[RE-wrenches] Is it OK to add EG4LL-S alongside Fortress e-Vault Classic?

[Mick Abraham]

Hi, Wrenchies~ I sold one E-Vault Classic cabinet to an off-gridder in 2021
(18.5 kWh rated). He set it up open loop even though he's got Schneider XW
Pro. Now he'd like more storage and asked for a quote on one EG4LL-S
cabinet, fully loaded (30.7 kWh).

Surely he would have to stay open loop if these two brands are combined.
Both brands have 16 cells in series = 51.2 nominal volts. However, EG4
documentation calls for 56.2 volts Bulk & Fortress calls for 54.4 volts
Bulk.

War stories or suggestions welcomed; thanks in advance. The Wrench List is
the Bomb!
