•The unit contains capacitors that remain charged to a potentially lethal voltage after the
MAINS , battery and PV supply has been disconnected.
•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
inverter couplers, the MAINS cables, Battery cables, PV cables or the PV generator when
power is applied. After switching offthe PV , battery and Mains, always wait for 5minutes
to let the intermediate circuit capacitors discharge before unplug DC ,battery plug and
MAINS couplers.
•When accessing the internal circuit of 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 sufficiently
discharge!
•Measure the voltage between terminals UDC+ and UDC- with a multi-meter(impedance
at least 1Mohm) to ensure that the device is discharged before beginning work (35VDC)
inside the device.

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 fitted 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 fitted 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 in according
l 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. 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. Revo-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 about
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
