The system can:
- Learn electricity price patterns
- Analyze user consumption behavior
- Integrate renewable energy forecasts
- Automatically optimize charge/discharge cycles
With up to 8 customizable time segments, this smart EMS significantly increases efficiency and ROI for end users—making it highly attractive for solar installers targeting premium residential projects.
Scalable Solar Battery Storage up to 64 kWh
The HiOne system is built around a modular solar battery architecture, allowing flexible scaling:
- Battery capacity per unit: 8 kWh
- Maximum storage: 64 kWh (8 batteries)
- Cycle life: 8000 cycles (LiFePO₄)
- Built-in SOC balancing for mixed battery use
This scalability makes it ideal for:
- High-consumption households
- EV charging + solar setups
- Smart home energy systems
- Backup power solutions
For solar wholesalers and distributors, this modularity simplifies stock management and upselling opportunities.
High-Performance Solar Inverter with Multi-MPPT Design
The HiOne inverter range is optimized for modern solar panel installations, offering:
- AC output range: 8 kW – 20 kW
- Maximum PV input: up to 40 kW
