3.4 AC Input / Output Connection
CAUTION! Before connecting to the AC input power source, install a separate AC breaker (recommended 40A) between the inverter and the AC input source for safety and overcurrent protection.
CAUTION! Do NOT mis-connect input and output connectors. There are three terminal blocks: 'AC IN', 'AC OUT1', 'AC OUT2'.
CAUTION! Ensure correct AC cable polarity (L and N wires). Reversed connections can cause utility short-circuits in parallel operation.
WARNING! All wiring must be performed by qualified personnel.
WARNING! Use appropriate cable sizes for AC input/output connections to ensure system safety and efficient operation.
Recommended Cable Sizes:
| Connection | Gauge | Cable (mm²) |
|---|---|---|

- Insert AC input cables into terminal blocks according to polarities (PE: yellow-green, L: brown/black, N: blue) and tighten screws. Connect PE protective cable first.
- Ensure cables are securely connected.
AC Output (OUT1/OUT2) Connection: Follow the same steps as AC input connection for L (LINE) and N (Neutral) cables.
CAUTION! Appliances like air conditioners require a 2-3 minute restart delay to balance refrigerant gas. If a power shortage occurs and recovers quickly, it can damage connected appliances. Check if your air conditioner has a time-delay function. Otherwise, the inverter may trigger an overload fault.
3.5 PV Connection
CAUTION! Install a separate DC circuit breaker between the inverter and PV modules.
WARNING! Do not ground positive or negative terminals of PV modules, as this can severely damage the inverter.
WARNING! Exposure to sunlight can generate lethal high voltages in photovoltaic strings. Adhere to safety precautions in photovoltaic string documents.
WARNING! Connect PV terminals to corresponding ports on the inverter. Reversing polarity can damage the inverter.
WARNING! All wiring must be performed by qualified personnel.
WARNING! Use appropriate cable for PV module connection. Recommended cable size: 10AWG (5.26 mm²).
PV Module Selection Parameters:

6.3 General Troubleshooting
Problem: LED screen display fault code 5 (Over temperature)
- What to do: Check if the fan is connected or if there are loose wiring issues. If the fan is not connected for more than 5 minutes, the machine will report fault code 5.
Problem: LED screen display fault code 12 (Inverter short circuit)
- What to do: 1. Check for a short circuit at the output terminals (e.g., a screw piercing through and causing an L-N short circuit). 2. Verify if the inverter voltage and current meet the triggering conditions.
Problem: LED screen display fault code 58 (Fan malfunction)
- What to do: 1. Check if the fan is connected properly or if there are any loose connections. 2. If the fan is properly connected: a) Check for issues with the fan detection circuit (often due to excessive soldering under the control board socket). b) Check if the fan itself is damaged.
Problem: Unable to start (Battery)
- What to do: 1. Check if the battery voltage sampling is functioning properly and if the battery voltage has been calibrated. 2. Use a multimeter to measure the voltage at the battery terminals (using a DC power supply or a real battery) to see if it reaches the minimum voltage of 11.5V per cell for startup. Note: It is crucial to configure the battery voltage according to the machine model. Connecting the wrong battery voltage can cause capacitor explosion.
Problem: Unable to start (Utility power)
- What to do: 1. Check for any short circuits at the mains terminal (e.g., a screw piercing through and causing a short circuit between live and neutral). 2. Check for any wiring errors, such as mistakenly connecting the mains input to the output terminals.
Problem: Unable to start (PV)
- What to do: 1. Check if the PV input voltage is too close to the critical threshold. 2. For low voltage versions, check if the software version numbers of the main control are compatible. If they differ significantly, the machine may not activate.
Problem: PV not charging
- What to do: Connecting the wrong battery voltage can result in damage to the auxiliary power supply on the PV side, causing a loss of power and inability to communicate with the main control.
