Product description
Product description
The SolaX T-BAT-SYS-HV-S3.6 series is the manufacturer’s latest high-voltage (HV) modular energy storage system, specifically developed for the SolaX X1 and X3 hybrid inverters. The new generation offers higher energy density, easier installation and improved safety monitoring compared to the previous S2.5 series.
Available versions:
- SolaX T-BAT-SYS-HV-S3.6 – 10.8 kWh
- SolaX T-BAT-SYS-HV-S3.6 – 14.4 kWh
- SolaX T-BAT-SYS-HV-S3.6 – 18.0 kWh
- SolaX T-BAT-SYS-HV-S3.6 – 21.6 kWh
- SolaX T-BAT-SYS-HV-S3.6 – 25.2 kWh
- SolaX T-BAT-SYS-HV-S3.6 – 28.8 kWh
The system is based on 3.6 kWh LFP (lithium iron phosphate) cell modules, which are connected in series to form a high-voltage energy storage. A set can contain 3–8 modules, so the total energy storage capacity can be freely configured between 10.8 and 28.8 kWh. The system is monitored by the BMS-BOX-HV-S3.6 control module, which manages and balances the status of each battery module separately.
The S3.6 series offers higher output power and better thermal management than the previous generation. Active cell balancing ensures that each cell always operates at the same charge level, increasing the lifespan and safety of the entire system. The batteries are housed in an IP65 aluminum housing, making them suitable for both outdoor and indoor use.
The system's fanless, naturally cooled design ensures quiet operation and maintenance-free operation. The operating range from -10°C to +50°C and a lifespan of over 6000 cycles ensure long-term stability. The system is fully compatible with the SolaX Cloud online platform, which enables real-time energy monitoring, statistics and remote diagnostics.

How do I choose the right battery?
How do I choose the right battery?
The most important thing is that the battery fits your inverter and the performance of your system. It is worth considering how much capacity (kWh) you need and whether you want to expand the system later.
Always check the inverter's technical data sheet, as it will tell you which batteries it is compatible with. For example, Huawei inverters only work with Huawei batteries, while Deye inverters can be connected to multiple manufacturers, offering a more flexible solution.
How do inverter types differ?
How do inverter types differ?
The lifespan of modern lithium batteries is usually 10–15 years, depending on usage and temperature conditions.
Manufacturers typically give an expected lifespan of 6,000–8,000 charging cycles – this can mean up to a decade and a half, assuming one cycle per day.
What happens in the event of a power outage?
What happens in the event of a power outage?
If the inverter supports backup (stand-alone) operation, it will automatically switch to the battery during a power outage, so the most important consumers continue to operate.
It is important to know that if there is no backup function, the system will completely stop in the event of a power outage, even if the solar panels are producing. This is because most on-grid inverters cannot operate without mains voltage for safety reasons, so they cannot supply power or charge batteries.
What warranty does the battery have?
What warranty does the battery have?
Depending on the manufacturer, batteries come with a 5 or 10 year warranty, and for some models this is also tied to the number of cycles. We indicate the exact warranty period on each product page, so you can always see how long the manufacturer's warranty lasts before you buy.
What happens if the battery fails?
What happens if the battery fails?
If the battery is not working properly, it is a good idea to first have the problem diagnosed by a professional to rule out incorrect setup or installation. It is possible that the problem is not with the battery itself, but with a non-activated function or communication setting.
If it is proven that there is indeed a problem with the product, you should contact the manufacturer's or distributor's customer service, who will assist you in the troubleshooting process and the warranty administration process.
