Firmware, converter design and product validation for industry
I take a product problem from the bench to a tested, documented result. Industry work is routed through NMIT where required.
Case study
Solar charge controller firmware for Aviva Smart Solutions
- Client
- Aviva Smart Solutions Pvt. Ltd., Bengaluru
- Role
- Principal Consultant
- Period
- May–October 2026
- Product
- Solar buck charge controller
The problem
The existing charge controller tripped on high current, and its original firmware was not available. The company needed MPPT firmware that limits charging current to the battery's setting, whatever the size of the PV array.
What I did
- Identified the board's sensing, PWM, relay and display behaviour by testing
- Diagnosed the earlier firmware's high-current trips
- Developed MPPT with load curtailment and a battery-charging algorithm, in controlled, documented steps
- Ran structured bench tests on a programmable PV array simulator
Delivered
A test report and a firmware build for field evaluation.
“We appreciate your technical depth, methodical approach, and prompt responsiveness throughout the engagement.”
