Safety
2.1 Appropriate Usage
The X1 Series are PV inverters which can convert the DC current of the PV
generator into AC current and feed it into the public grid.
Surge protection devices (SPDs) for PV installation
WARNING!
- Over-voltage protection with surge arresters should be provided when the PV power system is installed.
- The grid connected inverter is tted with SPDs in MAINS side.
Lightning will cause a damage either from a direct strike or from surges due
to a nearby strike.
Induced surges are the most likely cause of lightning damage in majority or
installations, especially in rural areas where electricity is usually provided
by long overhead lines. Surge may be included on both the PV array conduction
and the AC cables leading to the building.
Specialists in lightning protection should be consulted during the end use
application. Using appropriate external lightning protection, the effect of a
direct lightning strike into a building can be mitigated in a controlled way,
and the lightning current can be discharged into the ground.
Installation of SPDs to protect the inverter against mechanical damage and
excessive stress include a surge arrester in case of a building with external
lightning protection system (LPS) when separation distance is kept.
To protect the DC system, surge suppression device (SPD type2) should be tted
at the inverter end of the DC cabling and at the array located between the
inverter and the PV generator, if the voltage protection level (VP) of the
surge arresters is greater than 1100V, an additional SPD type 3 required for
surge protection for electrical devices.
To protect the AC system, surge suppression devices (SPD type2) should be tted
at the main incoming point of AC supply (at the consumer’s cutout), located
between the inverter and the meter/ distribution system; SPD (test impulse D1)
for signal line according to EN 61632-1.
All DC cables should be installed to provide as short a run as possible, and
positive and negative cables of the string or main DC supply should be bundled
together. Avoid creating loops in the system. This requirement for short runs
and bundling includes any associated earth bundling conductors.
Spark gap devices are not suitable to be used in DC circuits once
conducting,they won’t stop conducting until the voltage passes through their
terminals typically less 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 electrical grid power is no longer
present. It is dangerous for maintenance personnel and the public.
X1 series provide Active Frequency Drift(AFD) to prevent islanding effect.
2.2 Important Safety Instructions

WARNING!
Hazardous voltage will present for up to 5 minutes after disconnection from
power supply.
- CAUTION-RISK of electric shock from energy stored in capacitor. Never operate on the solar inverter couplers, The MAINS cables, PV cables or the PV generator when power is applied. After switching off the PV and Mains, always wait for 5minutes to let the intermediate circuit capacitors discharge before you unplug DC and MAINS couplers.
- When accessing the internal circuit of solar inverter, it is very important to wait 5 minutes before operating the power circuit or demounting the electrolyte capacitors inside the device. Do not open the device beforehand since the capacitors require time to suffciently discharge!
- Measure the voltage between terminals UDC+ and UDC- with a multi-meter (impedance at least 1Mohm) to ensure that the device has totally discharged.PE Connection and Leakage Current
- The inverter incorporates a certiernal Residual Current Device (RCD) in order to protect against possible electrocution and e hazard in case of a malfunction in the cables or the inverter. There are two trip thresholds for the RCD as required for certiThe default value for eletrocution protection is 30 mA, and for slow rising current is 300 mA.
- If an external RCD is required by local regulations, check which type of RCD is required for relevant eletric code. It recommends using a type-A RCD. The recommended RCD values is 100 mA unless a lower value is required by the specitric codes.
The device is intended to connect to a PV generator with a capacitance limit
of approx 700nf.
