[QUOTE="sjroberts, post: 543570, member: 36464"] Hi. i have a 10kw solar array split through 2 inverters. Each inverter has a Growatt 6.5kw battery. We use no oil or gas, all our energy is electric, gshp for heating and hot water, electric hobs and oven. It’s the beginning of April and we are charging both batteries and using appliances and still have more power that we could be utilising. I think i could probably charge another 2 batteries from this time of year onwards. Now onto the question. At present the battery storage is lasting till about 02:00 so i would need another 5 hours or so of battery storage to not pull anything from the grid. I know the dark hours are getting less and the days are warming up so the heating will be used less but im struggling to make the decision on if the extra batteries are worth the investment. Advice and opinions please [/QUOTE]
