jeff cote here with boatingtechtalk.com  so we have a fellow question from a  boater  named torsten and torsten uh is asking a  question  in response to our nespresso  video that we posted a few weeks ago so  jeff  following up on your nespresso uh  segment on the 27th of january  2021 what do you stand on the question  of combined inverter chargers versus  dedicated inverters  dedicated chargers pros and cons of each  um  and what's your thought on redundancy  you're right you know um  most of us as boaters are most likely  going to have  a combined unit inverter charger you  know  the reality is that the cost of buying a  high  output charger that is 100 amps  um is almost the same price as buying an  inverter charger with a 2000 watt  inverter and 100  amp charger so first off the bat if  you're gonna go dedicated inverter  dedicated charger  you're going to pay twice for it not  only you're going to pay for two items  literally double the price but the other  thing too that you're going to end up  doing is you're going to have to install  two devices  so that's two ac feeds going in one ac  feed even leaving  you're going to have connections dc  connections from the battery bank to the  inverter you're also going to have  dc connections from the battery bank to  the charger so we're talking about a  duplication of effort now that being  said  if money is not a huge object certainly  i like it right and i've seen that on  some boats where they're going to have  standalone inverters  stand-alone chargers good for redundancy  but another way to achieve redundancy  which is our more popular approach is  actually installing two inverter  chargers the reason we do that is from a  capital cost perspective it's  almost similar to buying a dedicated  standalone inverter  and a dedicated standalone charger so  from a capital cost perspective it's not  the same but it's similar  and if you lose one you still have the  other  right and that's the beauty of an  inverter charger especially for the  boaters and we've been doing this quite  a lot lately  installing two of them side by side so  you can  make use of certain things right you can  start stacking inverters so you could  have two 2000 watt inverters or two 3000  watt inverters and literally have both  of them working  together so now you have a 6000 watt  inverter  and have both chargers working at the  same time some boats have huge battery  banks as we know  i'm a big fan of sizing a battery bank  charger to the battery bank size right  so having two inverter chargers that are  both let's say outputting 150 amps at 12  volts  right that's maybe a 6000 watt inverter  300 amp charge rate and those two  combined  are going to really allow you especially  when you're running your generator to  recharge the batteries at a really  really fast rate which is important to a  lot of power boaters that have or sail  boaters that have large boats large  battery banks and have a generator and  they want to  recharge as quickly as possible so my  take on torsion's question is  my pref my preference is to actually  install two inverter chargers  if an inverter is something you need  versus want then i think it's worthwhile  considering  having a secondary inverter onboard  because generally the people that have  inverters there's a subset of us  that their refrigeration for instance  only works on an inverter power like  they  have no dc connected to that fridge so  if they're not connected on short power  if they're not running the generator  then they need an inverter  and if they don't have an inverter then  they're stuck to being on shore power  24 7 or generator 24 7. so that's why  for those borders that have  ac refrigeration on board i'm a big  proponent of have actually redundant  inverter chargers  running in parallel and if one fails you  can isolate  and you can do that with a source  selector switch all of this doesn't  happen in the unit you do it around  but you'll see the big boats you know  around 50 55 60 65 foot  they're actually going to start building  that in so around the trawlers around 40  45 or people that are really going  remote  that want a high level redundancy um i'd  recommend  two inverter chargers over a dedicated  inverter dedicated charger  and that's a great question thanks for  asking  thanks for watching this video and we'll see you on  the next video
