Overview

The Deye GB-SL is an all-in-one residential storage tower — the GB-S hybrid inverter and a high-voltage battery stack in one floor-standing cabinet, with no battery cabling to run between them. The inverter is available from 5 kW to 20 kW, three-phase, with two MPPTs and up to 26 kW of PV; the stack takes two to six 4.09 kWh GB-LM4.0 modules in series for 8.18 to 24.54 kWh of storage at 179.2-691.2 V. Ten units run in parallel on-grid or off-grid, output is 100% unbalanced across the phases, and it will charge from a diesel generator.
