 +==== inverters ====
 +
 +[[electrical:inverter|Inverters]] are used if/when you need to run 120vac((in the US)) loads from 12vdc((typically)) battery banks.  
 +
 +They will typically have a wattage rating labeled on them.  With more reputable manufacturers this will be the continuous duty rating.  With less-scrupulous manufacturers this might be the peak/surge output rating.  
 +
 +Unless the inverter says ''pure sine wave'' or ''PSW'' on it there is a reasonable chance it is Modified Square((or Sine)) Wave.  See link above.  
 +
 +
 +==== wiring and fusing ====
 +
 +While poking about taking stock of the components, also notice the wiring and fusing.  
 +
 +
 +It can be difficult to tell the construction and gauge of wiring by externals.  If you are lucky that information might be printed on the insulation of the wiring itself.  This kind of info might be printed only on one side maybe only every few inches or feet so it might be hidden at first.  Keep tracing and looking.  
 +
 +Fuses and breakers are usually labeled with their current limit 
 +
 +[[https://www.bluesea.com/support/articles/Circuit_Protection/1437/Part_1%3A_Choosing_the_Correct_Wire_Size_for_a_DC_Circuit|This Blue Sea article]] describes appropriate wire gauge for a given current and circuit length.
