+An //inverter charger// performs several functions:
+  - invert 12v battery power to 120vac
+  - pass-through shore power when available
+  - some can bond shore and battery power to support heavy 120vac loads
+  - charge battery banks like a [[electrical:converter|converter]]
+They tend to be [[https://amzn.to/2KMcImw|expensive]], some over $1000.
 ====== Sizing your inverter ======

 > The situation gets more complicated when there's a 3-prong 120 VAC plug.  The third prong is a safety ground which is assumed to be tied to a ground rod.
-> You can see that the neutral and ground wires [in shore power] are tied together at the panel.  That works, because the hot is 120 VAC.  You can also see how that is very different than two "half-hot" 60 VAC lines, and how that kind of tie-in would short out one leg of an inverter. \

 > In fact, the situation with an inverter is very similar to [a] 240 VAC circuit... which has 2 120 VAC lines driven 180 degrees out of phase, i.e., "push-pull."((http://thesurvivalpodcast.com/forum/index.php?topic=63891.msg758502#msg758502))
