12kW 30.7kWh Three Phase All-in-One Energy Storage System with LiFePO4 Battery EH-46
The EH-46 ESS LV 12KW+30KWH is an integrated inverter and battery energy storage system designed for three-phase solar energy applications. Combining a 12kW rated AC output with 30.7kWh of rated battery energy, it provides an integrated solution for solar power conversion, battery storage and energy management.
With a maximum PV DC input power of 15.6kW and two MPPT trackers, the system supports solar integration across suitable PV configurations. Its 51.2V battery system provides 27.6kWh of usable energy at 90% depth of discharge, according to the product datasheet.
Integrated Inverter and Battery Design
The all-in-one architecture integrates inverter and battery functions into one system, simplifying equipment coordination and supporting a more streamlined installation compared with separately installed components.
Three-Phase AC Output
The system supports three-phase grid configurations with output options listed as 220/380Vac and 230/400Vac at 50/60Hz. This makes it suitable for compatible three-phase solar and energy storage installations.
High PV Input Capability
With a maximum PV DC input power of 15,600W, an 800V maximum PV open-circuit voltage and two MPPT trackers, the EH-46 supports solar integration for appropriately designed PV arrays.
Parallel Operation and Energy Management
The datasheet states that up to 12 units can operate in parallel. It also supports configuration of up to six charging time periods and cutoff thresholds, helping installers tailor system operation to project requirements.
Intelligent Air Cooling
The integrated intelligent air-cooling system is designed to manage operating temperatures. The datasheet specifies an operating temperature range of -20°C to 50°C and acoustic noise below 50dB.
Monitoring and Remote Connectivity
Wi-Fi and APP monitoring are listed as standard monitoring options in the datasheet. An optional 4G/GPRS module is available for remote connectivity.
