Product Description:
The ACETECH BOX 2 series is a low-voltage residential energy storage solution engineered for seamless home integration. Supporting up to 15 parallel units, it delivers scalable capacity from 10.24kWh to 153.6kWh. Its breakthrough 6.5-inch slim profile eliminates space constraints, while 1C discharge capability (5.12kW/10.24kW max) ensures uninterrupted power for high-demand appliances. Built with UL-listed LiFePO₄ cells and smart safety systems, it offers industry-leading longevity with 6,000+ cycles at 80% DoD.
Key Parameters:
| Specification | ACE BOX 2 | ACE BOX 2 Pro |
|---|---|---|
| Nominal Energy | 5.12 kWh | 10.24 kWh |
| Nominal Voltage | 51.2 V | 51.2 V |
| Capacity | 100 Ah | 200 Ah |
| Max Discharge Current | 100 A (150A Pro*) | 150 A (200A*) |
| Dimensions (W×H×D mm) | 660×550×140 | 680×490×225 |
| Weight | 52.3 kg | 87.2 kg |
| Cycle Life | ≥6,000 cycles (80% DoD, 25°C) | |
| Warranty | 5 years (terms apply) | |
| *Note: Conflicting max current data in docs (100A/150A vs 200A); conservative values listed. |
Performance Curves Highlights:
Discharge: Maintains stable voltage at 0.5C across 20°C–40°C; capacity drops at -20°C.
Cycle Life: Retains >80% capacity after 6,000 cycles (80% DoD, 25°C). High temperatures reduce longevity.
Self-Discharge: Loses <10% capacity after 12 months at 25°C storage.
Key FAQs:
Q1: How many units can be connected in parallel?
A: Up to 15 units for combined 153.6kWh capacity (documentation notes 10 units in specs; confirm with manufacturer).
Q2: What inverters are compatible?
A: Supports Deye, Growatt, Solis, VOLTPOWER, LUVPOWER via RS485/RS232/CAN communication.
Q3: What is the operating temperature range?
A: Charging: 0°C to 65°C; Discharging: -20°C to 65°C.
Q4: How does temperature affect performance?
A: Capacity reduces below 0°C; high temperatures accelerate cycle life degradation (see curves).
Q5: What safety features are included?
A: Auto pressure relief, 5-second fire suppression response, and low-voltage disconnect.
