Hi Dave and All.
Reasons for HV batteries off grid?
1) Smaller cable size (I just did an 18 Kw off grid with 4 SIs and the
cable costs alone were in the order of $400) and increased flexibility
locating batteries and inverter. 10 AWG plug and play.
2) Higher efficiencies. Easy integration on the DC bus.
3) Integration with GTBB battery tech and systems. Why have two
standards and two sets of equipment? The line between Off Grid and

4). Integration with Electric Vehicles as storage for either GTBB or
Off-Grid - can integrate on the DC bus seamlessly.
These are the reasons that seem obvious to me. I’d be surprised if the
