Is it possible to do grid pass thru before inverter overload without using Node Red or SSH? Perhaps using assistants? I have a Quattro 10k and a Cerbo GX.
Does ESS automatically do the same thing? I don’t want to use ESS if I can avoid it.
I can think of 4 scenarios where an overload could occur: a) surge currents - not a concern in my context b) low battery SOC - not my concern c) no or weak sun - should not normally happen as system should switch to batteries automatically d) big loads.
3d. For big loads you can have them on ac 2 out and on a certain threshold just set a power cut to those loads. Not the same as your pass through idea but would stop an overload.
The only other way is to shift the input current limit dynamically which is what ess would do.
I fully understand. I will look further into the options.
Concerning AC Out 2, I was thinking of using battery/solar, then pass through if grid is available, then cut it off entirely if necessary, using assistants. Kind of emulate what ESS does. It’s simpler to just use ESS. The complication I have is that to use ESS, I have to install a Ziehl device or equivalent which the Victron agents here do not stock and is not locally available.
However, your feedback is useful as to my options.
I assume then you are using some type of ac ignire right now then?
You could use the generator start stop on the gx wired to an aux or temp input (assistant set to disconnect primary relay) to ignore ac unless the loads gets above a certain threshold. All settable on the gx and can be tuned as you see the need.
It won’t exactly be pass through but you will have the grid to assist the higher loads. If you know your expected loads then have one set input current limit for that.
Yes. Currently just using a programmable relay assistant (no GX) but I can easily change the set up. I remember seeing a load current limit option but I didn’t set that. I will have another look.
