We build the boards,
not just the boxes.

NumiTron Power Systems Ltd is a Nigerian inverter manufacturer based in Awka, Anambra State. We were registered in July 2023 and build pure sine wave inverter systems for homes, shops, offices and commercial loads — 24 V units from 2.5kVA to 5kVA, and 48 V units from 3.5kVA to 10kVA.

What sets us apart is where the engineering happens. Most solar companies in this market import finished units and resell them. We design our own control boards around the STM32G071 microcontroller, assemble them ourselves, and write the firmware that runs them — a control application ported from a field-proven design and adapted to our own hardware. When something needs fixing or improving, we change the source, not the supplier.

That ownership is also why every unit can report back. Our monitoring platform lets an owner watch output power, AC quality and battery state live, adjust the inverter's settings remotely, and switch the output on or off from anywhere — because we control the firmware that talks to it.
