Product Q&A

Q:Q1: What kind of loads can this low frequency pure sine wave inverter drive?

A1: It can support various household and industrial loads, especially inductive equipment such as air conditioners, water pumps and motors, with strong resistance to instantaneous impulse loads.

Q:Q2: Does this inverter support solar charging function?

A2: Yes, built-in PWM or MPPT solar charge controllers are optional. MPPT version raises solar charging efficiency by 15%-30% compared with PWM model.

Q:Q3: What battery voltage options are available for this series inverter?

A3: We provide 12V, 24V, 48V and 96V DC battery versions to match different power models ranging from 700W to 7000W.

Q:Q4: What working environments is this inverter suitable for?

A4: It is specially designed for off-grid and unstable weak grid areas, widely used in rural homes, farms, construction sites, remote islands and commercial backup power systems.

Q:Q5: What are the advantages of low frequency inverter compared with high frequency models?

A5: Equipped with built-in heavy-duty isolation transformer, it features higher stability, stronger load adaptability and longer service life, though it has larger size and heavier weight.
