Frequently Asked Questions (FAQ)
What is the main benefit of the low frequency toroidal transformer?
The toroidal transformer provides high efficiency (up to 95%), better voltage regulation (AVR), and the ability to handle high-impact loads compared to high-frequency alternatives.
Can I switch between solar and grid priority?
Yes, the GPSW-II series features selectable priority modes (Grid Priority or Solar/Battery Priority) which can be easily configured via the smart LCD panel.
Does this unit include a solar charge controller?
No, this specific inverter model does not have a built-in solar charge controller. It is designed as a pure inverter/charger system that works alongside external controllers.
How fast does the unit switch to battery power during a blackout?
The automatic transfer time is typically less than 10 milliseconds, ensuring a seamless power supply for computers and sensitive home electronics (UPS function).
Is the charge current adjustable for different battery sizes?
Yes, the charge current is adjustable up to 30A (C0-C6 settings), allowing you to optimize the charging speed based on your battery bank capacity.
What types of protections are built into the system?
The system includes comprehensive protection against battery over/low voltage, output overload, short circuits, and internal over-temperature.
