UZ 16 kWh Battery (IG-16K-U)

Product Overview

The UZ Energy IG-16K-U is a 16 kWh low-voltage LFP (LiFePO4) home battery for solar energy storage and backup. It provides 16.0 kWh rated / usable energy at 51.2 V nominal (314 Ah) with an IP65 enclosure for outdoor or garage installations within its temperature limits.

Maximum charge power is 8.2 kW and maximum continuous discharge power is 10.24 kW, with a 12.8 kW / 250 A peak discharge for 15 seconds. An integrated BMS and layered safety features manage cell, electrical, and thermal conditions; optional heating supports charging down to −20°C.

Best For

• 48 V / 51.2 V residential storage needing a full 16 kWh in one wall-mount / floor cabinet
• Outdoor-rated (IP65) installs in cold climates when the heating option is configured
• Systems that may expand by paralleling additional IG-16K-U units (manufacturer max 64; recommended ≤ 16 parallels)

Compatibility / Important Considerations

• Confirm CAN/RS485 closed-loop support with your specific hybrid or off-grid inverter before purchase — do not assume all 48 V inverters are validated with IG-16K-U.
• Plan for cabinet weight (~276 lb) and IP65 mounting clearances.
• Parallel expansion must follow UZ wiring, addressing, and inverter limits.
• Professional installation required.
