Battery Specifications

Physical Specifications

Inverter Compatibility

The SOK SK48V100N uses Bluetooth-based protocol selection in the SOK app to communicate with 30+ mainstream inverter brands, including:

• Victron MultiPlus-II, Quattro, EasySolar (RS485 + CANBus)
• EG4 (6000XP, 18000XP series)
• Sol-Ark (12K, 15K series)
• Schneider Electric (XW Pro, Conext)
• Outback Power (Radian, FX/FXR series)
• Magnum Energy (MS-PAE, MS-PE series)
• Growatt, Deye, Pylontech-protocol, Goodwe, and more

Switch protocols on-site via the SOK Bluetooth app — no firmware reflash required. Bluetooth OTA firmware updates ensure new inverter protocols can be added remotely as they're certified.

Smart Features

Bluetooth BMS: Pair with the SOK app (iOS + Android) for real-time monitoring of cell voltages, state of charge, current, temperature, and cycle count.

Bluetooth OTA firmware upgrades: The SOK app pushes firmware updates over Bluetooth — no cables, no SD cards. New inverter protocols and BMS improvements arrive remotely.

Smart cell balancing: Active top-balance balancing keeps all cells within tight voltage tolerance throughout the charge cycle, extending overall pack lifespan and capacity.

Self-Heating Specs

The built-in heater pad activates automatically when the cell temperature drops below the safe charging threshold (32°F / 0°C). Power for the heater is drawn from the charger or solar input — not from the battery cells — so cold-weather charging does not drain stored capacity. The battery can safely accept charge at ambient temperatures down to -4°F (-20°C).

The 100W heater pad on this server-rack battery rapidly warms the cell pack from cold storage temperatures.

Parallel & Series Configurations

Connect up to 16 SK48V100N units in parallel for larger capacity (1600Ah max parallel bank @ 48V). Series connections support up to 1 units in series for higher-voltage banks (48V max series). For mixed parallel+series banks, follow the SOK installation manual — all batteries must be at the same state-of-charge before initial series connection.
