[RE-wrenches] Production and Consumption monitoring?

2010-06-22 Thread August Goers
Hi Wrenches - Are any of you familiar with a monitoring product that monitors both solar production and building consumption and takes into account the differential? SunPower has a product but we have a non-SunPower client who is very keen on setting up this type of monitoring situation. Th

It sounds like your power room is getting too hot in the summer months. Adding a solar attic fan and/or more ventilation may really help keep the batteries and equipment healthier. I have seen batteries destroyed by loosing too much water during summer charging. I would try to repair or repla

Those HUP batteries are still under warranty and you very well may have a free cell waiting for you, give Rob or Jean a call at NWES and run it past them. They offer 1st rate CS and should take good care of you. You won't get much for used batteries so I would be inclined to keep them in service

If you have to parallel 4 banks do it through a buss bar, not by interconnecting cells. A few extra cables is a small price to pay for the added stability and easier maintenance. Tom From: Jeff Oldham Sent: Tuesday, June 22, 2010 7:14 AM To: re-wrenches@lists.re-wrenches.org Subject: Re: [

In this case the 4 individual banks are connected to a common buss. All four buss-to-bank cable sets are of identical lenght. Mark Frye Berkeley Solar Electric Systems 303 Redbud Way Nevada City, CA 95959 (530) 401-8024 www.berkeleysolar.com _

I'm still not clear on why everyone thinks that this is a failure which should be covered under warranty. If Rob or Jean want to give a free cell, then that's above and beyond -- but I don't think we should be blaming the battery in this case. Let's explore the situation. We've got 6760 AH of ba

Thanks Phil, I really appreciate all the input I am getting. As I mentioned, these are not the Solar One batteries, they are forklift batteries, so I am not even going to talk to NWES. I am working with the regional Enersys service center to have a guy out to cut and re-weld the interconnects

One set of batteries in a series string is best. two paralleled strings are OK, three are marginal, four or more is just a bad idea and it's nearly impossible to get them to play nice together for long. Good Luck, bob-O On Jun 22, 2010, at 5:15 PM, Mark Frye wrote: Thanks Phil, I really appre

Dana, It looks like the LightGauge is available only to their customers, similar to how we at Real Goods only offer our in-house monitoring system, PVWatch, to our customers. However, the LightGague is really a re-branded eGauge, and you can get an eGauge with all the same functionality as the Lig
