Connector Assignments and Wiring

6 Connector Assignments and Wiring

The following connecting cables, which may be needed for various purposes, are not included in the pack-

age content.

To connect a router, you need a network cable with the appropriate length. If you want to connect the

•

Solar-Log™ directly to your PC or laptop, you need to use a crossover cable.

Cable to connect the Solar-Log™ to an inverter.

•

Sets of prefabricated cables are available as accessories suitable for the inverter concerned. The

•

length of these cable sets is 3 m.

If you want to connect several inverters to Solar-Log™, you need suitable cables and connectors to

•

connect the inverters to each other.

When wiring with CAT cables, the twisted pair of wires should be used.

•

6.1 Notes on wiring the connections

The wiring of the inverters and accessories needs to be carried out with the greatest care and attention.

The most frequent source of errors when installing the Solar-Log™ is faulty wiring.

For this reason, we recommend:

Wiring with high quality cables

•

For example: LIYCY >=0.14mm

Refer to the manufacturer's specifications in regard to UV resistance and mounting type when wiring

•

in outside areas.

A larger cable diameter is recommended for longer distances.

•

Use ferrules with flexible wires

•

Twist the corresponding wire pairs and shielding

•

Wire from left-to-right.

•

Wire from light to dark.

•

or Cat 5/7 SSTP

Connecting the inverters

7 Connecting the inverters

As each inverter manufacturer uses different wiring connections and connectors, the corresponding data

cables must be adapted correctly.

See Chapter„Belegung und Verkabelung der Anschlüsse“ for terminal block connector wiring diagrams

•

for the connection to the Solar-Log™

Please refer to the Component Connection Manual when connecting inverters supported by the So-

•

lar-Log™. (Download from https://www.solar-log.com/en/support/downloads/manuals)

Note

Solare Datensysteme GmbH supplies suitable connection cables for most inverter manu-

facturers.

Always read the manufacturer-specific instructions for connecting the data cable. You will find these in-

structions in the manufacturer's documentation.

However, when assigning the inverter wiring on the Solar-Log™, follow the instructions in this manual, oth-

erwise the inverters will not be detected by Solar-Log™.

Danger

Risk of death by electric shock if inverters are opened.

Never open the inverter housing when the inverter is connected to power.

See the chapter "Switching inverters off."

Always read the installation and safety instructions given in the manual for the corre-

sponding inverter.

Connecting the inverters

7.1 Switch o the inverters and the Solar-Log™.

Switching inverters off

Before a making a cable connection between the Solar-Log™ and the connections inside the inverter and

before installing an interface card in the inverter, always turn off all of the inverters first.

To do this, read the manufacturer's documentation for the inverter, and proceed as follows:

Disconnect the AC side.

•

Disconnect the DC side.

•

Wait at least 5 minutes until the condensers in the inverters have discharged.

•

Turn the Solar-Log™ off.

Hold down reset button for 10 seconds and then release it as soon as the components LED turns ( )

•

Orange. The Solar-Log™ will shut down and can be disconnected from the power supply (see chapter

18.1.1 "Reset Button" for more information).

8 Connecting accessories

8.1 External power meter

External power meters can be connected to the Solar-Log™ via the RS-485 bus.

The energy recorded by these meters can be used for numerous applications:

Generator Mode:

•

This mode is used, for example, for inverters that are not directly supported by Solar-Log™.

Total yield meter:

•

This mode is used to record the energy production of several inverters.

Consumption meter:

•

This mode is used to measure power consumption and to make it possible to display this data.

Connecting accessories

Note

We recommend using the meters that we have tested and offer.

We cannot guarantee the functionality of other products.

Refer to the Meter Connection Manual for all of the supported meters and their wiring

diagram. Download it from our website:

https://www.solar-log.com/en/support/downloads/manuals

Connecting accessories

8.1.1 External power meters/accumulating meters

With multiple phase meters, a basic distinction is made between phase-exact and accumulating meters.

Accumulating meters provide the total values from all three phases. The meter calculates the total output

(also to and from the grid) of the individual phases and provides this total as a single value.

In the example:

Phase 1 supplies 3 kW via an inverter (single phase).

Phase 2 draws 2 kW (energy)

Phase 3 draws 1 kW (energy)

With an accumulating meter, this results in a total of 0 kW.

Examples of accumulating meters are the Janitza UMG 104/UMG 604 and the Solar-Log™ Pro380-Mod.

13.3.5 Generation Information on PAC Correction Factor

At photovoltaic plants, several measuring points and power generators (inverters) are combined with one

another. The Solar-Log™ evaluates this data and partially looks for any correlations.

For example, if the total amount of energy produced based on what the inverters display is compared with

the values from calibrated power meters, deviations of up to 8% can arise.

In practice, meters and inverters both can display too much or too little kWh.

To correct these inaccuracies in the medium term, the Solar-Log™ firmware uses a PAC correction factor.

Calculating the PAC correction factor

All yield data are always stored internally without any correction factor. This factor is applied only when

the data are displayed. The factor can therefore be adjusted at any time.

The formula for calculating the correction factor is as follows:

(Yield power meter / yield inverter) * 1000

If the inverter does not have a display, it is advisable to use the values which are recorded by the So-

lar-Log™ from a period over a week.

