Frequently Asked Questions

What is an off-grid solar system?

An off-grid system is not connected to the utility grid. It uses solar panels to generate electricity and batteries to store that energy for use when the sun isn't shining.

Can this system power my entire home?

Yes, depending on the chosen capacity (15KW to 30KW), these systems are designed to support typical household appliances including ACs, refrigerators, and lighting.

What is the lifespan of the GEL batteries?

The Deep Cycle GEL batteries are designed with a 20-year floating design life and can handle approximately 450 cycles at 100% Depth of Discharge (DOD).

Is the mounting system compatible with my roof?

Yes, our mounting structures are customized based on your specific installation requirements, whether for a flat roof, pitched roof, or ground installation.

Does the system include remote monitoring?

Yes, the included monitoring system supports one-click registration and allows you to track power generation and system health in real-time.

Are the solar panels resistant to extreme weather?

Our Mono 550W panels are built with high-quality materials to withstand various environmental conditions, featuring IP65+ protection for key components.
