2.DESCRIPTION OF THE SYSTEM

The SUNSYS series covers a range of power from 33.3 to 100 kW and consists of 1, 2 or 3 modules of 33.3 kW each.

Each module converts the energy provided by the solar panels, using a Maximum Power Point Tracking (MPPT) algorithm to fully exploit the features of the photovoltaic cells.

The DC terminals of all modules can be connected to the same photovoltaic field (centralised modular inverter with single MPPT), or can have different photovoltaic fields (centralised multi-string inverter with separate MPPTs).

Load rate

In the case of the centralised modular inverter, the 33.3 kW modules run on Energy Saver mode.

This type of operation has two advantages:

• Longer equipment lifetime, as the individual modules are switched on and off at random and run for less time on average, instead

of all being switched on and off at the same time.

• Increased efficiency, as only the equipment actually required is activated and operates under optimal efficiency conditions (30-60%

of rated power).

In the case of centralised multi-string inverters, the MPPT algorithm of each module runs independently to maximise the power supplied by the photovoltaic panels.

The inverter is equipped with an isolation transformer as standard, and can therefore be used with all photovoltaic panel technology (crystalline, thin film, back contact etc.). For technology which requires one of the photovoltaic generator poles to be earthed, the special optional kit (GND) must be used.

2.2.1. Options

SUNSYS pro and SUNSYS station can be ordered together with the following options:

• Earthing: PV generator + or – pole earthed (GND)

• Permanent isolation controller (IMD)

• AC over-voltage dischargers (SPDO)

• DC over-voltage dischargers (SPDI)

• Cable fastening brackets

For detailed information regarding the options refer to the relevant documentation.

6. OPERATING MODES

6.1. ACTIVATING THE INVERTER FOR THE FIRST TIME

The first time the equipment is switched on the system displays the Activation page; a guided procedure follows on the screen. In particular, when scrolling the menu options it is possible choose the user interface language, set the system configuration and the country in which the equipment is installed.

System setup

In the system setup menu set the number of modules installed in the cabinet from 1 to 3 depending on the size of the machine (33 kW, 66 kW or 100 kW).

NOTE

All the modules inside the cabinet must be powered in order to successfully complete the configuration procedure. When following the guided procedure if more than one module is fitted the type of connection on the DC side is required for each. This can be:

• Stand-Alone if the module in question is connected individually to an array of photovoltaic panels (see figure 2.2-9 Centralised Multi-String Inverter);

• Modular if the module in question is connected in parallel with other modules to the same array of photovoltaic panels (see figure 2.2-8 Centralised Modular Inverter).

Confirm the settings.

Transformer configuration

When installing the 100 kW system (3 modules) make sure the type of transformer selected in the Transformer Type menu corresponds to the installed device. The default transformer type 'SOCOMEC (built-in)'; only select 'External' if the machine is not fitted with a SOCOMEC transformer.

Country Setting

Choosing the country is particularly important, as it leads to the automatic configuration of the inverter in compliance with the standards in force in that country.

All other parameters appearing in the 'initial startup' guided procedure menu will therefore be configured correctly and will not usually need to be changed, unless the local electricity supply company has specific requirements which need to be met.

NOTE

The country of installation cannot be changed after the first machine activation. If this becomes necessary, contact an authorised SOCOMEC service centre.

NOTE

The installer is responsible for carrying out the procedure in accordance with national standards.

9.1. REGULAR INSPECTION OF THE INVERTER

Carry out a visual and mechanical check every month, to guarantee continuous reliable operation:

• Check the transformer fans by activating them manually using the mimic panel command.

• Make sure the cables are well secured. Thermal stress means that the screws may loosen over time. Tighten the screws if necessary.

• Switch off the inverter (ch. 6).

• Check the connections, components and fuses, looking for any discolouration or damage. Discoloured components indicate damage caused by heat or corrosion and must be replaced.

• Check for excessive dust on the cards. If necessary, contact an authorised SOCOMEC service centre to request machine cleaning.

• Use the designated holes to inspect the connections using an infrared thermal camera.

MODE

9.2. PREVENTIVE INVERTER MAINTENANCE

We must specify that the inverter should undergo regular specialist maintenance (on an annual basis), in order to maintain optimum equipment efficiency while preventing system downtime and all associated damage and risks.

We recommend any preventive maintenance requirements which may be displayed automatically by the equipment via an alert/ warning message are observed at all times. All procedures carried out on the equipment must be only carried out by SOCOMEC UPS personnel or by authorised support personnel.

Maintenance involves thorough operational checks of the various electronic and mechanical parts and, if necessary, the replacement of parts subject to wear and tear. These parts typically include fans and capacitors.

Fans

The lifetime of the fans used to cool powered parts depends on the environmental and operating conditions (temperature, dust). The average life of these components is 10 years.

WARNING!

Fan replacement can only be carried out by qualified personnel. If the fans need to be changed, they should be replaced with a product which meets SOCOMEC specifications.

ENGLISH

Capacitors

Electrolytic capacitors and filter capacitors are fitted inside the appliance; the life of these components depends on the environmental and operating conditions, which is why we recommend they are replaced by authorised personnel as a preventive measure. The average life of these components is 10 years.

The effective condition of the components is verified during the preventive maintenance visit.

10. TROUBLESHOOTING

The alert messages which can appear on the display offer immediate diagnosis of any faults, malfunctions or breakdowns in the photovoltaic system. The following events are indicated:

• Warning: non-serious alert conditions which cause the inverter to stop but can be reset automatically

• Alerts: serious alert conditions which cause the inverter to stop and require a manual reset command from the operator to be reset.

Alerts and warnings are divided into two categories:

• System Alerts/Warnings: these affect the parts external to the UPS, such as the mains power network, the output line and the ambient temperature. Corrective actions can usually be activated by the user (system installer or operator)

• Inverter Alerts/Warnings: relate to the parts of the inverter. Corrective actions are generally activated by the Support Service.

10.1. SYSTEM WARNINGS

• W01: Ambient Over-temperature

The ambient temperature recorded by the inverter is over 45° (see values on mimic panel). Check the ventilation or air-conditioning system in the inverter room.

• W02: Ambient Temperature under the minimum threshold

The ambient temperature recorded by the inverter is under 15° (see value on mimic panel). Check the ventilation or air-conditioning system in the inverter room.

• W03: System efficiency not aligned

The power obtained from the inverter is too low in relation to the rated system power. Make sure the photovoltaic panels are connected properly.

• W04: Internal Over-temperature

• W66: Internal Over-temperature

The temperature of the inverter power structure is over 110° (see value on mimic panel). Check the ventilation or air-conditioning system in the inverter room.

• W05: Low Radiation

• W67: Low Radiation

The inverter is waiting for the incoming energy level to increase before attempting activation.

• W06: Continuous input voltage too low

The inverter is waiting for the incoming energy level to increase before attempting activation.

• W19: No inverter present

There has been no radiation for over 24 hours: this condition may be normal but is highlighted so that the necessary checks can be carried out.

• W20: High impedance to earth

If the isolation controller and resistance to earth recorded is too high this warning is generated: check the protective fuses and if the problem persists contact the support service.

• W69: AC input network outside tolerated range

• W70: AC input network outside frequency range

The input network is missing or insufficient (voltage and/or frequency values incorrect in reference to the information provided in the technical data table); if this is not due to a general network absence, check for any disconnection of protective devices upstream of the inverter. Check the applied voltage and frequency comply with the values set on the mimic panel.
