Good or Bad idea – FEMA, DHS and FCC will conduct first national test of the Nationwide Emergency Alert System (EAS) test

First of… THIS IS ONLY A TEST.  TEST TEST TEST.

Just so you are aware…on Wednesday, November 9, 2011, FEMA, DHS and FCC will conduct the first national test of the Nationwide Emergency Alert System (EAS) test. This nationwide test will kick off at 2:00 p.m. (EST) and run concurrently across all time zones.

This system test is the first of its kind designed to broadcast a nationwide message to the American public. In the history of the country, nothing like it has been conducted on such a level. As you may be aware, there have been tests in the past, but not of this magnitude encompassing all regions of the Nation simultaneously. The three (3) minute test will run concurrently on all radio and TV band stations exceeding the previous messages broadcast which were anywhere from a 30 second to 1 minute message.

There is great concern in local police and emergency management circles about undue public anxiety over this test. The test message on TV might not indicate that it is just a test. Fear is that the lack of an explanation regarding the message might create panic. Please share this information with your family and friends so they are aware of the test.

Below are two websites that will provide more information regarding this test:

Verizon LTE pinhole virtual server

wow..I see its been some time since I posted here..have to update the home data soon..

 

Anyways I did have a major beef with Verizon wireless LTE 4G network.

Im a network manager and have been dealing with Hurricane Irenes effects this weekend where as our local fiber is out to our main office due to tress falling.  This being anticipated before it happen we went and puchased a handful of Verizon wireless LTE 4G modems UM290 and some cradle point routers  CTR500.   We found that Verizon wireless is out of IPs with the boom in expanding their 4G lte network so everyone is behind a NAT.  This prevents you from using whats called Virtual server and or Pin Hole from the outside world into your corp network servers.   Only work around is a $500 static IP LTE account or go back to the 3g legacy network.  Guess we will be going to Sprint / Clear which doesnt do this.   Hope this helps others trying to get there networks online during this disaster.

 

Spring update

Well it was an interesting winter with 4 snow falls two of which were 10″ and I think an 8″ fall but spring is here and the plants are coming back. Laurie has been hard at work with planting flowers in the beds front and back while I spread 10yards of black dirt on the low spots in the yard.  Some of the garden was planted but with our new puppy ‘ Bear ‘  its going to be a challenge to keep him from digging up new growth.

Solar PV,  Everything is going very well for systems.  Jan was a raining month so we saw our highest electric bill up $100 over the norm because we didnt generate much solar power. Feb/Apr however are rocking hard and I think we actually broke a summer month with power generated.  I have recently change Electric providers as TXU our former cut us a quaterly check for excess power sold back to the grid where as other providers will just issue you a credit on your current bill.  Also TXU wanted the Green Tag or RECs we generated and I didnt want them to have it based on the cheep rate they purchased power from us so now we get to keep our REC and sell them at a later date to any third party.

We are looking into Wind power now either pole mounted or roof.  Being inside the city limits tho will have some zoning issues to address. Local HOA probably wont be an issue since its just our block but city might be.  One local installer said we could always just do it and sue back the city for not being green with a pro-bono lawyer but not sure we want to go that direction.  Local cities do need to loosen up zoning rules for wind and solar power generation however in my opinion.  Times are changing and if you can be good to the planet…why not.  I am however really looking at adding a second Xantrex inverter to our solar system to cover the startup surge from the Geothermal units which we cant do now.  This would give us 12K of on demand surge power using existing panels and batteries.

Geothermal heating went smoothly with no issues.  Nice to have any zone heat or cool within 5 min time.  I am building a homemade water level meter for the geo-water reclamation tanks with 3 floats and a light box so I can know at any time what the water level is in the underground tanks.  Since a submersible well pump is used for irrigation its motor is raises the pump intake up 12″ from the bottom of which empties the tank when all sprinkler zones run for just around 50min.  Having the floats connected to a relay will atleast kill the sprinklers if the tank empties out and keep the pump from burning up.   I really would like to see how I can lower the pump completely or swap it out for something else without a lot of hassle.

Ill be uploading a new picture gallery soon as I have taken the old gallery offline due to some security concerns.

4MW Solar Electric Generated

I thought I had posted this but guess I did not.

On Aug 26th 2009 we had self generated 4 Megawatts of total solar electric power using the 30 panels outside.  I think our worst power bill this summer has been $320 which includes the pool pumps running about 8hrs during the day.

Above is my desktop widget showing real time power generation.  The money saved is an estimate based on local rates. It however does not include buy back rates or REC credit pricing.

Solar update – 3Megawatts generated

Well its July 29th and its been hot and sunny the past month. We got our power bill today so I sat down to condense my daily/weekly reports from the solar array putting things into perspective.

