    It's extreme weather ready, so it's able to preheat itself in cold conditions and it can withstand extreme temps up to 122°.

    someone turned on the electric dryer while I was running the charging on my Rivian R1S, and the whole system shut down, cuz we went over the 12,000 W limit of the inverter.

    the solar panels will stop producing power, cuz there's nowhere for them to send it.

    That's BS, and EF marketing needs to do a better job setting proper expectations if the DPUX can't even handle your brief startup surge of 30 kW.

    This is what will plug in and feed power to the system completely powering the shop with the batteries alone independent of the grid.

    Can it power a whole house? Yes, for real. This time you can run your AC, cook dinner, do laundry, and still have power to spare.

    The Delta Pro Ultra X can do this with the SmartArtHome Panel 3, but that's an additional purchase and installation.

    For some reason, it threw errors and it just wouldn't charge even though it was within the voltage limit.

    Now, basically all you're doing is taking dirty AC power from one of those dirty generators and converting it to DC power, which is pretty stable.

    This has a 12 kW output and a 10,000 W solar input, whereas the old version had a 7.2 kW output with a 5,600 W solar input. So, it's just a little bit shy of double the input and the output on this brand new version.

  • Ports, Display & Controls-5 pts

    This new one, as we mentioned, has the proprietary charging plug, which just means if you lose this or break it or forget it somewhere, instead of being able to get a $20 one on Amazon that's generic
