Assembly and maintenance notes
In case of maintenance or repair, contact your service centre. Contact your nearest distributor for
information or assistance. DO NOT repair the device yourself, as this may cause injury or damage to
property.
The inverter must be completely disconnected (BAT, PV and AC) during maintenance. Before
maintenance, disconnect the AC connection first, then the battery and the DC photovoltaic system (PV1
and PV2), and wait at least 5 minutes (capacitor discharge time) to avoid electric shock.
The inverter may reach high temperatures and have rotating parts inside during operation. Switch off
the 3PH HYD5000-HYD20000-ZSS inverter and wait for it to cool down before performing any
maintenance.
The inverter and batteries must be located in well-ventilated areas. Do not place the inverter in a
cabinet or in an airtight or poorly ventilated location. This could be extremely hazardous to the
performance and life of the system.
Use a multimeter to check the polarity and voltage of the battery before turning on the power, and also
the PV voltage and polarity before closing the PV switch. Make sure that the connections are carried
out according to the instructions in this manual and refer to the detailed installation notes available at
If you want to store the batteries without using them, disconnect them from the 3PH HYD5000-
HYD20000-ZSS inverters and store in a cool, dry and well-ventilated area.
Secure the inverter to appropriate objects with sufficient load capacity (walls, PV brackets, etc.) and
ensure that it is positioned vertically.
Attention:
follow the rules below during installation/maintenance of the battery:
