Sunsynk 5.12kWh GM5.1 Single Battery Unit for HV Series 5.12 kWh GM5.1 LFP battery module for building a Sunsynk High Voltage Series rack-mounted battery system. Connects in series with other GM5.1 modules to create systems from 15.36 kWh to 61.44 kWh nominal capacity. Designed for use with the required high-voltage control box and compatible external PCS or inverter. Sunsynk GM5.1 5.12kWh high-voltage battery module The Sunsynk GM5.1 is a 5.12 kWh lithium iron phosphate (LFP) battery module used as the building block for Sunsynk High Voltage Series energy-storage systems. Each 51.2 V, 100 Ah module is installed in a rack and connected in series with a minimum of three and up to twelve modules, depending on the required system voltage and capacity. This is a component battery module rather than a complete operating battery system. It requires a compatible Sunsynk high-voltage control box, rack, cabling and suitably matched PCS or inverter. Installation and commissioning must be completed by a trusted, qualified partner. [file:95][web:96] Key features Modular system building block: 5.12 kWh per module, supporting stacks of 3 to 12 modules. LFP battery chemistry: lithium iron phosphate cell chemistry for high-voltage energy-storage systems. Expandable capacity: create nominal system capacities from 15.36 kWh with three modules up to 61.44 kWh with twelve modules. High-voltage architecture: module nominal voltage of 51.2 V; system voltage depends on the number of modules connected in series. Designed for rack mounting: IP20 module enclosure for installation in the Sunsynk high-voltage rack system. Where to use Use Sunsynk GM5.1 battery modules to assemble a Sunsynk High Voltage Series energy-storage system for larger residential, agricultural, commercial and industrial solar PV or battery-storage applications. Typical uses include increasing solar self-consumption, time-of-use energy shifting and provision of stored energy within a correctly designed backup system. A single GM5.1 module cannot be used on its own as a complete battery bank. The system requires at least three modules in series, a high-voltage control box and compatible inverter or PCS equipment.
