5.5.2 DC connections and DC isolating switch

Fig. 5.8: DC connections and DC isolating switch

The DC connections are used for connecting the PV module

string(s) to the solar power inverter.

The integrated DC isolating switch can separate the solar power

inverter from the DC voltage of the PV modules.

The maximum permissible input current is 29 A for each DC con-

nection.

Connection type: Multi-contact MC4 connector, paired plug (DC+)

and socket (DC–), 3 pairs.

5.5.3 AC connection

The AC connection is used for connecting the solar power inverter

to the grid.

The solar power inverter can be connected to a grid with 3 phases

and a grounded star point (L1, L2, L3, neutral conductor and pro-

tective ground conductor).

The grid must have one of the following grounding systems:

●TN-C

●TN-S

●TN-C-S

●TT

Connection type: Amphenol C16-3 AC, plug supplied in the scope

of delivery.

5.5.4 RS485 interface (EIA485)

The solar power inverter has two RS485 interfaces to which a PC

or a monitoring system can be connected.

The RS485 interfaces are internally wired 1:1. This means that both

RS485 interfaces can be used as an input or an output.

If multiple solar power inverters are connected together, each

solar power inverter must have a unique ID (identication number).

Monitoring systems require the ID to recognize each solar power

inverter in a PV system.

The last solar power inverter must have an RS485 termina-

tion resistor connected, which can be ordered from Delta (see

“16 Appendix”, p. 85).

The ID can be congured during commissioning (see “8 Commis-

sioning”, p. 30) and can be changed at any time during operation

(see “10.6 RS485 (EIA485) Settings”, p. 54).

Connection type: 2 x RJ45

5.5.5 USB interface

The USB interface is used for saving and loading data and reports.

Supported functions:

● Updating rmware

●Saving and loading settings

●Saving swap data

●Create reports

●Service

See “11 Saving and loading data and settings”, p. 65 for a

detailed description of the functions.

Connection type: USB A

5.6 Fan

The external fan is of sufcient dimensions to ensure sufcient

cooling of the solar power inverter within the operating temperature

range.

fan”, p. 81.

6. Operating Behavior

Operation and Installation Manual for SOL10.0-1TR3-E4 and SOL11.0-1TR3-E4

18

6. Operating Behavior

6.1 General Principle of Operation

The solar power inverter converts DC electricity into AC electricity,

which is then fed into the local power grid.

MPP Tracking

The solar power inverter has an MPP tracker. The MPP (Maximum

Power Point) tracker is an automatic function that continuously

searches for the operating point with the highest possible power.

On the normal setting, the MPP tracker searches the DC input volt-

age range near the current operating point. If a higher power point

is found, the solar power inverter sets this as the new operating

point.

The manual "Shadowing" function can be used to set the MPP

tracker to scan over a wider DC voltage range. This MPP tracking

function is especially useful when small shadows regularly pass

over the solar modules, e.g., from chimneys or trees. In order to

adapt the function to local conditions as precisely as possible, the

extended MPP tracking can be congured in three stages.

Electrical Isolation

The AC and DC sides of the solar power inverter are electrically

isolated by a high frequency transformer. This makes it impossible

for DC electricity to reach the AC side of the inverter.

Anti-Islanding

The integrated anti-islanding device switches off the solar power

inverter when the grid fails.

Temperature Control

The convection cooling system combined with the external fan

provides optimal heat dissipation.

An internal temperature controller reduces the output power at

ambient temperatures in the upper operating range. The higher the

operating temperature, the greater the power reduction. It is pos-

sible for the power reduction to be adjusted to 0 kW.

6.2 Impact of DC Input Voltage

The DC input voltage values mentioned in this section can be found

in Chapter “15 Technical data”, p. 83.

The maximum input voltage must never be exceeded. Measure

the input voltage and use an overvoltage protection device on the

DC side to prevent higher voltages from reaching the inverter. The

maximum open-circuit voltage occurs at the lowest assumed tem-

perature. More exact information on temperature dependency is

provided in the PV module data sheet.

The feed-in voltage range of the solar power inverter denes the

range of input voltages over which the solar power inverter will feed

electricity into the grid.

The MPP input voltage range of the solar power inverter denes

the range of input voltages over which the MPP tracker is activated.

6.3 Conguring Permanent Active and Reac-

tive Power Reduction

The settings for reduction of active power and/or reactive power

can be congured during initial commissioning. After completion of

initial commissioning the values can only be changed using a PIN.

6.4 Functions Affecting Operating Behavior

The solar power inverter offers various functions for affecting oper-

ating behavior:

●Active Power Control

●Reactive Power Control

●Insulation and grounding monitoring

●Extended MPP tracking in the case of partial shadowing of the

PV modules

The availability of individual functions depends on the congured

grid.

A detailed description of the functions is provided in Chapter

“10 Settings”, p. 52.

6.5 Balancing Asymmetrical Grid Loads

The 3-phase solar power inverters have integrated grid load bal-

ancing. This ensures that the fed-in power is always distributed

equally across all phases.

6.6 Data Analysis and Communication

The solar power inverter has a comprehensive system for recording

operating behavior.

The log can be viewed directly on the display. It is also possible

to view the log on a computer using the communication interface

(RS485).

Connecting a SOLIVIA Gateway M1 G2 to the solar power inverter

allows this information to be accessed worldwide via the Internet.

All information can be saved to a USB drive to be used later.

The following information and data are logged:

Production Information

The most important production information is recorded in statistics

for day, week, month, year and total runtime. There are also special

statistics for the last seven days the solar power inverter was in

operation.

All production information is backed up to a separate hard drive

monthly.

Conguration Settings

The conguration settings of the solar power inverter can be

exchanged between solar power inverters of the same type by

using a USB drive.

This above all makes switching solar power inverters easier.

Warning and Error Messages

Every warning or error message is stored in the solar power

inverter with a time stamp. The messages are stored in the event

log or in the internal log, depending on the cause of the error.

The event log is primarily intended for the installer and should make

analyzing and resolving problems easier.

The internal log helps Delta Solar Support when analyzing more

difcult problems.

Reports

The reports combine the various information on production, events,

settings, parameter changes and errors.

During use in grids as per VDE AR N 4105 and BDEW, the ve last

failures are saved together with the settings.

DANGER

Risk of death by electrocution

Potentially fatal voltage is applied to the solar

power inverter during operation. This potentially

fatal voltage is still present for ve minutes after

all power sources have been disconnected.

►Never open the solar power inverter.

►Always disconnect the solar power inverter

from power before installation, open the DC

isolating switch and make sure neither can

be accidentally reconnected.

► Wait at least ve minutes until the capacitors

have discharged.

NOTE

Read this Chapter before you start installation.