Mid June – Mid July we used 3728 Kw from the grid and the solar array generated 1080Kw. Our current grid power rate was billed at 10.0cents/kw so we saved about $113. You could say were generating about 33% of our needs. Avg daily temps were 100 so the Geo units were humming away plus running the pool pump about 8hrs/day can build up a load. System total of solar power generated is over 3.3Megawatts!!!

Ive been asked over the past months how long our solar inverter batteries will carry the home so I ran a night time test.  At 8pm with no sun shining I cut the grid off with the 400amp switch and manually powered up the Xantrex inverter using the 4 marine batteries.  I did shut down the pool and Geo Air conditioners to see how the system handles just the bare essentials like minimal lighting, a tv, refrigerators and all that phantom power likes clocks and dvrs.  Things ran smoothly for 1.5hrs without any issues. No lights pulsing or the like were seen during the test.

I did run the pool pump and the basics without any problems.  The Geo well pump also runs just fine pulling an  estimated 1400watts…ouch.   I did not power up any Geo units for this test but will on the next.  We will add another battery bank of 4 marine deep cycle batts which will double the run time.  I have to watch however just how many sets of 4 I add. If I add 1 set to many the sun will take to long recharging them if I use only the sun.  The Xantrex does have a setting to allow grid recharging or not.  Today its cloudy so I enabled grid recharge which took a little over an hour to bring the batteries back to full charge.  Atleast I know the inverter is fully working.

An update on TXU and excess power buyback (what we sell back).  We received a letter a couple weeks back offering 7.5cents/Kw sold back to the grid. They also wanted my REC or Renewable Energy Credits which I didnt like.  After a couple calls to TXU and saying I want compensation or strike that part from the contract I guess this created a little fuss in the office and they were going back to see what could be done.  Ive read on another website they are rewriting the contract to not include the RECs which is fine if they choose not to buy them from us.  Some states are buying the RECs for 13cents up to 20cents/Kw and some others offer up to $90/Megawatt.

Not much else new on the solar subject.

Time lapse of the pool construction

I cleaned up the webcam data of the pool construction and created a time lapse of it.

Pool by:  Stone Creek Custom Pools,  Fort Worth Tx.

Dave Betts of Fort Worth Texas based Stone Creek Custom Pools started work with excavation back in Oct 2008 and completed it 5weeks later.  We gave him our ideas and rough drawings of what we were looking for. After some changes and touring 3 other pools to see what we wanted in the Grotto and possible slide we finally had a 3D plan ready.  After a  few short days waiting on the city permit we started digging which was less than a day.  All the contractors were very professional and one even worked over time to beat some approching rains.  Laurie had her 1st pool also done by Dave Betts back in 2005 which came out great so we already had a very comfortable feeling working with Dave and costs on this project.  On New Years day the pool was filled and with some chemicals to clear up water everything worked right from day 1.

1Megawatt Generated !!

In the last couple days, during weeks of cloudy days and spring rains, the sun broke between the clouds enough to push our solar pv system over 1 Megawatt of generated power!!!  The Xantrex system is reporting the the lifetime statistics – Energy produced is 1.022MWh and some 623.6lbs of CO2 Avoided in under 3 months time.  Altho nobody sees CO2 its more of the fact that we were that independant in generating our own power. Even on a fully cloudy day the system will produce 200-1000watts which is suprising.  So dont let anyone tell you that you need full sun and anything less gets you nothing.

Our local power provider, TXU on the other hand is still dragging along with any sort of billing package allow for the excess power that HAS been pushed back into the grid.  Each email and phone call for the last 2months comes back with, give us a couple more weeks.  Last month I change our daylight power loads to be the heaviest with the pool running during daylight hours as to not push to much excess back to the grid for now.

The landscaping has already been growing with the warmer days pushing 90 and all the rain.  The Geo-thermal A/C fills the underground reclamation tanks enough that we water half the lot in the mornings and by the evening the rest of the property.  Depending how the home reacts to the hot summer the tanks might fill even quicker but with the foam insulation we can already tell the house doesnt loose much to the outside elements.  By the end of next week I should also have a report back on the air-quality of the inside that our HVAC company is sampling with a small in home monitor.  We arent expecting anything suprising but we want to make sure the home has enough fresh air.

Earth Day 4.22.09

Well its Earth Day Apr 22, 2009. I don’t know if its  going to get a lot of press we are going to do our part and document it right here.

At 10am central I will disconnect our Oncor grid connection and run the home completely on solar pv.  Weather is  going to be sunny and 93′  here in Fort Worth Tx.  so the test of the foam insulation, UV tinted windows and geothermal A/C will pay off.

