    How can I use an on-grid solar inverter in an off-grid setup using a pure sine wave inverter as a simulated grid?

    I have a solar system with an on-grid (grid-tie) inverter, which only works when there is an active grid supply. Unfortunately, I live in an area where there's no grid power for most of the day, so my solar setup goes unused during that time. Buying a new hybrid inverter is quite expensive and...

    How to detect actuator feedback voltage using Arduino/esp32?

    As per supplier of this valve feedback voltage will be either 0 or 24v i.e. no intermediate value,in case valv at mid then both will show 0v

    Lora module in weatherproof box and antenna outside.

    Can't we use coaxial cable and keep anteanna outside like what we do for 4G and WIFI network? Aslo can we built antenna to get at least 2km range. I have to control one relay which is 2km away from my home.
