I decided to install the Ebox and not wait for the V5. I saved a lot of money, the warranty is the same and the batteries are locked up in a cabinet anyways out of sight. And installed in a closed locked cabinet attached to a system inverter whose application displays to me everything about the battery BMS anyways. So given the same price, great, but saving a few thousand dollars, I went dollar because i still need another 60 kW for the house to achieve the state of nirvana between me and my utility company. Maybe the next 60 kW ill be V5. Overall, I am happy with Pytes workmanship and documentation.
