AFCI (Arc Fault Circuit Interrupter) is a kind of circuit protection device, the main
function is to prevent the fire caused by fault arc.The electrical insulation aging,
breakage, loose connection, air breakdown caused by air humidity and so on, all of these
may cause an electric spark,which is called arc.
The AFCI function of the MAX series inverter is optional, and the detection equipment is
assembled inside the inverter. When an arc-drawing condition is detected on the PV
input side, the arc current could be detected by the CT assembled on the PV input-side
wire. Then the inverter will shut down. Meanwhile, the inverter will display the
corresponding fault message and the buzzer will sound, which could help to avoid harm
and economic loss to the user.
The full name of PID is Potential Induced Degradation. Since the PID effect, a large
amount of charge could accumulate on the surface of the photovoltaic module, which
makes the surface passivation of the module worse. Eventually, the fill factor, open-
circuit voltage, and short-circuit current of the module are reduced, and the power of the
photovoltaic module is attenuated.
The Anti-PID function uses the principle of reversible PID changes. MAX series inverters
rectify AC voltage at night and boost it to generate a DC voltage. The DC voltage is
connected to PV + and the ground respectively. When add a positive bias voltage to the
module to make the PID effect reverse,the Anti-PID function could repair the
photovoltaic modules at night and prolong the service life of photovoltaic modules.
NOTE: Anti-PID function is optional.
NOTE: AFCI function is optional.

According to the relevant provisions of IEC 61643-32 "Connecting to photovoltaic
devices surge protectors - selection and use of guidelines", whether for household or
outdoor photovoltaic power plants, it is necessary to ensure the implementation of
lightning protection measures for photovoltaic systems:
Fig 6.11
1）It is generally recommended to install lightning protection devices (such as lightning
rods / lightning protection belts and down conductors) to prevent lightning from hitting
the PV array.
2）Lightning protection devices and down-conductors and related equipment in
photovoltaic systems (including photovoltaic panels, inverters, cables, power
distribution equipment) should maintain a safe separation distance S.
Suggested value of S: According to the general 5 storey height (about 15m) building
roof, S takes 2.5m enough, this distance can be simplified according to the inverse
relationship of the floor height.
A. When the safety distance S is satisfied:
The position of the figure should be equipped with a lightning protection module. In
general, it is recommended to install Type II in position and Type I in position .
B. When the safety and safety distance S is not met:
In addition to position 3, Type I lightning protection module should be installed in Figure
.
3）
4）About the above lightning protection lightning receptor system related design
reference GB/T 21714.3-2015.
①③
① ③
①②④
The lightning down conductor and the equipment ground wire eventually sink at a
total ground point, but the two cannot share the wire. That is, the equipment grounding
wire should be pulled separately, and the wire diameter requirement >6mm² when the
safety interval distance S is satisfied.

6.4 Connecting The Ground Cables
In this solar system all the unloaded metal components and cases should be connected
to the ground.
Single inverter need grounding over a PE point, multiple inverters need connect all the
inverter PE cable and solar panels shelves to the same grounding point to achieve
equipotential.
The grounding steps as following:
Take out the ground screw at the inverter bottom, connect the ground cables as
following figure.
Notice: 1.The machine is safely separated from the lightning protection and the distance
is as far as possible.
2.Do not expose Grounding terminal in the air and precaution for the rain.
3.When you lock the case ground screw, the torque force should be 60kgf·cm.

7.1.1 Set inverter address
7.1.1.1 Set RS485 address with Shinebus
•If the inverter is stored over one month, its default time and date may
looks wrong, the time and date should be reset before connection to the
grid.
After inverter is started normally, inverter address can be set via RS485/USB converting
to WIFI.When multiple inverters are connected in parallel via RS485, the inverter must
be set to a different communication address. When a single inverter communicates, the
default communication address can be used.
Note: The default communication address of the inverter is 1, which can be set to 1-254.

7.2.1 Waiting mode
7.2.2 Working mode
7.2.3 Fault mode
7.2.4 Off mode
When the DC voltage is more than 200Vdc, inverter will be powered on and enters the
"waiting" state.
At this mode, inverter will check the system parameter. If the system is normal and PV
voltage is more than 250Vdc, inverter will try to connect to the grid.
At this mode, inverter work normally,and the shows
the power delivered by the inverter to the grid.
When the DC voltage is more than 250Vdc,inverter converts the DC power generated by
the PV modules into AC power and supplies them to the grid.
When the DC voltage is lower than 250Vdc, inverter will enter into “waiting” state and
try to connect to the grid, at this status, inverter consume very small power to check the
internal system status.
Note: only when the PV modules supply enough power(voltage＞200Vdc) then the
inverter will start automatically.
Power or fault code indicator light
Inverter intelligent control system will continuously monitor and adjust system
status.When there is a fault detected, LED will show the fault message.
Note: Please refer to section 8.2 to check the fault message and take corrective measures.
When the sunlight is weak or no light, inverter will stop working automatically. When it
is off, inverter will not consume gird power or PV module. At the same time, the LED of
inverter will be turned off.
Note: When PV string DC voltage is too low(≤150Vdc), inverter will be off.
Inverter current operation status can be visually checked from LED display directly.
