GB-L Pro / GB-SL Pro — 8–24 kWh high-voltage battery and all-in-one system
Country: China · Model: GB-L Pro / GB-SL Pro
The GB-L Pro stacks 4 kWh, 102.4 V LiFePO4 modules into a high-voltage home battery. Models from the GB-L8 to the GB-L24 PRO give 7.2–21.6 kWh of usable energy. The GB-SL Pro version puts a three-phase 5–20 kW hybrid inverter into the same stack with an 8–24 kWh battery.

Description
The figure in the model name matches the battery's nominal energy in kWh, so the GB-L8 has two modules and the GB-L24 PRO has six. Modules are connected in series and the voltage climbs in steps of 102.4 V, so the battery connects only to a high-voltage hybrid inverter. Recommended current is 20 A with a 50 A peak, and at this voltage the DC cable between battery and inverter stays thin. The LCD shows state of charge (SOC), power and voltage, so status checks need no laptop. In the GB-SL Pro the inverter and battery share one stack, the battery inside is built within 8–24 kWh, and installation comes down to wiring the grid, the panels and the loads.
How to choose
If a high-voltage hybrid inverter is already on site, take the GB-L Pro, and if not, the GB-SL Pro with its three-phase 5–20 kW inverter covers the whole set in one stack. Capacity goes up in 4 kWh steps, from the GB-L8 for overnight lighting and a fridge to the GB-L24 PRO for a house with pumps and a boiler. A home with a 48 V inverter needs low-voltage NEPT S modules at 51.2 V instead, and a larger inverter-plus-battery kit comes as the AI-W16 with 16–96 kWh.

FAQ
What usable energy does the GB-L Pro offer?
7.2–21.6 kWh, from the GB-L8 to the GB-L24 PRO.
Which inverter is built into the GB-SL Pro?
A three-phase 5–20 kW hybrid inverter with an 8–24 kWh battery.
What is the voltage of a GB-L Pro module?
102.4 V with 4 kWh per module.
Will the GB-L Pro work with a 48 V inverter?
No, the 102.4 V modules connect in series, so the battery needs a high-voltage hybrid inverter.
What does the GB-L Pro display show?
State of charge (SOC), power and battery voltage. Working current is 20 A, with a 50 A peak.
