Does anybody have any preference for type and manufacture of this product? We have just bought a Jayco Conquest Tour Edition Motorhome and did not realise that an inverter was not included and we now need to get one fitted. It is shortly going in for it's 3 months caravan service and does anybody know if Jayco will install one or do we need to get it fitted independently? We are new to the forum but experienced camper/tailer users who have decided to go 'up-market' with a motorhome.
I always leave my camping area cleaner than I found it.
Curious what you intend to use a 2000W inverter for? It will be woefully ineficient runing small loads, not to mention the massive current draw on 12V. A 2000W generator would be far better.
We already have a 2000W honda generator which you can't always use and we need 240v power to use our laptop etc relying on our batteries
Don't worry, Be Happy!
Live! Like someone left the gate open!!
For running the Laptop, I've just got an adaptor, that runs directly from the House [solar] Battery.
Don't need an inverter for that.

There are some losses to have the inverter running, but if the design is any good, they would be small.
Beyond those, the drain on the batteries will be determined by what you are running with the inverter (plus 10 to 20% for inefficiencies).
Only if you run big appliances will the battery drain be high.
We run a 1,300W PSW inverter and usually leave it turned on 24/7.
Buying an inverter that is bigger than you need is still a waste of money though.
Choose a good one with low standby power and a high efficiency. If those figures are not available, look elsewhere.

Solo on the road full time in a Hino 145A towing a trailer (the shed)
Bus is full 240v with all LiFePo4 batteries.
Now in Lake Illawarra to fit out new trailer.

When it comes to Inverters they are our "Silent Friend" And to clarify some confusion here, Regardless of the size of the inverter whether its a 300W or 5000W it will
1- Draw a small amount of power at standby (check each brand as some are good and bad)
2- The inverter will only pull power from the battery it needs (with an addition of extra "called efficiency" ) The lower the efficiency the more heat it produces to give you 240Volts.
In most cases you only need a small 8ZED Pure Sine Wave for running the laptop and phones, tablets etc. The most other application for buying a larger inverter such as a 600W unit is to run a Cpap machine such as resmed or Fischer and Paykel.
(We currently have the 8ZED-600S-12V-SE, runs the 42inch tv, dvd player, laptops and when cold an electric throw blanket)
We went and spoke with the lads at Performanceshop as they have the 8ZED range as well as Projecta and the hefty GSL. whats the difference you ask? Performance wise nothing, A few features such as a remote or extended warranty is what sees the difference in price,and not much.
So for all the new people considering Inverters here's a simple helping hand, Probably not the best idea to go larger that a 1000W Pure Sine inverter as you would have to invest greatly on solar panels and batteries to get the run time, For example 1000Watts divided by 12Volts = 83Amps , So... a 120aH battery will see a 1000W operation of just under an hour. More though during the day as the solar panel assists with charging whilst running, But during the night you are on your own.
Another method to charge is using a module called KBI, GSL make these and they isolate the battery from the start battery so you never get stranded. Not sure if i can put a link here, but to keep TGNF happy i wont, Any hoo its called a KBI100-12
Now back to a Cpap machine and humidifier which is approx 400Watts and "not continuous" will see 8~9 hours operation on the 80~120aH battery. Which is good really, Then during the morning the 200W solar panel charges this up , Or driving around during the day.
Most Lcd TV's and Vast Sat systems are quite efficient hence you can get away with the 600W Inverter, But if operating a Cpap then this is the rare occasion you would purchase a 1000W Inverter.
Generators are whats the best solution for, Hair drying, Microwaves, Air Conditioners and any other heating appliance. But ..... If you have the room and the $$$ then you can get a great 3000W installation + batteries, (bare in mind you are looking at approx a $3000~$4000 solution) You could get a top shelf quiet generator for this kind of $$$
For fast calulations here is a quick link, Sorry in advance if it gets removed
And last of all, Anyone buying a 300W 8ZED or any inverter to use in there car please note ! Most car cigarette sockets are fused at 10amp, So you can only get 120Watts for the inverter, Any more power above that needs a direct connection to the battery.
Also the closer the Inverter to the battery the less the voltage drop, Thicker and shorter is better.
