I'm new here and I have a practical elecrician and technical background although now long retired. However I'm new to the use of a battery to harvest power from my domestic solar array. I've just had a growatt inverter and 6.5kWh battery installed (now that prices are becoming sensible!) and charge to 100% overnight from Midnight to 2:30 as I have Economy 7 with good night rates.
I also have an Air Source Heat pump for heating and hot water (the latter with a supplementary immersion heater for Legionella protection). my question is that I would like to run the hot water and heating during the latter part of the 7 hr period to take advantage of the low tariff, but I assume in my ignorance that the current draw will be from the battery and will drain it reducing it's effectiveness during the daytime, especially looking to autumn and winter low daily solar charging. Can I get around this by setting a second charging period for the battery forcing the power for heating etc to be drawn from the grid - or is that naive of me and should I use other methods to achieve my aim.
I'd really be grateful for any advice offered.
