Re: [RE-wrenches] Fuse sizing in battery circuits

Hi Ray, Not saying he was right, but it was explained to me by an inspector that the pipe electrode mentioned in 250.166(C) is different than a water main. The justification being that 250.52(A)(1) lists requirements for a "metal underground water pipe" electrode, while 250.52(A)(5) lists "pipe" e

Re: [RE-wrenches] Fuse sizing in battery circuits

A "metal underground water pipe" is still a "pipe" in all cases, so I think I'm missing your inspector's logic. A water main is always going to be made out of pipe, so I think the exception to 250.166 (C) should always apply. (unless some places make them square?;-) ) The difference in pipe be

On the off-chance that anyone out there is interested in an advanced off-grid training class on the 25th & 26th of this month for about $400 in Hopland, CA... The advanced off-grid course (PV 290) needs more participants lest it should be postponed until October. Just thought I'd post because I

Re: [RE-wrenches] Outback wave form

The old 50uF cap trick worked on Trace SW Inverters as well to run other Hi Efficiency washers. I thought it was the zero crossing issue, but what you're showing for PF makes more sense. I knew the caps worked, I just didn't fully understand why. Thanks, Larry. R.Ray Walters CTO, Solarray,

[RE-wrenches] BP SX mods and inverter failure?

Hi all, I know the BP SX module failure has come up often on past posts, but I was wondering if anyone has seen the failures effecting the systems inverters. I have inherited several systems from an installer who is no longer in the area. I have been picking up the task of replacing the failed/or

Re: [RE-wrenches] Outback wave form

Wrenches, While the addition of a capacitor may resolve issues associated with various inverter/appliance/motor combinations, please make sure the capacitor(s) get switched OUT of the circuit (disconnected) when the load itself is disconnected. Failure to do so could under some circumstances caus

Re: [RE-wrenches] Outback wave form

Thanks Dan. I should have mentioned that this fix is for the washer only and should be installed in a switchable circuit inside the washer or on the washer only circuit. Larry On Apr 17, 2013, at 12:51 PM, Exeltech wrote: Wrenches, While the addition of a capacitor may resolve issues asso

Wrenches, regarding installing these capacitors in parallel with the load, how do you size the capacitor, from a input current or power perspective, and also a capacitance rating perspective? On Wed, Apr 17, 2013 at 1:51 PM, Exeltech wrote: > Wrenches, > > While the addition of a capacitor may

[RE-wrenches] ground mount options?

Hello, I've been asked to put together a proposal for a local community and the only option is a ground mount (pole mount would work too). I've looked at a few options today and was wondering if anyone has any opinions on the DPW "Power Peak" mounting system? Also, I would be interested in any o

Re: [RE-wrenches] ground mount options?

Schletter has a nice small kit package if you are looking for something in AL. Terrasmart is also a favorite of ours for challenging soil conditions - their ground screws go through anything. Great team over there too. Sunlink LGMS flies up if you have good flat soil. Pricey at small sizes but cost
