I have 2 questions regarding 12 volt to 240 volt pure sine inverters.
Because of the physical size of the 1000 watt inverter, my plan is to have it portable and only attach it to the batterries when needed. Our batteries are on the chassis below the 240 volt caravan supply point.
My first question is this.
Can we go from the 1000 watt inverter with a 3 metre 15 amp lead to the caravan 240 volt supply point?
Or do I run a 6 metre 10 amp lead direct to the washing machine from the inverter that draws roughly 300 watts when runnuing?
Second qestion is.
I use 50 amp anderson plugs for my 12 volt accessories, can I use 50 amp anderson plug for this 1000 watt inverter?
The inverter will be used only on sunny mornings to power the washing machine for a 25 minute cycle including filling with water when off the grid utilizing the 340 watts of solar and the 210 amps of batties plus the 105 amp in the back of the tow vehicle.

If you are going to run an inverter (or a genny) without earthing AC (true earthing, not negative DC) into your van then consider a RVD. Leads fitted with RVD and one of all for combos of 10/15amp plug/socket are available.
If you religiously limit your AC consumption and inverter draw to under 50amp then an Anderson will work. I use one on my 600watt. But if you want to be flexible, look at permanently mounting near your battery bank and use a suitably sized battery isolator switch.

[1]No,for several reasons
[a] you would need a lead with a different current rated plug [10A] to socket [15A]
Such leads cannot be purchased, as their use is not allowed by all States Electrical regulations
The van RCD, if fitted , would not be operational.
You would have more than one class 1 device [have 3pin plugs]connected at the same time For safety reasons only one Class1 device should be connected @ any time
[2] yes, that is the safest way
[3]That should not be a problem

Hi Dabbler.
Battery bank is on the chassis of the caravan just in front of the axles.
This is one of the reason for making it portable and being near the power supply point.
I we do own a RVD which will now travel us.
Thank you for the reply.

Hi oldtrack123. does that also go for things with 2 pin plugs, like phone chargers?
Is the safety concern with 3 pin items, to do with the fact that they might be higher powered items?

Hi Joe
You can safely use more than one item that are factory fitted with two pin plugs no matter what they are .
As the risk of shocks to earth is extremely low
But remember with those items you will still receive a shock if you make contact with both lines @the same time
The safety concern is when more than one item requiring an earth connection [always should have a 3pin plug] is connected @ the same time . If a combination of fault develops ,that can lead to an electrical shock between items &/or earth.
The safety recommendation is to never have more than one class1[ have 3pin plugs] connected at any time
The power draw of the item is not relevant as far as an electric shock is concerned

Thank you Oldtrack123 advice taken.
I am going to use 120 amp anderson plugs along with a suitable fuse on my 12 volt leads with a anderson plug fixed to the battery box alowing the inverter to remain portable and can be stored in a safe dry area in the caravan.
