FAQs & Support

1）The installation carrier is sturdy and can bear the weight of the inverter for a long time.

2）It is recommended that the installation ambient temperature be lower than 50°C and the ventilation should be good.

3）In order to ensure the best operation, it is necessary to avoid direct sunlight, rain and snow.

4）During operation, the case temperature will be relatively high, please do not install the inverter in a place where it is easy to touch.

5）The space around the inverter must meet the installation, maintenance and heat dissipation requirements.

Vertical installation/ Do not allow lying down/ Leaning back and inversion

1）Do a good job of line marking to reduce the probability of errors

2）Before connecting to the inverter, use a multimeter to measure the input voltage of the component on the positive and negative sides to ensure that the polarity is correct and does not exceed the maximum input voltage

3）Use special crimping tools for photovoltaic terminals

4）If conditions permit, you can use an infrared thermal imager or a spot temperature gun to confirm the connection point temperature after grid-connected power generation.

1）Tighten the cable gland

2）Idle interfaces are sealed

3）The cable entry cover is closed

4）Conduit sealing treatment

5）Confirm and lock the waterproof cap

1）Weather Reason

2） Ambient Temperature

3）Component Orientation

4）Distance Between Components

5）Component Inclination

6）Dust Shielding

7）Component mismatch

8） Component Virtual Label

9）Grid Instability

10） Inverter Reports Fault

1）Poor Wi-Fi signal

2）GPRS signal is not good

3）Home broadband arrears

4）Problems with router settings

5）Router failure

6）The router is overloaded

7）The module interface is loose

8）Mixed wiring of communication lines and power lines

9）Communication module failure

10）Inverter failure

Different models have different requirements, the specific reference is as below:

Wall Mount and Bracket Mount

1）It is recommended to connect the protective grounding and the PE terminal of the AC wiring at the same time.
2）The diameter of the protective grounding cable should be the same as that of the AC output PE cable.
3）In order to improve the anti-corrosion performance, it is recommended to apply silicone or paint on the outside of the ground terminal for protection.
4）Near-end grounding is recommended. For a system with multiple inverters connected in parallel, ensure that each grounding wire is connected to the same potential.

1） When connecting photovoltaic modules to the inverter, the Amphenol H4 photovoltaic special connector provided with the inverter should be used. Compatible models may not guarantee long-term effective contact of metal terminals.
2） When crimping the positive metal terminal, do not also crimp the limit stop bar, otherwise the metal terminal will not be stuck, resulting in “heading”
3）Strictly prevent the reverse polarity of the DC input. It is forbidden to connect the single group in series in the same MPPT. Make sure that the terminal is correct before inserting the terminal into the inverter (it is recommended to use a multimeter to measure)

1）Pay attention to the correct connection of the neutral wire polarity
2）It is forbidden to connect the load to the output terminal of the inverter without passing through the circuit breaker;
3）Each inverter needs to be equipped with an independent circuit breaker to ensure safe disconnection from the grid
4）When using multiple single-strand cables for AC output, use fireproof mud to seal the gap between the sealing ring and the cable after wiring is completed.
5）When a large number of single-phase output inverters are connected to the same low-voltage transformer in the three-phase power grid, attention should be paid to the reasonable distribution of the inverters among the three phases, and the load balance of the three phases should be maintained as much as possible to avoid the failure of a certain phase due to insufficient consumption. The phase voltage rises and damages the electrical equipment;

1）Make sure to use terminal blocks for lock wire
2）Make sure the terminals are locked
3）Do not lock the screw to the cable insulation
