Safety Instructions
 Please read all the installation instructions in this ESS user manual before installing or
maintaining your system.

 The ESS should be opened by qualified electrical technicians only.

 When the photovoltaic array is exposed to light, it supplies a d.c. voltage to the ESS.
Note:
Maintenance of ESS should be performed by qualified
electrical technicians, and only after all AC and DC
power are completely disconnected from ESS.
 ESS must be disconnected from the utility and make sure that there is no accidental connection
with the utility. The PV array must also be disconnected with ESS.
Note:
As ESS has a built-in high voltage capacitor, fatal high
voltage remains in the inverter for some time after it is
shut down.
 After the ESS is shut down and the utility and the PV array are disconnected from ESS, please
wait for the internal capacitor to discharge before opening the unit for maintenance.
