SolaX TP-HS36 HV Battery Module 3.6 kWh LiFePO4
The Solax Power TP-HS36 is a 3.6 kWh high-voltage battery module with LiFePO4 technology for residential and commercial photovoltaic storage systems. Charge/discharge current up to 50 A, IP65 protection rating, operating from -20 °C to +53 °C thanks to the integrated heater. Scalable from 7.3 to 47.9 kWh per single system, with over 6,000 cycles of service life. IEC 62619, CE, UN 38.3. certifications. Plug-and-play, can be installed by just one person.
The Solax Power TP-HS36 (T-BAT-SYS-HV-S3.6 system) is a high-voltage 3.6 kWh battery module with LiFePO4 cells, designed for photovoltaic energy storage in residential and commercial applications. Thanks to its stackable modular structure and plug-and-play design, it ensures flexibility, safety and ease of installation.
Why choose a high-voltage LiFePO4 battery?
High-voltage batteries such as the TP-HS36 offer higher system efficiency than low-voltage solutions: lower conversion losses, smaller cable cross-sections and native compatibility with modern hybrid inverters. LiFePO4 (lithium iron phosphate) technology provides extremely high thermal safety, no risk of thermal runaway and a significantly longer service life than traditional NMC chemistries.

System flexibility and scalability
The TP-HS36 is the base module of the T-BAT-SYS-HV-S3.6 system: it requires a minimum of 2 modules to operate and can be expanded up to 13 modules per tower (47.9 kWh). With two towers on the same Solax hybrid inverter you reach 93.6 kWh; with the TCBox-70 accessory up to 3 systems and 280 kWh — ideal for large commercial installations. The modules stack vertically with a plug-and-play system, so installation is quick and can be carried out by a single technician.
Integrated heating and Soft Start
The system integrates battery heating technology that ensures performance even at outdoor temperatures of -20 °C, making it suitable for alpine environments, unheated garages or industrial sites in cold areas. The Soft Start function protects batteries and inverter from power peaks at start-up, increasing the longevity of the whole system.
Compatibility with Solax hybrid inverters
The TP-HS36 is compatible with all Solax Power hybrid inverters in the X1 and X3 range (e.g. X1-HYB, X3-Hybrid, X3-Ultra). The maximum number of modules per tower and the number of towers depend on the inverter model. The BMU (model TBMS-MCS0800) and the Series Box are not included with the single module and must be purchased separately or as a complete system.
Frequently asked questions
Does the TP-HS36 work on its own or is an external BMS required?
The TP-HS36 module does not include an integrated BMS. For operation you must purchase the Battery Management Unit (BMU) model TBMS-MCS0800 separately and, for two-tower systems, the Series Box. The system needs a minimum of 2 modules to work.
How many modules can I connect?
Each tower supports 2 to 13 TP-HS36 modules, for 7.3 kWh to 47.9 kWh. With two towers on the same Solax hybrid inverter you reach 93.6 kWh; with the TCBox-70 accessory up to 3 towers and 280 kWh per battery input.
Is it suitable for outdoor installation in cold environments?
Yes. The system is IP65-rated (dust and water-jet resistant) and has an internal heating system that allows operation down to -20 °C. It suits both indoor installations (garages, technical rooms) and outdoor ones, even in alpine or particularly cold areas.
Is it compatible with inverters from other manufacturers?
The system is designed to work with Solax Power hybrid inverters (X1-HYB and X3-Hybrid lines, including X3-Ultra). Compatibility with other brands is not guaranteed by the manufacturer. Before purchasing, check the specifications of your inverter or contact our technical support.
What is the guaranteed service life?
The system is guaranteed for over 6,000 full charge/discharge cycles, with a 10-year product warranty. LiFePO4 chemistry offers superior stability compared with NMC cells, ensuring minimal capacity degradation over time and no overheating risk.
