Description
Three-way current distribution for low-temperature operation.
GoodWe Lynx D 15 kWh is a 3-pack high-voltage storage system delivering 14.25 kWh of usable capacity across three decentralized modules, engineered to sustain domestic heat pumps and overnight EV top-offs with triple DC-DC redundancy.
Triple Independent DC-DC Architecture
Three decentralized power stages share current loads, reducing thermal stress under continuous high-draw cycles.
15.0 kWh Substantial Reserve Capacity
Sized to store ample daytime solar surplus from 12–15 kWp arrays, providing high overnight energy autonomy.
Direct High-Voltage Bus (320–480 V)
Connects straight to GoodWe three-phase hybrid inverters with peak electrical efficiency.
Multi-Year Future Expansion
Add a fourth or fifth 5 kWh pack at any future date without aging-mismatch capacity losses.
More product details
High-power continuous discharge generates thermal stress inside battery cells. By dividing the load across 3 independent DC-DC power stages, each Lynx D module operates at low current density, maintaining lower internal temperatures and extending cycle life.
- Three parallel power stages distribute household current draw evenly across all 15 kWh of LFP storage.
- Eliminates stack-level single points of failure. If one module is offline, the remaining two continue supplying 10 kWh.
- Direct CAN communication links all three modules synchronously to the GoodWe hybrid inverter.

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 3 packs (15 kWh) up to 8 packs (40 kWh) on the same DC bus. Floor-standing or wall-mounting brackets provide flexible layout options in residential garages and utility rooms. IP55 weatherproof enclosure certified for unheated basements, technical utility rooms, and sheltered outdoor alcoves.
Holds 156 kg on one floor plate
Three 52 kg bricks share one pedestal. The wall anchor steadies the mid tower.
Talks over CAN before the fourth brick
The three faces already report as one store. A fourth brick joins the same bank.
Stands one slot short of a full group
Four modules close a group. This mid tower already carries three of them.
Technical data
High-throughput decentralized storage engineered for heavy domestic electrification.
15 kWh three-pack storage built for homes with active heat pumps and EV charging.
Tripling high-voltage capacity to 15 kWh across 3 decentralized modules, this system delivers the power reserves needed for high-consumption households. It effortlessly handles high-current discharge cycles to run domestic heat pumps and top off electric vehicles overnight, while its triple independent DC-DC converters eliminate central controller failure bottlenecks.

Project fit
Where this model fits.
Scenarios that show which projects the GoodWe Lynx D 15 kWh (3 x LX D5.0-10) belongs in, what to verify before quoting, and when another model is the better pick.
Electrified Single-Family Residences with Active Heat Pumps (10–14 kWp PV)
Homes with 3-phase air-to-water heat pumps consuming 12–15 kWh overnight in winter, seeking high annual grid self-sufficiency.
14.25 kWh usable capacity provides the depth needed to sustain continuous compressor cycling and domestic baselines from 5 PM to 8 AM without grid purchases.

GoodWe Lynx D Series datasheet (EN) GoodWe Lynx-D Datasheet (EN)Product questions
Can I expand this 15 kWh system by adding a single 5 kWh pack 3 years from now?
Yes, with zero capacity penalty. Because each LX D5.0-10 module features its own internal bidirectional DC-DC converter, each pack's output is regulated independently. You can add a fourth 5 kWh module 3 years later without the new pack being throttled by the aging of the original three modules.
What is the total floor space required for the 3-pack Lynx D system?
Requires approx. 1.2 m of wall width or flexible floor stacking. Each pack measures 570 mm wide × 505 mm high × 175 mm deep (52 kg). The 3 packs can be wall-mounted side-by-side (approx. 1.8 m total width with clearances) or placed on floor-stacking brackets in a 3-high vertical column occupying just 570 × 175 mm of floor area.