That is why it is recommended to leave the default PAC correction factor at 1000 initially.

The correction factor can be adjusted yearly after receiving the statement from the utility company.

Example calculation:

Inverter 1 Inverter 2 Calibrated power meter

Total energy Total energy Total energy

259.12 kWh 305.22 kWh 550.55 kWh

Total = 564.34 kWh Deviation= 13.79 kWh

By comparing the values, you see that the inverters are more likely to display too much output.

Pac Correction Factor

Calibrated power meter total energy Inverter total energy

550.5 kWh 564.34 kWh

Calculated PAC correction factor in the example:

(550.55 kWh/564.34 kWh)* 1000= 975.66

Rounded PAC correction factor = 976

Module Fields

Each connected MPP tracker is assigned to a module field. Module fields are subdivided according to the

type of the solar module, angles of inclination and alignment. If all modules within a system are of the same

type and have the same alignment, only one module field, e.g. "1", is defined. MPP trackers that are not

used must be switched off (switched to "0").

Additional module fields need to be defined for modules with different alignments and module types. Ide-

ally, each field should be made up of at least two individual MPP trackers, which monitor each other. The

module fields are used for performance monitoring.

Example module fields:

A plant with 23.6 kWp is divided into:

3 x SMA SB5000TL and

2 x SMA SB2500.

18 kWp is located on a barn roof with 30° inclination, 20° South-East deviation, and 5 kWp on an adjoining

garage roof, 32° inclination, 0° South deviation.

This results in two module fields according to the following table:

The advantage here, for example, is that when some inverters are performing below a 70% limit, the output

from other inverters can be adjusted above the 70% to balance the final output to 70%.

This function allows the maximum amount of grid feed-in power to be configured. The reduction level in

regard to the amount of connected generator power can be freely defined to a particular output level (W).

The amount of self-consumption is taken into account for this calculation. The Solar-Log™ only regulates

the inverters when the amount of feed-in power for the grid has reached the limit. If there is enough

self-consumption, the inverters continue to operate without any reductions.

Procedure:

Select Adjustable reduction with the calculation of self-consumption

•

Enter the Output (W) for the adjustable reduction.

•

Select the inverter(s) to control in the Interface assignments section.

•

SAVE the settings.

•

Configuration Menu

Note

13.4.10 Percentage of consumption for an adjustable reduction

This function allows the maximum amount of power generated by the inverter to be configured. The per-

centage configured (freely adjustable) results in a corresponding reduction in regard to the total consump-

tion at the inverter.

Example:

The total consumption of an installation is at 2000 W and the reduction of the inverters is configured to

90%, leaving 1800 W. 200 W has to be purchased from the grid to cover the total consumption.

Procedure:

Select the percentage of consumption for the adjustable reduction.

•

Enter the percentage (%) for the adjustable reduction.

•

Select the inverter(s) to control in the Interface assignments section.

•

SAVE the settings.

•

The Solar-Log™ needs to be linked to a consumption meter to implement this function.

The column

point. The consumption values are displayed in all of the columns, but only the plant total is taken into

account.

Total always corresponds to the plant total and reflects the value from the grid connection

Note!

The values from the individual inverters are calculated per bus and for the entire

plant.

Generator power (kW):

The generator power corresponds to the module output of the inverter that is connected to this data bus.

This value results from the total of the partial outputs entered in the field generator power under config-

uration | Devices | Configuration. This kW values is used when calculating the output reduction (e.g.: the

70% reduction).

Maximum AC power (kW):

The maximum AC power of the inverter(s) depends on the device. Refer to the inverter specifications for

this value and configure it in the field Maximum AC power under configuration | Devices | Configuration.

Allowed power (kW):

This kW value is the maximum amount of power that is allowed at the grid connection point. The value is

calculated based on the generator output and the current power output.

Consumption (kW):

This value is calculated from the consumption meters and refers to the entire plant. The values displayed

in the respective bus column only refer to the plant total and are not taken into account in the correspond-

ing columns. The consumption value is normally subtracted from the allowed power from the entire plant.

Control value power (kW):

This value is calculated by the Solar-Log™ and is the maximum current power output from the inverters. It

is used for the current target power output.

Note!

Due to technical reasons, the calculation from the Solar-Log™ is subject to a round-

ing factor. This may lead to deviations in the data recording.

Diagnostics Menu

Current power output (kW):

The value refers to the current output generated by the inverter per interface (column) and for the entire

plant.

Control value power (% AC):

The Solar-Log™ calculates the control value power (kW) as a percentage of the maximum AC power and

relays this to the inverters.

Current power output (AC%):

The value indicates the total output generated as a percentage of the maximum AC power for the inverter

or all of the inverters on a bus.

Feed-in power (% DC):

This value is the current amount of feed-in power as a percentage of the generated output.

14.2.2 Explanation of the Symbols in the Feed-in power (% DC) column:

The feed-in power value is in the target power range with a tolerance of -2% to +1%.

The feed-in power value is below the target value allowed. Generally, this means that the out-

put allowed at the grid connection point is not being achieved due to low irradiation or high

self-consumption.

This means that the value is above the target value allowed.

If the red triangle is only displayed at a bus and entire plant has a green symbol, this means

that only this bus is over the target value allowed. However, the plant totals do not go over the

target value because of self-consumption.
