About This Product

The ZYC SIMPO HV 28.8 + GW25K-ET combines a 28.8 kWh ZYC Energy SIMPO HV high-voltage battery system with the GoodWe GW25K-ET three-phase hybrid inverter. The battery stack uses nine 3.2 kWh SIMPO HV modules to provide 28.8 kWh of usable storage, while the GoodWe inverter manages solar generation, battery charging and discharging, grid interaction and backup operation. The combination is designed for larger residential and light-commercial three-phase installations requiring substantial storage capacity and high inverter output.

Who This Product Suits

The ZYC SIMPO HV 28.8 + GW25K-ET suits larger three-phase homes, workshops and light-commercial properties with high electricity consumption and substantial solar generation. Its 28.8 kWh battery capacity is useful for sites with heavy evening loads, air conditioning, pool equipment, EV charging, electric hot water or other significant electrical demand. The system is also well suited where backup capability, high solar self-consumption and modular battery storage are priorities.

Specifications Explained

The ZYC SIMPO HV 28.8 + GW25K-ET uses nine SIMPO HV 3.2 kWh lithium iron phosphate battery modules, giving 28.8 kWh of usable storage. In this configuration the battery operates at a nominal voltage of 576 V with an operating voltage range of approximately 540-657 V. The SIMPO HV platform supports up to 30 A continuous current and up to 45 A peak output for five seconds.

The battery stack is IP65 rated and uses CAN and Modbus RS485 communications. ZYC specifies a round-trip efficiency of approximately 96%, while the modular platform can be expanded further through parallel tower configurations where supported by the final system design.

The GoodWe GW25K-ET is a three-phase hybrid inverter with a 25 kW nominal power rating and a battery voltage range of 200-800 V. It supports up to 30 A continuous battery discharge current and high charging capability for compatible high-voltage battery systems. On the solar side, the inverter is designed for larger PV arrays and supports multiple MPPT trackers for installations with different roof orientations or array layouts.

Summary

The ZYC SIMPO HV 28.8 + GW25K-ET combines 28.8 kWh of modular LFP battery storage with a 25 kW GoodWe three-phase hybrid inverter. The nine-module SIMPO HV stack provides high-voltage operation, IP65 protection and scalable storage, while the GW25K-ET provides high-output solar conversion, battery integration and backup functionality. It is a practical combination for larger residential and light-commercial sites requiring substantial storage capacity and strong three-phase inverter performance.
