Description
Scaling to 120 kWh with zero master controller upgrades.
GoodWe GW60KWH-D-10 Extension is a secondary 60 kWh commercial outdoor expansion cabinet housing twelve decentralized 5 kWh Lynx D modules, engineered to double the storage capacity of primary GW60KWH-D-10 stations to 120 kWh with plug-and-play linking.
Doubles System Capacity to 120 kWh
Expands the primary GW60KWH-D-10 battery station cleanly without complex electrical redesign.
Pre-Wired Decentralized Module Stacks
Houses twelve 5 kWh high-voltage modules with internal DC-DC converters for uniform power sharing.
Streamlined Inter-Cabinet Connectivity
Pre-fabricated power and communication linking harnesses ensure fast, error-free on-site expansion.
IP55 Outdoor Weatherproof Enclosure
Matches the exact footprint, aesthetic, and environmental durability of the primary cabinet.
More product details
Adding battery capacity to an operating commercial installation typically requires upgrading master BMS controllers and rebuilding distribution boards. This extension cabinet connects directly to the primary unit via pre-fabricated wiring harnesses.
- Pre-engineered DC linking cables connect directly to the primary cabinet’s internal expansion terminals.
- Direct CAN synchronization allows the primary controller to manage both cabinets as a unified 120 kWh bank.
- Eliminates complex on-site busbar fabrication and secondary switchgear engineering.

GoodWe GW60KWH-D-10 Extension (60 kWh expansion cabinet, requires a base unit)
Independent module-level power control across expanding battery banks.
Because each of the twelve 5 kWh modules inside the extension cabinet features its own bidirectional DC-DC converter, adding this cabinet years after the primary unit causes zero aging mismatch penalties. Parallel power stages regulate voltage independently, allowing seamless integration with older battery packs. Eliminates cross-cabinet circulating currents during high-rate charging and discharging. IP55 weatherproof enclosure certified for outdoor pad installations from -10 °C to +50 °C.
Adds eleven series packs on 633.6 V
Eleven 5.76 kWh packs operate between 554.4 and 712.8 V DC. Continuous charge and discharge currents reach 96 A.
Fits a narrower 808 mm cabinet body
The cabinet is 808 x 2050 x 1111.5 mm at about 972 kg. It is the expansion cabinet, not a standalone plant.
Talks to the base master over CAN
The internal BMS links directly to the base unit supervisory control. Up to two extension cabinets connect to one base.
Technical data
Seamless commercial storage expansion engineered for phased microgrid and peak shaving growth.
60 kWh plug-and-play extension cabinet to double commercial storage capacity.
Designed as the direct expansion enclosure for primary GW60KWH-D-10 systems, this extension cabinet adds 60 kWh of decentralized high-voltage storage. It links seamlessly via pre-engineered DC bus cables and CAN communication, scaling commercial energy storage up to 120+ kWh without extra master controllers or civil redesign.

GoodWe Lynx C 60 kWh datasheet, base and extension (EN) GoodWe Lynx C Series C&I Battery System 60kWh DatasheetProduct questions
Can this extension cabinet be used as a standalone battery system?
No. Requires a primary GW60KWH-D-10 cabinet. The GW60KWH-D-10 Extension cabinet is a secondary slave enclosure. It contains twelve decentralized battery modules and internal busbars, but relies on the master communication interface and control logic of the primary GW60KWH-D-10 cabinet to interface with the hybrid inverter.
What is the total combined capacity when linked with the primary cabinet?
120.0 kWh nominal / 114.0 kWh usable storage capacity. Linking the primary and extension cabinets creates a unified 120.0 kWh commercial battery system (114.0 kWh usable at 95% DoD), delivering full-day load shifting and extended facility backup.

Item number: DLK-GOODWE-GW60KWHD10
goodwe_lynx_c_60kwh_en.pdf p2 prints this cabinet as the Extension column against the base unit, and gives its parallel limit as 2 extension units per base unit. The extension carries no master section, 808 mm wide against the base's 1108, so it cannot be commissioned without one.
