Pylontech 2× US5000 9.6kWh 48V battery kit with brackets and inverter cables9.6kWh 48V LiFePO4 storage bank with stacking brackets and inverter cable set

Overview

Two US5000 modules with Pylontech stacking brackets and the inverter cable set give 9.6kWh nominal and 9.12kWh usable at 48V, ready for floor installation without a rack. The modules supply 100A continuous each, about 9.6kW together at nominal voltage, and the inverter usually sets the lower limit. The stack takes one more US5000 later, the maximum being three per bracket stack. One external cable pair carries 100A constant, so add a second pair for higher currents.

• US3000C: 3.55kWh, 37A recommended current
• US5000: 4.8kWh, 100A continuous current
• Up to 16 modules in one group
• CAN and RS485, automatic addressing in groups
• 19-inch rack or stacking brackets
• IP20, for indoor installation

• 2 × Pylontech US5000

How it works

Each US module is a self-contained 48V lithium iron phosphate battery with its own BMS, sized to fit a 19-inch rack. Modules are connected in parallel, never in series, so capacity and current add up while the voltage stays at 48V nominal. One group can hold up to 16 modules; several groups are linked over RS485 directly or over CAN through Pylontech's LV-Hub.

The first module in a group acts as master and talks to the inverter. Generations can be mixed: with a US5000 as master, US3000C or US2000C modules can follow in positions two to sixteen, and with a US3000C as master, older US3000 and US2000 units can occupy positions two to eight. Pylontech recommends using the newest unit of a type as master.

Key features

The US3000C stores 3.55kWh and handles 37A recommended, 74–89A for 60 seconds and up to 200A for 15 seconds. The US5000 stores 4.8kWh and delivers 100A continuous, 105–119A for 15 minutes and 120–200A for 15 seconds. Both allow 95% depth of discharge with inverters following Pylontech's current protocol, include soft-start for inverter inrush and dual active protection in the BMS, and accept firmware updates from the inverter via CAN or RS485.

Installation and compatibility

The modules are IP20 and belong in a dry, dust-free room between 0°C and 50°C, best at 10–40°C, at least 2m from heat sources and 0.5m from inverter air outlets, out of direct sun. They mount in a cabinet, a rack or Pylontech stacking brackets: up to four US3000C or three US5000 per bracket stack. Each external cable pair carries 100A constant, and a DC breaker of at least 60V, type C or D, is recommended.

Pylontech's low-voltage compatibility list includes the US5000 with Victron MultiPlus and Quattro via Venus OS, SMA Sunny Island, Studer Xtender, Schneider Conext XW Pro, Solis, Deye, GoodWe and many other 48V inverters, giving the communication type and verified firmware for each.
