High-Voltage Efficiency and Performance
The SolaX T58 Master battery was designed with high-voltage (HV) architecture in mind. HV systems, in contrast to conventional low-voltage systems, reduce energy loss during conversion, guaranteeing that a greater portion of the power generated by your panels actually reaches your appliances.
This HV solar battery has a 6000 cycle life and a nominal voltage of 115.2V, making it long-lasting. With a 6,000-cycle rating, you can anticipate nearly 15 to 20 years of dependable service even with daily charging and discharging. Because of this, the T58 Master is a long-term investment in the energy infrastructure of your house rather than merely a purchase.
Ultimate Compatibility: SolaX X1 Hybrid-Compatible Battery Storage
The “gold standard” combination for homeowners who already use SolaX inverters is the T58 Master. Designed to communicate natively with the X1-Hybrid and X3-Hybrid series, it is the best battery storage solution compatible with the SolaX X1 Hybrid.
-
Plug-and-Play Setup: No complex third-party configurations; the inverter and battery “handshake” instantly for rapid commissioning.
-
Smart Monitoring: Track your state of charge (SoC), temperature, and health in real time through the SolaX Cloud app.
-
Optimized Charging: The master unit’s integrated BMS ensures that cells are balanced perfectly, preventing overcharging and extending the system’s lifespan.
Scalability: A System That Grows With You
The modularity of the Triple Power series is one of its most attractive features. As your family’s energy needs grow, you can add up to three more “Slave” units (T58 Slave) to your initial SolaX T58 Master battery.
You can go from basic self-consumption to complete energy independence with this scalable high voltage solar battery with a 23kWh capacity. Your SolaX system can scale up to 23.2kWh of total storage without requiring the replacement of your original hardware, regardless of whether you plan to install a heat pump or add an electric vehicle (EV).
Uncompromising Safety: Safe LFP solar battery for indoor installation
When selecting a battery for your home, safety is the most crucial consideration. Lithium Iron Phosphate (LFP) chemistry, which is widely regarded as the safest lithium technology currently on the market, is used in the SolaX Triple Power.
Because it is cobalt-free and has excellent thermal stability, it is a safe LFP solar battery for indoor installation that essentially eliminates the possibility of thermal runaway.
-
IP65/IP66 Protection: Whether installed in a garage, a utility room, or even outdoors in protected areas, the T58 Master is dust-tight and protected against powerful water jets.
-
Operating Temperature Range: Engineered to perform in climates ranging from -10°C to 50°C, ensuring reliability in both winter and summer.
Technical Excellence
Beyond the numbers, compared to conventional batteries, the T58 Master offers a 90% Depth of Discharge (DoD), which means you can access more of the energy you store. Because of its small size and wall-mounted or floor-mounted design, it provides maximum power in the least amount of space.
