ESS programming

Easy Solar II, Smart Shunt, off grid.


I would like to program ESII, so that the loads on "critical loads output =AC OUT 2" would be activated by SOC.

So the critical load output would be activated when the state of charge is 100% and deactivated when it reaches 50%.


How can i do that?

OK, AC2 is non-critical loads.

I think what you want to use is the programmable relay assistant.

and turn off

Pretty much, yes. Just test the conditions you set properly.

ESS isn't for use off-grid and doesn't seem like the right idea for what you want to do.

You could probably use one of the other assistants to control the relay based on SOC but that's beyond my comfort zone.

@JJ-O-JJ

@nickdb is correct ESS will not suit your needs.

By critical do you mean loads you dont want turned off?

If not connect it to AC 2 out and program that relay to switch on and off.

Or

The entrie system can be programmed to switch on and off based on SOC in the inverter tab.

You probably need to use NodeRED and the Venus large install for this kinda customisation.

System relays can't be changed via node red, unfortunately
