FAQ

  • Can solar panels with different orientations be connected to an off-grid system?

    Yes, but they must be connected to separate MPPT (Maximum Power Point Tracking) channels. Panels on the same MPPT channel should have consistent orientation, tilt angle, and quantity to avoid mismatch losses.

  • Can the solar module power exceed the inverter's rated power during system design?

    Yes, appropriate overloading is allowed. The purpose is to enable the inverter to operate at full load even under average light conditions, thereby improving equipment utilization. The overloading ratio must be calculated based on local solar radiation conditions and module degradation rates.

  • How to Implement Lightning Protection for Off-Grid Systems?

    A comprehensive approach is required, covering both direct lightning strikes (using air terminals, down conductors, and grounding devices) and induced lightning surges (installing SPDs and equipotential bonding). Specific measures must comply with relevant lightning protection technical standards.
