2 Basic safety instructions

Installation and Operating Manual for RPI M15A M20A Solar Inverter V1.0 2016-03-18

2. Basic safety instructions

● In order to meet the safety requirements of IEC 62109-5.3.3 and to avoid personal injury and material damage, the in-

verter must be installed and operated in accordance with the safety instructions and work instructions in this manual. Delta Energy Systems is not liable for damage arising from noncompliance with the safety instructions and work instructions in this manual.

● The inverter may only be installed and commissioned by

tters who are trained and approved in the installation and

commissioning of grid-connected solar inverters.

● All repairs to the inverter must be carried out by Delta Energy Systems. Otherwise the guarantee will be void.

● Warning notices and warning symbols that have been at- tached to the inverter by Delta Energy Systems must not be removed.

● The inverter has a high leakage current. The grounding cable must be connected before putting the inverter into operation.

● Do not disconnect any cables when the inverter is under load, as there is a risk of arcing.

● To prevent damage caused by lightning strikes, observe the regulations that are applicable in your country.

● The surface of the inverter can become very hot in operation. Do not touch any part of the inverter except for the display unless you are wearing safety gloves.

● The inverter is very heavy. The inverter must be lifted and carried by at least two people.

● Only SELV-compliant (EN 60950) devices may be connected to the RS485 ports.

● To ensure protection class IP65, all connections must be adequately sealed. Unused connectors must be sealed with cover caps.

DANGER

Electric shock

During operation there is a potentially lethal voltage present inside the inverter. Even after the inverter has been disconnected from all power sources, this voltage is present in the inverter for up to a further 80 seconds. Therefore always perform the following work steps before working on the inverter

1. Turn the DC disconnector to the OFF posi-

tion.

2. Disconnect the inverter from all AC and DC

sources and make sure that none of the connections can be inadvertently re-established.

3. Wait at least 80 seconds to allow the internal

capacitors to discharge.

DANGER

Electric shock

There is a potentially lethal voltage present on the DC terminals of the inverter. The solar modules start to produce current as soon as light falls on them. This occurs even if the light is not falling directly on the solar modules.

► Never disconnect the inverter from the solar

modules when it is under load.

► Turn the DC disconnector to the OFF posi-

tion.

► Disconnect the connection to the grid so that

the inverter cannot supply any energy to it.

► Disconnect the inverter from all AC and DC

sources. Make sure that none of the connections can be inadvertently re-established.

► Protect the DC cables from being inadvert-

ently touched.

5 Operating behaviour

5. Operating behaviour

5.1 General mode of operation

The inverter converts the direct current generated by the solar modules into alternating current which is then fed into the public grid.

5.2 MPP tracking

MPP tracking is an automatic function which continuously ensures that the inverter is always operating in the maximum output range possible under the current ambient conditions. The DC input voltage is used as the reference for this.

The inverter has 2 MPP trackers, one for each of DC1 and DC2. The solar modules that are connected to the two DC inputs do not need to have the same output. Within certain limits, module strings with differing outputs can be connected (see “14. Technical data” page 162).

5.3 Anti-islanding device

In the event of a grid failure, the integrated anti-islanding device shuts the inverter down.

5.4 Temperature control

The specic values for the technical parameters described in

this section can be found in the chapter “14. Technical data” page 162.

The inverter has two operating temperature ranges that are important for its operating behaviour.

● Operating temperature range

● Operating temperature range without limiting

The operating temperature range is greater than the operating temperature range without limiting.

If the ambient temperature lies within the operating temperature range without limiting, the inverter works at the maximum possible output power. If the ambient temperature is higher, but still within the operating temperature range, the output power will be continually reduced with rising ambient temperature. If the ambient temperature rises above the operating temperature range, the AC output will be switched off and the inverter will no longer feed energy into the public grid.

The inverter is cooled by means of fans.

5.5 Inuence of DC input voltage

The specic values for the technical parameters described in

this section can be found in the chapter “14. Technical data” page 162.

The maximum DC input voltage must never be exceeded. Measure the DC input voltage and use an overvoltage protector on the DC side to prevent higher DC input voltages. The maximum open circuit voltage occurs at the lowest ambient temperatures that can be assumed.

