non-recoverable damage to the inverter.

When photovoltaic array configuration, make sure that the open-circuit voltage of
each photovoltaic group does not exceed the maximum DC input voltage of the
inverter. For the maximum DC input voltage of JNPxL and JNPxH series pv pump
inverters, please refer to the technical parameters of each type of inverters in the
appendix.
Warning
！
Improper installation environment of inverter will affect machine performance and may
cause machine damage.
Do not install the inverter in flammable, explosive or flammable, explosive storage
places.
Do not install the inverter in an area where it may be struck by lightning.
Do not install inverters in places with more salt fog.
Electrical connection
Danger
！
When installing photovoltaic arrays during the day, apply light-tight materials to cover
the solar array. Otherwise, the solar array will generate high voltage and cause
human casualties when exposed to sunlight.
Warning
！
Do not close any circuit breaker until all equipment is fully connected.
