We don't roll like that , will be getting a new Kubota/Mecc alt genset , smallest they have and I feel comfortable with is 7kw unit, we had a 9.5kw
Also will be sizing this Solar setup to run a small deep freezer and led lighting
Hunting cabin with air conditioning, it's florida for God's sake

Thanks, no insurance , as its probably cost prohibitive due to the remote location, but never checked. No Physical injuries, just mental.
The a/c's pull 800 watts each, the freezer is manual defrost and is 100watts when running, everything else is how you described, diesel of course.
The smallest they make is a 7kva genset, sips .25 gph at 50% load. Thank goodness we have a few of us chipping in for the costLeave a comment:

New Twist on our solar install, The wildfires in the big cypress burned down our 9.5kw Kubota generator and lawnmower. Thankfully they caught it before our cabin caught fire but we still suffered a 10K loss.
I am now trying to re-size the new generator we will buy, thinking we should get a 7kw as the most we run is two 8000btu window units, deep freezer and a 1/4hp water pump

Not being intentionally dour, but if the fire had taken the cabin, you might have had an opportunity to rebuild a structure that wasn't as much of a heat sieve as what you apparently have now.
Finding ways and means of not using energy is almost always cheaper than getting more of it. Just sayin'.Leave a comment:

It is so good that is exactly what Telecom. military, and data centers use. In fact many FLA cells are Float Charged for 30 years and still going strong and capacity test confirm. However they use their batteries in a completely different application called Emergency Standby Float Service. Rectifiers hold the batteries at 54 volts on a 48 volt plant, and the rectifiers supply power to the loads. When and if there is an interruption in service, the batteries are already online and supply the power until commercial power is restored. After power is restored the batteries are Float Charged back to 100% SOC.
Another application everyone has sen, but unaware of is Emergency Egress Lighting, and Fire Alarm Control panels in every commercial building and commercial passenger airplanes. They work just like the telecom above, rectifiers (charger) Floats the batteries and supplies power under normal operation. If power fails the batteries are already online.
What makes it so kind and gentle is the Float Voltage is well below Gassing Voltage, and keeps the batteries at 100% SOC so no sulfate can build up. Where as 3-Stage charging requires an over charge voltage to speed the process up which is above Gassing Voltage. It stresses the batteries doing that. But with daily cycle applications you have no choice.

You guys are the Bomb, thanks for taking the time helping me figure this out
I read the manual and sure enough it says panel voltage should be 12-24 volts above battery volts for the best efficiency
I'm very exited to get this done, been wanting to a accomplish this for years
one other question, is it hard on the fla batteries to have them float charging for a couple weeks in between uses

68V is going to have a hard time doing a proper EQ in the winter (when you need it most) 75v (2 in series) should be fine,Leave a comment:

Thank you for the owners manual, I did not have that. Looking forward to reading that
I will have a 48v battery bank consisting of 8 batteries of the correct ah in series.
I read the info from their 2 page specification brochure dated 04/2017E
it stated peak efficiency was 68vdc input w/48v battery. (98.3%)
I read on page 102 of the owners manual that I'm probably over thinking this as the efficiency only drops to 95% even when 100v is charging a 24v bank.
I'm slightly concerned stringing my 3 panels (72 cell 325w) in series for a max Bmp of 112.8, Voc of 138. I dont think it will get cold enough here to push em over 150v. Maybe you experts can help decide
thanks as usual
dave

Thanks mike, the specs on the outback fm-60 state peak efficiency of 98.1% is at 68vdc input, the only drawback is a few more wire lenghtsLeave a comment:
