Hi All,
I have an AC coupled Radian that is used to back up certain loads when the
grid is down. It is paired with the Northstar Blue (Outback) batteries. The
system sits in float nearly all the time. During a recent grid outage, the
batteries had less than half the capacity that I would have
I may be wrong, but I was under the impression that most inverter/chargers
are either being an inverter or a charger at any given time, but not both.
So, once the inverter sees the AC voltage from the generator, then it will
switch to being a charger and use the generator AC power to charge the
Hi William,
Thinking out loud here, and I am guessing that there are reasons why not to
do this. But what about putting a voltage tester across each battery and
running a quick test?
I mention this because just a couple days ago, I went to check on a grid
tied battery backup system where capacity

Hi All,
I have an insurance question and am very curious about how others deal with
this, or don't. People will sometimes ask us to either do some design work
for a system that we will not be installing, or to inspect a system and
give my professional opinion about it. These are two separate work
Another one out there that is worth looking at is MT Solar.
Cheers,

Hi All,
I am curious to hear if anyone else has run into this:

It is my understanding that if the generator wakes up the grid tied
inverter and loads are more than the solar then maybe nothing bad would
happen. Although I would never do that because you don't have any control
over the loads. And if the solar production is more than the loads, then

Fascinating. I emailed the list a little while back asking if anyone knew
of a way to make a warranty claim with Solarworld. We had a system with 36
of these panels, and basically every module to module connector was crispy
and deformed as Ray mentioned. I never was successful in getting in touch

Hi all,
I am going to try out the Nuance OSPREY PowerRack as a ground mount option
that does not require an excavator. I am wondering two things about it:
1. Does anyone have experience with this, and do you like it?
2. What drill do you use for the drive rod?
It seems like the Milwaukee 2" SDS
It was a bunch of years ago, but I had seen many of these "snail trails" on
some modules. I actually took a curve tracer to them, and they functioned
essentially the same as the other modules there that did not have the snail
trails. Maybe these will be sources of premature failure in the future,
Hi William,
I recently installed these connected to an FM100, and also on a couple grid
tied systems in the past year. I think that as long as you are getting the
expected 0.6V per module you know that everything is connected as it should
be. Unfortunately I do not think that you will be able to

Thanks for pointing me in that direction. It looks like you can update some

for freq-watt control. My LG rep told me to use CA rule 21 grid profile,

Hi all,
Does anyone know if you can make the SolarEdge inverters (the A series,
before the HD wave inverters) respond to frequency control? I cannot find a
way to update the grid settings, and was wondering if anyone else has AC
coupled these inverters to a non-SolarEdge battery system. If not,
William,
If you swap strings, does the fault stay with the string, or with the
input? and if you do run without the string for a while can you determine
that the arc faults stop? Just figure it is worth making 100% sure the
fault is actually in the DC side of that one string you have isolated, and

Also being in NYS, I have been familiar with this requirement for a long
time. I believe the idea is that just like how any metal part in a system
needs to be grounded, metal roof panels under solar panels are kind of part
of the system. What if a wire comes loose and touches the roof? You would

I have a system where the solar panels (with Enphase IQ8) are on a detached

bummer
