Energy harvesters

SolGate is a unique product at the international market set of autonomous power supplies for IoT devices

General problem

SolGate solves 3 main tasks for wireless IoT power supply:

  • generation (harvesting) of required energy;
  • measurements support and parameter processing by sensors and transducers;
  • wireless transmission of gathered information.

All tasks were optimized in an integrated manner to secure viable solutions

The function of system engineering design is to balance the assembled energy with the energy needs

Some question

How does solar and thermal works

Using a small solar cell and Peltier module as an energy source our product can provide full autonomy to any IoT device.

The temperature difference between the solar cell and the environment in working mode can reach 40 degrees. Thermal element converts this temperature difference into additional electrical energy.

It helps obtaining 90% more energy in the any season.

SolGate Mobi

IoT device from old smartphone


  • 70% of IoT devices need autonomous power
  • a lot of unused energy around us: light, heat, GSM, wi-fi
  • a lot of disused smartphones that satisfy all the technologies of energy reception and signal transmission


Decision ways of these 3 problems lead to a unified solution: to use old communication tools - smartphones as energy absorbents for autonomous power supply of IoT sensors.


  • switch off the smartphone display and other non-core peripheral devices and functions
  • supplement the system with a solar cell and a charge controller
  • provide a usb-/inner socket for sensor power supply


  • use of ready-made devices in IoT power system
  • re-use of hundreds of millions of old smartphones
  • providing a reliable power source with a combined charging method (solar + RF) for IoT devices

Install your new (old) helper on the principle "once installed and forgot"

Now you can:

  • open the door when your cat comes back home
  • send to yourself the photo inside of your fridge, when you go shopping
  • control height of the lawn and cucumbers length every day

Send to us your case, make a video and we will return your money back for SolGate mobile kit!
