Frequently Asked Questions

Q: What battery type is compatible with this 2000W pure sine wave inverter board?

A: This inverter board is designed for 48V DC battery systems, with an operating voltage range of 39.2V to 61.3V. It is compatible with most 48V lead-acid and lithium battery banks commonly used in solar and UPS applications.

Q: Can this board function as both an inverter and a battery charger?

A: Yes. The bidirectional design allows this module to operate as a DC-to-AC inverter (converting 48V battery power to 220V AC) and as a UPS charger (converting AC mains power to charge your 48V battery bank), making it a complete power management solution in one board.

Q: Is this inverter board suitable for powering sensitive electronics?

A: Absolutely. The pure sine wave output is clean and stable, making it safe and compatible with sensitive devices such as computers, audio equipment, medical devices, and variable-speed motors — unlike modified sine wave inverters which can cause interference or damage.

Q: What is the peak power output of this 2000W inverter board?

A: While the rated continuous power is 2000W, this board can handle peak surge loads of up to 4000W, which is useful for starting motors, compressors, or other high-inrush devices.
