Re: [WISPA] DC Inverter help
I'm curious if anyone has a) connected external batteries to an APC UPS... AND ... used the APC SNMP card to monitor the status of battery consumption. I currently use APC SU700NET UPSs in external 6-deep boxes to condition power and provide battery backup. The SNMP card (AP9617) will e-mail our support if the site goes on battery power, giving us about 2.5 hours to get up the hill with a generator. When the batteries go below a threshold of charge left, it e-mails to let us know it's in a critically low charge state. So, if we put on extra batteries, does the UPS know this and does it know what kind of runtime it has left?

Re: [WISPA] DC Inverter help
Gang, I'm not a UPS expert, but if the batteries were deeply discharged, wouldn't the extra load of the external batteries would make it hard on the ups when it tries to bring them back up? Maybe I misunderstood the question; but, if I needed 48VDC uninterrupted, I'd string 4 deep cycle batteries together and connect a good multi-stage battery charger. Then I'd run my 48 V devices right from the batteries. If you don't need 120AC, then there's no need for a UPS. If the UPS is already there and uses a 48V stack, then I'd tap into that...

Re: [WISPA] DC Inverter help
Joe, 1. Right, every time you convert from one type of power to another you're only going to get 80 to 90% typ. Some devices claim up to 98% eff, but that's only over a very specific operating range. Most inverters are terribly inefficient for small loads. Some use 20 or 50 watts just idling! So coming right off the batteries will give you the longest runtime in general. 2. A good charger stops when it's supposed to. A cheap-o charger from wal-mart could cook the batteries. You need a good charger that has several charging stages to take good care of the batteries. The solar electric people like Outback and Xantrax make excellent ones, but they're expensive. There are inexpensive units that do a good job too. Just make sure that they back off the output when the batteries are charged. Look for something called a float charge. Sometimes chargers that have a trickle charge as the last charging stage will cook a battery over time. There are dc-to-dc converters (check mouser.com and digi-key.com) that can take a wide range of input voltages and deliver a consistent output voltage. These allow you to really discharge a battery and keep your equipment running at a constant voltage. For instance, a dc-dc converter could take 12 volts from a battery and deliver 48 v. Even as the battery discharges to 9v or less, you could get 48 v. This however is REALLY hard on the batteries, which are considered to be completely discharged in the 10V range. How it will behave will depend on the charger and the load. Most good chargers have 3 or 4 charging stages and choose the correct stage depending on how deeply discharged the batteries are. It goes something like equalize-bulk charge-maintenance charge. I have a feeling that with a small load like an AP, the charger would oscillate from charge to maintenance charge over time as the batteries are slightly discharged, then recharged, slightly discharged, recharged... Or the maintenance charge might be enough that the batteries see no discharging at all. It'll depend on the charger. Here's one of my favorite links about batteries: http://www.uuhome.de/william.darden/carfaq.htm I've been studying up on it for quite a while now because I'm building an off-the-grid home.

[WISPA] some legislator and legislation FYI
I dunno if this will help anyone or not, yet we received this today after filing last week as requested on the list(s). *** Thank you for contacting me on network neutrality. I appreciate hearing from you on this important issue. I co-sponsored the Snowe-Dorgan 'Internet Freedom Preservation Act' (S. 2917) because I believe that when it comes to the future of the Internet, there is nothing more important than preserving a system that fosters innovation and is free from the discriminatory practices that may stifle competition and restrict access to the marketplace of ideas. It is urgent that Congress take action now because after last year's U.S. Supreme Court decision and subsequent rule issued by the Federal Communications Commission (FCC) to deregulate broadband over phone lines, there is no law that prevents network operators from giving its own content and services preferential treatment over that offered by unaffiliated parties. Last August, at the same time it deregulated broadband over phone lines, also known as DSL, the FCC adopted four net neutrality principles. They are: To encourage broadband deployment and preserve and promote the open and interconnected nature of the public Internet, consumers are entitled to access the lawful Internet content of their choice. To encourage broadband deployment and preserve and promote the open and interconnected nature of the public Internet, consumers are entitled to run applications and use services of their choice, subject to the needs of law enforcement. To encourage broadband deployment and preserve and promote the open and interconnected nature of the public Internet, consumers are entitled to connect their choice of legal devices that do not harm the network. To encourage broadband deployment and preserve and promote the open and interconnected nature of the public Internet, consumers are entitled to competition among network providers, application and service providers, and content providers. While these principles were an important first step, they do not fully address the range of concerns, and more importantly are not enforceable by law or regulation. As you may know, on June 8, 2006, the House of Representatives passed the Communications Opportunity, Promotion, and Enhancement Act (COPE), which grants the FCC authority to enforce its August 2005 network neutrality principles in complaint proceedings. In addition, COPE would establish fines of up to $500,000 per violation and require the FCC to resolve network neutrality complaints within 90 days. A stronger net neutrality amendment, addressing the issue of non-discrimination was offered and defeated at the Energy and Commerce Committee mark up of the COPE Act as well as on the House floor. In the Senate, on May 1, 2006 Senator Stevens, Chairman of the Senate Commerce Committee, introduced the Communications, Consumer's Choice, and Broadband Deployment Act (S. 2686). The first version of the Act only required the FCC report annually to Congress on net neutrality and make recommendations if necessary. Even though subsequent drafts of the Act improved on the first version by adopting language closer to House-passed language on net neutrality, overall, the net neutrality provisions in S. 2686 still fell far short of what I believe is necessary to protect consumers and businesses that rely on the Internet. At the Senate Commerce Committee mark up of the Act, I co-sponsored an amendment with Senators Snowe, Dorgan, Boxer, and Kerry that would add a critical fifth principle to what the FCC adopted last year and make all the principles enforceable. The fifth principle is a non-discrimination principle that states simply end users shall be entitled to service from each broadband Internet access provider that does not discriminate in the carriage and treatment of Internet traffic based on the source, destination, or ownership of such traffic. After a long debate in the Commerce Committee on June 28th, the amendment failed on an 11 to 11 vote. The Act was subsequently reported out of Committee to the full Senate without my support, largely due to the lack of non-discrimination net neutrality amendment. Please be assured I will keep your views in mind and continue to fight for a fair, enforceable, net neutrality language to be included into the Act if and when it gets to the Senate floor. Thank you again for contacting me to share your thoughts on this matter. Finally, you may be interested in signing up for my weekly update for Washington state residents. Every Monday, I provide a brief outline about my work in the Senate and issues of importance to Washington state.
