Before Installation

There is a risk of injury if the product is mishandled!

y Always follow the instructions in the manual when moving and

positioning the inverter.

y The weight of the equipment can cause injuries, serious wounds, or

bruising if mishandled.

During Installation

Prior to securing the inverter to the wall, it is crucial to make certain that the inverter is not electrically connected.

System performance can be impaired by poor ventilation!

The equipment requires well ventilation during operation. It is essential to keep the unit upright and nothing covering the heat sink to let the equipment interior well cool down.

During Electrical Connection

Lethal voltage exists!

PV arrays will produce electrical energy when exposed to sunlight and thus can cause an electrical shock hazard.

y Wiring of the PV arrays should only be performed by qualified personnel.

All cables must be firmly attached, undamaged, properly insulated and adequately dimensioned.

Page 11

User Manual 1 Safety Instructions

During Inverter Operation

There is a risk of inverter’s damage or personal injury!

Do not disconnect DC connectors while the inverter is under AC load! First de-energize the equipment from the dual power sources and then verify that there is no voltage existing.

There is a risk of burns!

Avoid touching device hot parts (such as the heat sink) during operation. Only the LED indicator panel and the optional DC switch can be touched during inverter operation.

Maintenance and Service

y Any malfunction that may impair the inverter safety operation must be

repaired immediately before the inverter is restarted.

y Inverter contains no customer serviceable parts inside. Please contact

local authorized personnel if any service work is required.

Servicing of the device in accordance with the manual should never be undertaken in the absence of proper tools, test equipments or the more recent revision of the manual which has been clearly and thoroughly understood.

Page 12

1 Safety Instructions User Manual

There is a risk of inverter damage or personal injury due to incorrect service work!

Always keep in mind that the inverter is power supplied by dual power source: PV arrays and utility grid.

Before any service work, observe the following procedures.

y Disconnect the inverter from the utility grid side first and then PV arrays;

y Wait at least 10 minutes for inner capacitors to discharge completely;

y Verify that no voltage and current existing with appropriate testing

devices.

Keep non-related persons away!

A temporary warning sign or barrier must be posted to keep non-related persons away while performing electrical connection and service work.

Do not open the enclosure when the inverter is under voltage. There is a high likely risk of explosion in very specific cases of malfunction. The enclosure will protect persons and property from such an explosion, only if it is correctly sealed.

5.1 General Safety Instruction

Once the inverter is firmly attached to the appropriate location, it can be connected into the PV power system.

Prior to any electrical connection, keep in mind that the inverter has dual power supplies. It is mandatory for technical personnel to wear personal protective equipments: helmet, footwear and gloves during the electrical work.

Improper operation during the wiring process can cause fatal injury to operator or unrecoverable damages to the inverter.

All electrical installations must be in accordance with local and national electrical codes.

Only after being approved by the utility company and installed by qualified personnel can you connect the inverter to the utility grid.

All cables must be firmly attached, undamaged, properly insulated and adequately dimensioned.

These regulations should also be followed:

An appropriately sized AC circuit breaker is suggested as the protection equipment in AC connection, as shown in Fig. 5-2.

5.4.1 AC Side Requirements

Only after being approved by the local grid company can you connect the inverter to the grid.

Prior to connecting the inverter to the utility grid, verify whether the grid voltage and frequency are within the range of inverter output parameters (refer to Appendix). Consult the local grid company for solution if otherwise.

Residual Current Device

With an integrated universal current-sensitive residual current monitoring unit inside, the inverter is able to distinguish the fault current from normal capacitive leakage current. The inverter will disconnect immediately from the mains when a fault current out of the limit value has been detected.

However if an external RCD or residual current breaker is mandatory, the switch must be triggered at a failure current of 300mA or higher.

5.4.2 Assembling AC Cables to Connector

Inverter is equipped with water-proof direct plug-in connectors for AC connection, which match AC terminals at the bottom of the inverter.

“L”, “N” and “PE” should be equipped with correctly colored cables for distinguishing. Please refer to related standards for specific wiring color.

AC Cable Requirements

Select AC cable specifications and types considering the following facts:

Page 38

5 Electrical Connection User Manual

The grid impedance of the AC cable must correspond to the specification to avoid unintended disconnection from the grid or derating of the output power.

Step 10 Connect phase cable and “N” cable to AC circuit breaker.

Step 11 Connect AC circuit breaker to utility grid.

Step 12 Make sure all AC cables are firmly installed.

5.5 Connecting Inverter to PV Arrays

Lethal voltage exists!

PV arrays produce electrical energy when exposed to light and thus can create an electrical shock hazard. Wiring should only be performed by qualified personnel.

Before connecting the PV arrays to the inverter, make sure that the impedances between the positive terminal of the PV string and Earth and the impedances between the negative terminal of the PV string and Earth are larger than 200Kohm.

There is a risk of inverter damage! The following requirements should be met; otherwise they will lead to loss of any and all warranty rights.

y Make sure that the maximum short circuit current of each DC input is less than

inverter allowable limit.

y Make sure that the maximum open voltage of each string is less than 1000V.

Voltage over 1000V can damage the inverter.

If the input line is changed, such as input line falls off, etc. You need to reset the work mode.

5.5.1 PV Inputs Configuration

For -S series inverters, there’s one input area with one MPP tracker. They can be configured in parallel mode only.

For –D series inverters, there’re two PV input areas, each owning its MPP tracker. The

Page 41

User Manual 5 Electrical Connection

two PV inputs can be configured in independent mode or parallel mode.

PV Configuration Mode-Independent Mode

For independent mode, the two PV inputs work independently, each with its own MPPT. Therefore the two PV inputs can be different from each other in PV module types, numbers of PV panels in PV string, tilt angles and orientation angle of PV modules.

As shown in the following diagram, the inverter should be configured to independent mode due to different orientation angle between the two PV inputs.

To make sure the maximum DC power, PV strings connected to individual input area should have a homogenous structure, i.e. the same type, identical tilt and identical orientation.

Make sure that none of the DC or AC cables connected to the inverter is live before the electrical work.

Connect the inverter to PV array as the following procedures:

Step 1 Rotate the optional DC switch at the bottom to the “OFF” position.

Step 2 Check the connection cable of PV string for the correct polarity and that the

open-circuit voltage does not exceed the inverter input limit 550V, even under the lowest operating temperature. Refer to module specification supplied by module manufacturer for detailed information.

y Check the positive and negative polarity of the PV cells. After confirmation,

you can insert the DC connectors into the input terminals on the bottom of the inverter.

y For the same MPPT, reverse connection of a single string is prohibited. A

permanent failure of the system or inverter may follow if otherwise.

Step 3 Plug the positive and negative DC connectors into corresponding terminals

until there is an audible click.

* Image shown here is for reference only. Actual product you receive may differ.

5.6 Grounding of Inverter

Because of the transform-less design of the inverter, DC positive pole and DC negative pole are not permitted to be grounded. A permanent destroy to the inverter may follows if otherwise.

All non-current carrying exposed metal parts of the equipment and other enclosures in the PV power system should be grounded (e.g., PV arrays frame and inverter enclosure).
