2.2 Function description

DC power generated by PV array is filtered through Input Board before entering into Power Board. Input Board also offer functions such as insulation impedance detection and input DC voltage / current detection. DC power is converted to AC power by Power Board. AC power is filtered through Output Board then AC power is fed into the grid. Output Board also offer functions such as grid voltage / output current detection, GFCI and output isolation relay. Control Board provides the auxiliary power, controls the operation state of inverter and shows the operation status by Display Board. Display Board displays fault code when inverter is in abnormal operation conditions. At the same time, Control Board can trigger the relay so as to protect the internal components.

Operating Principle

The DC switch disconnects internal circuits from the DC input to facilitate maintenance;

DC SPD (category III, category II is added to S4 & S5) provides the discharge loop for the overvoltage power on the DC side to protect the Sunny Horse Series internal circuits from DC overvoltage;

The input and output electromagnetic interference (EMI) filters filter out the EMI inside the Sunny Horse Series to ensure that the Sunny Horse Series meets electromagnetic compatibility requirements;

The Input Board detects the insulation impedance of the PV array and ensures the maximum output power of the PV system by measuring the voltages & currents of PV array and tracking the maximum power point (MPPT);

The DC-AC conversion circuit converts DC power into AC power and then the AC power is fed into the electric grid. The AC output power quality meets the requirements of the electric grid;

The output isolation relay isolates the inverter from the electric grid when the grid or the inverter is faulty.

The LC filter filters out the high-frequency components from the AC output of Sunny Horse Series to ensure that the AC output meets electric grid requirements;

AC SPD (category III, category II is added to S5) provides the discharge loop for the overvoltage power on the AC side to protect the Sunny Horse Series internal circuits from AC overvoltage;

The Communication Board enables the inverter to communicate via RS485, WIFI(optional), user can access all the operating data via the web browser(PC) and APP(ios & android).

A. Configurable relay

B.1 Remote switching on/off

Function module

The inverter has a configurable switching relay that can be used in various operating conditions set in the dedicated menu. A typical application example is the closing of the contact when an alarm occurs.

B. Energy management unit

2.3 Protection modules

This control can be used to switch the inverter on/off through an external (remote) control.

B.2 Feeding reactive power into the grid

The inverter is able to produce reactive power and can therefore feed it into the grid through the setting of the phase shift factor. Feed-in management can be controlled directly by the grid company through a dedicated RS485 serial interface.

B.3 Limiting the active power fed into the grid

The inverter, if enabled can limit the amount of active power fed into the grid by the inverter to the desired value (expressed as a percentage).

B.4 Self power reduction when grid over frequency

When the grid frequency is over limited value, inverter will reduce output power which do good to the grid stability.

B.5 Power reduction due to environmental conditions, input output voltage

The power reduction value and the inverter temperature at which it occurs depend on the ambient temperature and on many operating para-meters. Example: input voltage, grid voltage and power available from the photovoltaic field. The inverter can therefore reduce the power during certain periods of the day and according to the value of these parameters.

The inverter or a grid of inverters may be monitored remotely through an advanced communications system based on an RS485 serial interface, or remotely via the WIFI.

C. Data transmission

SD card is used for updating the firmware.

D. Software update

The inverter monitors the status of the surge arresters (both AC and DC) and generates a warning in the event of a fault (visible on the display).

E. Monitoring surge arresters (S4,S5 versions only)

A. Anti-islanding

In the event of a local grid outage by the electricity company, or when the equipment is switched off for maintenance operations, the inverter must be physically disconnected safely, to ensure protection of people working on the grid, all in accordance with the relevant national standards and laws. To prevent possible islanding, the inverter is equipped with an automatic protective disconnection system called “Anti-Islanding”.

B. RCMU

Sofar inverters are equipped with a redundancy on the reading of the ground leakage current sensitive to all components of both direct and alternating current. Measurement of the ground leakage current is carried out at the same time and independently by 2 different processors: it is sufficient for one of the two to detect an anomaly to trip the protection, with consequent separation from the grid and stopping of the conversion process.

C. Grid monitoring

Continuous monitoring of the grid voltage to ensure the voltage and frequency values stay within operating limits.

