V-TAC VT-6608303, Instruction Manual

• Avoiding the creation of loops in the system.

• Spark gap devices are not suitable to be used in DC circuits once conducting, they won't 

stop conducting until the voltage across their terminals is typically more than 30 volts.

• Anti-Islanding Effect Islanding effect is a special phenomenon that grid-connected PV 

system still supply power to the nearby grid when the voltage loss is happened in the 

power system. It is dangerous for maintenance personnel and the public. X1-Hybrid 

series inverter provide Active Frequency Drift(AFD) to prevent islanding effect.

PE Connection and Leakage Current

• The end-use application shall monitor the protective conductor by residual current 

operated protective device (RCD) with rated fault current Ifn≤240mA which automatically 

disconnects the device in case of a fault. The device is intended to connect to a PV 

generator with a capacitance limit of approx 700nf.

• Incorrect grounding can cause physical injury, death or equipment malfunction and 

increase electromagnetic.

• Make sure that grounding conductor is adequately sized as required by safety regula

-

tions.

• Do not connect the ground terminals of the unit in series in case of a multiple installa-

tion. This product can cause current with a d.c component, Where a residual current 

operated protective (RCD) or monitoring (RCM) device is used for protection in case of 

direct or indirect contact, only an RCD or RCM of type B is allowed on the supply side of 

this product. For United Kingdom

• The installation that connects the equipment to the supply terminals shall comply with 

the requirements of BS 7671.

• Electrical installation of PV system shall comply with requirements of BS 7671 and IEC 

60364-7-712.

• No protection settings can be altered.

• User shall ensur e that equipment is so installed, designed and operated to maintain at 

all times compliance with the requirements of ESQCR22(1)(a). For Australia and New 

Zealand

• Electrical installation and maintenance shall be conducted by licensed electrician and 

shall comply with Australia National Wiring Rules. Battery Safety Instructions VT series 

inverter should be worked with high voltage battery, for the specific parameters such as 

battery type, nominal voltage and nominal capacity etc., please refer to section 4.3. As 

accumulator batteries may contain potential electric shock and short-circuit current 

danger, to avoid accidents that might be thus resulted, the following warnings should be 

observed during battery replacement: 

1: Do not wear watches, rings or similar metallic items. 

2: Use insulated tools. 

3: Put on rubber shoes and gloves. 

4: Do not place metallic tools and similar metallic parts on the batteries. 

5: Switch o ffload connected to the batteries before dismantling battery connection 

terminals. 

6: Only personal with proper expertise can carry out the maintenance of accumulator 

batteries.
