I currently have a retrofit Growatt. I want to add batteries to my 10KW solar system. I am using 25 x 350W solar panels (Seraphim I think). I am on old premium tariff so I may need to replace my solar panels and also the solar inverter. The solar inverter is not hybrid so I will need a hybrid solar inverter.
There is a manhole in our house and easy access to the roof. Our main electrical board is a single phase which is for residential. The aim of this is to start to slowly implement battery to our setup.
