X3-IES-12K
The Solax X3-IES-12K is a 12 kW three-phase integrated energy storage system (ESS). It combines a hybrid inverter, BMS, and expandable plug-and-play LiFePO4 batteries up to 30 kWh in a single design. Features include IP66 protection, 200% PV oversizing, micro-grid function, and a 10-year warranty.
The Solax X3-IES-12K is a 12 kW three-phase integrated energy storage system (ESS) from the X3-IES series by Solax Power. Like the entire IES line, it integrates the three-phase hybrid inverter, the BMS, and the LiFePO4 plug-and-play battery modules into a single compact structure, offering a complete photovoltaic storage solution that is simple to install.
X3-IES-12K: Power and Flexibility for Residential and C&I
The 12 kW model is positioned between the 10K and 15K, covering large residential systems and small commercial applications with medium-high energy needs. With 2 MPPT, a maximum DC voltage of 1000 V, and a maximum current of 20 A per MPPT, it supports the latest high-power panels. The 200% oversizing allows for a PV generator up to 24 kWp, optimizing the production profile and battery charging throughout the entire solar day.

AI Management and Micro-grid
Like all X3-IES systems, the 12K integrates predictive energy management with AI, which optimizes charge/discharge cycles based on consumption patterns, PV production forecasts, and energy tariffs. The micro-grid function allows the system to simulate the grid and keep string inverters active in the absence of the public grid. Up to 10 units in parallel for installations with higher storage capacity.
Frequently Asked Questions
What is the difference between X3-IES-10K, 12K, and 15K?
The three models share the same mechanical structure, the same TP-HS50E batteries, and the same technological features. The difference is in the nominal output power: 10 kW, 12 kW, and 15 kW respectively. The choice depends on the size of the PV system, the user's energy needs, and the connection limits imposed by the local distributor.
Is the X3-IES-12K suitable for a farm?
Yes, the X3-IES-12K is suitable for small and medium-sized farms with a three-phase contract. The intelligent load management supports integration with heat pumps and EV charging stations, which are typical in modern agricultural settings. Multiple units can be installed in parallel to meet higher energy needs.
Is the TBMS-MCS0800 necessary for the X3-IES-12K system?
No. The TBMS-MCS0800 is the BMS (Battery Management System) for the T-BAT HV storage systems, compatible with the X3-Hybrid G4. The X3-IES has its own BMS integrated into the structure, specific for the TP-HS50E batteries of the IES series. The two systems are separate and not interchangeable.
Are the TP-HS50E batteries of the X3-IES compatible with cold temperatures?
Yes, the X3-IES system integrates a battery heating system that allows operation down to -30°C. This feature is essential for installations in unheated environments (garages, warehouses, alpine areas) where standard batteries could suffer a significant reduction in available capacity.
How many systems can be monitored remotely with the X3-IES-12K?
Monitoring is done via the Solax Cloud platform, accessible from the app and web portal. A single account can monitor all associated systems. For multi-inverter parallel installations, the platform provides an aggregated view of production, battery status, and consumption for the entire installation.
