Same. We've started calling our initial $100k+ proposals the 'kiss of
Death' since we tend to never hear from them again. It's a good way to weed
out those who aren't willing to spend the time/capital on a system that
will actually perform what they're asking (reliably!).

Re: [RE-wrenches] Large off-grid inverter/storage

[Ray]

Here in Colorado, I've been called upon to do a few design bids for 
these.  I always charge a healthy design fee to eliminate the tire 
kickers.  You can spend quite a bit of time just characterizing the 
loads, only to lose the client when they find out its going to be 
several hundred thousand dollars.

Is “25 Kw per hour” a real value? For us old school people there is kW 
and they is kWh (kilowatt hours). I’m guessing that it is 25 kWh per 
average day, or, about 750 KWh / month.

Re: [RE-wrenches] Large off-grid inverter/storage

[Starlight Solar Power Systems]

Hi Andrew,

Any phrase that includes “per hour” while describing power use, generation or 
storage in a RE system is probably a misnomer. Think about it: you could just 
as well say 25kW per second or per month. That’s because kW is a term that 
describes a rate or power, not a quantity of energy used or stored; kWh defines 
that. 

In our retail store I have heard this term hundreds of times. While I am 
describing the difference between Watts and Watt-Hours, which is typically the 
source of  confusion, I ask, “Would you say that your car has a 200HP “per 
hour” engine?” No, you would just say 200HP because you are describing power.

So, if you meant the combined loads require 25kW to operate, use that number to 
determine inverter or generator sizes. If you are describing 25kWh of energy 
use or storage, use that to determine power production and battery bank size.

To your question: I am a fan of using Li-ion batteries for the long life, 
weight and space savings, no maintenance, much higher charge rates, fastest 
recharging, and the 40% reduction in the PV system size compared to LA storage. 
Plus you get battery protection and monitoring included. Since you never have 
to fully charge them, for offgrid use, the advantages are huge. For people 
making  growing weeds, buy the best. Contact me off the list if you would 
like more understanding about Li battery storage.

Re: [RE-wrenches] Old Outback Mate question

[Kent Osterberg]

Allan,

I believe the original Mate is still available. At least my distributor 
still has them in stock.

Wrenches,

I have a customer with a 2005-era Outback VFX3648-based off grid 
residential system. Her original Mate had lost response on several of 
the six buttons. I told her that the Mate is no longer made, and a 
Mate3 is larger (won't fit her space), expensive and overkill for her 
needs. I offered to attempt to repair hers, as it seemed to me that it 
would be a simple task. I removed the cover and the silicon button 
molding, and used a Q-tip with a bit of electronic cleaner and 
lubricant from Radio Shack to clean the contacts. When I put it back 
together none of the buttons made active contact.


- Any idea what I might have done wrong to cause further failure? I'm 
wondering if the cleaner included an oil that hindered conductivity, 
rather than enabled it, and whether trying again with denatured 
alcohol (or something more potent still?) might resolve the problem.


- Any suggestions about how to correct the (fairly common) problem of 
the buttons not making contact after years of service?


- Anyone repairing older Mates that you might pass on?

- Any way to buy a new or refurbished Mate?

Thank you for any help here.,

Allan

One can't simply take a power bill
from a utility and try to duplicate it offgrid. The loads have to be

Re: [RE-wrenches] SMA phantom arc faults

[Mac Lewis]

Hello Wrenches,

You may be aware of this but the -92R firmware supposedly has addressed the
arc fault issue for the US-40 inverters.  See here for the download:
https://www.sma-america.com/service-support/downloads.html  It fixed an arc
fault issue for me yesterday at least.  Bring a thumb drive, the update
process took about an hour to perform.

 Interestingly, the problems I've had with the SMA -40 AFCI faults have

 pretty sure I've seen where you can disable it?

 At least with the TL-22s, the AFCI function can be turned off. You need
 a* Web connect speed wire module*. .I don't know if this same protocol
 will work for the TL 40s or not.

 Metal roofing can apparently be affected by radio waves and by other
 factors that create a disturbance that can trigger the AFCI.The TL 40 was
 supposed to overcome this problem.

 [RE-wrenches] SMA phantom arc faults


 Aloha all,

 My company has really been struggling with the SMA US-40 line of
 inverters and incredibly disruptive to positive customer experiences bogus
 arc faults.

 We were told by our SMA friends that a firmware update/fix was
 forthcoming in mid-August and we've heard nor received nothing last month.

 Does anyone know anything as to where they're at on this?

 Really frustrated

 marco
