Deye GB-SL

All-in-one home storage: a 5-20 kW three-phase hybrid inverter stacked on 8.18-24.54 kWh of high-voltage LiFePO4.

Models Covered: DEYE-GB-SL

Manufacturer: Ningbo Deye Technology Co., Ltd.

Application: 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.

Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in Yemen that is Public Electricity Corporation (PEC), Ministry of Electricity and Energy. Confirm the grid code, import requirements and any local certification with them, or with us, before you order.

Frequently Asked Questions

Is the DEYE GB-SL suitable for hot climates like the Gulf?

Yes. The GB-SL uses LiFePO4 chemistry with a BMS and thermal management designed to operate safely in the high ambient temperatures common across the Middle East and Africa.

What is the warranty period?

This battery comes with a 10-year warranty covering manufacturing defects and capacity retention.

Do I need a separate inverter?

No. The GB-SL is an all-in-one — the GB-S hybrid inverter is part of the tower and ships with it, from 5 kW up to 20 kW three-phase. The published weight and height include it: the 8.18 kWh tower is 1,100 mm and 137 kg, the 24.54 kWh tower is 1,980 mm and 293 kg.

How much storage can it hold?

Two to six GB-LM4.0 modules stack in series, each 4.09 kWh, giving 8.18, 12.27, 16.36, 20.45 or 24.54 kWh. The modules connect in series without cables, and each extra module adds 220 mm and 39 kg.
