Re: [RE-wrenches] Hydro Diversion Controls

William, I always connect the hydro side of the diode to the diversion load with the contactor, so I don't pull the battery down while regulating. The diversion load must draw enough current to pull the hydro voltage below the absorb voltage. Use ohms law to calculate the resistance. David Katz

Drake, there is an article in Oct--Nov SolarPro which gives this type of information on 40 different module mfg's with company longevity, and which are covered by a third party insurance company: Bit.ly/SPprofiles. Thanks SolarPro. This is exactly the kind of information we need. Bill Dorsett

>From the sounds of it, Solar World has a new ACPV module to add to its line of products. My perspective is the 'strength' of a new Enphase product is more an untried risk than the established SW modules. Just a hunch though.. Jim Duncan North Texas Renewable Energy Inc www.ntrei.com

Canadian Solar has some kind of insurance policy to cover warranty if they go out of biz. Not American made, but that answers one question, I suppose. My attitude about it has been that I wouldn't count on any mfr to support warranty claims. But who really cares if modules eventually cost less tha

If it is that type of relay you are searching for, Cooper Power Systems, Basler Electric and Schneider Electric also make similar products. -Glenn Burt From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of Steven Lawrence Sent: Wedne

Losing money like pretty much everyone else. This topic brings up an important question/issue: which modcos, if any, are putting money into some kind of escrow account that can't be touched in order to cover possible warranty claims years from now? marco Hello Wrenches, How strong a co

Hello Wrenches, How strong a company is Solar World? I've been hearing that their balance sheet might not be the best. If they go under, do we loose the warranty? Is there a strong American made module? What module from anywhere can be trusted to be around for the 25 year warranty period?

Friends: I have just two micro-hydro clients, too few to have dedicated as much time as I should to educate myself. I appreciate any help on these questions: I need to rework a diversion control system. 1. I am going to use a mercury wetted relay driven by the Aux relay in an FX inverter se

Hi Conrad, Without any specs on what the redundant relay is trying to accomplish, I'm guessing you'll need the SEL 547. It's a microprocessor relay that takes voltage and current and will trip a circuit breaker provided you have a set of PTs and CTs. Steven Lawrence > > Date: Tue, 20 Nov 2012

We buy a lot of sunpumps products, I would recommend them as they are great to deal with, god products and really good after sales followup. We buy pool pumps rather than well pumps but the company has a wide range of product. On Tue, Nov 20, 2012 at 9:51 PM, Carl Emerson wrote: > Hi there,***
