Growing Need for Smart Solar Storage
Residential electricity demand is increasing due to:
- Electric vehicles
- Heat pumps
- Smart appliances
- Home automation systems
At the same time, solar generation is intermittent.
Solar panels produce maximum energy during daytime hours, while household consumption often peaks in the evening.
Without storage, excess solar energy is exported or wasted.
GRANKIA AIO-11K16LV solar energy storage system solves this challenge by storing surplus solar power and releasing it when electricity demand increases.
A Complete Energy Storage Architecture
The AIO-11K16LV is designed as an integrated single phase 11kW solar energy storage system.
It combines:
- Solar inverter
- LiFePO₄ battery module
- Battery management system (BMS)
- Energy monitoring platform
This integrated structure reduces installation complexity compared with traditional systems using separate inverter and battery cabinets.
Key Features and Benefits
1. Dual MPPT Solar Charging
Two independent MPPT trackers, each handling up to 27A, with a maximum PV array open-circuit voltage of 500VDC and an operating range of 60–450VDC.
The two strings can face different roof orientations or panel counts without one string dragging down the other’s output. Wide voltage range tolerates panel degradation and temperature swings.
| Feature | Traditional Single MPPT System | AIO-11K16LV Dual MPPT System |
| Solar Array Management | One tracking channel | Two independent tracking channels |
| Roof Orientation Support | Limited | Multiple orientations |
| Partial Shade Handling | Moderate | Improved |
| PV Expansion Capability | Lower | Up to 13kW PV input |
| Energy Harvesting Efficiency | Standard | Optimized |
Benefits:
Installers get flexible array design freedom, and owners of this solar energy storage system see more consistent daily harvest, even on partially shaded or multi-angle roofs.
2. High-Capacity LiFePO4 Battery Bank
The AIO-11K16LV solar battery system uses advanced LiFePO₄ battery technology, known for safety, durability, and long service life.
| Battery Parameter | Value |
| Battery Chemistry | LiFePO₄ |
| Nominal Voltage | 51.2VDC |
| Rated Capacity | 314Ah |
| Energy Capacity | 16.07kWh |
| Cycle Life | ≥8000 Cycles @ 80% DoD |
| Battery Configuration | 16S1P |
| Max. Discharge Power | 7200W |
Compared with traditional lead-acid batteries, LiFePO₄ technology offers:
- Longer lifespan
- Higher usable energy capacity
- Better thermal stability
- Lower maintenance requirements
- Faster charging performance
LiFePO4 chemistry is inherently more thermally stable than NMC alternatives, and the long cycle life stretches replacement intervals well beyond a decade of daily cycling.
This 16kWh lithium battery storage system reduces total cost of ownership per stored kWh, making it a durable core for any residential solar energy storage system deployment.
3. 11.2kW High-Power Single-Phase Output
The AIO-11K16LV provides an 11.2kW rated output power through a single-phase inverter platform.
Compared with standard 5kW-8kW residential storage systems, it supports higher household loads.
It can operate:
- Multiple air conditioners
- Kitchen appliances
- Water pumps
- Home office equipment
- EV charging equipment
Benefits
Users can achieve greater energy independence without upgrading to a complex three-phase system.
This makes it a suitable 11kW residential solar battery storage system for large homes requiring high power output.
4. Pure Sine Wave Inverter Output
Rated output current 48.7A, max output current 97.4A, surge power 22.4kW, pure sine wave waveform, frequency regulation at 50/60Hz ± 0.3Hz.
The surge rating (2× rated power) covers the inrush demand of motor-driven loads — pumps, compressors, air conditioners — without oversizing the whole system.
Benefits:
Sensitive electronics and heavy-start appliances run cleanly on the same single-phase solar energy storage system, avoiding nuisance trips during startup.
5. Multi-Layer Protection Architecture
PV-side reverse polarity, overvoltage and overcurrent protection; AC-side overcurrent, overvoltage, undervoltage and short-circuit protection; battery-side overcharge, over-discharge, undervoltage, overcurrent, over-temperature and short-circuit protection.
Protection is distributed across every power stage rather than centralized, so a single fault domain does not compromise the rest of the system.
This layered safety design supports long-term unattended operation, which matters for any solar energy storage system installed in a residential garage or utility room.
6. Smart Energy Control System
The integrated energy management system automatically controls:
- Solar charging
- Battery charging/discharging
- Load power distribution
- Grid interaction
The system can prioritize energy usage according to different strategies:
- Solar → Home Load
- Solar → Battery Charging
- Battery → Home Load
- Grid → Backup Support
Users can maximize renewable energy consumption and reduce electricity costs.
The system supports advanced applications such as:
- Peak shaving
- Load shifting
- Solar self-consumption optimization
Application Scenarios
Residential Solar Energy Storage
The system is suitable for:
- Large residential houses
- Villas
- Solar-powered communities
It stores daytime solar energy and supplies electricity during evening peak hours.
Backup Power Applications
During grid interruptions, the AIO-11K16LV provides continuous power support for essential loads.
Typical backup loads include:
- Refrigerators
- Lighting
- Internet equipment
- Security systems
- Medical devices
Off-Grid Solar Systems
For remote areas without reliable grid access, the system works as a complete energy solution.
It can integrate with:
- Solar panels
- Backup generators
- Smart monitoring platforms
Environmental and Mechanical Design
- Cooling: Intelligent forced-air cooling, matched to sustained high-load operation.
- Enclosure Rating: IP20, indoor floor-mounted installation only.
- Operating Temperature: Charge 0°C to 50°C; discharge -20°C to 50°C.
- Humidity Tolerance: 10–95% RH, non-condensing.
- Altitude: Rated below 1000m, with derating above that threshold.
These parameters are engineered in line with international standards commonly referenced for lithium-based energy storage safety and inverter grid interaction, such as IEC 62109 for inverter safety and IEC 62619 for lithium battery safety — benchmarks widely used to evaluate residential-scale solar energy storage systems.
