Sounds like input values close to a string inverter.
I'd try an old SMA or similar.

Hello Wrenches,
A friend just purchased 4 ESS MA 1428K batteries from AEP surplus. He
got them really cheap. They are rated at 26.5 KWh with an operating
voltage of 453 to 706 VDC!
He would like to find a way to use the power from these batteries.
Does anyone have any suggestions?
Thanks,
A follow up on my most recent inspection. I was worried about the AHJ
requiring the extra ground rod just below the array.
I didn't install the ground rod ahead of the the inspection and expected
to argue against it, trying for Exception2.
I got signed off without having to install it.
