Solar Battery Charger

- MPPT Solar Charging
- Dual 12V Battery Support
- OpenRTOS Firmware
- Up to 115W Output
Overview
A Nuvation Engineering client wanted to enhance the solar energy harvesting capabilities of their remotely-installed smart meter relays. The enhancement was required because existing relay installations were in locations with limited access to power so they did not collect enough energy for sustained year-round operation. Nuvation Engineering’s power electronics design team created an MPPT (Maximum Power Point Tracking) solar battery charger for the data relays, which allowed the client to sustain operations throughout the entire year.
