hi youtubers jeff cote here with another  session of ask pys  so we've got a fellow boater john john's  got a  sailboat and he's got a freedom so  xantrex  freedom 20 modified sine wave inverter  charger  and with the heart interface panel i  recently watched your video where you  said you would never use a non-sine wave  inverter  i thought it was a good and reputable  inverter why would you recommend to  replace it  you're right i mean remember time  changes everything  right what was good one day is not good  later on so when this  xantrax inverter charger came out it was  awesome i mean here in the pacific  northwest there's literally thousands  upon thousands and thousands of boats  that have it  just locally it was the number one  inverter it was  really uh relatively affordable and who  doesn't want an inverter  most of us do not everyone but most of  us do and  they ended up having this xantrax  freedom inverter charger  the challenge is and by the way if you  see it on your boat it's probably got  this kind of  grayish color um  and it's got a distinctive pants panel  as well the challenge is it's modified  sine wave and what does modified sine  wave mean it's basically almost like a  square wave  you know and what that means is that  it's not a true sinusoidal wave that we  would have  when we connect to shore power or the  grid or a generator  or a modern true sine wave inverter and  that square wave  means that all most practically all but  most inductive loads and there's a big  distinction between  inductive and resistive loads what's a  resistive load a resistive load is a  toaster  a heater okay there's not a lot of  things that we use on ac anymore that  are resistive load a light bulb is a  resistive load right  inductive loads are what battery charger  vacuum nespresso machine blender  microwave uh tv  a lot of stuff is inductive the stuff  that we care about  are inductive and those inductive loads  hate  hate working on a square sine wave  they want a true sine wave case in point  i had a boater bought three nespressos  three never talked to the owner the  first time  bought in espresso tried it nespro so  didn't work  returned it bought another nespresso  didn't work  this time try the nespresso at home  third one worked brought it to the boat  stop working  then i got a call and sure enough what  was it this client was running an  espresso machine  inductive load on a square wave inverter  and so what we ended up doing is  literally removing the inverter and  changing it to a true sine wave so that  would be reason why you would want to  change that inverter from a square wave  to a true sine wave  but the other reason and i think that's  a reason unto itself that's also good  inverter chargers are pretty  sophisticated piece of equipment think  about it it's basically a computer  on your boat it's electronically it's  probably on the electrical side of your  boat is probably the most important  piece  of electrical equipment besides your  battery and it's complicated  it's a computer right this is not  trivial not at all  if you've got a piece of equipment that  not only provides an inverter but a  charger and it's 15 or 20 years old on  your boat  the question is how long are you going  to wait before changing it  and is it important to you right some of  us don't care for the inverter  but you might care for the charger and  in the summer we have this happen all  the time i  remind boaters inverters and chargers  don't die at the dock when they're not  being used they die when they're  actually being used when you're using  your boat  and in the summer sure enough i've got  technicians come up and on a monday  morning or tuesday morning i'm like  by the way you're getting on a float  plane you're going to the airport  here's the box and you're flying out to  a destination because this boater lost  their inverter charger and now they're  at the dock and their vacation stopped  without an inverter charger you're  really not going to have a fun trip  especially if you have one you're used  to having one so what i tell boaters i'm  like  don't wait till it fails to change it  because our vacations our time on the  water are pretty sacred  right we don't have enough time on the  water and the way to  get more time on the water is to have a  reliable experience with our electrical  systems  and a way to do that is if you have a  modified sine wave inverter on your boat  it's not that it wasn't good when it was  installed and things are better now  take the time change it out for a true  sine wave inverter  and then all those inductive loads that  i talked about like a blender a  nespresso machine a tv  your computer power tools  battery chargers all those things are  going to work really well with the true  sine wave inverter  do it for reliability and do it for  those loads  English (auto-generated)  Videolytics      Tools    View advanced
