 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |
Forum Index : Electronics : Timer/voltage sensitive relay with arduino

I don't know anything about coding, but am wondering if it is possible to use an arduino to replace what I now use a timer and voltage sensitive relay for. At the moment I use a timer with inbuilt relay to turn my inverter on in the morning and off in the afternoon so the GTI inverters can back feed when the sun gets on the panels. I also use a Voltage sensitive relay set to turn the GTI inverters off when the batteries are fully charged. At the moment I turn the GTI inverters off when the batteries are 28.8 volts and then they come back on when the battery voltage falls to 26 volts. Just wondering if it would be possible to use an arduino to do this job and also to switch a solid state relay or Mosfet so I can do away with the mechanical relays. Does anyone know if this is feasible or worth the trouble doing? cheers Pete |

It is feasible but if you don't have much coding experience Arduino C++ can be steep learning curve. Young minds can manage it readily enough but I have abandoned it. All versions BASIC are far easier to learn and for your application maximum execution speed isn't needed. So an interpreted version such as MMBasic is easier still as no compiler is needed. MMBasic has a built in editor so the program can be written end modified in the chip with just a terminal program. A PicoMite (a R Pi Pico with MMBasic firmware) would be my choice. Its very cheap, firmware loading is just drag-n-drop to its USB port which then becomes its serial console port. The TBS Microcontrollers forum is largely PicoMite so you can get plenty of help there. Firmware and manual here https://geoffg.net/picomite.html Edited 2025-06-27 18:42 by phil99 |