The DC input voltage range is used to dene the DC input voltages for which the inverter will supply power to the public grid.

The MPP input voltage range is used to dene the DC input voltages for which the MPP trackers are activated.

The MPP input voltage range at full power is used to dene the DC input voltages for which the inverter can deliver the maximum output power. However the actual output power still depends on other conditions such as, for example, the ambient temperature.

5.6 Functions for inuencing the operating behaviour

The inverter provides various functions which can be used to

inuence the operating behaviour.

● Active power control

● Reactive power control

● Insulation and grounding monitoring

A detailed description of these functions can be found in the chapter “9. Settings” page 72.

5.7 Power grid imbalance compensation

The inverter has an integrated power grid imbalance compensator. This ensures that the supplied power is always distributed evenly across all the phases.

6. Planning the installation

This chapter is intended only as an aid to planning the installation work. The implementation

of the installation work and the associated dangers are described in the chapter “Installation”.

6.1 Installation location

Fig. 6.1: Installation location – condition of the wall

► The inverter is very heavy. The wall must be able to bear the

heavy weight of the inverter.

► Always use the mounting plate that is supplied with the

inverter.

► Use mounting materials (wall plugs, screws, etc.) that are

suitable for the wall or the mounting system as well as the heavy weight of the inverter.

► To prevent malfunctions, mount the inverter on a vibration-

free wall.

► When the inverter is used in residential areas or in buildings

with animals, possible noise emissions may cause a disturbance. Therefore take care when choosing the mounting location.

► Mount the inverter on a re-resistant wall.

✔

✘ ✘

Fig. 6.2: Mounting location – installation height

► Mount the inverter so that the information on the display can

be read without difculty and the buttons can be operated.

6.2 Mounting position

Fig. 6.3: Mounting position

► Mount the inverter vertically.

6 Planning the installation

6.3 Outside installations

Fig. 6.4: Outside installations

► The inverter is classied IP65 and can be installed inside and

outside. Nevertheless, the inverter should be protected from direct solar irradiation, rain and snow by means of a roof. If, for example, the inverter becomes too hot as a result of solar irradiation, the output will be reduced. This is normal operating behaviour for the inverter and is necessary to protect the internal electronics.

6.4 Environmental conditions and air circulation

>30 cm >30 cm

>50 cm

>20 cm

>30 cm

Fig. 6.1: Mounting clearances and air circulation

► Ensure adequate air circulation. Warm air must be able

to escape upwards. Leave sufcient space around each

inverter.

► Do not install inverters directly one above another as this

might cause mutual heating.

► Take note of the operating temperature range without limit-

ing and the operating temperature range. If the operating temperature range without limiting is exceeded, the inverter limits the AC power that is fed into the grid. If the operating temperature range is exceeded, the inverter stops supplying

the grid. This is normal operating behaviour for the inverter and is necessary to protect the internal electronics.

► In areas with many trees or meadows, pollen can block the

air inlets and outlets and impede the air ow.

6.7 AC connection (grid)

► Always comply with the specic regulations that apply in your

country or region.

► Always comply with the specic regulations of your energy

provider.

► Install all the prescribed safety and protective devices (for

example, automatic circuit breakers and/or overvoltage protection devices).

► Protect the inverter with a suitable upstream contact breaker:

Model Upstream contact breaker

to the inverter

Fig. 6.10: Position of the upstream contact breaker

Residual current device

Because of its design, the inverter cannot feed any DC residual current into the grid. The inverter thus meets the requirements of DIN VDE 0100-712.

Possible fault events have been investigated by Delta in compliance with the currently applicable installation standards. The investigations have shown that no dangers arise if the inverter is operated in combination with an upstream residual current device (RCD), Type A. The use of a residual current device, Type B, is not necessary.

Minimum tripping current of a residual current device, Type A

≥100 mA

The tripping current required by the residual current device depends primarily on the quality of the solar modules, the size of the PV installation and the ambient conditions (e.g. humidity). However the tripping current must not be lower than

the specied minimum tripping current.

