SolaX TB-HR140 battery pack 14.3kWh (HR140 rack system)14.3kWh 51.2V 280Ah LFP pack for X3-AELIO rack clusters

Overview

The TB-HR140 is the 14.3kWh pack of SolaX's HR140 commercial rack battery: 16 LFP cells of 280Ah in series at 51.2V, in a 115kg indoor housing. Seven to fourteen packs connect in series under one TBMS-R15 high-voltage box, building clusters of 100.1–200.2kWh at 358.4–716.8V for the X3-AELIO hybrid inverter. With two clusters on the inverter's two battery ports, one X3-AELIO can manage up to 400.4kWh.

• 14.3kWh, 51.2V, 280Ah LFP packs
• 7–14 packs per cluster: 100.1–200.2kWh
• 358.4–716.8V nominal cluster voltage
• Two clusters per X3-AELIO, up to 400.4kWh
• Indoor rack, IP20, natural cooling
• Over 6000 cycles at 90% depth of discharge

How it works

The HR140 is the indoor rack battery of SolaX's split commercial storage solution with the X3-AELIO hybrid inverter. A cluster consists of one TBMS-R15 high-voltage box (BMS) and seven to fourteen TB-HR140 packs connected in series in a rack. Each pack is a 1P16S string of 280Ah lithium iron phosphate cells at 51.2V and 14.3kWh, so a cluster runs from 358.4V and 100.1kWh (T-HR100.1) to 716.8V and 200.2kWh (T-HR200.2).

The X3-AELIO has two battery ports; with one cluster on each port SolaX quotes up to 400.4kWh per inverter. The TBMS-R15 operates between 250V and 1000V DC and communicates with the inverter over CAN, as do the packs with the BMS.

Key features

Usable energy is 90% of nominal, for example 180.2kWh of a 200.2kWh cluster. Rated charge and discharge power ranges from 50.2kW with seven packs to 100.4kW with fourteen, and SolaX states more than 6000 cycles at 90% depth of discharge and 95% round-trip efficiency. Charging works from 0°C to +53°C and discharging from -20°C to +53°C, with natural cooling.

The packs are rated IP20 for indoor installation at up to 3000m altitude and 5–85% humidity without condensation. The system is certified to IEC 62619, IEC 62477 and UN 38.3, and the X3-AELIO CEI 0-21 certificate includes the X3-AELIO-50K and 60K with the TB-HR140 storage system.

Installation and compatibility

A TB-HR140 pack weighs 115kg and the high-voltage box 37.5kg; the rack measures 576×2287×823mm and weighs 91kg empty. SolaX offers eight installation options, one with a single bracket and seven with dual brackets, depending on pack count. Packs connect to the high-voltage box with the supplied power and communication cables, and the rack must stand indoors, as the packs are rated IP20 only. Up to two clusters connect to one X3-AELIO through its two battery ports.
