WARNING:
Ensure all AC power sources and loads are disconnected before wiring the unit.
4. Insert the AC output wires according to labeling on the terminal block and tighten terminal screws. Be sure
5. Make sure the wires are securely connected, and use required cord grips or conduit.
PV Connection
CAUTION:
Before connecting to PV modules/strings, install
separate
DC circuit breakers or a means of
disconnect paired with properly sized fuses between inverter and PV modules/strings. DO NOT work with or
connect live PV conductors to the unit EVER. Ensure all exposed conductors are safely disconnected from the
power source.
NOTE: Use 600V/30A rated circuit breakers. DC rated breakers must be used. The over voltage category of the
PV input is II. Please Follow the steps below to complete PV connections.
WARNING!
All wiring must be performed by qualified personnel.
WARNING:
Making connections with live a PV source will damage the inverter!
WARNING!
It's very important for system safety and efficient operation to use appropriate cables for PV
module connection. To reduce risk of injury, use the proper recommended cable size below.
CAUTION:
Appliances with heavy start and run demands, such as air conditioners, require special
consideration. For many air conditioners for example, at least 2~3 minutes to restart might be required to
allow enough time to balance refrigerant gases. If a power outage occurs and recovers in a short time, it may
cause damage to the connected appliances. To prevent damage, please check with the manufacturer of the
appliance to see if it is equipped with a time-delay function or soft-start feature before installation. Overload of
the inverter/charger may trigger a fault leading to a sudden loss of AC output power, which may cause
damage to appliances with motors/compressors.
CAUTION: Important
Connect AC wire to correct terminals. If either Line 1 or 2 are reversed with Ground/Neutral it will cause a
short-circuit and damage the equipment and loads connected to the system.
