Adding additional battery to PV system - REC required?

Archer Hack

Hi folks,

I have a PV setup with 5KW inverter and a single 3.6kwhr pylontech.

I want to either:

1. Add an additional compatable pylontech
2. Go down the DIY battery route replacing existing pylontech.

In either scenario: Does this fall under "minor electrical work" by electricity regulations (i.e. allowable to DIY)? Or does it require a REC (Registered electrical contractor) to perform the work?

I find it hard to find a clear definition in the safeelectric guidelines - can anyone point me to any supporting documents for guidance so i can validate my own assumptions?

If i am trying to get a REC to do the work - is there specific certifications they need/require to work on battery/solar systems?

Thanks

1. I highly doubt it, it's just a few cables to be adjusted, a matter of minutes
2. You will not find a RECI to perform this work, it's DIY

That wouldn't fall under restricted electrical works. No Rec required.

Thanks folks.

Yeah, the closest match on safeelectric i could see for 1. is "minor electrical work" which would not appear to require RECI. Thanks for the opinions on it.

That's good to know also that you're unlikely to get a RECI to touch a DIY setup.
