Common Mistakes to Avoid
5. Overlooking Maintenance Requirements
Even 'maintenance-free' systems need occasional checks. Battery terminals corrode, connections loosen, and software updates may be needed. Build maintenance access into your design from the start.
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.
1. Buying Without Researching Compatibility
One of the most frequent errors we see is purchasing SOK for 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.
