corresponding to the value 0 - 10 V at the output. This will determine charging the storage battery.

I.e.:
y = the number of Volts in the range from 0 (V) to 10 (V) that output will deliver with a given PV plant's production range
given PV plant's production range: x1 = minimum (W) to x2 = maximum (W), e.g. 2500 - 10000 W
x = current PV plant's production (W), e.g. 5200 W

y = [10 / (x2 - x1)] * (x - x1)
y = [10 / (10000 - 2500)] * (5200 - 2500)
y = 3,6 V

Simultaneous Connection of Multiple SM2-AD Modules

SM2-MU can operate up to 8 SM2-AD devices.

If there are two SM2-AD modules connected to one Solar Monitor unit, they must have two different addresses for communication with SM2-MU.

In order to do so, switch over yellow shifting switch. If there are more than two SM2-AD modules connected to SM2-MU, specify the number in your order. The shifting switch changes addresses 2-3, 4-5, 6-7, 8-9.

<< Back

SM2-DI

DI module increases the number of unit's digital inputs significantly and enables connecting other devices.

Connecting digital inputs

Module SM2-DI has 10 digital inputs. Digital inputs DI can be connected in the same way as inputs to SM2-MU. You can easily connect movement sensor, surge, optical barrier, door sensor and other devices that use contact output to indicate its status.

There are two ways of wiring.

The first one requires connecting terminal DC- to SM2-MU with relevant terminal DCOM at the module SM2-DI. One terminal DCOM goes with inputs DI1–DI5 and the second terminal with inputs DI6–DI10. In order to start the input, signal DC+ from SM2-MU unit has to be connected to relevant terminal of SM2-DI terminal.

For the second type of wiring, where inputs of SM2-DI module use external power supply (see the following picture), voltage has to be in the range of 8-80 V.

Start and configuration

When you have connected the modules and Solar Monitor unit has been connected to the power supply, green LED diode indicating status should glow. If it doesn't glow, check the wiring of SM2-MU and the module.

Open menu “Settings / Inputs & Counters” in your browser.

Select limit values for relevant connected inputs.

It is possible to choose the type of message (e-mail, SMS) that informs the user of changes in input values.
