2 Safety

2.1 Appropriate Usage

The inverters are PV inverters which can convert the DC current of the PV generator into AC current and feed it into the public grid.

Surge protection devices (SPDs) for PV installation

WARNING!

Over-voltage protection with surge arresters should be provided when the PV power system is installed. The grid connected inverter is fitted with SPDs in MAINS side.

Induced surges are the more likely cause of lightning damage in the majority of installations, especially in rural areas where electricity is usually provided by long overhead lines. Surges may be induced on both the PV array conductors or the AC cables leading to the building.

Specialists in lightning protection should be consulted in the actual application. Using appropriate external lightning protection, the effect of a direct lightning strike into a building can be mitigated in a controlled way, and the lightning current can be discharged into the ground.

Installation of SPDs to protect the inverter against mechanical damage and excessive stress includes a surge arrester in the case of a building with external lightning protection system (LPS) when separation distance is kept.

To protect the DC system, surge protection device (SPD type 2) should be fitted at the inverter end of the DC cabling and at the array located between the inverter and the PV generator, if the voltage protection level (VP) of the surge arresters is greater than 1100V, an additional SPD type 2 is required for surge protection for electrical devices.

To protect the AC system, surge protection devices (SPD type 2) should be fitted at the main incoming point of AC supply (at the consumer's cutout), located between the inverter and the meter / distribution system; SPD (test impulse D1) for signal line according to EN 61632-1.

Spark gap protection devices are not suitable to be used in DC circuits once conducting, they won't stop conducting until the voltage passes through their terminals typically less than 30 volts.

Safety Safety

- Anti-Islanding Effect

Islanding effect is a special phenomenon that grid-connected PV system still supplies power to the nearby grid when electrical grid power is no longer present. It is dangerous for maintenance personnel and the public.

The inverter provides Active Frequency Drift (AFD) to prevent islanding effect.

WARNING!

Hazardous voltage will present for up to 5 minutes after disconnection from power supply.

- CAUTION-RISK of electric shock from energy stored in capacitor. Never operate on the solar connectors, the MAINS cables, PV cables or the PV generator when power is applied. After switching off the PV and MAINs, always wait 5 minutes to let the intermediate circuit capacitors discharge before you unplug DC and MAINS connectors.

- Strictly prohibit the dismantling. Even in the unlikely event that you have to dismantle the machine, you must not touch any internal parts.

PE Connection and Leakage Current

- The inverter incorporates a certified internal Residual Current Device (RCD) in order to protect against possible electrocution and fire hazards in case of a malfunction in the cables or the inverter. There are two-trip thresholds for the RCD as required for certification (IEC 62109-2: 2011).

• The default value for electrocution protection is 30 mA, and for slow rising current is 300 mA.

• If an external RCD is required by local regulations, check which type of RCD is required for relevant electric code. It recommends using a type-A RCD. The recommended RCD value is 300 mA unless a lower value is required by the specific local electric codes. When required by local regulations, the use of an RCD type B is permitted.

The device is intended to connect to a PV generator with a capacitance limit of approx 700 nF.

WARNING!

7. Start the Inverter

- After the inverter is checked, then conduct the following steps.

a) Check that device is fixed well on the wall or stand.
b) Make sure all the DC breakers and AC breakers are disconnected.
c) AC cable is connected to grid correctly.
d) All PV panels are connected to inverter correctly, DC connectors which are
not used should be sealed by cover.
e) Turn on the DC switch to the "On" position.

- Start the inverter

Turn on the AC switch between the inverter and the power grid.

Turn on the DC switch between the PV string and the inverter if there is any.

Turn on the DC switch at the bottom of the inverter.

Inverter will start automatically when PV panels generate enough energy.

Check the status of LED indicators and LCD screen, the LED indicators should be

blue and the LCD screen should display the main interface.

