August 11, 20214 yr I'm sorry to say but the documentation for the Hubble Lithium batteries is so bad! I'm looking for the correct info on which terminal to use when only a single battery is connected to an inverter. Can someone who knows, please confirm, the terminals marked in yellow are the correct one for a single battery? I'm just guessing at the moment based on their parallel connectivity diagram. And also, where is the ground/earth terminal on this battery?

You have 2 positives on a busbar and 2 negatives on a busbar.

There are lots of debate around whether batteries need to be earthed. I’m one of those that believe that they don’t need to however many believe that they do. Hubble has introduced a grounding terminal though on the battery.

Looks like I need to do a bit of research on the topic then. Do you happen to know where is that grounding terminal on the battery? It’s not marked anywhere I can see.

Well according to this guide: https://www.solaris-shop.com/blog/grounding-techniques-to-prevent-inverter-damage/ it shows the battery grounded as well. That’s why I thought, I need that. The battery can’t be an old model. Got it only couple of weeks ago and still busy mounting and connecting everything. Haven’t even switched it on yet. @87 Dream, those mounting bolts don’t even make contact with the chassis on the Hubble. There is a very thick layer of baked paint in between.

What I can say is that Hubble doesn’t need the battery to be earthed so you really don’t need to be concerned. I will however let you know tomorrow about the earthing point they have created for installers that want their batteries to be bonded to earth.
