Common Mistakes to Avoid

3. Focusing Only on Upfront Cost

The cheapest option often becomes the most expensive. We've seen too many builders replace budget components within months. Quality matters, especially for items that are difficult to access after the build.

1. Buying Without Researching Compatibility

One of the most frequent errors we see is purchasing SOK with Promaster without checking compatibility with existing systems. For example, mixing battery chemistries or using a charge controller that can't handle your solar panel voltage. Always verify specifications before buying.

4. Improper Installation

SOK with Promaster installed incorrectly can be dangerous. Whether it's undersized wiring, inadequate ventilation, or mounting issues, mistakes can lead to equipment failure or safety hazards. Always follow manufacturer specs or consult a professional.
