Frequently Asked Questions (FAQ)

Q: Is pure sine wave really necessary for my devices?

A: For computers, servers, medical equipment, audio gear, and anything with AC motors — yes. Modified sine wave can cause buzzing, overheating, or malfunction in sensitive electronics.

Q: How long will a 100Ah battery last?

A: At 500W full load: ~1.8 hours (12V 100Ah). At typical 200W load: ~4.5 hours. LiFePO4 batteries provide more usable capacity than lead-acid.

Q: Can I leave it plugged in 24/7 like a standard UPS?

A: Yes, the unit is designed for continuous operation. It passes through grid power normally and automatically switches to battery during outages.

Q: Does it work as a solar inverter too?

A: With an external solar charge controller connected to the battery bank — yes. The unit draws from the battery which is charged by solar.
