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
- Keeps working at 60 degrees C: Discharge is rated from -20 up to 60 degrees C, five degrees past the common ceiling.
- 4.09 kWh GB-LM4.0 modules: Two to six modules of 102.4 V each combine into 8.18 to 24.54 kWh of storage.
- Type II surge shields: Overvoltage protection of DC Type II and AC Type II covers both sides of the connection.
- Ten towers side by side: Up to 10 stacks parallel for larger homes, over CAN2.0 and RS485.
- Silent natural cooling: No fans at all: natural cooling carries the heat while cycle life passes 6,000 cycles.
- Charge that adapts itself: The lithium charging strategy adapts itself to the BMS without manual profiles.
Frequently Asked Questions
How does the GB-SL handle very hot climates?
Its discharge window extends to 60 degrees C, higher than the 55-degree limit common elsewhere, and natural cooling avoids fan wear in dusty heat.
What storage sizes does the GB-SL offer?
From 8.18 kWh with two GB-LM4.0 modules to 24.54 kWh with six, of which 7.36 to 22.08 kWh is usable at 90% depth of discharge; ten towers can then be paralleled.
Does the GB-SL protect against grid surges?
Yes, it integrates Type II overvoltage protection on the DC side and Type II on the AC side.
How does charging work on the GB-SL?
The lithium charging strategy self-adapts to the BMS; current is 40 A continuous, 20 A recommended, with a 50 A discharge peak lasting 120 seconds.
What are the physical facts of a GB-SL tower?
It measures 540 x 1980 x 385 mm, weighs 137 to 293 kg depending on module count, seals to IP65 and stands on the floor below 2,000 m altitude.
