SEC-B80-8A is a smart DC/DC designed for Maximum Power Point Tracking and battery charge applications in electric vehicles with integrated solar modules.

One of the goals of making this project open-source is to make high-end components more accessible to the many awesome teams that join for the World Solar Challenge in Australia, and even similar projects that students and companies alike venture in. With smart power conversion we hope to bring a sustainable future one step closer!

TPEE can supply assembled and tested units, or you can visit the GitHub page if you want to build one yourself.

FAQ

For items that are in stock, the delivery time is within 2 weeks. The typical lead time for products that are out of stock is around fourteen weeks. 

No, there is no minimum order quantity.

TPEE may offer discounts based on order size or as part of sponsorship deals, subject to the level of support required.

The SEC-B175-7A is designed for high-efficiency power conversion and uses Gallium Nitride transistors. It has specific voltage and current capabilities detailed in the datasheet.

TPEE uses a solar panel simulator and DC-load testing setup, as well as additional tests for extreme conditions such as high temperatures and voltage/current protection.

Yes, the output side can be paralleled. However, each solar string or panel should be connected to its own MPPT to avoid issues.

TPEE uses a combination of real-world testing data and digital modeling to estimate specifications, which are continually refined for accuracy.

Yes, the software is open-source, allowing users to adjust the MPPT algorithm or other settings. However, modifications are at the user’s risk and require specific tools for reprogramming.

Available measurements include input/output voltage, current, and temperature of certain components like MOSFETs.

The MPPT’s software supports various modes through CAN-bus. The devices can be enabled and disabled. Furthermore, telemetry data is available through the CAN bus interface.

Yes, TPEE’s MPPTs are tested for high temperatures. While cooling is often adequate with airflow, additional cooling measures can be implemented as needed.

Yes, TPEE is open to meetings to discuss technical questions, support, and potential sponsorships.
