The SRNE 12kW 48V 3-Phase On/Off-Grid Hybrid Solar Inverter (Model HESP48120SH3) is a powerful and intelligent energy management solution designed for larger residential, commercial, and light industrial applications in Nairobi, Nairobi County, Kenya, and beyond. This three-phase inverter seamlessly integrates solar energy harvesting, substantial 48V battery storage, and smart grid interaction. Featuring a robust 100A battery charger, a wide 500VDC maximum PV input voltage, and a rugged IP65-rated enclosure, it offers exceptional performance, flexibility, and durability for demanding power requirements. This inverter maximizes self-consumption of solar energy, provides balanced and reliable 3-phase backup power during grid outages (common in Nairobi’s commercial and industrial areas), and contributes to significant reductions in electricity costs.
Key Features:
- High Power Output (12kW): Capable of handling significant energy demands for larger homes, businesses, and light industrial facilities requiring three-phase power, prevalent in Nairobi’s commercial zones.
- 3-Phase Output (Typically 380/400V): Provides balanced and stable three-phase AC power suitable for a wide range of commercial and industrial equipment commonly used in Nairobi.
- 48V Battery System Compatibility: Designed for efficient integration with substantial 48V battery banks (compatible with lead-acid and lithium-ion options), offering extended backup power for critical three-phase loads during prolonged outages experienced in Nairobi.
- Powerful 100A Battery Charger: Enables rapid and efficient charging of the 48V battery bank from solar, grid, or a generator, ensuring quicker recharge times and greater energy availability for three-phase applications.
- Wide 500VDC Maximum PV Input Voltage: Offers significant flexibility in solar array design, allowing for longer string lengths and compatibility with various solar panel configurations, optimizing energy harvest under the Kenyan sun for larger installations.
- On/Off-Grid Hybrid Operation: Supports both grid-tied operation (selling excess solar power back to the grid if regulations allow in Nairobi for 3-phase systems) and off-grid functionality with seamless switching for uninterrupted three-phase power supply.
- Multiple Intelligent Working Modes:
- Self-Consumption Mode: Prioritizes solar energy for powering three-phase loads and charging batteries, minimizing reliance on the grid for commercial operations.
- Force Time Use Mode: Allows scheduling of battery charging and discharging based on electricity tariffs or specific operational needs for businesses in Nairobi.
- Battery Priority Mode: Primarily utilizes battery power for three-phase loads, with solar charging the batteries and the grid as a backup.
- Grid Tie Mode: Feeds excess solar power back to the grid (if applicable for 3-phase in Nairobi).
- Off-Grid Mode: Operates independently from the grid, relying solely on solar and battery power for three-phase loads in areas with unreliable grid access.
- High Efficiency: Optimized design and components ensure high energy conversion efficiency, maximizing the utilization of solar power and minimizing energy losses in larger three-phase systems.
- Robust IP65 Protection Rating: Features a weatherproof enclosure suitable for outdoor installation, offering excellent protection against dust and water ingress, crucial for the diverse environmental conditions in Kenya, especially for commercial and industrial installations.
- Remote Monitoring and Control: Typically includes Wi-Fi or other communication interfaces for convenient monitoring of system performance and parameter adjustments via a mobile app or web portal, allowing businesses in Nairobi to manage their energy system remotely.
- Comprehensive Protection Features: Includes protection against PV over-voltage, PV reverse polarity, AC over-current, AC over-voltage, short circuit, over-temperature, and battery over/under voltage, ensuring system safety and longevity for valuable three-phase equipment.
- Parallel Operation Capability (Check Specific Model): Some models may support parallel operation, allowing for system expansion to meet future power needs of larger commercial or industrial properties in Nairobi.
- Generator Compatibility: Can be seamlessly integrated with a generator for additional backup power for critical three-phase loads during extended periods of low solar production or deep battery discharge.
Typical Applications;
- Larger Residential Homes with 3-Phase Power: Provides energy independence, significantly reduces electricity bills, and offers reliable three-phase backup power for homes with substantial power requirements.
- Commercial Buildings (Small to Medium Scale): Powers offices, workshops, small factories, restaurants, and other commercial establishments in Nairobi with three-phase equipment, reducing operating costs and ensuring business continuity during power interruptions.
- Agricultural Operations: Can power larger three-phase water pumps, processing machinery, and cold storage in agricultural settings around Nairobi, improving energy reliability and reducing operational costs.
- Educational Institutions and Healthcare Facilities: Offers a reliable and cost-effective three-phase power solution with backup capabilities for schools, clinics, and small hospitals with three-phase equipment.
- Telecommunication Towers and Base Stations: Provides a stable and independent three-phase power source for communication infrastructure.
- Small Industrial Workshops and Facilities: Powers three-phase machinery, tools, and lighting in industrial settings around Nairobi, ensuring operational continuity.
- Microgrid Applications: Forms the core of small-scale independent three-phase power grids for communities or businesses in areas with unreliable grid access in Kenya.
