Have had solar pannels for a while now , and after getting a smart meter , we realised how much electric we were sending back to the grid even in winter.
Therefore we decided to splash out and get a battery storage system fitted , its a 4.8Kw system that can have extra batterys fitted if we want.
Much to wifes annoyance Ive been monitering things over the last month and for most of the time we are running the house off solar/ battery power. even in the morning after running things like tv/ fridge/freezer lights ect all night the batterys are still at 40-50% capacity.
When I put the kettle on it used to draw around 3KW , but since the batterys were fitted its around 1-1.2kw we are pulling in from the grid (figures from smart meter display & the app that connects to the battery system). Im guessing the batterys can only be discharged at a certain rate , therefore with a 4.8kw system using 2 batterys , each battery will only give up about 1kw at a time.
Otherthing we are noticing is that the batterys are fully charged again by 2 or 3pm, after that we are just giving back to the grid
Thoughts are to add another battery or even 2 to the system so that we can be as indipendent as possible for electric , and not draw anything in from the grid for most of the year - guess the question is would adding more batterys give us this , or is the ammount that can be drawn from the batterys limited by what can go through the inverter
If it helps its an AC coupled system & a lux power system
