Deye Solar Batteries 4 kWh GB-L-PRO

A floor-standing high-voltage stack of 4 kWh, 102.4 V modules reaching 8 to 24 kWh, IP65-sealed with explosion relief and fire protection built in.

Models Covered: DEYE-GB-L-PRO

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: Power the house through the evening and sleep on the safety engineering. The Deye GB-L Pro stacks 4 kWh modules that each carry 102.4 V, so just two to six of them build a high-voltage system of 8 to 24 kWh, 7.2 to 21.6 kWh usable at the recommended 90% depth of discharge, sitting between 204.8 and 614.4 V nominal. Every module weighs 39 kg, and the finished tower occupies only 540 x 1530 x 385 mm of floor. Protection is layered: explosion relief and fire protection are engineered in, the IP65 enclosure keeps weather out, and an anti-corrosion grade above C2 suits salty coastal air. Charging is rated from -20 to 55 degrees C, current runs at 40 A with a 50 A, 120-second discharge peak, and an LCD reads out state of charge, power and total voltage. Firmware arrives as remote updates over CAN2.0 or RS485, certification spans CE, IEC 62619, VDE 2510-50 and UN38.3, and the warranty holds for 10 years. We are an authorised Deye distributor and supply the GB-L-PRO from our own stock, with technical support before and after the sale.

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 the UAE that rests with the local authorities (DEWA, ADDC, SEWA). Confirm the grid code, import requirements and any local certification with them, or with us, before you order.

Key Features & Technical Highlights

102.4 V in every module: Each 4 kWh module supplies 102.4 V, so two to six build 8 to 24 kWh at 204.8 to 614.4 V.
Explosion relief built in: Explosion relief and fire protection are part of the pack design, not accessories.
Skin graded for coasts: An anti-corrosion rating above C2 plus IP65 sealing stand up to humid, salty air.
Charges at -20 degrees C: Both charge and discharge are rated across the -20 to 55 degrees C range.
Updates without a visit: Remote firmware updates arrive over the CAN2.0 and RS485 links.
A six-thousand-cycle core: LiFePO4 cells keep 70% capacity beyond 6,000 cycles, warranted 10 years.

Frequently Asked Questions

Why does the GB-L Pro need so few modules?

Because each module contributes 102.4 V and 4 kWh, two to six of them already form a 204.8 to 614.4 V system holding 8 to 24 kWh.

What safety hardware does the GB-L Pro carry?

Explosion relief and fire protection are engineered into the pack, complemented by an IP65 enclosure and an anti-corrosion grade above C2.

Is the GB-L Pro suitable near the sea?

Its corrosion resistance is graded above C2 and the housing is IP65-sealed, which is exactly the specification coastal humidity calls for.

What does the GB-L Pro display and report?

A front LCD shows state of charge, power and total voltage, while CAN2.0 and RS485 carry data, and remote updates, to the inverter side.

What are the GB-L Pro weight and current figures?

Modules weigh 39 kg each and towers 97 to 253 kg; current is 40 A continuous with a 50 A peak sustained for 120 seconds, 20 A being recommended.
