So I have a young lass currently staying in my granny flat out back on the farm. I said she could stay whilst she got herself sorted as she had the opportunity of a job in the town where I live. Anyway I have an electric hot water system in the flat that we switch on about half hour before wanting a shower and then switch it off as it draws a fair bit of power and we are on stand alone solar. Suited us as we've only previously used the flat for visitors that come to stay the weekend. I have a monitoring system on the solar so I can keep an eye on the battery level when I'm not home ( I can access it from anywhere ). Anyway come 5.30 pm I see it's chewing a heap of power from the grid and it's half hour until sundown ,so I messaged her and said did you forget to turn it off. No she says I switched it on so I could have a shower tonight. I explained to her when she started staying there a week ago that if she wanted a shower in the evening she would need to go over the house as it is on gas. Well last thing I needed was to finish work at 7 pm and come home and stuff around with a genset to get some power in my batteries so I don't run out of power overnight . Why don't people ever listen !!!! I also don't charge her rent or anything to stay there ,was just trying to do a kind thing so she could get on her feet . Very grumpy tonight and I don't like being grumpy.Sorry for the rant I'm just over people today.
