Frequently Asked Questions
What is the main advantage of a low-frequency inverter like the GPSW-II?
The GPSW-II uses a toroidal transformer which provides higher peak power capacity and better durability compared to high-frequency inverters, making it ideal for heavy inductive loads.
How fast does the unit switch to battery power during a blackout?
The automatic transfer time is less than 10 milliseconds, which is fast enough to keep most sensitive electronics and computers running without interruption.
Does this unit include a built-in solar charge controller?
No, the GPSW-II is a standalone sine wave inverter with an AC charger. It can be integrated into a solar system, but an external solar charge controller is required.
Can I adjust the charging current for different battery sizes?
Yes, the charging current is adjustable up to 30A (C0-C6 settings) via the LCD monitor to match your specific battery bank requirements.
What working modes are supported?
It supports three main modes: Grid Priority (UPS mode), Battery/Solar Priority, and Power Saver mode (detects load every 10ms).
Is the output compatible with sensitive home appliances?
Absolutely. The pure sine wave output ensures that even the most sensitive appliances, such as refrigerators, motors, and medical equipment, run smoothly and safely.
