8ZED 12v 2000W Pure Sine Wave Inverter
 


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.

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

Hi guys, I have to agree with DeBe. The 12 volt load current on your 12 volt system will be huge. Any standard 12 volt system would not cope with it. We run a 2kw Honda if we need 240 volts but mainly run everything on 12 volts and use Solar Panels to keep them charged but if the weather does not allow that then the Honda gets a run. For things like charging laptops, phones,etc you can buy 12 volts chargers for that role. Jaycar have a good range of suitable chargers for all of that. Trust that info helps. Brian

I run a pure sine wave inverter 300 watt. but know of others who have up around the 1000. If you have a generator for the majority of uses and just need the inverter for charging phones, laptops, cameras etc, that is plenty. Others might disagree but you have to remember if you are moving on every day or couple of days the house battery will keep charging.
I have had no problems so far.
Of course you can't run big items such as fridges or washing machines on it but you already have a genny so won't need that.
I got my inverter from Supercheap Auto. They are not that expensive.
Oh by the way, welcome to the forum.

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.

Cheers,

Sheba.

So true Sheba, it depends how you get the whole thing wired up. My S in L put a lead through behind my panelling into an area where he put in a power point and a 12 volt plug, so I can use either. (From the inverter) Also have a battery gauge so I can keep an eye on the levels and shut down if its getting too low. Travelling brings the battery back up again for next time.

 Not necessarily.

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.

 

Cheers,

Peter

I think 2000w is rather large if you plan to run only small items such as charge you computer etc.

In my old bus I ran a 500w and than ran most things including the washing machine, all lights and small appliances from this. My generator was only used for charging batteries when required. (has not been run for about 18 months so perhaps need to give her a run)

Check all the appliances you want to take and then do a list. You should find the load requirements on each appliances under the base.

I must admit I have a large inverter but I am all 240v so I use the power mine supplies. I run all appliances including the aircon and water heater but I have a system designed to handle the requirements.

Best to find your needs and then check what you will need. Add all the items together that could possibly run at one time and then perhaps double and that should be the max required if you are realistic.

If you need the hair dryer and the jug etc than you need to consider large gear but if just for lights and charging and perhaps the TV and Sat TV then your needs differ.

If possible make sure it is mounted close to the batteries as the losses in 12v are greater than 240v.

Hope this helps

Regards
Brian

Thank you to everyone who replied to our post. It made us realise that 'bigger' is not necessarily 'better'. We never intended to run any major items through an inverter as we do have a generator, 2 in-house batteries and a solar panel but I guess as 'newies' we wanted to make sure we had everything covered before heading off to do some major bush and free camping explorations, so thank you again for saving us a heap of money that would be more useful spent elsewhere and we will get some adapters that we can plug into the cigarette lighter for our mobiles and perhaps a 300w inverter...............On on (ex HHH)

Gibs all you need is to get that girl healthy and then work on your van and HIT THE ROAD.

Hope all is going well and you will soon have your batteries up and running and then off into the sunset YEEAHHH.

Regards
Brian

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.

Now ..

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 

http://performanceshop.com.au/what-power-inverter-will-i-need.html

 

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.