For the inverter with LED indicators:

If the LED indicator is not on, please check the below:

• All the connections are right.
• All the external circuit breakers are closed.
• The DC switch of the inverter is in the "ON" position.

1. FTR indicator status indicators definition
Communication signal Indicator (Vcc)	Always light or	The inverters communication is named
	- Idosing	The communication data is sent to the secret for calling it.
DC power signal indicator (gpre)	Always light or	The inverters in grid connected state.
	- Idosing	If the fault signals light is on, if indicators errors occur on the inverters LCC state, if the fault signal light is off, it indicates no errors occur on the inverters LCC state and at least one channel of MFP1 linear voltage is higher than 200 V.
	Always light or	The input voltage at all channels of MFP1 is less than 200 V, DC X switch is not turned on.
Grid connection indicator (gpre)	Always light or	The inverters in grid connected state.
	- Idosing	If the fault signals in other states is on, it indicates errors occur on the inverters AC state, if the fault signal indicator is off, AC Q will be connected and the inverters is not in grid connected state.
	Always light or	The inverters are connected to the part.
Lowest fault indicator (RCC)	Always light or	The inverters is faulty.
	- Idosing	The inverters cannot warning.
	Always light or	The inverters is currently in a normal state, and there is no fault.

Note:

1 When the inverter is in software upgrading state, all the indicators are blinking by horse racing LED in circle;
2 When the inverter upgrade fails, other three indicators will be off except the inverter fault indicator (Red);
3 After the inverter upgrade succeeded, all the indicators will be off;
4 When the inverter is in the aging mode, the inverter fault indicator (Red) is
flashing and other indicators keep the current state.

Startup of the Inverter

Startup of the Inverter

For the inverter with LCD screen:

Below is the three different states when operating, which means inverter starting up successfully.

Waiting: Inverter is waiting before checking when DC input voltage from panels is greater than 160 V (lowest start-up voltage) but less than 200 V (lowest operating voltage).

Checking: Inverter will check DC input environment automatically when DC input voltage from the PV panels exceeds 200 V and PV panels have enough energy to start inverter.

Normal: Inverter begins to operate normally, meanwhile the LCD displays the main interface. Enter the setting interface to set the parameters when it is the first time to start up.

Object	Name	Description
A	LCD Screen	Display the information of the inverter.
B	ESC key	Return to the previous interface or cancel the setting
C	Up key	Move the cursor up or increase the setting value.
D	Down key	Move the cursor down or decrease the setting value.
E	Enter key	Enter the selected interface or confirm the setting.

8. Firmware Upgrading

• Upgrade preparation
  1) Prepare a U disk (USB 2.0 / USB 3.0);

CAUTION!

Please make sure that the format is FAT or FAT 32.

2) Contact our service support to get the update files ("*.bin" and "*.txt" file), and store the two files in the root path of the U disk.

Files:

FORTH_Vxxx.xx.bin

UpdateConfig.txt

CAUTION!

The bin name listed in the "*.txt" file must be same as the "*.bin" name.

• Upgrade steps
  USB disk can be plugged when the inverter is in normal status.
  1) Plug the U disk into the upgrading port below: If the Wi-Fi dongie is connected to the port, please remove the dongie first.

NOTE!

After U disk plug in, the four indicator lights will be blinking in turn. (Communication indicator: blue; DC connection indicator: green; Grid connection indicator: green; Alarm indicator: Red)

2) Wait approximately 15 seconds. The system will start upgrading when the four indicator lights turn off and the buzzer starts buzzing.
3) When the buzzer stops buzzing and the indicator lights start blinking again, it means that ARM program is upgraded successfully. And then the system will start other programs by upgrading.

If upgrading succeeds, the communication indicator (blue) turns off and other indicators are on;

If upgrading fails, only alarm indicator (red) is on. Please contact our service support for solutions.

NOTE!

After upgrading finished, the current state of indicator will be kept for 1 min and the inverter will be switched on automatically.
