As an after thought, the solar panel had a good 11 hours of sun yesterday and we moved the panel as the sun moved (we are in Western Australia) and it was 39 C yesterday and the sky was clear. After the sun set, the pump and light ran for about 3 hours and then stopped. This morning we had to press the start button to get the pump to start again. The charge light on the battery remains lit at all times as though it is charging, but doesn't go out at all so could it be that the battery is not charging properly? Thanks again.

Without knowing the wattage of the pump and those LED lights it will be hard to know if your battery is big enough to run your loads, but a 4.5Ah 12v battery will only get you about 15 watt hours which is not much at all.
IMO the battery is not big enough and that solar panel is also pretty small.Comment

Thanks very much for your response to my query, SunEagle.
