Product Q&A

Q:How to choose between 12V and 24V inverters? What's the difference?

12V inverters are suitable for small vehicles, RVs, paired with 12V batteries. 24V inverters are better for trucks, large equipment or high-power applications, with lower current, less loss and more stable operation.

Q:Can the inverter power multiple devices at the same time?

Yes, but the total power of all connected devices must not exceed the inverter's continuous power rating. The peak startup power of appliances must also be within the inverter's peak power capacity, otherwise protection will be triggered.

Q:My device's power matches the inverter rating, why won't it start?

Inductive loads (fridges, ACs, pumps) have startup peaks 3-5 times their rated power. Choose an inverter rated 2-3 times the device's power for optimal performance.

Q:Is it normal for the fan to run all the time?

Yes. The smart cooling fan auto-starts/stops based on temperature. Higher load/ambient temps increase fan activity, ensuring proper cooling and longer service life.

Q:What is the warranty period? How to handle issues?

Enjoy a 2-year full warranty. We offer free repairs/replacements for non-human quality issues. Contact our after-sales team anytime; we'll respond within 24 hours.
