[RE-wrenches] Skybox

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.

thinking more of battery sell mode vs powering loads directly, but just a

Is the 5kw limit and no surge capacity for the backed up AC
loads only when operating off grid? 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. Cheers, Dave

hardware, if you don't need big surge capability. 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. Don

Hi All,
Does anyone have experience using
Outback's Skybox inverter? 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?
Cheers,
Dave

HI Dave,
The reason I?ve not
used it, is that is has no surge.
You might also look at the Sol Ark

I second Jay's suggestion to
look at the SolArk. The 8kW has no battery
disconnect, but the 12 kW has
one, if you're using non-lithium based
batteries.
