System Energy Flow
The HV-AIO operates in three core modes: Charging (PV → All-in-One → Battery), Discharging (PV / Battery → All-in-One → Loads / Grid), and Backup (Battery → All-in-One → Critical Loads, grid-isolated). The EMS automatically selects the optimal mode based on tariff signals, PV generation, load demand, and battery state of charge.
Frequently Asked Questions
Q1: What is the maximum PV input power for this unit?
The HV-AIO 100kW series supports four independent MPPT inputs with a maximum total PV input of 153.6kW (4 × 38.4kW), max PV voltage of 850Vdc, and max PV current of 256A total (4 × 64A).
Q2: How fast is the switch to backup power during a grid outage?
The system switches from grid-tied to off-grid (island) mode in less than 10 milliseconds, ensuring continuous operation for critical loads without interruption.
Q3: What cooling method does this system use?
The standard configuration uses liquid cooling for precise battery temperature control. Air cooling is available as an optional alternative for milder climates.
Q4: Can multiple units be paralleled?
Yes. The system supports multi-machine parallel connection for scalable capacity. Battery modules can also be flexibly added or removed to match project requirements.
Q5: What certifications does the battery carry?
The LiFePO4 battery cells are certified to UN38.3 and MSDS safety standards. The integrated BMS provides comprehensive over-voltage, over-current, short-circuit, and over-temperature protection.
Q6: Does IMAXPWR provide customized solutions?
Yes. As an original equipment manufacturer, IMAXPWR offers deeply customized all-in-one energy storage solutions including system configuration, communication protocols, and enclosure designs to meet specific project requirements.
