SolaX X3 Hybrid 8kW HV 3 phase + 11.6kWh HV Master+Slave ESS bundle

SolaX X3-Hybrid-D + T58V3 Master + Slave energy storage system

The SolaX X3-Hybrid-D + T58V3 Master + Slave package is an energy storage system based on a three-phase, high-voltage hybrid inverter, which is well suited for residential and small commercial use. The aim of the system is to use as much of the solar energy generated as possible locally and to manage the energy flow in a stable manner through storage, load management, and backup operation. The storage capacity can be increased step by step by adding Slave batteries connected to the Master unit, so that the system can be adapted to consumption requirements at a later date.

Why is it important to highlight the X3-Hybrid-D 5/6/8/10/12/15 kW inverter versions?

With this package, it is particularly important that the X3 hybrid inverter is available in 5, 6, 8, 10, 12, and 15 kW power versions, because this means that the system does not operate on a "one size fits all" logic, but can be tailored to the specific project consumption and planned PV size. In practice, this means better efficiency, more predictable backup behavior, and more flexible future expansion, especially where heat pumps, higher electrical loads, or electric car charging are involved.

What can the SolaX X3-Hybrid-D inverter do in everyday use?

The X3-Hybrid-D series is a three-phase hybrid inverter that can be used with asymmetrical loads and can switch to backup mode with a fast switchover time of less than 10 ms.

The system supports PV oversizing, charges and discharges the battery with high efficiency, and offers features that allow consumption to be adjusted to available production and storage capacity. Outdoor installation is supported by IP65 protection, allowing for flexible system placement.

How is the T58V3 Master + Slave battery system structured?

The storage side consists of the T-BAT H 5.8(H) V3 Master unit and the connected HV11550(H) V3 Slave modules.

The system is based on LiFePO4 (LFP) cell technology, which is a durable, safe, and long-cycle-life solution with more than 6,000 cycles at 95% DoD.

The essence of the Master-Slave structure is that the basic system can be expanded later by adding modules, so the storage capacity can be scaled along with changes in consumption.

How much can the system be expanded?

The modules have a capacity of 5.8 kWh and can be expanded in multiple stages in a cluster up to 34.6 kWh.

In practice, this means that the system is equally suitable for smaller, self-consumption-enhancing storage as well as larger configurations that support daily energy transfer and backup operation. Communication takes place via CAN and RS485 interfaces, which ensure a stable data connection between the BMS and the inverter.

Installation and environmental compliance

The storage unit can be installed indoors or outdoors, with IP66 protection, and can be mounted on a wall or floor.

The battery heating function available in the system helps ensure reliable operation even in low-temperature environments, which can be particularly important for outdoor installations.

Who is this package recommended for?

This configuration is the ideal choice for three-phase systems where increasing self-consumption, storage with gross settlement, conscious load control, and future expandability are important. The combination of the X3-Hybrid-D 5–15 kW inverter range and the T58V3 Master + Slave HV storage system provides a scalable foundation that can be used in both smaller and larger residential projects, as well as for smaller commercial applications.
