Hi William - Yea, your kWh calculation is correct. However, the 16 kWh Blue
Ion is comparable to eight L16 (6 volt x 333 Ah each) batteries, not one -
nameplate rating. Typically you can go way deeper discharge with the
lithium products, so the Blue Ion might be more comparable to sixteen (or
even
William,
August is right, the Blue Ion batteries are rated for 100% DOD so to get
the same usable capacity from an L16 at 50% DOD you'd need twice the
overall capacity. Plus most lithium-ion batteries will last significantly
longer than lead-acid so you have to factor in replacement costs when doi
Have any of you seen significant declines in SolarEdge inverter reliability?
We are having more inverter failures that at any time in the past five years
of installing SolarEdge. Lots of Code 181 hardware failures mostly in the
latest SetApp inverters (the ones without displays.)

Hey Howard,
We have started to notice this as well, we recently got 2
DOA inverters(new setapps) in a row for the same client.They were not happy
either. I have also noticed their tech support has also gotten worse with
huge wait times or call backs days later. I really enjoy their
Hi William,
I think you are smart to taking your time going to Lithium
Ion. I will let others work the math as each application/client is really
different.
I have a few clients offgrid who are early adopters and there
have been a few failures I have observed. For grid based Apps I really do

For some time starting last fall and into the spring we had several 7600
with some sort of issue, some comms, some dead, some failed in the field
shortly after install, once we did the repairs/RMA's they seemed ok but we
have moved away from them this year.

We have had countless failures on the HD Waves, I am surprised they are
even still in business. We have generally moved away from them in the last
year. I have never seen an issue with their older equipment.

The transformer is just to balance the legs, and isn't necessary to run
the heat pump with 2 inverters. On the programming, port 1 should be
/stack //1-2 ph Master/, and then set port 2 to /Classic slave./
BTW, we as an industry should move far away from this archaic and
offensive labeling.
I have used SolarEdge to AC couple a smaller Array in the past, with no
issues. I recently added a fairly significant array (6.2k DC via a SE6K
(setap) inverter in an off-grid home which has had a dual stack VFX3648 for
many years. I also added 32kWh of Blue Ion batteries replacing an 80kWh
older
sorry, prematurely emailed previous post:
I'm wondering if the VFXs are just not capable of putting out clean enough
power in order to hold the SE HD inverter. I had it operating on this same
system for a couple of hours with not this problem. Is it likely that this
inverter combo is not going to
I do not recommend AC coupling for off grid, except to offset daytime
loads or to add PV at remote buildings. Besides coupling errors like
you're experiencing, the entire system will shut down and not recharge,
if the VFX inverters shut down. With a DC coupled array, the batteries
can rechar
