SOK built its reputation on serviceable packs: the case opens, the cells are named, and the BMS is replaceable. The narrower 46.4 to 56 volt window is the thing to check against your inverter, because a 58.4 volt absorption target set for a different battery will push this one into its own protection rather than into a full charge.

How many you need, by inverter
One pack accepts 100 amps. An inverter that can deliver more than that needs more than one, or the charge rate capped in settings. Both are valid, and the second one costs you charging speed on the short days when you need it most.
Communication
No document tracked here names a specific inverter for closed-loop operation with this pack. That does not mean it will not work. It means nobody has published the test.
Where the figures come from
Manufacturer documents: SOK product documentation. Figures here should be read against the revision that covers your serial number, because manufacturers revise specifications without changing the model name.

Questions people actually ask
How many SOK 48V 100Ah Server Rack packs do I need?
One pack accepts 100 amps and holds 5.12 kWh. Match the pack count to your inverter’s charge current first, then check the energy. A Sol-Ark 15K at 275 amps would take 3 of them to charge at full rate.
Does the SOK 48V 100Ah Server Rack do closed loop communication?
It publishes CAN, RS485. No document tracked here names a specific inverter, so any closed-loop claim needs confirming with both manufacturers before you rely on it.
How many can I wire in parallel?
The published limit is 16 units.
Which inverters pair cleanly with the SOK 48V 100Ah Server Rack?
None of the inverters tracked here clear all four checks with this pack. Most land on unverified because nobody has published the comms or surge figure, which is a gap rather than a fault.
