Deye GB-L Pro — Compact High-Voltage Battery System
A smaller-format, high-voltage stackable LiFePO4 platform (4 kWh per module) sized for residential and small-commercial hybrid systems.
Key Specifications
- Compact 4 kWh modules — 2 to 6 in series (8–24 kWh installed, 7.2–21.6 kWh usable)
- Right-sized for residential and small-commercial systems
- Dedicated GB-LBS-PRO BMS + GB-LBase mounting base
- Same LiFePO4 chemistry as the BOS-G Pro line — ~6,000 cycles at 90% DoD, 10-year warranty
The GB-LM4.0-PRO is Deye's newer-generation high-voltage battery module, built at a smaller 4 kWh, 102.4 V, 40 Ah unit size than the BOS-G Pro line — intentionally, since it targets residential and small-commercial installations that typically need 8–24 kWh rather than the 25.6 kWh-and-up stacks the BOS-G Pro platform is built for.
Modules stack from 2 up to 6 units in series, covering 8 kWh to 24 kWh installed — 7.2 to 21.6 kWh usable at 90% depth of discharge — from one product family, enough range to size a system closely to the actual household or small-business load, rather than rounding up to the next large fixed-capacity unit.
Like the BOS-G Pro line, each stack requires its own battery management unit — here the GB-LBS-PRO — and mounts onto a dedicated GB-LBase mounting base designed for the smaller module footprint, keeping the same design principle (cells + dedicated BMS + purpose-built mount) at a scale suited to smaller sites.
The chemistry and duty rating carry over from the BOS-G Pro platform — LiFePO4 cells rated for roughly 6,000 cycles at 90% depth of discharge with a 10-year warranty — so the choice between GB-L Pro and BOS-G Pro is primarily about system size, not a difference in underlying battery quality.
