I had this query elsewhere, but I think it might have been lost in historical thread.
hi Guys,
I have four queries:
1.
I am in the process of setting up my hideout off grid.
As we are 240v here in NZ, there is little use for the converter which is currently installed. I am in the process of pricing up 250W Solar panel and controller.
Here is what I plan to do.
Disconnect the converter output (+VCC and NEG on the picture) and remove the converter.
Disconnect the NEG and POS incoming supply from battery (Black and white wires on the picture) and put them into the controller for battery charge.
Run new wires from the controller output to NEG and POS on the picture.
Is this the correct method, or am I missing something? As I wont be using the +VCC but am guessing it is not necessary now.
I also am unsure if a 30A solar controller is suitable, in that any draw from the caravan will surely go through this controller (trailer is new, I have no idea of the potential draw). I could take the load direct from the batteries and ignore taking it from the controller?
2.
What are the 2 x 40A fuses for labelled Reverse Battery?
3.
If I fit an inverter, would I simply wire the DC to what will become two spare spaces on the POS and NEG. or do I put it across a fuse?
4.
I cannot find a DC isolator switch. It appears to me that the only way of total disconnect is removing a battery lug. If this is the case, I presume a simply isolator between the caravan POS and Solar controller will prevent batteries going flat when I am not there, and the solar is covered in snow/leaves etc..
The knowledge and comments are always welcome.
thanks
Carl
