How should I maintain the inverter to ensure longevity?

2026-10-12

1. Keep the installation environment well-ventilated and dry; clean the cooling fan and heatsink regularly; 2. Periodically check that terminals are tight; 3. Ensure the display shows normal data; 4. Check waterproof seals for outdoor installations before rainy seasons; 5. We recommend a professional inspection every 6-12 months.

What should I do if the battery is not charging or charges slowly?

Please check: 1. Whether the PV panels are generating normally (MPPT voltage reading); 2. Whether the battery type setting is correct (lead-acid/lithium); 3. Whether the charging current limit is set too low; 4. Whether battery connections are secure; 5. Whether the battery is already full or in protection mode.

What should I do if the fan is not running or is noisy?

Inverters feature temperature-controlled automatic cooling fans that only operate when needed, running quietly most of the time. If the fan does not work at all, it may be a loose fan cable connection, a defective fan, or a PCB failure

What should I do if WiFi cannot connect or disconnects at night?

1. Confirm the WiFi is 2.4GHz band (5GHz is not supported); 2. Check that the password is correct; 3. Check whether the inverter is set to night low-power mode—if so, it will auto-recover when DC power returns the next day; 4. Restart both the router and the inverter and try again.

What should I do if the inverter shows an error code or red light?

The inverter LCD screen or mobile app will display a specific error code. Common faults include: grid over/under voltage, PV insulation fault, over-temperature, fan failure, etc. Please record the error code and troubleshoot according to the manual. If unresolved, contact technical support with the model and error code

What should I do if the inverter will not power on?

Please check: 1. Whether the battery voltage is normal (not depleted); 2. Whether the battery polarity connection is correct—never reverse positive and negative; 3. Whether the DC breaker/fuse is on or blown; 4. Whether PV input is normal. If all checks pass and it still does not power on, please contact technical support.

How long is the inverter warranty period?

The standard warranty is typically 2-5 years, and some premium grid-tie inverters can be extended to 10 years. The warranty period starts from the date of delivery. Non-human-caused defects are covered with free repair or parts replacement.
