Peter,
We had a client with a SW 4024 and his system was trying to power a new
Buderus boiler. The boiler controller didn't like the power quality. We
cleaned up that circuit with a capacitor and has been working great since.
We didn' have a sleeping issue, but he did have quite a few phantom lo
Rob,
I think much of your snow removal will be at your lesser test angles. 4:12
might be a problem, but here in Western Colorado we are seeing 10:12 pitch
(40 deg) shed quite easily after a storm (would be curious about the 6:12(we
don't see too much here)). I think, although we don't share sim
Hey Benn
Although we often hear the term module or panel used interchangeably, NEC
defines it in 690.2 as you wrote. A module is the individual unit, a panel
is a "collection of modules mechanically fastened together, wired, and
designed to provide a field-installable unit." The array is the whol
I have a client who is trying to sell a unit New in Box. She was advised
(by the plumber) that being an off grid specific unit it was the way to go.
Unfortunately being just a 6KW at altitude, and the size of the loads, it is
well under powered. The distributor has been difficult, so given shippi
Hey all,
I am trying to figure out how to mitigate problems found with a 12v 500w
simple DC system without a ground. This system is at 14,500' on Denali (Mt
McKinly). We experienced a somewhat "festive" fireworks display on the 4th
of July as static current from a storm seemed to travel through

Hi wrenches,
Does anyone know a good source for a reliable, reasonably priced 24v DC
clock timer 5-10A run off a relay. We are powering heat tape to mitigate a
vulnerable spot in a water pumping system for a stock tank.
Thanks,

Yes. We were told this after selling a 12K RES to a client last year. A
few months later we were advised to tell our client to never mention that it

Hey all,
I am trying to size a PV/generator system for a 10,000 ft2 off-grid

Thanks all for the good suggestions on and off-list. We are going to go

Ironically as I was looking through my TED 5000 package this thread came
through.
I am looking to use the TED for data logging for an off grid project, and
plan on connecting a computer directly to the Gateway, as the client doesn't
have internet access. I hope to use the information for system s

Hi Allan,
Oversizing the unit seems to help a bit with durability in that when
operating it's at less than full output (the con is usually increase fuel
consumption). I'm guessing that at 7800' you have about 20% derate anyway,
and I believe its a bit harder to find less than 20K. If those othe

I know the BP SX module failure has come up often on past posts, but I was

Everything is different again. I just did a claim, and things seemed to
