Ensure that your fuses are appropriately sized to accommodate your inverter’s 30-second current rating multiplied by 1.25, covering both positive and negative cables, as well as your solar controller/regulator’s maximum output multiplied by 1.25. Fuses play a vital role in safeguarding cables during short circuit scenarios involving your inverter and/or solar controller/regulator. It’s imperative to use cables of the correct size for optimal performance and safety.
