i just asking for the logic or the simmilar program. i build an ATS for switching between batteries and grid. I want when the battery drain it switch to grid and charge untill it full. When the battery full i want to switch it untill it drain. and so on. i used my logic and it keep switching between the line.
i used my logic and it keep switching between the line.
What logic would that be ?
It sounds like you need to introduce some hysteresis between the on and off levels to create a deadband to prevent the system hunting between the 2 power sources
if battery voltage < trigger level switch to grid start charging battery else if battery voltage > trigger level + deadband value switch to battery stop charging battery end if
Welcome to the forum.
Please read the post at the start of any forum , entitled "How to use this Forum".
Then look down to "code problems" about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.
- What are your batteries?
- What voltage and capacity are your batteries?
- What are you using to charge the batteries?
- How do you detect battery voltage?
- How do you detect that the mains power is ON?
Can you please post a complete copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
