PVBAT TIGER-T4-72 24kWh Mobile Battery Backup System
PVBAT TIGER-T4-72 is a high-capacity 24kWh mobile energy storage system designed for users who need dependable backup power, off-grid power, or mobile jobsite power. Unlike small handheld portable power stations, TIGER-T4-72 is a floor-standing battery backup system with built-in casters, larger battery capacity, 120/240V split-phase output, and stronger load tolerance for real-world power needs.
The system combines a 16.5kVA low-frequency transformer inverter with a 24kWh LiFePO4 battery pack to deliver stable pure sine wave AC power for homes, garages, farms, workshops, off-grid cabins, construction sites, warehouses, outdoor work areas, and mobile commercial operations. It is especially useful when grid power is unavailable, unstable, expensive, or difficult to access.
TIGER-T4-72 is designed to support many common backup loads, including refrigerators, freezers, lights, routers, water pumps, well pumps, compressors, power tools, communication equipment, and selected HVAC equipment. The low-frequency transformer inverter architecture helps the system handle motor-driven appliances and high inrush startup loads more effectively than many lightweight inverter designs.
With 24kWh rated battery energy, 76.8V rated voltage, 3:1 crest factor, 39kW instantaneous peak protection for 350ms, and a fast 10ms UPS/backup transfer function, TIGER-T4-72 is built for demanding backup and off-grid applications. Runtime will vary based on connected load size, startup surge, battery state of charge, solar input, ambient temperature, and operating conditions.
For plug-and-play use, compatible appliances can be connected directly to the built-in AC output ports. For connection to a home electrical panel, transfer switch, subpanel, or permanent electrical circuit, installation should be completed by a licensed electrician in accordance with local electrical codes and safety requirements.
- 24kWh LiFePO4 battery storage for long-duration backup, solar storage, off-grid living, farm power, and mobile work applications.
- 16.5kVA low-frequency transformer inverter designed for stable output and stronger tolerance with motor-driven loads and startup surge conditions.
- 120/240V split-phase pure sine wave AC output for North American homes, farms, workshops, cabins, and job sites.
- 3:1 crest factor with 39kW instantaneous peak protection for 350ms to help support demanding startup loads.
- 10ms UPS/backup transfer function for fast backup switching with compatible connected equipment.
- Solar and utility-grid charging support for backup power, solar storage, and off-grid applications.
- BE175 PV input connector with 90VDC-230VDC open-circuit voltage range for compatible solar configurations.
- Built-in NEMA interfaces, including SS2-50P AC input, 14-50R side output, L14-30R front output, and four 120V outlets.
- 8000-cycle design at 80% depth of discharge, with expansion capability up to 16 batteries in parallel.
- Wi-Fi / Bluetooth monitoring, 2x RS485 communication, touchscreen control, and built-in casters for practical daily use.
