The SolaX TBMS-S51-8O is the system control and battery management unit designed for the SolaX Triple Power TSYS-HS51 high-voltage battery system using compatible 5.1kWh battery modules.
Installed as the control unit within the modular battery stack, the TBMS-S51-8O provides the interface required to manage and communicate with the TSYS-HS51 battery system. The SolaX datasheet identifies the BMS models as TBMS-S51-8 / TBMS-S51-8O.
The control unit is designed to operate as part of SolaX's modular TSYS-HS51 high-voltage battery platform.
The system uses 5.1kWh LFP battery modules and can be configured from 10.2kWh through to 66.5kWh depending on the number of battery modules installed.
Compatible battery models include:
TB-HS51
TB-HS51O optimiser version
5.1kWh capacity per battery module
Stackable battery architecture
Β
The TBMS-S51-8O forms the control layer of the TSYS-HS51 battery stack, allowing the battery system to communicate with the wider SolaX energy-storage system.
The TSYS-HS51 platform supports CAN and RS485 communications.
A single TSYS-HS51 system can be configured using multiple 5.1kWh battery modules.
The supported system configurations shown in the SolaX datasheet range from:
2 modules β 10.2kWh
3 modules β 15.3kWh
4 modules β 20.4kWh
5 modules β 25.6kWh
6 modules β 30.7kWh
7 modules β 35.8kWh
8 modules β 40.9kWh
9 modules β 46.0kWh
10 modules β 51.2kWh
11 modules β 56.3kWh
12 modules β 61.4kWh
13 modules β 66.5kWh
Β
SolaX's installation documentation also specifies one TBMS-S51 control unit in its standard TSYS-HS51 configurations. (SolaX Power)
The TSYS-HS51 battery platform supports:
60A rated operating current
Up to 70A maximum operating current
CAN + RS485 communication
Actual charging and discharging capability can vary according to the connected inverter, battery configuration, temperature and state of charge.
The wider TSYS-HS51 platform provides smart battery management functionality including remote fault diagnosis, upgrades and maintenance.
The TBMS control unit forms part of this integrated battery management architecture.
The TBMS-S51-8O is associated with the optimiser version of the TSYS-HS51 system. SolaX's datasheet separately identifies TBMS-S51-8 / TBMS-S51-8O BMS variants and TB-HS51 / TB-HS51O battery variants. (SolaX Power)
The optimiser-version system supports advanced functionality including:
Mixed use of new and existing batteries
Direct battery expansion
Rapid capacity expansion
Plug-and-play expansion
Rapid battery equalisation
Β
The TSYS-HS51 battery system is rated IP66 and designed for both indoor and outdoor installations.
This allows the control unit and compatible battery stack to form part of a robust floor-mounted energy-storage installation.

The TBMS-S51-8O is a battery system control/BMS component and does not provide 5.1kWh of battery storage by itself. Compatible TB-HS51/TB-HS51O battery modules are required to create a complete TSYS-HS51 battery system. The battery modules themselves provide 5.1kWh each.

Warranty Claim Process
In the unfortunate event that you encounter a faulty product, we want to make the warranty claim process as seamless as possible for you. To initiate a warranty claim, please follow these steps:
If damage is confirmed to be from normal wear-and-tear, drops, unauthorized repairs, or other non-warranty factors, service and shipping fees will apply. In such cases, we will contact the customer for approval before proceeding with paid repairs.
Unfortunately we cannot provide loaner units during the warranty repair process. For mission-critical equipment, we highly recommend purchasing backup units to prevent downtime in case of defects.
You have 30 calendar days to return an item from the date you received it.
To be eligible for a return:
Upon receiving your order, we kindly request that you thoroughly inspect all packages within 7 days of delivery. This inspection period is crucial as it allows you ample time to identify any visible damage caused during transit.

Should you identify any freight damage during the inspection, we urge you to notify us immediately. Our customer support team is ready to assist you through the claim filing process and provide the necessary guidance to ensure a smooth and hassle-free experience.
The advertised price for this product includes the applicable STC battery rebate, applied as a pre-discount at the time of purchase.
To be eligible for the battery rebate:
Supply-only purchases are not eligible for the battery rebate.
By proceeding with this purchase, the customer agrees to assign all eligible Small-scale Technology Certificates (STCs) associated with the battery installation to Solar Battery Supermarket (or its nominated agent).
This assignment allows the rebate to be applied as a point-of-sale discount.
If the customer does not agree to assign the STCs, the full non-rebated price of the battery system will apply.
Installation by a licensed and accredited installer is mandatory to qualify for the rebate-adjusted price.
Standard metro installation is available from $500, subject to property assessment.
Additional works (including switchboard upgrades, long cable runs, or non-standard installations) may incur extra charges and will be quoted and approved prior to installation.
To assess eligibility and proceed with installation, the customer may be required to provide:
