 Repair and Maintenance
ESS should be repaired by trained electrical technicians only.
 PV Array
When installing and configuring the PV array, make sure that the PV array's rated voltage
parameters which provided by the manufacturer could meet the applicable specifications. Make
sure the open-circuit voltage of the PV array under intensive sun, with ambient temperature of
-13°F (-25°C), does not exceed maximum withstanding voltage of EnerSolis (500Vdc). Voltage
exceeding 500Vdc will cause permanent damage to ESS.
 Grid Connection
Only the distributor whom has a licensed electrical engineer can install the PV inverter. To
install and operate to the grid require the permission from the local power company. Please contact
your local distributor for installation details.