I will post times and home status below during the day as my time permits. Solar production below is what the home is only requiring electrically from the solar arrays.

Time:   Outside:   Inside:          Solar production:    Oncor grid:

08:30     Sunny 65′    Kit72,Attic64   Shade – 118 watts    Connected

09:45     Sunny 71′    Kit73,Attic73   50%sun- 815 watts   Connected

10:03     Sunny 73′    Kit73,Attic76   90%sun-1015 watts   Disconnected

12:05     Sunny 82′    Kit74,Attic88   100%sun-1751watts   Disconnected

15:07    Sunny 90′    Kit74,Attic93   100%sun-1626watts   Disconnected

17:03    Sunny 92′    Kit75,Attic98    100%sun-2015watts  Disconnected

17:10  We went back on grid before the sun’s angle gets too far to the west.

All in all..things went pretty good today without the grid.

On another subject tho I’ve learned the TXU who is our local REP or Electric reseller of Oncor power hasn’t got there act together with the Net-Metering customers and its 40+ days past the original deadline of March 15th.  This means that in our case all the excess power we pushed back to Oncor/Txu didn’t credit us for our current bill.  Tho we reduced our usage overall approximately 83Kw is in limbo uncredited back to me.  I’m told TXU management wants to make sure they do it right but they knew this was coming last year and already they blew the deadline.

From reading other forums it seems I’m not the only case in North Texas and probably not the last.

Green Mountain Energy tho does have it in writting and is crediting customers Penny for Penny.

Guess Im making a call to the PUC next week to see if I have any ground to file a complaint.

Earth Day 2009

On April 22, 2009 in observance of ‘Earth Day’ we were going to  disconnect our electric grid and power our home completely by our new solar PV 6KW system but in testing the system 2 days early we can generate more than we consume so it makes sense to push clean power back into the grid than to simply not use it.

In a test today 10am, with full sun, 90% of the system was in full sun.  Grid disconnected we use about 14-18amps with basic loads. Testing of the pool kicked it up to 28amps needed, Geothermal A/C without pool put us at about 45amps.  The battery was being used a little but it never drained them.

By 1130am the panels had full sun and the batteries were charged 98%.  I connected back to the grid and waited for the inverter to sync up ( 300 seconds delay ).  While waiting I watched the outside meter which took about 20seconds for a full rotation. When the solar was back online the meter took about 10seconds to spin backwards proving we are making more than we need under normal load.

This shows us that if the grid fails we can support ourselfs with everything we need just fine. We will have to share the power with the heavy items like the AC, Pool or Oven on a one at a time basis but everything else, lighting, frigs, PCs, TVs, Washer/Dryer will be working just fine when the sun shines.  If we feel that increasing our battery run time into the PM hours or cloudy days is a concern then we will have to invest in a larger battery bank as right now its only 650amps.

Solar Array2 Done!

I took off Good Friday to work on array 2  as bad weather was heading our way for the Easter weekend.

Since I had the racks ready I ran out a guide string for the lower row to keep things lined up best as possible and started the bottom row. My dad came up to help install the last 15 panels which really only took us about an hour & half.  The clips from Unirac do speed things up vs having to screw the panel frames to the racks.  Since this rack is in running up and down vs side to side Ill have to come back next week and make a couple of minor adjustments to level a couple rows perfectly with the adjacent row.

Saturday I spent the day connecting up the wiring strings and tie wrapping everything to keep it clean.  Last was the final connection to the E-panel inside the garage and triple checking my voltages from the arrays. Each array without a load on them is producing 91volts at the racks and 89volts dc at the inverters input.  With the last check I powered up the system and waited for the countdown of the inverter to complete.  I set the remote to Sell power and the invert started humming big time.

About a minute in tho the PV breakers tripped and shutdown so I had a problem. After looking things over and watching breakers tripping I placed a call to Mid-Nite solar and left Robin a voicemail with the issue.  Not expecting a call since it was the weekend my phone rang back in 5min with Robin on the line.  He went over my wiring and hardware list and said I needed to make a change to my PV wiring as the charge controllers were fighting for the full load and tripping.  A quick trip to Home Depot and quick change to the wiring and things started once again.  This time the power up worked and the Xantrex showed 4800 watts being produced !!  Thank you Robin for calling me back else it would have been a long quiet weekend waiting for Monday.

I checked my TXU meter and now it was really going backwards, by the end of 3 hours it had already sold back 3Kw excess and my daily peak report showed 5.9Kw max output.  Next week is to be sunny so Ill have some really good numbers.  I also was stopped by a neighbor we know asking if that was solar. They want me to visit there home and see if they can also install solar for them as they think they have a south facing roof with space.  Its good that poeple want to do this and it does give you a good feeling of independence.
