How do I choose the correct model for my solar system?

Calculate based on panel voltage (e.g., 1000V/39V/1.15=22 panels per route). Divide total panels by this number to determine the required sets and poles (e.g., ERS-2, ERS-4, ERS-8). Ensure switch current exceeds panel string current.

Is the product customizable?

Yes, we accept OEM customization including voltage, rated current, connectors (Glands/Mc4/Knock Outs), string configurations, and pole counts.
