2 170 watt panels in series 110ah 12volt bank. With my victron 75/15 mppt on sunny day i show average of 44 volts 6 amps on pv array and 15 amps (max for my controller)battery charging current.. . For test purpose i drain battery to 11.80 then activate pv breaker at noon.My panels are rated at 9 amps. Mppt controller is impressive getting max charge current. fuse on pv array. This is on my house Roof. This is my solar system
Separate System
I live near the water on south shore of long island. Lots of trees. Lose power all the time. Have a generator but not needed for just a few hours. I use my 200ah agm battery and a 600w Xantrex Prosine inverter. I charge the Battery just once a month for 24hrs. Its strictly for backup power. I hope once a month is ok. Any thoughts on this? I can run TV, satellite reciever, 2 Led Lamps, phone and my router.Also Cpap machine. All that is about 490 watts. Its Goes for 6 hrs before my inverter beeps. So i go 5 hrs and shut off everything and can sleep all night with cpap machine. My 340 watt solar array is hooked up to my 110ah battery as i noted in first Paragraph. I use this for my landscape lighting for front and back of House. I use about 2 amps dc in winter and 4 amps dc in summer. Never a problem charging. Sunny day its on Float by Noon. Cloudy day takes longer but it still makes float by 3 or 4pm.
On a sunny day i used my solar system with a cheap 700 watt inverter. I plugged my marine charger into it so i can charge the 200ah battery. I then turned on my 600 watt Xantrex inverter with everything running. About 490 watts. I can go all day. My charge controller max out at 15 amps current. Yes i could switch the charge controller to the 200ah battery, but thats to much of a hassle for a power outage a handful of times a year. Seems silly but it worked great.Thoughts?
