Pylontech battery
The pack whose protocol half the industry cloned, which is why an inverter menu often lists Pylontech even when it has never seen one. Note the low 54 volt ceiling, well under the usual 58.4.

How many you need, by inverter
One pack accepts 74 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.
Manufacturer documentation names Victron MultiPlus-II 48/5000, Victron Quattro 48/10000, Victron MultiPlus-II 48/3000 for closed-loop operation with this pack.

Questions people actually ask
How many Pylontech US3000C packs do I need?
One pack accepts 74 amps and holds 3.55 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 4 of them to charge at full rate.
Does the Pylontech US3000C do closed loop communication?
It publishes CAN, RS485. Manufacturer documentation names Victron MultiPlus-II 48/5000, Victron Quattro 48/10000, Victron MultiPlus-II 48/3000 specifically.
How many can I wire in parallel?
The published limit is 16 units.
Which inverters pair cleanly with the Pylontech US3000C?
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.
