Easy Start By Micro Air
I wanted to run my 13.5 Dometic AC on my generator but having only a 2000 watt Honda EUI, it was either buy a bigger generator or try the Easy Start from Micro Air. I decided to go with the Easy St...

Air conditioner on 400a/h LiFePo4 - A follow-up
As per my previous (pg 3), once back at home I decided to do just a ‘table-top exercise’ using a higher estimated amperage draw at say 95+d/f ambient temp, so in this example I’m using 100 amps/dc for the air cond. (rather than previous actual of 8.5a)
(Note, equipment used on previous pg.)
Previous duty cycle (post initial 20-25 min cooldown) averaged around 50’ish % compressor run time (continuous low fan) - but for this example I’m using 60% duty cycle…
*********
Air Cond, 100amps @ 60% duty cycle (averaged) = 60amps per hour.
660w PV @ 60% harvest (reduced average estimate over time) = 400w…400w = 22amp (hourly gain).
Air 60a/hr (incl. duty cycle) minus 22a (hourly avg. harvest over time) = 38a/hr avg. hourly amp/hr deficit.
400a/hr LFP… Assuming start-up at 90% SOC = 360a/hr available at start of table-top test…
38a/hr hourly deficit @ 5 hrs run time = 190a/hrs battery provided…
360a/hrs at start, minus 190a/hrs consumed = end of run battery @ 42% SOC or 170a/hrs remaining.
The averages used were merely intended to reflect the vagaries of solar over 5hrs of mid-afternoon…
