Description
Each module is 51.2 V and 100 Ah. Modules in the rack are wired in series, so every added module raises the voltage while the working current stays the same. At equal power the higher voltage cuts the current in the DC line, and the cable to the inverter ends up thinner than with a 48 V battery. Cycle life is at least 6,000 cycles, and the IP20 enclosure is meant for indoor installation. The batteries carry UN 38.3, CE, IEC 62040, CEC and VDE certification. For North America there is the BOS-GL/GH version with UL 1973, UL 9540A and UL 9540.
How to choose
Pick the module count so the rack voltage lands inside the inverter's input window and the energy covers the daily discharge. 3 modules give 153.6 V and about 15 kWh, 12 modules give 614.4 V and about 60 kWh, and the G Pro comes in when that is not enough and up to 81.92 kWh is needed. Projects that call for UL listings take the BOS-GL/GH. If you need more energy and a ready outdoor cabinet with a PCS suits better, the MS-G215 at 100 kW and 215 kWh is closer.

FAQ
How many modules are in a BOS-G battery?
From 3 to 12 modules of 5.12 kWh, at 153.6–614.4 V.
What is the maximum capacity of the BOS-G Pro?
Up to 81.92 kWh.
Does the BOS-G have UL certification?
Yes, the BOS-GL/GH version for North America holds UL 1973, UL 9540A and UL 9540.
Can the BOS-G connect to a 48 V inverter?
No, the rack runs at 153.6–614.4 V and needs a high-voltage hybrid inverter. A 48 V system calls for 51.2 V modules such as the NEPT S series.
What current can the BOS-G handle?
100 A in normal duty and a 125 A peak for 2 min.
