Design guidance and custom diagrams

First we discuss your specific energy needs and expectations. Then we determine the appropriate size battery bank, solar array, and other aspects of the system -- additional charge sources, sensors & monitoring/control equipment.

These first couple steps are included at no charge with our preliminary system design service. Start with the Trek Energy Audit Calculator to determine system sizing.

Custom wiring diagrams are available by request and include the following:

- all primary components and how these fit together (batteries, inverters, chargers, monitoring and control, etc.)
- appropriate wire size and circuit protection for every circuit
- any other accessories or important details

Energy upgrades have never been easier with the help of our custom wiring diagrams and design services. Take guesswork out of the equation and ensure your off grid electrical system is safe, efficient, and fully functional.

Seeking a professional installation? We work with a nationwide network of trained and certified specialists.

Note: Custom wiring diagrams are currently only available for systems we design from the ground up.
