I'm just fitting new Sharp 80W Solar Panels with MC (Multi Contact) connectors. These connectors cost a fair bit (need double adapters to arrange panels in parallel) and not likely to be easily replaced in the bush. My plan is to cut off the MC connectors at the panel end and replace with simple Anderson plug. Local a/elect supplier reckons that should be ok. Just wondering if anyone disagrees with that - don't want to make a mistake.
thanks in anticipation

jdwynn,
I use two panels and connect the rear panel to the front panel via a low voltage 12v plug, this is so I can remove one and put it out in the sun when I
camp (something I have *never* done to date) so I think an Anderson plug will do the same job.
The only difference is my 'female' plug is bolted and water-proofed direct to the back of the front panel, the rear (removable) panel has the 'male' plug which plugs into an extension cable back into the Solar system.

Can you attach the Anderson plug securely and 'safely' so it will not come loose, if you want to remove one or both solar panels to use them when your camped in the shade?

Howdy Mainey, it's been a long term project as you can see!!
I hadn't thought about fixing the Anderson plug just yet, but I can see no reason why it couldnt be connected to the frame I'm making for the panels. I don't really want to unbolt panels whilst on a trip, but who knows what the future holds - and plug has to be fixed somewhere.
cheers JD

Cut 'em off 'n throw them away.
MC are designed to be easy to connect and very difficult to disconnect. They were designed for easy installation of large solar installations where there are lots of connectors. They will drive you crazy in a RV application.
The best connectors are the anderson style power pole connectors. They are similar to one circuit of a normal anderson but only 15 or 30A.
15 A Power pole example
Don't use a standard
grey anderson as you may confuse it with the other andersons which are on the battery side of the reg. If you want to use the standard style get red ones which won't plug into the
grey ones to indicate that it is unregulated power.

I forgot to mention, there are about 4 - 5 main types of MC connectors, each look similar but they are slightly differrent and not compatible, depending on the panel manfacturer. You have to make sure you get the right one if you persist with them, which IMHO you shouldn't.

Power Poles are 15,30 and 45A in the small size housing and the 75A power poles use a 6GGE contact the same as can the 50A Anderson Plugs.
I use
grey Anderson Plugs for general connections and red Anderson Plugs for Solar for identification.

I purchased my last panel from Jaycar with this type of connector. Jaycar said the manufacturer would not honour warranty claims if I cut the connectors off.

Gee Rod, that's a good point. I'll think about it for sure, but honestly I wonder if manufacturers will honour the warranty in any case when panels are on a 4wd that goes bush regularly. Cheers

I would consider that is a salesman's statement from jaycar as its the panel performance that is warranted not the installation technique.
Jaycar is an importer of equipment and as such in the eyes of the law is the supplier and or pseudo manufacturer and that means its specifically relevent to them only.
I have personally seen many a Sharp panel installed with those plugs cut off with no consequence but then there hasnt been a claim of any kind either that I know of so that indicates good quality.
If anyone is worried about it you buy the smallest joiner lead and cut it in halves to give you a felame and male cponnector and then take off from the cut ends with your own leads and then you havnt interfered with the panel as such.

Warranties are a legal requirement - they can only get out if it, if they can prove that something you have done could have caused the problem.

Mike
Agreed 100% and normally with the original purchaser with no transfer so how many people stay in pwnership of anythong for 20 Plus years.
Ive seen people lose lifetime warrantee claims because they couldnt prove what the lifetime was and it was not specifically stated in writing.
With good solar panels the warrantee is a performance statement that the panel will still produce a percentage of its maximum rating after so many years cable or no cable.
