Hi,
I have a similar setup, my Delta 2 is powering internry, computers, Rpi with HA, CCTV,... You can use the Priority Solar switch (switch.delta2_prio_solar_charging) to stop the Delta 2 from getting power from the grid (when tariffs are high and battery is about x%). I have UPS that I keep between the Delta2 and devices to avoid issues and as extra protection, I had them arlready, but in theory you don't need them.
Thanks Raphaël
Thanks Raphael, your setup sounds indeed identical.
Few questions pop up;
I'm also thinking to leave my UPS in between for now. This will also allow me to use the Ecoflow for something else if I need it without my whole house going down.
Thanks!
Just to be clear:
There is a risk using a cloud integration, but in my setup, I have other integrations linked to cloud services (not my choice :-( ) so if any system is offline I will have issues.
Yes, AC is on most of the time, it is off only when I'm not using the Delta2 to keep the charge (the D2 is also used in my camper van on weekend away).
Thanks. I'm testing this now. But with prio solar charging on and charge at 98% (see screenshot and validated in app) it still seems to be passing through instead of draining from the D2.
I actually have 2 old solar panels (120W total) always connected so maybew there is something to do with the Ecoflow XT60 cable.
Mhh. That could be. Does it keep working also when the panels deliver 0 energy or does it jump to AC Pass through when the panels deliver 0?
It does not matter if there is or not solar production, at 0W it still does not take from AC.
Also, just to show you, with prio solor, AC in is at 0:
Indeed! Was just looking at the cable and it seems that they use XT60i. The i (added to XT60) seems some kind of data signal maybe that triggers it. Are you using a XT60i cable (eg the original) or a' normal' XT60 to solar cable? Think I will order the original anyway just to test.
Yes, I have an "i" version. The difference is that the amp solar input can be higher can with the car (not "i") but it might be used as well by the D2 software to block AC. Extra info: https://www.youtube.com/watch?v=T1qFCzeCKF4
Well spotted. Cable ordered. Should have it in the next few days. Wondering if it will need a resistor or anything else connected to 'fake' that there is a panel connected at the ends of the cable.
Arghh. Official cable for solar charging (the correct one for the D2 with XT60i) + even connected panel (although unfortunately no sun right now) but still no luck. Pro solar on or off; It keeps using pass through.
Do you have any other switches/settings changed? Could you maybe post a screenshot?
p.s. I also mailed Ecoflow but no response yet
Hi @tyfoon I just took these 2 shots now. What I have behind the D2 is taking just above 250W and charging is setup at 243W. Without prio solar, AC in is 521W, out 280W so ther is pass through With prio solar: AC in is a 0W, out 245W, solar in 42W (not much sun right now)
I hope it helps.

Thanks for sharing this. really appreciated. I see indeed nothing that is different from my settings although you seem to have an extra battery but I cannot imagine that plays a role.
Even tough I have a panel connected, the sun today is 0 so also 0 Watt from panel. Last thing I can try is to see if there is actual sun and current coming from the panel, it might switch something internally.
Does your solar prio switch continue it's function even if solar input is actually 0?
Yes, the fact that there is sun or not does not affect. Now, the panels are always connected, so maybe the XT60i has an impact.
Thanks for creating this integration.
Quite a lot of settings are exposed. I have a question about that;
I want to use my Delta 2 to continuously power my ‘IT environment’ which is basically router, few POE switches, few PI’s, Few Intel NUC. Overall they draw about 125w-140w continuous.
I want to charge the Delta 2 (triggered by Home Assistant) when prices are low and use the Delta 2 stored energy when prices are high + in case of power outage. In case the battery is empty it should just pass through the power from the mains.
I currently also have a UPS in between but will pull that obviously when above is up and running.
Building the automations is no issue but what setting/controls can I best use on the Delta 2 to facilitate this?
