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 600Ah Lithium Bank 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.

2. Ignoring Future Expansion

Your needs today might not be your needs next year. Many builders wish they'd bought a slightly larger system to accommodate future upgrades - like adding more appliances or extending their travel season into winter.