Integrated residual current monitoring unit

The integrated residual current monitoring unit (RCMU) is certi-

ed in accordance with VDE 0126 1-1/A1:2012-02 §6.6.2.

6.8 DC connection

NOTE

Incorrectly dimensioned solar installation.

An incorrectly dimensioned solar installation can cause damage to the inverter.

► When calculating the number of solar

modules, always take heed of the inverter’s

technical specications (input voltage range,

maximum current and maximum input power).

NOTE

Overheating of the DC terminals.

Exceeding the maximum current can cause over-

heating of the DC terminals and lead to a re.

► Always take into account the maximum cur-

rent through the DC terminals when planning the installation.

6.8.1 Symmetric and asymmetric conguration of the DC inputs

The inverter has an MPP tracker for each DC input (DC 1 and DC 2).

The two MPP trackers work independently of one another; the optimum operating point is thus set separately for DC 1 and DC 2 For this reason, the module strings on DC 1 and DC 2 can have different alignments or dimensioning. A classic application example is a building with a gable roof on which the roofs face east and west.

Variant 1: Symmetric conguration of the DC inputs

The total input power is always evenly distributed (50%/50%) between DC 1 and DC 2.

Variant 2: Asymmetric conguration of the DC inputs

The maximum permitted total input power can be distributed between DC 1 and DC 2 in the range 67%/33% to 33%/67%. Thus, for example, a distribution of 60%/40% or 45%/55% is possible.

The percentages always refer to the instantaneous value of the input power. Consequently for an east-west roof installation it is possible to install 67% of the maximum input power on both roofs. It is then possible to exploit the effect that the solar modules on the two roofs reach their maximum at different times of the day.

6.8.2 Separate and parallel connected DC inputs

The inverter can be used with separately or parallel connected DC inputs.

Separately connected DC inputs

DC wiring

PV array

Fig. 6.13: Separately connected DC inputs

In this case the module strings for DC 1 are connected separately from those for DC 2. MPP tracker 1 controls the module strings on DC 1 and MPP tracker 2 controls the module strings on DC 2.

This way, symmetrically and asymmetrically congured DC inputs

can be implemented.

This variant of the DC cabling cannot be used for solar modules that are grounded.

This way, only symmetrically congured DC inputs can be implemented.

This variant of the DC cabling is mandatory for solar modules that are grounded.

6.9 Connecting to a data logger

The inverter can be connected to a data logger via RS485, for example to monitor the PV installation or to change the settings on the inverter.

Several inverters can be connected in series to a data logger.

The following recommendations must be taken into consideration for a stable data link.

Connecting a single inverter to a data logger

► Switch on the RS485 termination resistor. ► Run the RS485 cable at a distance from the other cables to

prevent interference to the data link.

Connecting several inverters to a data logger

► Switch on the RS485 termination resistor on the last inverter

in the chain.

► If the data logger has no internal RS485 termination resis-

tor, then switch on the RS485 termination resistor on the rst

inverter in the chain as well.

► Switch off the RS485 termination resistor on all the other

inverters.

► A different inverter ID must be set on each inverter. Other-

wise the data logger will not be able to identify the individual

inverters. ► Set the same baud rate for RS485 on each inverter. ► Run the RS485 cable at a distance from the other cables to

prevent interference to the data link.

Requirements for the cables

● Twisted and shielded cable

● Cable diameter: 5 mm

● Wire cross-section: 1 mm

6.10 Dry contacts

An external audible or visual alarm device can be connected to the dry contacts on the inverter.

6.12 Using an external grid and system protection device

For PV installations larger than 30 kVA, the German standard VDE-AR-N 4105, Section 6.1 requires the use of an external grid and installation protection device with section switch.

Alternatively, VDE-AR-N 4105, Section 6.4.1 allows the use of an inverter with an internal section switch if the switch disconnects the inverter from the grid in less than 100 ms.

This inverter meets the requirements of VDE-AR-N 4105, Section

6.4.1 if the following rmware is installed: DSP ≥ 2.20 / COMM

≥ 2.32. In this case, no external grid and installation protection

device is needed.
