The flexible open source Electronic Load Controller / Induction Generator Controller for hydro power

In remembrance of Rev. Gerhard Schuler, who pioneered micro hydro power in Papua New Guinea.
Warning for self-builders 
A ELC, which fails because it is built badly, can destroy the whole hydro system and all user appliances.
Wrong wiring can expose users to mains voltage - danger to life.
If you don't have experience with building electric equipment, I would not recommend to build your own ELC. You will need to find a qualified engineer who does it for you, or teaches you how to. Safety information


Feedback wanted - is a cheaper PCB relevant for you?

Work steps



Either buy the pcb from me or get one made.

Circuit diagram: Schematic

Kicad Files and gerber files are available from me. My PCBs are made at elecrow.


Source and buy all the parts. Parts list Parts depend on the options you need.


Solder the PCB connectors (through hole technology)

Build and wire

Wiring. Good cooling for the SSRs and Triacs is absolutely important.

Configure, Calibrate, Test

Manual Configure the software parameters.
Calibrate the measuring inputs. Thoroughly test all the functions
