The Pylontech US2000C is a LiFePO4 battery, composed of isolated lithium iron phosphate (LFP) cells. This Pylontech 48V battery has a long life, 6000 cycles to 90% discharge and a useful capacity of up to 95%, and is fitted with a Integrated BMS. It is also compatible with many brands of inverters, has a good price-performance ratio and a modular 19' rack format, allowing for easy scalability.
Thanks to its modular format, the Pylontech US2000C provides a easy scalability compared to other lithium batteries on the market. Pylontech batteries of different models can be connected, a feature not offered by all brands of lithium batteries.
The 2.4kwh Pylontech US2000C 48v lithium battery can be connected in parallel up to a maximum of 80 units. A maximum of 16 Pylontech battery modules can be connected in parallel, if you want to connect more, a Pylontech Hub port is required. With the Hub up to 80 Pylontech US2000C battery modules can be connected; up to 5 groups of 16 lithium battery modules each can be connected.
The US2000C incorporates multiple communications protocols that allow the charging parameters of this lithium battery to be shared and to function properly.
This pylontech US2000 battery is maintenance free. It is a sealed module and is intended for indoor installation. Avoid installing this 48v 2000w lithium battery in places where the temperature and humidity are very extreme.
The US2000C Pylontech has a built-in internal BMS, which distributes the power between the cells and prevents them from overcharging or over-discharging.
It is mandatory that whenever two or more US2000 Pylontech modules are installed in a rack or on brackets, to ensure the stability of the batteries and their proper ventilation.
Before installation, the mains must be disconnected and the battery must be checked to ensure that it is in the off mode. The polarity must be taken into account and the positive and negative cables must not be confused.
Pylontech batteries can only be connected in parallel, they do not allow series connection because the integrated BMS is for the battery voltage, in the case of the Pylontech US2000C battery it is 48V. The US2000C lithium battery must be grounded and the resistance must be less than 0.1Ω.
The following picture shows the front connections of the US2000C Pylontech:
The Pylontech LiFePO4 batteries have a modular 19′ rack format. These are the dimensions of the US2000C battery:
Power terminals
The battery has two pairs of negative and positive terminals, one for connecting the battery or the lithium battery bank to the installation and the other for connecting the Pylontech modules to each other.
Two 18 cm power cables, an 18 cm RJ45 communication cable and a 1 m long 6AWG earth cable are included with the battery. The power cables have self-locking connectors, it is necessary to hold down this locking button while removing the power plug. The picture below shows the cables that the US2000C Pylontech battery is fitted with.
Issues to consider before installing the US2000C
Pylontech US2000C 4.8kWh battery mount
Can be mounted vertically or horizontally. Cannot be installed sideways or with the front connections facing down. Modules cannot be stacked on top of each other, they must be placed with brackets (maximum 4 modules) or in a rack. The following pictures show the installation of the US2000C with brackets.
The picture below shows the mounting of the Pylontech US2000C lithium battery in a rack.
Switching on the batteries
Check all cables connecting the battery modules and the cables to the inverter. The disconnecting device between the battery and the inverter must be switched on.
Switching off the batteries
With the latest upgrade to the Pylontech C-model, the manufacturer allows up to 16 units to be connected in parallel in a single battery pack without the need for any additional accessories. If more Pylontech lithium battery modules are to be installed, a Pylontech LV-HUB Hub is required. If the connection to the inverter is via RS485, there is no need to use a Hub port, as the master batteries of each group will communicate with each other.
A maximum of 80 units of Pylontech US2000C 48V Lithium Battery 2.4kWh can be connected either by one type of connection or the other.
The combination of Victron + Pylontech can be used for the following systems:
It is mandatory to install a GX device: The BMS included in the US2000C battery communicates with this device. The minimum recommended firmware version for the GX device is v2.42.
All the Multi, Multiplus, MultiGrid and Quattro are supported. All VE.Bus inverters and inverter/chargers are compatible, provided that you use the appropriate model for the nominal voltage of the battery. They must be connected to the GX device via the VE.Bus connection port.
All the MPPT VE. Direct BlueSolar and SmartSolar are compatible. They must be connected to the GX device. If you want to use a VE.Can MPPT (2019 and later) the GX device must have more than one VE.Can port, as this is the port used for the connection to the battery.
Connections
GX device configuration
With a version v2.80 or later on the GX device, the DVCC settings will be set and applied automatically. In case it has to be done manually, these are the appropriate values:
Inverter configuration
Load configuration
VE.Direct MPPT configuration
The following adjustments must be made as a protective measure:
ESS system configuration
