Pylontech H48050 PowerCube-X1 battery module 2.4kWh2.4kWh 48V LFP rack module for PowerCube-X1-V2 strings

Overview

The H48050 is the 2.4kWh, 48V, 50Ah lithium iron phosphate module of the PowerCube-X1 system. It is designed for series connection under an SC0500 controller, not as a standalone 48V battery: each module adds 48V and 2.4kWh to the string, which runs from two to ten modules, 96–480V. The 19-inch module is 442×390×100mm, weighs 24kg and has two pairs of power terminals plus Link ports to the controller. It is the right part for extending or servicing an existing PowerCube-X1-V2 string.

• 2.4kWh, 48V, 50Ah H48050 modules in 19-inch format
• 2–10 modules per string: 4.8–24kWh, 96–480V
• SC0500-40S-V2 controller: 25A nominal, 37A maximum
• Modbus RTU, CAN and LAN, plus Wi-Fi and USB
• Up to 6 strings in parallel over CAN
• IP20 modules for indoor restricted-access rooms

How it works

PowerCube-X1-V2 is a high-voltage system in which H48050 modules of 48V and 2.4kWh are wired in series and supervised by an SC0500 V2 controller. A string holds two to ten modules, giving 4.8kWh at 96V up to 24kWh at 480V, with the voltage stepping in 48V increments. Modules and controller are 442mm wide and mount in a Pylontech rack of 600×505mm footprint.

Up to six strings can be paralleled over CAN without a separate master BMS. The controller set to address 1 acts as master and is the only one whose external interface talks to the inverter; where V1 and V2 controllers are mixed, a V2 controller must be the master.

Key features

With the SC0500-40S-V2 controller a string charges and discharges at 25A nominal and 37A maximum; the larger SC0500-100S-V2 raises the maximum to 50A. Efficiency is 96% at 0.5C and depth of discharge 95%. The controller has two dry-contact inputs and four outputs for stop charge, stop discharge, error and current limit, a 6-bit address switch with a built-in 120Ω termination, a USB port for updates and a Wi-Fi module for cloud access.

Installation and compatibility

Modules are IP20 and the rack IP00, so the system belongs indoors in a restricted-access area, and only authorised personnel may work on it. The rack is fixed to its base and to the wall with M10 screws. Pylontech gives 0°C to +50°C as the working range, ideally 18°C to 28°C, and asks for cooling or heating where the room leaves that range. The grounding resistance must not exceed 100mΩ.

Inverter compatibility must be confirmed for the exact model and firmware. Pylontech's high-voltage list notes that Deye hybrids need PowerCube-X/H-V2 controller firmware V1.2 or later, and that CE+T inverters work only with PowerCube X/H and X/H V2. Keep all modules in a string of the same type.

Monitoring and settings

The controller communicates with the power conversion system over CAN or Modbus RTU through its RJ45 ports and offers a LAN port for network access. Status LEDs show run, alarm and black-start states; holding the start button during self-check closes the relay for ten minutes so an inverter can start from the battery. A USB port handles firmware updates and data download, while the Wi-Fi module links the system to Pylontech's cloud platform.
