Currently have a 3.6kw FIT system installed 10 years ago. I want to add a new Battery storage system with an extra 3kw solar and use a multiplus II(48/5000/75) setup for ESS. Setup so it does not affect the FIT system
Having scoured the forums i decided to approach National grid (western power) to discuss a DNO application. They have initially said " i dont think you can do a self install, please speak to a qualified installer"
My plan was to do all the infrastructure work and an electrician( (not MCS qualified) safety check and make the final connections and sign off the work for building regs.
Any advice how to proceed?
