3.4 Working Principle

The MAX-X series inverter works as follows:

1>The PV panels gather solar to generate DC power to inverter.

2>With input current detection circuit, it can monitor all the PV panels' working status

and use MPPT to track the maximum power point.

3>With inverter circuit change DC power to AC power, and feed power back to grid per grid requirement.

4>With output isolation relay can isolate AC output and grid, if anything goes wrong on either inverter side or grid side, isolation relay can disconnect inverter immediately.

3.5 Inverter Storage

1>Do not unpack the inverter and store it in a ventilation dry place.

2>Keep the storage temperature at -30 °C- +60°C and humidity at 0-95%.

3>A maximum of three inverters with package can be stacked.

4>If the inverter has been long-term stored, inspections and tests should be conducted by qualified personnel before it is put into use.

After being stored for a month or longer, the inverter's time and date could be wrong, you need set the time and date before using, for more details please refer to Chapter 7.1 inverter commissioning.

3.6 Grid Types

The MAX-X series, MAX100-133KTL3-X LV inverters connect to the grid like following drawing 3.5, MAX 125-150KTL3-X MV inverters connect to the grid like following drawing 3.6.

3.7 AFCI Detection Function

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-X 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.

NOTE: AFCI function is optional.

3.8 Anti-PID Function

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-X 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.

4 Unpacking

Checking before installation

1>Before unpacking the inverter, check the outer packing materials for damage.

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 ①③ of the figure should be equipped with a lightning protection module. In general, it is recommended to install Type II in position ① and Type I in position ③. 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 ①②④.

3) 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.

4) About the above lightning protection lightning receptor system related design reference GB/T 21714.3-2015.

7.2 Operation Mode

7.2.1 Waiting mode

When the DC voltage is more than 180Vdc, 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 195Vdc, inverter will try to connect to the grid.

7.2.2 Working mode

At this mode, inverter work normally, and the Power or fault code indicator light shows the power delivered by the inverter to the grid.

When the DC voltage is more than 180Vdc, 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 180Vdc, 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>>195Vdc) then the inverter will start automatically.

7.2.3 Fault mode

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.

7.2.4 Off mode

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.

7.3 LED Display

Inverter current operation status can be visually checked from LED display directly.
