a question about solar and battery charging for cuppa

hey mate sorry to bother you .
Just a quick question . I just purchased my 240 watt panel with 20 amp controller stuck on back 3 80 watt panels portable .It came with 6mm cable they are bosch cells with a land star pwm controller I will probably upgrade the cable and controller later. I will be connecting via 50 amp Anderson plugs cable length is 7 metres
My question is, you know how the controller has load points do these need to be connected to your loads such as fridge for the controller to work properly re sensing that the battery is fully charged as load would be sensed by controller or is it ok to keep all my loads connected to battery when in use. loads are connected to battery via fuse box.
so solar to battery charging ,battery to fridge drawing amps will controller still work properly re go into float mode boost ect. ps did you sort the rattle out bloody things.
