Someone has to be the first, so this is a picture of Fortress Power''s 1st eVault MAX installation site. 20 x 18.5 kwh batteries (3709 kwh total) communicating closed loop to the Schneider 9-stacked inverter wall.
Maintaining the communication line is the surprising challenge here. Special firmware is uploaded to accommodate so many devices sharing the same communication circuit.
Can you share more about why this was a challenge? Is this really significantly more devices than would be typically expected on, say, a microgrid or a VPP?
John, Tesla has been installing 100 Mwatt systems for over 5 years. They now sell the Mega pack for utilities. They don't seem to have any problem with new systems that are over a Giga watt . Why is the system you wrote about so different?