D. Inverter internal device protection

The inverter has all kinds of internal protection to protect the device inside when grid or input DC side have abnormal situation.

E. Ground fault protection

This inverter must be used with panels connected with “floating” connections, that is, with positive and negative terminals without ground connections. An advanced ground fault protection circuit continuously monitors the ground connection and disconnects the inverter when a ground fault is detected. The ground fault condition is indicated by a red LED on the front panel.

Relay Command Definition:

the relay switches whenever a connection to (and therefore a disconnection from) the grid occurs.

If the relay contractor is in normally open (close) mode, the contact will stay open (or closed) until the inverter is connected to the grid; once the inverter con-nects to the grid and starts to export power, the relay switches state and therefore closes (or opens).

When the inverter disconnects from the grid, the relay contact returns to its position of rest, namely open (or closed).

Production

Alarm

Config Alarm

The relay switches whenever there is an alarm on the inverter (Error). No switching occurs when there is a Warning.

If the relay contractor is in normally open(close)mode, the contact will stay open (or closed) until the inverter reports an error; once the inverter reports an error, the relay switches state and therefore closes (or opens).The contact remains switched from its rest condition until normal opera-tion is restored.

the relay switches whenever there is an alarm (Error) or a Warning, which have been previously selected by the user through the PC. the contact will stay open (or closed) until the inverter reports an error or a warning out of those selected from the menu; once the inverter displays an error or a warning out of those selected, the relay switches state and therefore closes (or opens) the contact. The relay remains switched from its rest condition until the alarm or warning has disappeared.

Outlines of this chapter

This topic describes how to perform daily maintenance and troubleshooting to ensure longterm proper operation of the Sunny Horse Series inverter.

If inverter does not display any Fault, please check the following lists.

- Is the inverter located in a clean, dry, adequately ventilated place?

- Is the DC switch turned ON?

- Are the cables adequately sized and short enough?

- Are the input and output connections and wiring in good condition?

- Are the configuration settings correct for the particular installation?

- Are the display panel and the communications cable properly connected and undamaged?

Follow the steps below to view recorded problems:

Press “ESC ” to enter the main menu in the normal interface. In the interface screen select “Event List”, then press “OK” to enter events.

Table 7-1 Eventlist

If the alarm occurs occasionally, the possible cause is that the electric grid is abnormal occasionally. SOFAR inverter automatically returns to normal operating status when the electric grid’s back to normal. If the alarm occurs frequently, check whether the grid voltage/frequency is within the acceptable range. If no, contact SOFAR technical support. If yes, check the AC circuit breaker and AC wiring of the SOFAR inverter. If the grid voltage/frequency is within the acceptable range and AC wiring is correct, while the alarm occurs repeatedly, contact SOFAR technical support to change the grid over-voltage, under-voltage, overfrequency, under-frequency protection points after obtaining approval from the local electrical grid operator.

Check whether too few PV modules are series connected in a PV string, thus the voltage(Vmp) of the PV string is lower than the minimum operating voltage of SOFAR inverter. If yes, adjust the number of series connected PV modules to increase the voltage of the PV string to fit the input voltage range of SOFAR inverter. SOFAR inverter automatically returns to normal o perating st atus after correct adjustments.

Check the AC wiring connection to the electric grid, if it’s correct, please contact SOFAR technical support.

Check whether too many PV modules are series connected in a PV string, thus the voltage(Voc) of the PV string is higher than the maximum input voltage of SOFAR inverter. If yes, adjust the number of series connected PV modules to decrease the voltage of the PV string to fit the input voltage range of SOFAR inverter. SOFAR inverter automatically returns to normal operating status after correct adjustments.

Check the input mode(parallel mode/ independent mode) setting of SOFAR inverter according to Section 6 of this user manual.

If the fault occurs occasionally, the possible cause is that the external circuits are abnormal occasionally. SOFAR inverter automatically returns to normal operating status after the fault is rectified. If the fault occurs frequently and lasts a long time, check whether the insulation resistance between the PV array and earth(ground) is too low, then check the insulation conditions of PV cables.
