The total current is 6A - not 7. 5A average, not 9A, but 6A limited by the weaker panel. For parallel wiring, mixing different panels is more forgiving (different voltages cause some mismatch but less severe losses).
This comprehensive guide will walk you through the exact steps to safely connect solar panels to battery systems, covering everything from essential equipment selection to advanced troubleshooting techniques.
