RUiXU Lithi2-16 16 kWh Battery (LITHI2-16)

Product Overview

The RUiXU Lithi2-16 (LITHI2-16) is a 16 kWh low-voltage lithium iron phosphate (LFP / LiFePO4) battery for residential and light commercial solar energy storage. It operates at 51.2 V nominal (314 Ah) with 16 kWh usable capacity at 100% depth of discharge (DoD).

Use it when you need a large single-cabinet 48 V-class battery with closed-loop CAN / RS485 communication to a compatible inverter/charger. On-board self-heating supports charging in cold conditions, and the cabinet includes wheels plus a wall anti-tip mount.

Best For

• 48 V / 51.2 V solar-plus-storage and backup systems needing ~16 kWh per cabinet
• Installs that want self-heating for cold-climate charging
• Scalable banks (manufacturer states expansion from 16 kWh toward multi-cabinet totals — follow RUiXU parallel limits for your inverter)

Key Features

Compatibility / Important Considerations

• Confirm closed-loop CAN/RS485 profile with your specific inverter (including any RUiXU SUNON pairing) before assuming compatibility — same-brand equipment is not automatically validated for every firmware.
• Follow manufacturer parallel / expansion limits and DC connector current ratings.
• Heavy cabinet (~302 lb): plan material handling, flooring, and anti-tip wall anchoring.
• Professional installation required for battery DC interconnection and protection.
