FAQ
Q: Can this solar switch be used with a grid-tied inverter system?
A: Primarily designed for DC load control in off-grid or DC-coupled systems, it is not typically used for AC output control from grid-tied inverters. It is ideal for managing DC circuits within a solar setup.
Q: How do I set the connect and disconnect voltage points?
A: Our standard model uses easily accessible DIP switches or a small potentiometer to adjust set points according to your battery type (e.g., Flooded, AGM, Gel). The manual provides clear reference tables.
Q: What is the difference between a solid-state solar switch and a relay-based controller?
A: Solid-state switches (using MOSFETs) have no moving parts, operate silently, switch much faster, and have a vastly longer operational lifespan than mechanical relays, which can wear out over time.
Q: Is the unit waterproof for outdoor installation?
A: Yes. With an IP65 rated enclosure, it is fully protected against dust ingress and low-pressure water jets from any direction, making it suitable for direct outdoor mounting.
Q: Do you offer different current ratings?
A: Yes. While the featured model is 100A, we have a range from 30A to 200A to suit various project scales. Contact our sales team for the full product portfolio.
