Hi Wrenches,
Is anyone familiar with inverter Total Harmonic Distortion (THD) specs? I
see that SMA, Fronius, etc have THD listed on their spec sheets but I'm
looking for a spec that details requirements for grid tied inverters.
Thanks in advance.
Best,

Hi Marco - We have dozens of systems with this combo, so far no problem.
Tesla's AC coupling mechanism in general seems to be very robust - we've
paired them with many inverter types and brands, and they always seem to
couple up during our grid-off tests. Since the vast majority of our systems

Many appliances, motors, AC units, etc are rated for 230 volts, but really
they work for our modern 240 volt services. If you do a quick web search,
it appears that US standard voltages over the years have morphed from 110
to 115, to 120 volt:

Hi Jay - We are a Tesla Powerwall/Powerpack dealer. We buy equipment direct

Jason - I'm curious about your statement on cutting off module connectors.
Can you elaborate?

We've experimented around with various devices, and I'll agree that the
Microsoft Surface line is a good choice. You can find 3rd party heavy duty
protective cases on Amazon that are worthwhile if you plan on using it in
the field. Also note that the current Surface Pro 6th gen product only has

I've heard from multiple sources and confirmed myself that you can't get
the portable pdf of the NEC starting with the 2020 edition. The link that

Hi Jason -
It certainly appears that there was some sort of surge or short. We've had
a few cases where microinverter branch circuit end termination caps were
left off or fell off and shorted out during rain storms. You might want to
double check that those are all in place. We've also had cases w
Jason -
Thanks for sharing - this is a good lesson for all Wrenches. Years ago we
had a dual string inverter installation where the DC positives and
negatives were mixed between the two interters. String 1 positive went to
inverter 1, string 1 negative went to inverter 2 and vice versa. The
