Hi, as the sun has been out today and I have been isolated! I thought I would finally have a look at the solar panel set up on my day van. Without going into too much detail I have a renogy 100W solar suitcase panel with the built in 20Amp charge controller. This is portable as I think it's best to move the panel every couple of hours with the sun. Anyway, the battery and inverter stay in the van and I have a cable out through the roof that allows me to connect the panel when needed. These MC4 connections are a bit fiddly and I dont think are too robust so , My question is, can i remove the MC4 connectors and replace them with a single 16amp weatherproof socket ? As I think this is a much quicker and sturdier connection. Basically I would like the connections to be the same a the campsite hook up connections , but for my solar set up.
If I am reading you correctly then don't even think about it!
The whole idea of different types of plug and socket connectors is so that you cannot connect things that shouldn't be connected.
If you affix a 230v socket to a 12v system then it won't be long before someone puts 230v through with disastrous results.
If I have misunderstood your intentions then,sorry, otherwise leave things as they are.

If the problem with the MC4 connector is the fact that it locks and needs a tool to unlock, then my first thought would be 'disable' the locking mechanism.
Another vote for the Anderson. Also, oversolder the crimp connectors and reduce the cable length as far as you can, this reduces the volt drop in the system. Rotating the panel is not really required, face it south and you will get virtually all the benefit.
Is there an issue with the solar panel still generating if you unplug it from the battery or load. Does this cause a dangerous voltage to build up. Solution: cover the panel before connecting or disconnecting.
No, the voltage is fixed, 18v i think from the panel and the regulator output is controlled. If it is not connected it is open circuit so does not function. If you dont use the solar energy the panel just gets hot, like any dark surface in the sun.
Great response . Many thanks for the help. DaveS1 - I understand that , however if I was to use a female connection with the weathered flap surely nothing can plug into it only the male socket ? No campsite or 240V would be set up where the male end of the connections are live ? ( just asking not doubting for one second that this could happen even though that would be utter madness)
I like the look of this, thanks. I'll try get a picture of what I have done on my set up. Previous comment from DaveS1 has me doubting what I have done so I will most probably change it as he has given a good point.
Been doing some experiments with Anderson connectors, using my 25 watt Antex soldering did not work well for flood soldering, tried my gas blow torch but the flame was just to big, although did work well for flood soldering albeit a little over the top.
Have since bought a Dremel 2000 portable gas soldering iron, perfect for flood soldering Anderson connectors, £30 for the Dremel so not that expensive, and a definite good addition to my tool box, having never owned a gas soldering iron before.
Emergency purchase of the dual tip gas one, iron and flame, after trying and failing to solder the 13core cable with a standard iron, in the wind, when it was cold. I may have left the 13core a bit long when towing!
The flame tip is really good for high local heat for soldering bigger connectors.
