• 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.
