Please contact the nearest authorized service center if any maintenance or repair is

needed. Contact your distributor for the information of the nearest authorized

service center. Do NOT repair it by yourself, it may cause injury or property

damage.

Before installing and maintaining the equipment, you should turn the DC switch

OFF to cut off the high voltage DC of the PV array. You can also turn the switch in

the PV combiner box OFF to cut off the high voltage DC. When the battery needs

to be installed, please confirm the positive and negative terminals of the battery and

turn OFF the battery. Otherwise, serious injury may be caused.

Qualified persons

The customer must make sure the operator has the necessary skill and training to do

his/her job. Staff in charge of using and maintaining the equipment must be skilled,

aware and mature for the described tasks and must have the reliability to correctly

interpret what is described in the manual. For safety reason only a qualified

electrician, who has received training and / or has demonstrated skills and

knowledge in construction and in operation of this unit, can install this inverter.

Shenzhen SOFARSOLAR Co., Ltd. does not take any responsibility for the

property destruction and personal injury because of any incorrect use.

Installation requirements

Please install inverter according to the following section. Fix the inverter on an

appropriate objects with enough load bearing capacity (such as walls, PV racks

etc.), and ensure that inverter is vertical placed. Choose a place suitable for

HYD 5-20KTL-3PH User manual

installing electrical devices. And assure there is enough fire exit space, convenient

for maintenance. Maintain proper ventilation to ensure enough air cycle to cool the

inverter.

Transport requirements

If you find packing problems that may cause the damage of the inverter, or find any

visible damage, please immediately notice the responsible transportation company.

You can ask solar equipment installation contractor or Shenzhen SOFARSOLAR

Co. , Ltd. for help if necessary.

Transport of the equipment, especially by road, must be carried out with by suitable

ways and means for protecting the components (in particular, the electronic

components) from violent shocks, humidity, vibration, etc.

Labels on the equipment

Electric connection

Please comply with all the current electrical regulations about accident prevention

in dealing with the solar invert.

Before the electrical connection, make sure to use opaque material

to cover the PV modules or to disconnect PV array DC switch.

Exposure to the sun, PV array will produce a dangerous voltage!

Danger

The labels must NOT be hidden with objects and

extraneous parts(rags, boxes, equipment, etc.);they

must be cleaned regularly and kept visible at all

times.

HYD 5-20KTL-3PH User manual

All installation accomplished only by professional electrical

engineer!

Must be trained;

Completely read the manual operation and understand relevant

matter.

Warning

Get permission from the local electrical grid operator, complete all

electrical connections by professional electrical engineer, then

connect inverter to electrical grid.

Attention

It’s forbidden to remove the tamper evident label, or open the

inverter. Otherwise SOFARSOLAR will not provide warranty or

maintenance!

Note

Operation

Touching the electrical grid or the terminal of the equipment may

lead to electrocution or fire!

Don’t touch the terminal or conductor connected to the electrical

grid.

Pay attention to any instructions or safety documents related to grid

connection.

Danger

Some internal components will be very hot when inverter is

working. Please wear protective gloves!

Keep it away from kids !

Attention

Maintenance and repair

Before any repair work, turn OFF the AC circuit breaker between

the inverter and electrical grid first, then turn OFF the DC switch.

After turning OFF the AC circuit breaker and DC switch, wait for 5

minutes at least before carrying out any maintenance or repair work.

for the losses from that.

Attention

EMC / noise level of inverter

Electromagnetic compatibility (EMC) refers to that one electrical equipment

functions in a given electromagnetic environment without any trouble or error, and

impose no unacceptable effect upon the environment. Therefore, EMC represents

the quality characters of an electrical equipment. The inherent noise-immune

character: immunity to internal electrical noise. External noise immunity: immunity

HYD 5-20KTL-3PH User manual

to electromagnetic noise of external system. Noise emission level: influence of

electromagnetic emission upon environment.

Electromagnetic radiation from inverter may be harmful to

health!

Please do not continue to stay around the inverter in less than 20 cm

when inverter is working.

Danger

1.2. Symbols and signs

Caution of burn injuries due to hot enclosure!

You can only touch the screen and pressing key of the inverter while

it’s working.

Caution

PV array should be grounded in accordance to the requirements of

the local electrical grid operator!

We suggest that all PV module frames and inverter are reliably

grounded

protect

the

system

and

personnel

security.

Attention

Ensure input DC voltage < Max. DC voltage .Over voltage may

cause permanent damage to inverter or other losses, which will not

be included in warranty!

Warning

Signs on the inverter

There are some symbols which are related to security on the inverter. Please read

and understand the content of the symbols, and then start the installation.

This symbol indicates a hazardous situation which could result in

injuries, if not avoided.

There is a residual voltage in the inverter! Before opening the

equipment, operator should wait for five minutes to ensure the

capacitor is discharged completely.

Caution, risk of electric shock.

Caution hot surface.

Comply with the Conformite Europeenne (CE) certification.

Grounding point.
