The PVBAT 16.5kVA + 24kWh Home Energy Storage System provides reliable solar backup power for homes, farms, off-grid properties energy storage.
Why Choose a Low-Frequency Inverter?
TIGER-T4-72 uses a low-frequency transformer inverter designed to better handle motor-starting and high-inrush loads. It is suitable for applications such as well pumps, water pumps, refrigerators, compressors and workshop tools, subject to the equipment’s rated power and startup surge requirements.
- 16.5 kVA inverter capacity
- 13 kW continuous active power output
- 24 kWh LiFePO4 battery capacity
- 120/240V split-phase output
Actual compatibility and runtime depend on the connected load, startup surge, battery state of charge and installation conditions.

Plan Backup Around Your Actual Load
Use these examples to estimate how much time a 24kWh system could provide. They assume 80% depth of discharge and 90% conversion efficiency: 24 × 0.80 × 0.90 = 17.28kWh for this calculation.
| Combined running load | Estimated runtime |
|---|---|
| 500W | 34.6 hours |
| 1,000W | 17.3 hours |
| 1,500W | 11.5 hours |
| 2,000W | 8.6 hours |
Calculation examples, not guaranteed runtime or a load-starting test. Actual results depend on equipment cycling, startup surge, battery state, temperature, standby losses and installation. Solar charging is not included in these estimates.

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, a 16.5kVA inverter and 13kW continuous active output, TIGER-T4-72 supports compatible 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.
- 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.
- Wi-Fi / Bluetooth monitoring, 2x RS485 communication, touchscreen control, and built-in casters for practical daily use.
