Electrical: DC AC Conversions - Efficiency
I am an Electricity Novice: Assumptions: Boon-docker - does not use shore power, uses Solar Panels and Batteries, or generator. Refrigerator does not have propane option...electric only, AC or DC. ...

Thanks for taking the time to edumacate me.
BFL13, I sent this before seeing your last post so all references to you below relate to your previous post.
See specs for Charger at bottom.
OK roadrunner and BFL13, that helps. I did not realize the "charge" going into the battery was at 12 volts. I understood the charge coming out of the battery was at 12Vin order to (A.) feed 12V outlets/receptacles and (B). feed the inverter to go through the conversion to AC to feed the devices/equipment needing AC. So you are saying the Honda Inverter generator is delivering 120V/13.3A/1596W to the charger which then changes that current to 12V, same wattage 1596 so the Amps convert to 112.4 per W=V*A and that is then delivered to the battery bank. Thats is great news, much better to add amp hours at a rate of 112/hr than 13.3/hr. I understand the power loss due to charger efficiency (87%) per spec= 97.7 Amp. Does the Power Factor correction of .95 then bring it down to 92.8 Amps being sent to the battery resulting in 92.8 Amp hours being added per hour of charging at this rate?
Roadrunner -I thought Lithium batteries took a big charge quickly. What is the specification I should look for on a battery that gives me some indication as to how much current a battery CAN draw in a hour. (I am aware that charge rate and duration is programed or tailored per battery mfg and type. I knew that was part of the function of the controller between the solar panels and the battery, does the charger that receives the AC from the Generator also get programed for a charge rate and duration cycle?) I had heard Lithium batteries charge up fast (relative to other chemistries) up to 80% of full and then the last 20% of charge is at a slower rate but that it does not hurt the Lithium battery at all to quick charge up to 80% and then quit and use the battery back down to 20% before charging again. Apparently Lead Acid NEED to be fully charged each cycle to keep them healthy.
BFL13 - in your last sentence above, are you saying with a PF corrected Charger, the Honda Generator could possibly run on Eco mode and still deliver enough energy to the Charger for it to deliver 12V- 92.8 Amps to the battery bank? ...thus not needed to run at normal full power...1596 watts?
The Spec sheet for the Charger says the following:
125 ADC Continuous Output at 25 degrees Centigrade
87% Charger Efficiency
>.95 Power Factor
18 Input current at rated output (AC Amps)
