WARNING: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
CAUTION!! Do not place anything between the flat part of the inverter terminal. Overheating
may occur.
CAUTION!! Do not apply anti-oxidant substance on the terminals before terminals are
connected tightly.
CAUTION!! Before making the final DC connection or closing DC breaker/disconnector, be sure
positive (+) is connected to positive (+) and negative (-) is connected to negative (-).
AC Input/Output Connection

Before
connecting
to
AC
input
power
source,
please
install
a
separate
AC
breaker
between
inverter
and
AC
input

Please follow below steps to implement AC input/output connection:
1.
Before making AC input/output connection, be sure to open DC protector or disconnecter FIRST.
2.
Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral conductor N 3 mm.
3.
Insert AC input wires according to polarities indicated on terminal block and tighten the terminal
screws. Be sure to connect PE protective conductor ( ) first.
→Ground (Green) L→LINE (Black) N→Neutral (White)
WARNING:
Be sure that AC power source is disconnected before attempting to hardwire it to the unit.
4.
Then, insert AC output wires according to polarities indicated on terminal block and tighten terminal
screws. Be sure to connect PE protective conductor ( ) first.
→Ground (Green)
L→LINE (Black)
N→Neutral (White)
Important to Note:
When the inverter is working in PV mode, battery mode, or standby mode, the output neutral
is connected to the ground of AC output (neutral/ground bonded).
When the inverter is working in AC mode, neutral of output is disconnected to grounding of AC
output and connected to neural of AC input.
5.
Make sure the wires are securely connected.
CAUTION: Important
Be sure to connect AC wires with correct polarity. If L and N wires are reversed, it may cause a
utility short-circuit when these inverters are in parallel operation.
CAUTION: Appliances such as air conditioners require at least 2~3 minutes to restart because to have
enough time to balance the refrigerant gas. If a power outage occurs and recovers in a short time, it
may cause damage to your connected appliances. To prevent this damage, please check the appliance
manufacturer for time-delay start function before installation. The inverter/charger will trigger an overload
fault and cut off the output to protect your appliance which may cause internal damage to the appliance.

power all connected loads, battery
energy will supply power to the
loads at the same time.
Utility provides power to the loads
only when battery voltage drops to
either low-level warning voltage or
the setting point in program 12.
SUB priority
Solar energy is charged first and
then power to the loads.
If solar energy is not sufficient to
power all connected loads, utility
energy will supply power to the
loads at the same time.
