I would like to see the LFP price come down in price, I have seen some
cheap POS's coming out of China $3800 for a 10kWhr battery but they have
very little surge capability so the LBCO shuts down the inverter, Blue

I want to ask about the cost of lithium batteries.
Tesla seems to be telling the market that LFP batteries are way cheaper than
NMC, and that they are switching to LFP, at least in China.
From what I see in the marketplace that’s a lie.
So I want to know from the lithium experts what they
Ours were all early versions of their HD Wave inverter, strictly
residential. All of our earlier A series have been quite reliable. Have not
had issues with the optimizers themselves.
Since we stopped using them we don't know if the newer(screenless) versions
are any better. Hasn't been worth the
Hups do come with a battery pulling tether or did come with one.

Jay,
We’ve had lots of SE failures. Maybe not hundreds. Certainly dozens. Every
level from small residential inverters to their 33 kW 480V units. And
optimizers, though far fewer optimizers on a percentage basis. From an
inverter perspective, the location doesn’t seem to have mattered
Statistically it seems unlikely that installers who have both installed a lot
of the same equipment would have such different results.
I’m wondering if there are some common issues with SE failures.
We’ve heard now from numerous installers with lots of failures and others with
almost none.
August,
One quick note about your last sentence. I know you are talking about
swapping black and red on an Enphase branch circuit, which is not a
problem. However, landing L1 from string 1 with L2 from string 2 on a
2-pole breaker and vice-versa does matter. For correct OCPD operation, you
need
For rolling thru a building, I bought a “safe mover”: $569

It has 2 end sets of turnable poly-urethane wheels, hydraulic jacks on both
ends, & ratchet straps that connect one end with the other end.
Rated at 3000#. Great
We've installed lots of Enphase, SolarEdge, and the various string
inverters over the years. As far as Enphase goes, our experience is not too
far from what Jason described - we had thousands of the M190/M210
generation installed and experienced a very high failure rate. Our failure
rate on those
Enphase's early failure rate was ridiculous, but we are finding that once
the faulty M190's were swapped after the first few years, the ones that
didn't fail have been relatively solid. In other words, let's say
(unscientifically) 30% of the M190's on a job installed 10 years ago failed
