Description
Four-channel load distribution with zero single points of failure.
GoodWe Lynx D 20 kWh is a 4-pack commercial-grade high-voltage storage system delivering 19.0 kWh of usable energy with 4-way decentralized DC-DC redundancy, engineered for large estates, multi-family homes, and small commercial workshops.
Quad Independent DC-DC Power Stages
Four decentralized power stages share continuous current loads, ensuring cooler operation and zero single points of failure.
19.0 kWh Heavy Commercial & Domestic Capacity
Ample energy storage to sustain multi-split heat pumps, commercial workshops, and all-electric households.
Direct High-Voltage Bus (320–480 V)
Connects straight to GoodWe ET 15–30 kW commercial hybrid inverters with peak electrical efficiency.
Zero Aging-Mismatch Penalty
Add a fifth or sixth 5 kWh module years later without dragging down total battery bank capacity.
More product details
Rather than routing all power through a single central master BMS, the Lynx D 20 kWh system divides the load across 4 independent DC-DC power stages. If one pack is taken offline for maintenance, the remaining three continue operating seamlessly.
- Four parallel power stages distribute commercial current draw evenly across all 20 kWh of LFP storage.
- Eliminates stack-level single points of failure, ensuring continuous facility power reliability.
- Direct CAN communication links all four modules synchronously to GoodWe hybrid inverters.

Expand capacity years later without replacing aged packs.
Traditional series battery stacks penalize owners who add modules after several years of use. Lynx D’s parallel DC-DC converters allow adding new 5 kWh bricks at any future point with 100% capacity utilization. Expandable from 4 packs (20 kWh) up to 8 packs (40 kWh) on the same DC bus. Floor-standing or wall-mounting brackets provide flexible layout options in mechanical rooms. IP55 weatherproof enclosure certified for unheated basements, technical utility rooms, and sheltered outdoor alcoves.
Holds 208 kg on one floor plate
Four 52 kg bricks fill one pedestal. The wall anchor steadies the full group.
Fits four IP66 faces on one pedestal
Hose water stays off all four faces. Discharge still runs at minus 20 C.
Talks over CAN as one full group
Four modules report as one store. The hybrid reads one finished bank.

Project fit
Where this model fits.
Scenarios that show which projects the GoodWe Lynx D 20 kWh (4 x LX D5.0-10) belongs in, what to verify before quoting, and when another model is the better pick.
Small Commercial Workshops & Agricultural Facilities (15–25 kWp Solar)
Small manufacturing facilities running daytime machinery, office air conditioning, and seeking to avoid expensive peak evening demand charges.
19.0 kWh usable capacity buffers midday solar overproduction, discharging at up to 20 kW to cover late-afternoon factory machinery runs without grid power.

GoodWe Lynx D Series datasheet (EN) GoodWe Lynx-D Datasheet (EN)Product questions
Can this 20 kWh system be paired with the GoodWe GW20K-ET commercial inverter?
Yes. An ideal 1:1 power-to-capacity pairing. The GW20K-ET commercial hybrid inverter features a 50 A high-voltage battery port. Pairing it with the Lynx D 20 kWh system provides 20 kW continuous DC charge and discharge throughput (1C equivalent), allowing the battery to be fully charged from solar in under 1 hour during peak generation.
How are the 4 modules installed physically?
Wall-mounted in a row or floor-stacked in two 2-high columns. * Wall-Mounted: Four 570 × 505 mm units side-by-side (requires approx. 2.4 m wall width). * Floor-Stacked: Arranged on floor-standing brackets as two neat side-by-side 2-module columns, occupying less than 0.6 m² total floor footprint.
