Re: [WISPA] Proper 24V battery float voltage
Basically 27.2V to 27.6V at 25C -30mV/degree C temperature factor Colder temperature require higher float voltage and higher temps require lower float voltages. AGM and GEL would be the same. Wet Lead Acid batteries are different charging specs.

I'm using the MeanWell DRP-240-24 along with a DR-UPS40. It's not a three phase charger, but just limits the charging current to 2A. The voltage is adjustable at the source, and will ultimately determine my charge/float voltage. Based on my research, the highest voltage I should use is 13.8x2 = 27.6 to avoid boiling the batteries but still achieving a maximum charge. I was about to move on until I found another source suggesting that the ideal float voltage for telecom UPS batteries was 13.2x2 = 26.4. Thoughts?

Site is land locked by ghetto on one side and rail tracks on the other - commercial power is not an option. We have available a dozen or so surplus Alpha 85 amp hour gel cell batteries which test out at roughly 90% capacity (PM swaps)... The first thought was to simply charge up a battery for each event we work in the downtown core, drop by the site and swap out whatever battery is in place.. Not quite the most efficient plan. Our next thought was to place a decent sized array, maybe 300-400 amp hour, then supplement with an off the shelf solar panel or two to maintain a charge... Our equipment consists of an ancient GE MastrII repeater turned down to 25 watts and an NHRC controller. Standby draw is 125 mA, transmit ramps up to about 3.5 amps... Duty cycle is key here - we work perhaps a dozen events a year within the coverage of this repeater for about 4 hours each on about a 10% duty cycle (TX 6 out of every 60 minutes).

Re: [WISPA] Solar suggestion for ultra low use site?
You have plenty of battery capacity to handle your intermittent load so you just really have to deal with the standby load. A 10W solar panel would handle your standby load. There's a handy calculator at tyconpower.com/learning_center I would recommend a small 30W solar panel to take care of standby load and give enough extra capacity to keep the battery bank fully charged. A 12V 5A controller would handle the charging of the batteries and your load. Some prices from beezwaxproducts.com 30W 12V panel $179 12V 5A controller $24.95 Scott -Original Message- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of AJ Sent: Friday, January 15, 2010 11:38 AM To: WISPA General List Subject: [WISPA] Solar suggestion for ultra low use site? Thought I'd tap in to the collective intelligence of the WISP group for this question... Looking at setting up a solar powered VHF ham repeater in the middle of a metro area for infill coverage... Site is land locked by ghetto on one side and rail tracks on the other - commercial power is not an option. We have available a dozen or so surplus Alpha 85 amp hour gel cell batteries which test out at roughly 90% capacity (PM swaps)... The first thought was to simply charge up a battery for each event we work in the downtown core, drop by the site and swap out whatever battery is in place.. Not quite the most efficient plan. Our next thought was to place a decent sized array, maybe 300-400 amp hour, then supplement with an off the shelf solar panel or two to maintain a charge... Our equipment consists of an ancient GE MastrII repeater turned down to 25 watts and an NHRC controller. Standby draw is 125 mA, transmit ramps up to about 3.5 amps... Duty cycle is key here - we work perhaps a dozen events a year within the coverage of this repeater for about 4 hours each on about a 10% duty cycle (TX 6 out of every 60 minutes). The rest of the time the repeater sits idle and will not transmit unnecessarily (no IDs or anything unless it's actively in use)... What is out there on the market for a low cost solar site?

Have enough battery capacity to run for 7 days with zero charging. This will give you a window of response time if the charging system suffers a failure (or theft/vandalism) or there is an extended episode of inclement weather. 2. Avoid as many power conversions as possible. 3. Avoid any equipment that has a built-in cooling fan. 4. 48 volt power systems are more efficient than 24 volt power systems are more efficient than 12 volt power systems. 5.

Yeah, We don't have the higher capacity yet. For instance our largest panel is 30W right now and our largest controller is 5A. You could use 3 30W panels and 2 5A controllers but I wouldn't suggest that because it's too costly.

I used 4 hours of sun for your location based on another post I saw. I used 24 hours extra battery capacity. You may want to increase or decrease this depending on the reliability of the sun in your area. You need 73 watts minimum solar panel capacity You need at least 88 Ah in battery capacity This is bigger than the stuff we offer right now but here's a starting list: 1. 85W solar panel - You should be able to get for about $350 or less 2. 12V 8A Solar Controller - You should be able to get for $60 or less 3. 100Ah battery - You don't need a deep discharge type because the solar controller will disconnect the load when the battery voltage reaches 11.1V which protects the battery from over discharge. You just need a type that has good performance in cold weather. You should be able to pick up a battery for less than $200 4. You'll need a mount for the solar panels try here: http://power-fab.com/products.htm They make all kinds of mounts. I'm not sure the cost. 5. You'll need a vented outdoor enclosure if you are putting the battery inside. I've seen people put the battery in one of those plastic battery cases you see in small power boats and then the enclosure requirements for the controller and electronics becomes easy. We have suitable enclosures for $70 14x10x5 Polycarbonate outdoor enclosure 6. Wiring is quite simple. Any decent vendor will warranty the panels for 20-25 years and the solar controller for 1 year.

Time is short on this project and I need a lot of help. I've never done a solar project. Never really even looked at them due to the costs I've seen tossed about. Now I have a customer that's willing to purchase the initial equipment needed to cover his community. The ONLY way into the area is a hill that's within sight of my tower and NOT anywhere near power. I'll be able to just run a single MT board with two radios in it for this site. One backhaul and 1 distribution. I'll guess that I'll have less than a 2 amp draw (probably much less than 1 amp in reality). We don't often get long periods of no sun. Could be days of fog or low clouds in the winter, but mostly we'll have a lot of sun. On the foggy or cloudy days we often don't have enough wind to worry about wind generation. I think. So, please clue me in on what to buy, who to buy it from (vendors welcome!) and anything else I'm missing. Thanks all! marlon WISPA Wants You!

Re: [WISPA] TP--UPS-DC-12-9
The power from the controller to the radio board is essentially the battery power. So with full battery it's about 13.4V and it takes about 26 hours at 3.5W to reach 11.1V. This is a gradual voltage slope so you could set a warning at 11.5V and you'd have some time to take some action. At 11.1V the controller turns off the power to the radio in order to keep the battery from over discharging. If discharge batteries too much it reduces the life of batteries. If you want to run at lower battery voltages, you can add one of our TP-DCDC-1218 or TP-DCDC-1224 DCDC or TP-DCDC-1248 DC to DC Converters between the battery and the radio board. These units will give regulated 18V or 24V or 48V DC voltage from inputs as low as 9V. They have a built in POE inserter and 2 isolated power inputs.

The RB230's and I think as well the RB532 could/would over SNMP report power levels and temps maybe the newer boards can't report temp but can report power over SNMP. If I didn't understand Scott incorrectly the power supplied out from the controller is stabilized so you will either work or your dead. So to use DC voltage report you would need a separate board feeding directly of the battery and as power on the battery start to drain your NMS would have to trigger on a low voltage problem. There is another issue here.. That is that the UPS battery is 12V and most RB dies or fail when the power goes under 11V. So the window of opportunity would be very small.

One solution which probably is the cheapest one and goes in line with your Linksys unit would be to bastardize a Bullet2 (the $39 Ubiquiti device) and either use it with the standard AirOS or load on your own software. In full TX mode it uses 4watt and I would guess no more than 1watt if the transmitter is disabled unfortunately the exact load levels are not in their datasheet just the 4watt number.
