Mac,
To the best of my knowledge, yes. I believe the most common 4.01
firmware will stack with any firmware above that number. 4.10 and
above were designed to work with the GTI for grid-tied use after
the year 2000, but should not affect stacking otherwise. I have
Hello,
I have a few hunting shacks coming up on the board so I've been searching for
DC LEDs to use. I Want to give the customers options for the tasks needed and
have spent hours searching online for products.
Any recommendations? I hate to purchase and be disappointed. Websites?

Hello wrenches,
I am contemplating stacking a Trace SW 4024 to an existing Trace SW 4024
system and converting to 120/240. I have done this before and it seemed
straightforward. Are there any challenges that wrenches have had when
attempting this? Also, is there any compatibility issues within
Some of the Power-One inverters use an extended scan on a periodic basis to
make sure they are not tracking a local maximum. In essence, they collect
an entire I-V curve, and this can take place as often as every 15 minutes.
The reason why this can cause problems with Tigo optimizers is that is can
Dick,
No, I stand by what I wrote, but I'll clarify.
If the gennie has a GFI, it will often have trouble feeding an
inverter, as the GFI will sense the ground loop and trip. The
ground loop is caused by bonds in both gennie and the first point

Allan,
I think most gennies bond the neutral to the chassis so the circuit breakers on
the gennie will trip in the event of a ground fault. If the neutrals weren't
bonded and the breakers didn't trip to clear it, there would be a shock hazard
on the chassis in the event of a fault. Not sure what yo
I believe I have tried every type of single point watering system caps out
there. These are the only units that have proven themselves over time. A few
thousand out there and not a single failure. Can't say the same thing for
others like flow-rite which I nicknamed flow-maybe.

I 2nd that idea. I'd just add that we have the tile extend a few inches
under the array, and then the roofer doesn't have to come back. It's
also a great look, as the Array is just a couple of inches above the
tile, so it appears to be almost flush mounted, and the tiles appear to
be continuo
I had reported a problem with an SMA inverter messing with a customer's heater
programming. SMA and/or SunPower (it was a SunPower leased system) very kindly
allowed replacement of the SB5000US with a newer unit that has the suffix -12
after the model number. Apparently the design upgrade includ
Jeremy,
There were many systems that used Bray oil for a heat transfer fluid back
in the 80s.
However, I would do it with a heat exchanger because some oils can be
corrosive to gaskets and the thermal diffusivity of oil is relatively poor
when compared to water or glycol. Also, the increased visc

Jason, what we've done many tines on these types of roofs is had the homeowner
work with a roofer of their choice, or we would supply one, to remove the tile
on the area where the array will be. then they put down a hot mop or suitable
roofing material and we install the racking and array over i
Anyone have any best practices or product recommendations for installing PV
on mission tile with vertical 2x4 stringers? Specifically, I'm looking at a
Ludowici mission clay tile.

Thermal Wrenches,
Has anyone ever heated an oil tank with thermal collectors?
Specifically, I wonder if the oil itself can be pumped through the collectors (
drainback or otherwise )
This is for an asphalt batch plant.
Thanks in advance!

Jeremy,
Outback may be right on, and it's worth checking.
Most portable gennies internally bond neutral to chassis, because
they expect that no typical homeowner will ground the chassis.
(Inverter-generators are a noteworthy exception to this.) Most

I found out that the appliance will work fine from an extension cord with a
portable generator.
The appliance will not even work however when the backup gen is running and
transfering through the inverters.
Outback T.S. suggested to check the Neutral to ground bond so that is the next
step. Also
Eric,
You may not be aware but some (not sure, perhaps all) MPPT controllers will
switch to simple PWM mode if there is insufficient differential voltage to
operate the MPPT circuit.
To answer Mac's question, no, there is no "good" method to use a 60 cell module
to charge a 24 volt bank, espec
