I have been put forth with this question many times in this blog, how do we add a changeover selector switch for automatically toggling of an inverter when AC mains is present and vice versa. And also the system must enable automatic switching of the battery charger such that when AC mains is present the […]

Grid Mains to Generator Changeover Relay Circuit
In this post I have explained a simple configuration which can be used as a automatic changeover circuit for switching AC grid mains to generator mains, during power failures or outages. The explained circuit will effectively switch the connected appliances to the generator mains during power failure however it won’t be able to switch start the generator automatically, […]
Petrol to LPG ATS Circuit using Solenoid Changeover Valve
In this post I have explained a simple mains to generator automatic transfer switch (ATS) which features an initial petrol start which switches to an LPG gas supply via fuel valve changeover switches. The idea was requested by Mr. Junaid. Technical Specifications sir i want to make my generator automatic start on petrol then shift […]
Solid-State Inverter/Mains AC Changeover Circuits Using Triacs
In this post I have explained 2 simple concepts for making solid-state triac based Inverter/mains AC changeover circuit, the idea was requested by Music girl. Technical Specifications I would like to replace the SPDT relay with 2 scr’s. Would you consider a circuit to replace those changeover relays? I believe a relay would need to […]
3 Simple Solar Panel/Mains Changeover Circuits
The discussed automatic change over relay circuit was requested by Mr.Karimulla Baig. The circuit normally charges the connected battery at constant current through the power received from the solar panel, and reverts to DC power from an AC/DC adapter in the absence of solar energy (during night time). Let’s the read the request in more details: Technical […]
Generator/UPS/Battery Relay Changeover Circuit
In this article I have explained a generator/UPS/Battery relay changeover circuit for implementing a customized optimization for a generator, UPS, battery power network, in order to enhance the operational efficiency of the system. The idea was requested by Mr. Sidingilizwe. Circuit Objectives and Requirements First of all thank you for adding me to your circles. […]
