Energy-Jason Posted April 24, 2013 Share Posted April 24, 2013 2 x 45Ah Ritar 1 x Steca PRS2020 2 x 150W Panels. The high site services farming network with 12 links. Bit too much power up there 1 x 150W would of been fine I think. E Quote Link to comment Share on other sites More sharing options...
Wetkit Posted April 24, 2013 Share Posted April 24, 2013 Looks good to me. Why such small battries, or is space a problem? Quote Link to comment Share on other sites More sharing options...
Energy-Jason Posted April 25, 2013 Author Share Posted April 25, 2013 Hi Wetkit The Mikrotik Radios total draw is about 16W per Hour at 12V About 1.3Ah. 31Ah per day. The Batteries seam to Discharge down to 12.2V just before Sunrise. About 60% State of Charge. We only had capacity for a 100AH Battery. So figured 2 x 45AH would preform better than one large 100Ah Keen to hear your opinion on this. Regards E Quote Link to comment Share on other sites More sharing options...
Wetkit Posted April 25, 2013 Share Posted April 25, 2013 See, I thought MT equipment runs better on 24V, and from there the two battries in series perhaps? Quote Link to comment Share on other sites More sharing options...
BenDL Posted April 26, 2013 Share Posted April 26, 2013 Would be interesting to see if you will get through a couple of cloudy days on that battery capacity? I would think not, especially if the batteries start ageing. Energy-Jason 1 Quote Link to comment Share on other sites More sharing options...
Energy-Jason Posted April 26, 2013 Author Share Posted April 26, 2013 Hi Ben Thanks for the post. Also a bit worried It's been going for about 700days now. But I think we might be excercising the batteries to much. Keen to hear your thoughts. Regards E Quote Link to comment Share on other sites More sharing options...
BenDL Posted April 26, 2013 Share Posted April 26, 2013 Well if you have done nearly 2 years without interruption, then you had it pretty much spot on! You think you would get it to work even with half the panel capacity? What life-expectancy are your expecting from the batteries? Quote Link to comment Share on other sites More sharing options...
Energy-Jason Posted April 26, 2013 Author Share Posted April 26, 2013 Hi BenDL Great to hear from you. Funny you ask Our guys have just informed me that we are only running a 120W chinaland solar panel up there now, as they changed it to 12V Here is the attached voltage of the main radio that runs the HS. It measures the battery Voltage. Its a screen shot at 3:40pm. I will take another screen shot just before the sun rises Will be interesting. They say the float life of ritar is 9 years, But I think we cycling a bit deeper than that. Keen to hear your thoughts E Quote Link to comment Share on other sites More sharing options...
