● Each WIT Inverter must be equipped with an AC circuit breaker. Multiple
WIT Inverters cannot connect to the same AC circuit breaker.
● Do not connect the load between the WIT Inverter and the circuit breaker.
● If the cable is thick, do not shake the cable terminals after tightening them.
Otherwise, the loose connection may cause overheating and device damage.
Ensure that the terminals are properly connected before starting the WIT
Inverter.
● Ensure the correct polarity of the terminals before connecting the PV array to
the WIT Inverter.
Maintenance and replacement:
● It must be operated by qualified and trained electrical technicians.
Technicians should observe instructions in this manual and local regulations.
● After turning off the DC switches and the AC breakers, wait for at least five
minutes before performing any operations to avoid risks.
● When the OLED screen indicates “PV Isolation low”, do not touch the
chassis as a ground fault may have been detected.
● Beware of high voltages which may cause electric shocks.
● To ensure good dissipation, clean the fan regularly.
● Do not use the air pump to clean the fan. Otherwise, the fan may be
damaged.
Others：
● Upon receiving the product, check if the contents are intact and complete. If
any damage is found or any component is missing, please contact your
distributor.
● The maximum PV input voltage cannot exceed 1100V. The battery input
voltage cannot exceed 1000V.
● For the WIT Inverter that will not be put into operation in the future, you
should properly dispose of them by yourself.
