The 2 Skybox inverters I installed both were based on soft start water pumps (grundfos) and a soft start air compressor for the garage. It cost more to replace the electric dryer and water heater than the solar. The owners then had a home that could run off Skybox or a small genset. These were both for Cal Fire guy's. They knew what they did not want from experience. I just helped them get there.

A rather large shortcoming for a battery inverter. I'm guessing they were thinking more of battery sell mode vs powering loads directly, but just a guess.

If you occasionally trip a breaker during the relatively rare times when the grid is out (around here at least) it is not such a big deal. But if you had to deal with that daily, you would have to be way more conservative as to what loads are allowed to be backed up. Also, is there an inverter bypass built into the BOS enclosure, or do you need to wire up a separate one in case of inverter failure.

But the software is still in flux. I have had to reject software updates that froze the system, going back to the previous version to bring it back again. One issue is that AC coupling does not work with multiple Skyboxen, unlike with older Radians. Another huge problem that seems to be software related is that dual SkyBoxen with different sized solar arrays discharge their battery banks at different rates. This becomes an issue in multiple day grid outages like we now expect in north CA fire season. You'd think the SkyBox master-slave relationship would allow them to coordinate, but this causes the one with a smaller solar array to run down it's battery sooner, faulting the system causing a complete shutdown of both SkyBoxen. OutBack says they are not fixing this, so I'm looking at SolArk for systems larger than 5 kW.

I have someone interested and am curious to hear if people have had luck with them and if they are reliable. Also, I've been seeing promo material for Fronius' Gen 24 Plus inverter, which looks like it fills the same niche. Are those even available for purchase yet? If so, does anyone have experience with these?

The 8kW has no battery disconnect, but the 12 kW has one, if you're using non-lithium based batteries.
