5m power line A T58 BAT-BAT
The SolaX 5m Power Line A T58 BAT-BAT is the original positive power cable for cascading connection between SolaX Triple Power T-BAT H 5.8 (T58) battery modules. Length: 5 meters, pre-crimped terminals with quick locking. Essential for expanding the storage capacity of the T58 system when the batteries are installed at a greater distance than the supplied cables allow.
The SolaX 5m Power Line A T58 BAT-BAT is the original SolaX positive 5-meter power cable for daisy-chaining battery modules of the Triple Power T-BAT H 5.8 (T58) series. It is the component that carries high-voltage DC current from the positive terminal of one battery module to the positive terminal of the next, allowing you to expand the storage capacity up to the system’s maximum limit.
What is the Power Line A BAT-BAT for?
In multi-battery T58 configurations, the positive cable (Power Line A) connects the "+" terminal on the left side of an HV11550 module to the "+" terminal on the right side of the previous module, completing the DC series circuit. Together with Power Line B (negative), it forms the pair of power cables needed for each additional daisy-chain connection between modules.

When do you need the 5-meter cable instead of the standard one?
The cables included in the standard T58 kit cover short distances (typically up to 690 mm between adjacent modules). The 5-meter cable is needed when battery modules are installed on separate walls, when the wiring route requires conduits with bends, or when you want to ensure enough slack for future installations without having to redo the wiring. It must always be used together with the Power Line B (negative) of the same length.
Frequently Asked Questions
How many Power Line A BAT-BAT cables are needed to expand the T58 system?
You need one Power Line A (positive) cable for each additional daisy-chain connection between modules. In a master T58 + 3 HV11550 modules configuration (maximum for three-phase systems), you need 3 positive and 3 negative cables (Power Line B). Each connection always requires a pair: one positive cable (Power Line A) and one negative cable (Power Line B).
Can I use only the Power Line A without Power Line B?
No. DC wiring always requires both poles: positive (Power Line A, this product) and negative (Power Line B). They must be the same length to ensure equivalent resistance on both paths, avoiding imbalances in the storage system.
Is this BAT-BAT cable different from the BAT-INV (battery-inverter) cable?
Yes. The BAT-BAT cable (this product) is specific for daisy-chaining battery modules. The BAT-INV cable has different connectors and specifications, designed for connecting the master battery to the SolaX hybrid inverter. They are not interchangeable: always check the correct type based on the connection you need to make.
Is the Power Line A 5m cable compatible with HV11550 modules?
Yes. The Power Line A T58 BAT-BAT is compatible with the master T-BAT H 5.8 battery and with the HV11550 slave modules that make up the Triple Power system. The connectors are the same as those used in the cables included in the original kit, so mechanical and electrical compatibility is guaranteed.
Do I also need to purchase the communication cable (Comm Line) along with Power Line A?
Yes. For each additional connection between T58 modules, you need three accessories of the same length: the positive cable (Power Line A, this product), the negative cable (Power Line B), and the RS485 communication cable (Comm Line T58). All three must be installed together to ensure the correct operation of the storage system.
