Product Q&A

Q:How to choose a suitable inverter?

For resistive loads like bulbs, a modified wave inverter is suitable. For inductive or capacitive loads such as fans, air conditioners, or computers, a pure sine wave inverter is recommended to ensure load life and quality power.

Q:How do I choose the size of the inverter?

Select based on load power: Resistive loads require equal power; Capacitive loads need 2-5 times the load power; Inductive loads need 4-7 times the load power.

Q:How to connect batteries to the inverter?

Keep cables short (less than 0.5m for standard cables) and match polarity. For longer distances, contact us for cable size calculations to avoid voltage drops and under-voltage alarms.

Q:How to calculate battery size for working hours?

Use the formula: Work hours = (Battery Capacity * Battery Voltage * 0.8) / Load Power. Note that this is a reference value and may vary based on battery condition.

Q:What is the warranty period?

The product comes with a 1-year warranty.
