2.2 Wiring specifications and circuit breaker selection
Wiring and installation methods must comply with national and local electrical code
requirements.
Recommended PV array wiring specifications and circuit breaker selection: The output current
of PV array is affected by the type of PV modules, connection method and lighting angle, so
the minimum line diameter of the PV array is calculated according to the short-circuit current
of the PV array; please refer to the PV module specifications for the short-circuit current value
(short-circuit current does not change when is unchanged when the PV modules are in series;
when they are connected in parallel, the short-circuit current is the sum of the short-circuit
current of all parallel modules); the short-circuit current of the PV array shall not exceed the PV
maximum input current.

Note: The voltage must not exceed the maximum PV input open circuit voltage of 145V
when connected in series.

Note: The wiring diameter is for reference only. If the distance between the PV array and the
all-in-one machine or between the all-in-one machine and the battery is long, using athicker
wire will reduce the voltage drop and improve system performance.
Note: The above wiring diameters and circuit breakers are only for recommendation. Please
select the appropriate wiring diameters and circuit breakers according to the actual situation.
2.3 Installation and wiring
Installation steps:
Step 1: Determine the installation location and heat dissipation space: determine the
installation location of the all-in-one machine, such as the wall; when installing the all-in-one
machine, ensure that there is sufficient air flow through the all-in-one machines heat sink,
leaving at least 200mm space between the left and right air outlets of the all-in-one machine to
ensure natural convection heat dissipation. Refer to the complete machine installation diagram
below.
Warning: danger of explosion! Never install the all-in-one machine and alead-acid liquid
battery in the same airtight space! Also dont install it in aconfined area where battery gas may
collect.

Step 2: Remove the terminal protection cover

Step 6: Start the all-in-one machine
First of all, close the circuit breaker at the battery end; secondly, turn the
rocker switch on the left side of the machine to the ON state, and AC/INV
indicator flashing means that the inverter is working normally; then, close the
circuit breaker of the PV array and mains power; finally, turn on the AC loads
one by one after the AC output is normal, so as to avoid protection action due to
large instantaneous impact generated by turning on the loads at the same time.
At this point, the machine can work normally according to the set mode.
Note: To power different AC loads, it is recommended to turn on the loads
with large surge current first, and turn on the load with small surge current
after the loads are operating stably.
Note: If the machine does not work properly or if the LCD or indicator
displays abnormally, refer to Section 6for troubleshooting.
