V-TAC VT-6608303, Instruction Manual

• "Danger" indicates a hazardous situation which, if not avoided, will result in 

death or serious injury.

• "Warning" indicates a hazardous situation which, if not avoided, could result 

in death or serious injury.

• "Caution" indicates a hazardous situation which, if not avoided, could result 

in minor or moderate injury..

• Danger to life due to high voltages in the inverter! 

• All work must be carried out by qualified electrician. 

• The appliance is not to be used by children or persons with reduced physical 

sensory or mental capabilities, or lack of exrerience and knowledge, unless 

they have been given supervision or instruction. 

• Children should be supervised to ensure that they do not play with the 

appliance.

• Danger of burn injuries due to hot enclosure parts! 

• During operation, the upper lid of the enclosure and the enclosure body may 

become hot. 

• Only touch the lower enclosure lid during operation.

• Possible damage to health as a result of the effects of radiation! 

• Do not stay closer than 20 cm to inverter for any length of time.

• Ensure input DC voltage ≤Max. DC voltage .Over voltage may cause perma

-

nent damage to inverter or other losses, which will not be included in warran-

ty!

• Authorized service personnel must disconnect both AC and DC power from 

inverter before attempting any maintenance or cleaning or working on any 

circuits connected to inverter.

• Do not operate the in verter when the device is running

• Over-voltage protection with surge arresters should be provided when the PV 

power system is installed.

• The grid connected inverter is not fitted with SPDs in both PV input side and 

MAINS side.

• High leakage current! Earth connection essential before connecting supply.

Note

！

• "Note" provides tips that are valuable for the optimal operation of our 

product.

• Grounding the PV generator.

• Comply with the local requirements for grounding the PV modules and the PV 

generator. It is recommends connecting the generator frame and other 

electrically conductive surfaces in a manner which ensures continuous conduc-

tion and ground these in order to have optimal protection of system and 

persons.

I Version applies to the wiring rules that requires Neutral line of alternative supply must 

NOT be isolated or switched (applies to wiring rules AS/NZS_3000:2012 for Australia and 

New Zealand).

Note!

• Please control the home loads, and make sure it's within the "EPS output 

rating" under EPS mode, otherwise the inverter will shutdown with an 

"overload fault" warning.

• Please confirm with the mains grid operator whether there is any special 

regulations for grid connection.

Inverter provides multiple work modes based on different requirements.

Work Modes

Work modes: Self-use (with PV Power)

Priority: load>battery>grid 

This mode applies the area that has low feed-in tariff 

and high energy price. The power generated from PV 

will be used to supply the local loads firstly, then to 

charge the battery. The redundant power will export to 

the public grid.

Work modes: Self-use (without PV Power) 

When no PV supplied, battery will discharge for local 

loads firstly, and grid will supply power when the 

battery capacity is not enough
