●Measure the voltage between terminals Vdc+ and Vdc- with a multi-meter
(impedance at least 1Mohm) to ensure that the device is discharged before
beginning work (35Vdc) inside the device.
Surge Suppression Devices (SPD)
Thunder will cause a damage either from a direct strike or from surges due to a nearby
strike Induced surges are the most probable cause of thunder 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.
●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 to EN 61632-1.
●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.
Battery Safety Instructions
PhG-P hybrid inverter series should be worked with high voltage battery, for the specific
parameters such as battery type, nominal voltage and nominal capacity etc., please
refer to parameters of the products.
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 maintain or replacement:
●Do not wear watches, rings or similar metallic items.
●Use insulated tools.
●Put on rubber shoes and gloves.
