The build

P says (bearing in mind I know nothing) he totally agrees with you Mark but adds there are systems available that automatically switch over to battery should there be a power cut, it's the system he's considering. It's called EPS mode (emergency power supply). SC ask your supplier about an inverter that does this. The grand plan if we can get it, is to have batteries that will charge during a sunny day but supply our leccy when the sun goes down. P wants a system that will do this automatically but still provide customer some control. Some power companies also have a reduced price electricity overnight which can be used to recharge your batteries Octopus call it Agile Tarriffs.

SC P says if you or Bob want to discuss anything with him feel free to call him, pm me.
