Notes: The manual and other documents must be stored in a convenient place and be available at all times.

1.3 Safety

Appropriate Usage

The Astronergy PV Inverter converts DC Current from PV generator into AC current. The Astronergy PV Inverter is suitable for

mounting indoors and outdoors.

You can use the AC current gernerated as follows:

Energy flows into the house grid. The consumers connected, for example, household devices or lighting, consume the

energy. The energy left over is fed into the public grid. When the Astronergy is not gernerating any energy, e.g., at night, the

consumers which are connected are supplied by the public grid.The Astronergy does not have its own energy meter. When

energy is fed into the public grid, the energy meter spins backwards.

Energy is fed directly into the public grid. The Astronergy is connected to a separate energy meter. The energy produced is

compensated at a rate depending on the electric power company.

House grid:

Public grid

The Astronergy is connected to a stand-alone grid. A stand-alone grid is a grid which is not connected to a public grid ,the

Astronergy needs a grid-forming generator in order to function, The energy generated is consumed directly on site, surplus

energy can be stored in batteries.but the energy must not fed to the grid-forming generator. or it will destory the grid-forming

generator.

Alternative uses, modifications to the Astronergy PV inverter or the installation of component parts not expressly

recommended or sold by Astronergy are not permitted. Persons with limited physical or mental abilities may only work with

the Astronergy PV inverter following proper instruction and under constant supervision. Children are forbidden to play with

the Astronergy PV inverter. Keep the Astronergy PV inverter away from children.

DC and AC Switch

Separate the Astronergy CHPI KTL-M2 securely from the grid and the PV generators using DC and AC Switch. DC and AC Switch

shall be able to disconnect all unground conductors after installation.

Notes: The Astronergy CHPI KTL-M2 include a DC switch ,if you turn o it when inverter is working , please waiting 5 minutes

to turn on it again.

Grounding the PV modules

The CHPI KTL-M2 is a transformerless inverter. That is why it has no galvanic separation. Do not ground the DC circuits of the

PV modules connected to the CHPI KTL-M2. Only ground the mounting frame of the PV modules.

If you connect grounded PV modules to the CHPI KTL-M2, the error message “PV ISO Low”.

3. Unpacking and inspection

After opening the package, please check the contents of the box. It should contain the following:

Item Name Ouantity

A Solar inverter 1

B Mounting frame 2

C Safety-lock screws 2

D Mounting screws 4

E Mounting frame screws sleeve 4

F Monitor software(disk) 1 (Optional)

G manual 1

H Bluetooth 1 (Optional)

Notes: Please check all of the accessories carefully in the carton. If anything missing, contact your dealer at once. Thoroughly

inspect the packaging upon delivery, if you detect any damage to the packaging which indicates the inverter may be

damaged, inform the responsible transport company immediately. We will be glad to assist you if required.

4. INSTALLATION

4.1 Safety instructions

• All electrical installations shall be done in accordance with the local and national electrical codes. Do not remove the

casing. Inverter contains no user serviceable parts. Refer servicing to qualied service personnel. all wiring and electrical

installation should be conducted by a qualied service personnel .

• Carefully remove the unit from its packaging and inspect for external damage. If you nd any imperfections, please contact

your local dealer.

• Be sure that the inverters connect to the ground in order to protect property and personal safety.

• The inverter must only be operated with PV generator. Do not connect any other source of energy to it.

• Both AC and DC voltage sources are terminated inside the PV Inverter. Please disconnect these circuits before servicing.

• This unit is designed to feed power to the public power grid (utility) only. Do not connect this unit to an AC source or

generator. Connecting Inverter to external devices could result in serious damage to your equipment.

• When a photovoltaic panel is exposed to light, it generates a DC voltage. When connected to this equipment, a photovoltaic

panel will charge the DC link capacitors.

• Energy stored in this equipment’s DC link capacitors presents a risk of electric shock. Even after the unit is disconnected

from the grid and photovoltaic panels, high voltages may still exist inside the PV-Inverter. Do not remove the casing until at

least 5 minutes after disconnecting all power sources.

• Although designed to meet all safety requirements, some parts and surfaces of Inverter are still hot during operation.

To reduce the risk of injury, do not touch the heat sink at the back of the PV-Inverter or nearby surfaces while Inverter is

operating.

• According to VDE-AR-N 4105,password is given for protection. For CEI 0-21, no password needed.

4.2 Safety instructions

• The installation method and mounting location must be suitable for the weight and dimensions of the inverter. Select a

wall or solid vertical surface that can support the PV-Inverter.

• Mount on a solid surface, the mounting location must be accessible at all times.

• In living areas, do not mount the unit on plasterboard walls or similar to avoid audible vibrations. When in use, the inverter

emits noises which may be perceived as a nuisance in a living area.

• Vertical installation or tilted backwards by max. 15°.

• The connection area must point downwards.

• Do not install horizontally.

• Be sure that the inverter is out of the children’s reach.

• Don’t put any things on the inverter. Do not cover the inverter.

4.3 Safety instructions

• Inverter requires adequate cooling space. Providing better ventilation for the inverter to ensure the heat escape adequately.

The ambient temperature should be below 40°C to ensure optimum operation.

• Do not expose the inverter to direct sunlight, as this can cause excessive heating and thus power reduction.

• The ambient clearance needed is shown as following:

(a) Ambient dimensions of one inverter

(b) Ambient dimensions of a series inverters

There must be sucient clearance between the individual inverters to ensure that the cooling air of the adjacent inverter is

not taken in.

If necessary, increase the clearance spaces and make sure there is enough fresh air supply to ensure sucient cooling of the

inverters.

• Using the mounting frame as a template, drill 4 holes as illustrated in image.
