Suitable Applications

The RUiXU Lithi2-16 is designed for compatible residential and commercial energy storage systems, including solar battery storage, backup power, off-grid installations, and larger battery-bank configurations. Its 16kWh capacity, self-heating function, integrated display, and parallel expansion capability make it suitable for energy-storage projects that require substantial capacity in a movable floor-standing enclosure.

Self-Heating & Cold-Weather Operation

The integrated 480W heater operates from a 56V supply and uses charging power to warm the battery in low-temperature conditions. Self-heating starts when the battery temperature is at or below 41°F (5°C) and stops when the battery reaches approximately 53.6°F (12°C). The specified charging operating temperature extends down to -25°C (-13°F).

LCD Touch Screen

The Lithi2-16 includes a 5-inch capacitive LCD touch screen that displays battery information and allows adjustment of available battery settings. The integrated display provides direct access to battery information without requiring a separate external monitoring device.

Inverter Communication

The battery includes RS485 and CAN communication interfaces for compatible inverter and energy-management equipment. The supplied product information lists CAN communication compatibility with systems from Victron, SMA, Studer Innotec, Sofar, Sol-Ark, Solis, GoodWe, Deye, Growatt, SAJ, LuxPower, Megarevo, INVT, Sermatec, TBB, MUST, Sunsynk, and Schneider. RS485 compatibility is listed for MPP, Voltronic, RCT, and Alpha Outback systems.

Parallel Expansion

Up to 32 compatible batteries can be connected in parallel for larger energy-storage installations. Parallel expansion should use appropriately sized battery cables, communication connections, overcurrent protection, and compatible inverter equipment according to the manufacturer's installation requirements.

Safety & Protection

The battery includes a Battery Management System, intelligent cell-balancing functions, a negative-terminal fuse, and a positive-terminal micro circuit breaker. Quick-plug connections provide up to 250A continuous overcurrent capacity. A gas aerosol fire-protection module is also included for additional internal protection, while a side inspection port provides access to the BMS and fuse for maintenance.

Installation & Mobility

The Lithi2-16 includes four concealed heavy-duty wheels for movement within the installation area and a rear anti-tipping mounting point for wall fixation. The electro-coated enclosure provides corrosion protection, while the IP55 rating supports protected indoor and outdoor installations. When installed outdoors, provide appropriate shelter and protection from direct weather exposure.

Important Usage Note

Actual battery performance, usable capacity, charging time, cycle life, and output depend on inverter configuration, depth of discharge, charge and discharge rates, temperature, wiring, and installation conditions. Do not exceed the specified battery voltage, charge current, discharge current, or operating-temperature limits. Verify inverter communication, system protection, cable sizing, grounding, mounting, and local installation requirements before commissioning.
