Own the whole stack
Hardware, firmware and software designed together, so nothing falls between the cracks.
About us
Engineers who build what they install.
Green Energy Systems is a Sri Lankan engineering company working where software, hardware and power electronics meet. We design our own controllers and IoT devices, write the firmware and cloud software, and commission every site ourselves.
That means one team answers for the whole system — from the inverter terminal to the CEBAssist link — and problems get solved, not passed between vendors.
How we work
Grid-first engineering
Every product is built around the rules and realities of the Sri Lankan grid.
Local, accountable support
Engineers who answer the phone, know your site, and can be there the same week.
