I have an H1 series (G2) inverter with one EP6 Plus battery (5.76kwh), and I would like to increase the number of batteries to 2.
My question is, Do I need an HV connection box ?

Yes, a single battery doesn’t need one but if you add another you will need the junction box (then you can add a further 3 batteries to make 4 in total).

Yes the installation instructions provide a good level of detail.
