    Sorry, it must have been confusing the way I stated it. The LG RESU10H-R that plugs into the Solaredge is $5-6k for 9.8kWh. The $20k was for the Enphase battery they wanted to sell me instead, which is ALSO ~10kWh, so 4x the cost for no additional capacity. The RESU10H-R battery will handle...

    The benefit I'm looking for out of it is basically having whole house UPS in case the power cuts out, and in the case of rolling blackouts, we would have gone without any power loss at all. Plus, the Solaredge panels cut all generation when the grid goes down, so there's no benefit in the event...

    That's true, but if you're talking about backup for outages, it's hard to justify on a dollar basis anyway. Can you really not afford to be down for 10 minutes? Is the amount it costs you worth it? The answer for pretty much everyone is no. The way I started approaching this, honestly, was...

    Until you run out of gas and can't get anymore because the stations are empty and they can't get trucks to them to refill them, like we had this past time. Or more likely, forget to change the gas in them and have to get the old gas out before you can run them, if I'm honest.

    What I meant is, power from the panels must go to the house first, so it must already support unbalanced load. Otherwise, you'd send the full 240V you generate out to the grid and then get the power back from the grid, wouldn't you, letting the grid handle the load balancing? I don't know...

    From the manuals, it still needs a critical loads panel, and the switching is done automatically in the storedge. The 5 wires are the RS485 communication wires for communication. My point is that it's already designed to do all of that, it's not complicated to hook up their battery to their...

    I'm trying to understand, because I feel like I have almost all the pieces, but I just can't connect them right. What it really comes down to for me, I think is that, for the $5000-6000, the RESU10H plugs right into the Storedge, and does everything it needs to do, with the auto-switching...

    Yeah, that's the big deal is that I already have the Storedge, and already have 11kW of solar. I had the installer come out to talk about adding the battery and some insulation to the attic and ended up buying another 2kW of solar, but they wanted $20k for a different battery. I mean, I'd...

    That's what I was thinking. It does need an autotransformer, and a seperate critical loads box, but that'd be true of DIY also. Although it serves my house already or my sellback on netmetering would be higher, so instead of seeing like 4kW sellback, and 8kw bought, I'd expect to see something...

    My only thinking here is that basically a full propane tank is under pressure and an empty one isn't? So you wouldn't get as much as if you could do a full liquid fill, but you'd still be able to transfer to an empty tank.

    I planned for it when I installed the system originally, had them upgrade to the StorEdge 7600u even though I didn't have batteries, it was one of those "For a little bit more, I won't have to redo it all if I add a battery later." I've been reading through the manuals and basically everything...
  • Post in thread: Add Battery to Grid-tied Solar Edge

    Was looking into this myself recently, because StorEdge is meant to take that LG RESU10H battery. I've done some DIY EV work with batteries and initially thought to use reclaimed modules to make a DIY backup, but I stopped short because after I did some research, I don't know that it'd be worth...

    The issue you run into with Vehicle to Home is that's not the way the charging systems are meant to work. Remembering that cables have ampacity limits, the 240v 30A charging breaker won't handle inrush current for an airconditioner. The batteries in the car themselves are usually fine, but...
