300 watt solar panel

Yes Roy the blue plug is on the chassis beside the battery box I’ve got a BM Pro battery management system installed

The Blue plug is possibly a 50 amp Anderson, not a lot of information supplied. Michael

Thanks Peter I’ll take that onboard and shop around

The "blue pug?" is a small Norwegian dog.

Yes, start a new sentence for every thought or topic, then we will know your intentions or questions.

I have a blue plug on the chassis next to the battery box the grey plug is not compatible with the blue hence the need for a blue plug on the lead from the solar panel I have a battery management system installed and it’s my understanding that this will monitor all the power inputs Granted you could be right with a 300 watt panel being to big so I’ll consider that in my thinking cheers

Ok, if Blue isn't compatible with a Grey, then I would change the Blue one, Mark it SOLAR INPUT, but having a normal Grey plug will enable any solar panel of "suitable specs" to be connected to your system as an AUX power source. OR buy a Blue and a GREY plug and have them connected to a short thick cable. that way it allows either a Blue source or a Grey source vie the two PLUG LEAD. My Jayco has what you describe but it is GREY in a BLACK enclosure and runs directly to the SOLAR input of the charger in van.

It is VERY important to know the AUX SOLAR INPUT VALUE of OPEN CIRCUIT VOLTS and MAX AMPS/ Generated so charger is not fried. It is best if you, or someone with a Multimeter can measure the PANEL Open Circuit VOLTS, IN FULL GOOD SUN and also the DIRECT SHORT CIRCUIT CURRENT it produces. Volts X amps = WATTS and that should be not more than the CHARGERS ability.
Does the Blue plug wiring go to the charger?
You need to know exactly what you have, and if possible, it's connections to CHARGERS and BATTERIES so problems are not created.

Thanks RMD yes the blue plug goes to the charger not sure of volts at this stage overcast day today so I’ll have a look at that later thanks

He has a blue Anderson plug, which is designed to go only with another blue Anderson plug, so it can be used only for the intended use (in this case, solar) and not be accidentally used for any other purpose. You are recommending he change the existing blue plug (on the vehicle) for a grey plug so it suits a panel he purchases. If he has to change a plug, why not simply change the panel plug nd retain the safety factor (apart from the fact it would be easier)?

Note: not addressing the voltage/amperage requirements here...

I originally had all Grey Anderson plugs.

Then had the bright idea to change to a Red connector on the cables from the solar panels to the regulators.

Damn nuisance as the different leads I had to connect other bits and pieces to power then required an adaptor.

So changed all back to grey and it is much simpler to hook up whatever to whatever.

Works for me.

Hi Craig S20,

Jaycar sell a few different types of Solar Panels, some Auto. Elec. also sell Panels, and ARB stores sell them.
