The Rhino asks for attention on one asymmetry: it will discharge harder than it will charge. A 200 amp discharge and a 100 amp charge limit means a system that empties this pack fast can then take twice as long to refill it, which is an availability problem on short winter days rather than a safety one.

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: BigBattery product manuals. 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 BigBattery Rhino 2 48V packs do I need?
One pack accepts 100 amps and holds 14.3 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 BigBattery Rhino 2 48V 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 8 units.
Which inverters pair cleanly with the BigBattery Rhino 2 48V?
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.
