<br>
I have a client with a sol ark and it doesn’t have warm up or cool down, kind of amazing companies are going backwards in their tech. <br>
<br>
<br>
Has anyone come up with external fix for this?<br>
<br>
I am guessing the internal relay on the sol ark switches closed when it sees the correct volts/hz and opens the sol ark relay when it sends the off signal.<br>
<br>
If thats correct I can pretty easily use a delay relay on the off cycle assuming the on signal has a time window to allow for this delay in sending power to the inverter. <br>
<br>
The on delay I don’t see anyway unless I use a contactor with on delay relay.<br>
<br>
Maybe there is a off the shelf generator transfer switch that has this built in?<br>
<br>
Thanks in advance<br>
<br>
