Load connecting MPTT controller

[wullie]

Now have my solar up and running,i am not sure what load connections are used for,could i connect up charging system for phones iPad etc ?

[Robbo]

They are not needed to be connected. You'll need to read the manual as depending on the controller they can be defined to do different things.

I use mine to power an outside light, it was just convenient to connect from the controller which has a handy switch for the load.

you said you have the solar up and running, so presumably the load connections are already connected to the batteries.

 

that is all you need to do.

 

EDIT:

just noticed Matty's comment.

I suppose it depends what type of MPPT controller the OP has, he hasn't told us.

my victron 75/15 has only 2 outgoing power terminals, marked 'batt', which in that case is the 'load'.

 

sorry if I confused the OP.

The load should NOT be connected to the batteries.

It is a function mainly designed for street lighting systems, timed use of power.

Yes, you can use this to charge stuff in the day when the sun is shining, and yes, a night light is good.

Depending on the model, the controller may have been designed for street lighting and it learns when it gets dark, and when it gets light and how long it is dark for by the panel voltage. It can then be programmed to turn on a light for a fixed number of hours either or both in the evening and in the morning etc.

Most people leave it disconnected.

My MPPT has the 'Load' connection. It is a 10A relay enabled when the Battery Voltage is GOOD, i.e. over 1.2v I think. I use it for powering a light as it is in a convenient place for that purpose.

Your connections should be +/- for Solar panel, +/- for Battery with an in-line fuse. The use of 'Load +/-' is optional but will have a limited power rating depending upon the rating of the internal relay.

... +/- for Battery with an in-line fuse.

 

And the fuse should be at the battery end of the cables but outside of the battery box.
