5m power line A T58 BAT-INV
The SolaX 5m Power Line A T58 BAT-INV is the original positive power cable for connecting the master battery SolaX Triple Power T-BAT H 5.8 (T58) to the hybrid inverter SolaX X1/X3-Hybrid. Length: 5 meters, pre-crimped terminals. Recommended when the battery and inverter are not installed next to each other.
The SolaX 5m Power Line A T58 BAT-INV is the original SolaX positive 5-meter power cable for connecting the master battery T-BAT H 5.8 (T58) to the SolaX X1-Hybrid or X3-Hybrid hybrid inverter. This cable carries high-voltage DC current from the positive terminal of the battery to the inverter's battery input connector, completing the DC power circuit of the storage system.
What is the Power Line A BAT-INV for?
The connection between the battery and inverter requires cables with connectors and cross-sections calibrated for the high DC currents of the T58 system (nominal voltage ~100V, max current 25A charging, 35A discharging). The Power Line A BAT-INV is specifically designed for this part of the circuit: it has different connectors compared to the BAT-BAT (battery-to-battery) cables and is not interchangeable with them. The 5-meter length is recommended when the master battery and inverter are not installed in the same rack or on the same wall.
Technical specifications

When is this 5-meter cable needed?
The standard cable supplied with the SolaX inverter for battery connection covers short distances. The 5-meter cable is needed when the inverter is installed in a separate room from the battery technical room, when the route includes ducts with bends, or when you want to allow for future relocation of the system. It should always be used together with the Power Line B BAT-INV (negative pole) of the same length.
Frequently Asked Questions
What is the difference between Power Line A BAT-INV and Power Line A BAT-BAT?
The Power Line A BAT-INV (this product) has connectors designed for the connection between the T58 master battery and the SolaX inverter battery connector. The Power Line A BAT-BAT, on the other hand, has connectors for connecting battery modules in cascade. They are not interchangeable: always check the correct application (BAT-INV or BAT-BAT) before purchasing.
Do I also need to purchase the negative cable (Power Line B BAT-INV)?
Yes, it is mandatory. The battery-inverter connection always requires both poles: positive (Power Line A BAT-INV, this product) and negative (Power Line B BAT-INV). They must be the same length to ensure equivalent resistance on both paths. Purchasing them as a 5-meter pair ensures uniformity and correct system operation.
Is this cable compatible with the X3-Hybrid three-phase inverter?
Yes. The Power Line A T58 BAT-INV is compatible with both single-phase (X1-Hybrid G4) and three-phase (X3-Hybrid G4) SolaX hybrid inverters, which use the same battery connection standard for T58 batteries. Always check the exact version of the inverter by consulting the SolaX technical documentation.
Can I use generic power cables for the SolaX battery-inverter connection?
No. SolaX uses proprietary connectors calibrated for the high DC currents of the T58 system and for compatibility with the integrated BMS. Using non-original cables can cause overheating, connection loss, BMS errors, and void the storage system warranty. Always use original SolaX accessories.
Is the inverter-side connector included with the cable or do I need to provide it separately?
The Power Line A BAT-INV cable is pre-assembled with original SolaX connectors on both ends: the battery side connector (T58 master positive pole) and the inverter side connector (SolaX battery input). No additional adapters or terminations are needed. Note: the inverter-side connector may in some cases be included in the inverter kit — please check before purchasing.
