Turn hot water to daytime heating

[Tereza]

I would like to heat our water during the day to take advantage of our solar. How do I turn off the “off peak” feature?

You should get a electrician and then get a timer put into your fuse box I have done this & it works effectively I have it come on at 11.30 am for around two hours 

You should use a qualified electrician for the job will save you money in the long term. I do run a 16 klw sonnen battery with my system
