SE-G5.1 / SE-G10.2 / SE-G5.1 Pro B — 48 V 5.12 / 10.24 kWh rack batteries
Country: China · Model: SE-G5.1 / SE-G10.2 / SE-G5.1 Pro B
SE-G rack-mount LiFePO4 modules run at 51.2 V and come in two capacities, 5.12 kWh (100 Ah) and 10.24 kWh (200 Ah). They fit a 19-inch rack, hang on a wall or stand on the floor, and serve home and small commercial systems built around a 48 V hybrid inverter. Up to 64 modules connect in parallel for 327 kWh.

Description
The SE-G5.1 and SE-G10.2 differ in capacity, and the range carries 50–100 A continuous current. To the inverter this is a 48 V class battery, so cable cross-section and breaker rating are sized by current rather than by voltage. Cycle life is at least 6,000 cycles and the enclosure is IP20, which calls for a dry, dust-free indoor spot. Without a cabinet the module hangs on a wall or stands on the floor. The SE-G5.1 Pro B adds a built-in 125 A breaker and an optional heater.
How to choose
The deciding figure is how much energy the site needs overnight or during a grid outage. The 5.12 kWh module suits small loads and lets you add capacity in fine steps, while the SE-G10.2 at 10.24 kWh halves the number of modules and jumpers in the rack. When the inverter and battery should come as one kit, the AI-W16 with 16 kWh modules and 16–96 kWh of capacity is the closer match.

FAQ
How many SE-G modules can run in parallel?
Up to 64 modules, 327 kWh in total.
What current do the SE-G5.1 and SE-G10.2 batteries deliver?
50–100 A continuous, depending on the model, and the rack busbar must carry the combined current. Cable and breaker on the inverter line are chosen from this value.
What does the SE-G5.1 Pro B add?
A built-in 125 A breaker that simplifies the DC panel, plus an optional heater. The heater matters when the battery sits in an unheated room.
Can an SE-G battery go in a garage or outdoors?
The IP20 enclosure is meant only for a dry room free of dust and moisture. For outdoor sites the same maker offers the SE-F12 Max and SE-F16 Max rated IP65 with up to 11.8 kW output.
Does the SE-G work with a 48 V inverter?
Yes, the 51.2 V nominal places it in the 48 V battery class. Each module is rated for at least 6,000 cycles.
