Before installation and maintenance of inverters, the connection of DC input and
AC grid must be disconnected, and the inverter shall not be touched for at least
5 minutes after the disconnection.
The local temperature may be higher when the inverter is running. Please don't
touch it so as not to be burned.
Installation site should be avoided as far as possible children and take
appropriate anti-static measures.
When configuring PV array,
we must ensure that the open circuit voltage of each
PV string does not exceed the maximum input voltage of the inverter, otherwise it will
cause the inverter to be unrecoverable.
To ensure that the DC input voltage is less than the maximum input voltage of
the inverter, otherwise it will damage the inverter, which Jntech
won’t bear the
responsibility and quality assurance.
PV array directly generated by the sun will produce DC high-voltage, need to
operate according to our provisions, to avoid partial protection measures failure.
In the case of unauthorized, do not remove the lid; do not touch or replace any
components except terminals outside, otherwise it will cause harm to the human
body and the inverter, which Jntech will not undertake the responsibility and
quality assurance department.
When the inverter works, do not plug in or out connector from PV, battery AC
terminal.
Please do not arbitrarily use inverter for other purposes.
In order to ensure safe operation, it is required correct grounding, using proper
conductor size and providing necessary short circuit protection.
