Anti-Islanding Effect
►
Islanding effect is a special phenomenon that grid-connected 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.
X3-Retro Fit seires inverter provide Active Frequency Drift(AFD) to prevent
islanding effect.
PE Connection and Leakage Current
High leakage current!
Earth shall be connected before connecting to any power.

• 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
regulations.
• Do not connect the ground terminals of the unit in series in case of a multiple
installation. 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.
• No protection settings can be altered.
• User shall ensure 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
►
SolaX X3-Retro Fit series inverter can only work with high voltage battery, for
the specific parameters such as battery type, nominal voltage and nominal
capacity etc., please refer to section 4.2.
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 off load connected to the batteries before dismantling battery
connection terminals.
6: Only qualified personnel with proper knowledge can carry out the
maintenance of batteries.
• All inverters incorporate a certified internal Residual Current Device(RCD) in
order to protect against possible electrocution and fire hazard in case of a
malfunction in the PV array, cables or inverter.There are 2 trip thresholds for
the RCD as required for certification (IEC 62109-2:2011). The default value for
electrocution protection is 30mA,and for slow rising current is 300mA.
• If an external RCD is required by local regulations,check which type of RCD is
required for relevant electric code. It recommends using a type-A RCD. The
recommended RCD values is 100mA or 300mA unless a lower value is required
by the specific local electric codes. When required by local regulations, the use
of an RCD type B is permitted.
