Battery connections

Hi Hilary,

Anderson plugs are required for connecting high current stuff such as your 1500W inverter, but is it a semi permanent installation? If so a direct connection to the battery (via a fuse) is probably better. (Is 1500W a typo? It's a very big inverter just to run a tv and will be very inefficient. Suggest consider a 12V tv to run direct from the battery if it really is 1500W.)

If you have purchased a second battery of a similar type to your 80 Ah one, they can be connected together (positive to positive, negative to negative) to give you effectively a 200 Ah battery.

It's important to have a fuse right at the battery/s to protect the wiring, but not too sure why you want all the anderson plugs. Suggest you can probably share them if needed at all.

Can you daisy chain them or should each connect directly to the battery/s? I would ALWAYS use a fuse at the battery and from there feed individually to the plugs. Electrically either way is fine, but in practice daisy chaining is more difficult and will call for heavier wire.

Cheers

I've got a couple of serious questions here.

The whole inverter thing...yeh well there are less and less reasons to run inveters these days..and they are hell thirsty things.


all that aside.

you have a charger, and inverter and a solar pannel...um one socket would probably be enough for all 3...because its unlikly you will need any of those plugged in together.

You DO unplug your inverter when it isn't running.....hmmmm

I know lots of people use anderson plugs for light loads... but I don't think it is a good idea.

In my view, if you have a 50 amp anderson it should be able to deliver 50 amps, and have a 50 amp breaker or fuse in line.

If you connect a light load device with a light feed cable ( say 10 amp cable) to a 50 amps anderson that is capable of delivereing 50 amps......that light feed cable has no effective overload protection at all.

Conversely, if you have a 50 amps anderson that is not capable of delivering 50 amps safely, what happens when someone plugs a device that requires, more than the plug is wired for...Hmmmm

additionaly fitting light cable to a rediculously heavy plug is a silly game.




SO.....better to use a lighter format plug like a merit or one of the many other plugs available for things like ya LED lights.

now back to the original question..if you do want multiple andersons.....remember the plug will be rated at 50 amps....and good practice requires it is wired to deliver 50 amps...........

unless you are running very short cables and therfore can get away with light wire..ya wont get two adequate wires into an anderson terminal.

so ya far better off running back to some sort of terminal block to do your commons on...remember you need a fues or breaker in there somewhere


sorry but its oulds like ya need to think a bit more about ya whole DC power set up....and a properly built switch board is what you need.

cheers
