Hello,
I've been searching for the "best" way to enable RSD with the Tigo Optimizers and EPO with the Sol-Ark 15k. From what I've seen, the best method seems to be using pins 15 & 16 on the Sol Ark to drive a relay at the Tigo CCA. After that, there have been two methods.
1. Relay NC connection connected to the Aux Port on the CCA - When the inverter EPO is hit, power shuts off to the 15 & 16 pins, causing the relay to go from open to closed, and effectively "pressing the RSD button" on the Tigo CCA.
2. Relay NO connection interrupting the 24v power to the CCA. When the power shuts off, the tap stops sending a signal and the modules go into RSD.
I've read that when the EPO button is pressed on the Sol-Ark, the electricity from the grid can pass through to the load. That would allow the CCA to stay operational if that button is pressed. Seems like the relay option is the safest bet but which option is best?
Thanks!
