SolaX X1-Hybrid-3.7D+T58V3 Master+Slave

SolaX X1-Hybrid-D + T58V3 Master + Slave energy storage system 

The SolaX X1-Hybrid-D + T58V3 Master + Slave package is a single-phase, high-voltage hybrid inverter-based energy storage solution designed specifically for residential use. The system is designed to ensure efficient solar energy storage, increased self-consumption, and stable backup operation for properties connected to a single-phase grid. The storage capacity can be increased step by step by adding Slave batteries connected to the Master unit, allowing the system to be adapted to consumption needs at a later date.

Why is it important to highlight the X1-Hybrid-D 3/3.7/5/6/7.5 kW inverter versions? 

The package is available with 3, 3.7, 5, 6, and 7.5 kW versions of the X1-Hybrid-D inverter, allowing the system to be tailored precisely to the size and consumption profile of the household. For a smaller home with basic consumption, the 3 or 3.7 kW version may be sufficient, while for higher energy requirements, heat pumps or electric car charging, the 6 or 7.5 kW version provides adequate reserve capacity.

This scalability not only improves the efficiency of the system, but also helps to optimize the investment, as there is no need to start with an oversized inverter, while the possibility of later expansion remains.

What can the SolaX X1-Hybrid-D inverter do in practice?

The X1-Hybrid G4 is a single-phase hybrid inverter that can switch to backup mode with a fast switchover time of less than 10 ms. The system can provide up to 150% EPS power for a short period of time, enabling stable operation even during peak start-up loads. It supports PV oversizing, operates with high charging and discharging efficiency, and has a built-in shadow tracking function. 

IP65 protection allows for outdoor installation, and the two MPPTs provide flexible string configuration. The system is compatible with lithium-ion and lead-acid batteries, and can be combined with the high-voltage T58V3 system to create an efficient HV energy storage configuration.

How does the T58V3 Master + Slave battery system work?

The storage side is provided by the T-BAT H 5.8(H) V3 Master unit and the connected HV11550(H) V3 Slave modules. The system uses LiFePO4 (LFP) cell technology, which offers a long service life and high operational reliability. A depth of discharge of 95% and a service life of over 6000 cycles ensure that the storage system delivers stable performance over the long term.

The master-slave architecture allows for gradual capacity expansion. The modules have a capacity of 5.8 kWh and can be expanded in several steps up to 34.6 kWh within a cluster. 

This is particularly advantageous for households where consumption is likely to increase in the future, for example, if a heat pump or electric car is installed.

Who is this configuration recommended for?

The SolaX X1-Hybrid-D + T58V3 Master + Slave system is the ideal choice for single-phase residential properties where the goal is to maximize self-consumption, reduce grid exposure, and ensure backup operation. The range of inverters from 3 to 7.5 kW allows the system to be adapted to the needs of both smaller and larger family homes, while the capacity of the high-voltage battery system can be expanded later by adding Slave modules, allowing for flexible long-term planning.
