SCE posted the data from yesterday. My estimate was very close. Here is the graph. You can see my only consumption was the 600 watt hours in the 8 pm hour when we tested the EV charging. I easily offset all of it in the 4 pm hour and netting almost 15 KWHs of export still. Obviously, I would...

We did a little experiment today. When my brother got home from work, he brought over his Bolt EV and his Charge Point Level 2 EVSE. I wired up a plug for it and we set it to charge. Only issue is, he didn't have the App setup for the EVSE so it was set to 30 amps. With only my one XW-Pro, I...

The last few days have been excellent production, but I have nowhere to send all the power. The Victron is going into float about 1 pm and throwing away half it's possible production. Here is the battery voltage graph from the XW so far today. It's kind of hot today with intense sun, so I am...

Here is a screen cap of the page I did it as a thumbnail, I think when you click it you will then get full res.

I think you are onto something here. It sure would be nice if the system would log when these actions happen. Then we would know which one caused it. The other thing on this page "Freq-Watt P(f) Droop" that is a bit scary to me is the "Ramp Rate Increment" at 33% per second. I slowed that to...

The additional problem is that you can't tell if/when you have enough solar coming in to switch the Powerwall back on. The AC coupled solar is dead, no matter how much sun there is, until the Powerwall is producing a good local grid for over 5 minutes from the remaining battery power. My...

Sorry for this fairly long post, but I have given my similar situation some thought. The issue here is called "Dark Start" and it is a problem with all AC coupled systems. In my case, I have a Schneider XW-Pro instead of a Powerwall, but it suffers a similar issue. The best way to deal with it...

If you only connected L1 and L2 with no neutral, I would expect the XW-Pro would never qualify the input as good power and it would leave the input contactor open, the neutral connected to the transformer center tap, and it would stay running off grid. And in that case, it would not be able to...

Yes to both. This function is required in the way the XW series operates to allow both on and off grid operation without fighting the neutral balance. No matter how the system is operating, only a single Neutral / Ground bond is required and there should never be a second one and there is no...

The way the relays in the XW+ and XW-Pro appear to be the same. There is no setting to change how it controls the relays, other than some timing settings when using multiple units and/or and external contactor. The contacts that are open or closed in each operating mode are always the same. The...

I only have a single XW-Pro running as "Split Phase Master" but the idea is not that different. All of my neutrals tie back to my main grid panel, if I am running on or off grid. And the neutral bar in my main panel is directly bonded to ground at all times. The transformer in the XW-Pro has a...

Today was productive. The battery was fully charged before noon and the house was running totally off of the Enphase system. So I took the opportunity to shut down the XW and finally move the DC wiring into the new breaker panel. The box filled up. I had to bend the terminals going into the...

I looked at the other thread. A while back I did the same math and figured it would not fail in a bad way, but the batteries from the 2 banks will not share the current. It was noted in the other thread, so I will just keep my comment short here. During discharge, the NMC cells will provide...

Are you going to swap from the NMC cells to LFP? I could not find a voltage range to make them work well together.

I got 2 pics from the outside which sort of show the way it sticks through. The inside pics didn't show anything. It comes with that bracket system with the legs against the wall, but it really needs a thicker wall, I have it on the setting for the thinnest wall and it just made it. I had to...
