 The most common **higher end** portable generators are the [[http://amzn.to/2qVHopt|Honda EU2000-series]], inverter generator with [[http://amzn.to/2qnyZbI|Yamaha]] a close second.
-The **lower end** is dominated by [[http://amzn.to/2qqLGBJ|Champion]] and other open-frame, non-inverter "contractor" gennies, which are loud but cost 1/3rd as much as Japanese models.  Recently some inexpensive inverter generators have come to market, including the Harbor Freight Predator line.  Lower-end generators may not be intended for repair, and repair parts may not be available.

 Generators //are// well suited to charging [[electrical:12v:deep_cycle_battery#lithium_chemistries|lithium-chemistry batteries]] as that type can take current at all points of charging.
+If you are considering a genny for use with an inverter/charger combo, consider this:
+> Inverter chargers generally prefer conventional generator and not inverter generators. This is because they control the amount of power they pull from the generator just adjusting your island frequency. Inverter generators do not handle an external actor trying to adjust the frequency and will rigidly keep 50 or 60Hz until they trip. -- therealrimwarren((https://www.reddit.com/r/SolarDIY/comments/tv41bj/options_for_generator_on_an_off_grid_system/i381dv2/))
 ===== efficient use =====
 Generators generally have a minimum amount of wattage they can produce.  This means that until you hit that minimum multiple loads can be run for "free", speaking in terms of fuel consumption.

   - start the generator in the morning when batteries are most depleted and can take the most current
   - use your heavy loads at the same time as possible, up to the practical limit of the generator
-  - shut the genny down after the battery bank reaches Vabs and let solar handle Absorption and Float stages
+  - shut the genny down after the battery bank reaches Vabs and let solar handle Absorption and Float stages((Lithium banks may be efficiently charged by generator alone).
