Frequently Asked Questions - IQ 5.5 Kostal

How to install the Kostal IQ 5.5 inverter correctly?

Installation must be carried out by a qualified electrician. Follow the instructions in the Installation chapter on page 56. Ensure safety distances are respected and use a suitable circuit breaker.

What safety precautions should be taken before any intervention?

Before any intervention, power off the device and wait 5 minutes to allow capacitor discharge. Wear personal protective equipment. The inverter can reach temperatures above 80 °C during operation.

Can the inverter be used outdoors?

Yes, the inverter has IP65 protection allowing it to withstand weather conditions. However, avoid direct sunlight exposure and ensure adequate ventilation.

How to clean the inverter?

Regularly clean the ventilation openings with a dry soft cloth. Do not use aggressive cleaning products. Ensure the device is powered off.

What to do in case of a fault or error message?

Consult the inverter's integrated web server for detailed error information. If necessary, contact the after-sales service at the numbers indicated in the manual.

What is the maximum power of connectable solar panels?

The maximum power depends on the input voltage and current. For the IQ 5.5, the rated power is 5.5 kW. Respect the DC voltage limits (max 1000 V) and current (not specified, but generally about 15 A per tracker).

How to access the inverter's web interface?

Connect the inverter to your network via Ethernet. Open a browser and enter the inverter's IP address (by default, it is assigned by DHCP). See page 69 of the manual for details.

What type of circuit breaker should be installed on the AC side?

A circuit breaker suitable for the inverter's rated current. The manual recommends a residual current device (RCD) type A ≥ 300 mA.

Is the inverter compatible with batteries?

The IQ 5.5 model is a standard solar inverter without integrated battery management. For storage, hybrid inverters are required.

Where to find the warranty terms?

Warranty terms are available on the Kostal website: www.kostal-solar-electric.com > Download > PIKO IQ > model > country > Warranty. The standard warranty is generally 5 years.

DE Kurzanleitung 4

The PIKO inverter converts direct current into alternating current. This can be used as follows:

■ for self-consumption
■ for feed-in into the public grid

The device may only be used in grid-connected photovoltaic systems within the permissible power range and under the permissible ambient conditions. The device is not intended for mobile use.

Inappropriate use may lead to injury or even death to the user or third parties. Material damage to the device and other equipment can also occur. The inverter may therefore only be used for its intended purpose.

All components fitted on the inverter or in the PV system must satisfy the standards and guidelines that apply in the country of installation.

Labels on the inverter

Signs and labels are affixed to the housing of the inverter.

These signs and labels must not be altered or removed.

Safety instructions

DANGER!

RISK OF DEATH DUE TO ELECTRICAL SHOCK AND DISCHARGE

Life-threatening voltages are present in the inverter. Only a qualified electrician may open and perform work on the device.

Always de-energise the device during installation, maintenance and repairs, and secure it against being switched back on.

The PV generators/cables may be live as soon as they are exposed to light.

DC cables must never be connected to or disconnected from the device during operation, as dangerous arcs may form. De-energise DC side, then mount or remove plug connector!

WARNING!

RISK OF BURNS FROM HOT PARTS

Allow device to cool before any maintenance or repair work.

RISK OF BURNS FROM HOT PARTS ON THE DEVICE

Some of the inverter components can reach temperatures of over 80^ C during operation. Select the installation site in accordance with the information provided in these instructions. Always keep the ventilation openings clear.

RISK OF FIRE DUE TO OVERCURRENT AND HEATING OF THE MAINS CABLE

Install line circuit breaker to secure against overcurrent.

RISK OF FIRE DUE TO IMPROPER INSTALLATION

Incorrectly fitted plugs and sockets may heat up and cause a fire. During installation, be sure to follow the manufacturer's requirements and manual.

WARNING!

INJURIES CAN RESULT FROM DESTRUCTION OF THE DEVICE

When the maximum values for the permitted input voltage at the DC inputs are exceeded, this can result in serious damage, which may destroy the device and cause serious injury to any person present. Even briefly exceeding the voltage may cause damage to the device.

IMPORTANT INFORMATION

The inverter may only be installed, maintained and repaired by a trained and qualified electrician. The electrician is responsible for ensuring that the applicable standards and regulations are observed and implemented. Work that could affect the electrical power system of the relevant energy supply company at the site of the solar power feed-in may only be carried out by qualified electricians expressly authorised (licensed) by the energy supply company. This includes changes to the factory pre-set parameters, e.g. using the PARAKO parameterisation software.

It must be ensured that the L1-L3 phases on the inverter's AC terminal and the phases in the grid are assigned uniformly.

If residual current protection equipment (RCD) is used, a type A RCD ≥300 mA can be used on the AC side. Use of a type A RCD is set in the Webserver. (Default setting: compatibility with type A RCD).

The solar modules connected to the inverter must comply with Class A of the IEC 61730 standard.

For initial commissioning, at least the "min. input voltage (U DCmin)" must be present and there must be an output greater than the self-consumption of the inverter.

POSSIBLE DAMAGE

Risk of damage when the inverter is placed on its underside. Always place the inverter on its rear side (cooling elements) after unpacking.

If the PV generators are incorrectly connected, the inverter may be damaged. Check the connections before commissioning.

Installation

Perform inverter assembly, installation and commissioning based on the information provided in the Installation chapter on page 56 onwards
