Core Advantages Summary:
Reasons Why Customers Purchase This Inverter
Based on the technical data sheet, customers choose this inverter due to its high efficiency, system compatibility, reliable backup power, robust safety, environmental resilience, smart management, and regulatory compliance, detailed as follows:
-
Energy Efficiency for Cost Savings The inverter delivers top - tier conversion efficiencies: up to 97.8% (PV to AC), 97.5% (European efficiency for PV to AC), and 97.0% (battery to AC). These high efficiencies minimize energy loss during solar power conversion and battery discharge, directly reducing long - term electricity costs.
-
PV System Compatibility
- Power & Voltage Range: It can support a 12,000W maximum PV input power and a 550V maximum PV voltage, making it suitable for small to medium - sized solar arrays.
- MPPT Flexibility: With an MPPT operating voltage range of 70V–540V, 16A/16A maximum input current per MPPT, and 2 MPPT channels, it can efficiently track power from various PV modules (even in low - light conditions) and can accommodate mixed panel configurations.
-
Energy Storage Versatility
- Battery Compatibility: It supports both lithium - ion and lead - acid batteries, allowing users to either repurpose existing lead - acid setups or adopt modern lithium - ion systems.
- Charge/Discharge Performance: A battery voltage range of 80V–480V, 42A maximum charge/discharge current, and up to 9kW charge/discharge power ensure seamless integration with home or small commercial energy storage systems.
-
Reliable Grid - Tied & Backup Power
- Grid - Tied Output: It can deliver 3kW–6kW nominal AC output power (for example, 3,000W for SP3KH and 6,000W for SP6KH) with >0.99 power factor and <3% THDi, ensuring grid - compliant and clean electricity.
- Backup Power: It provides 3kW–6kW nominal backup output power with a transfer time <10ms (typical), ensuring “zero - perception” switching to battery power during outages. This is crucial for sensitive loads such as medical devices or home offices.
-
Comprehensive Safety Protections
- Electrical & Structural Safeguards: It has Class I protection (anti - electric shock), DC switch, anti - islanding protection, overcurrent/overvoltage protection (DC Type II, AC Type III), short - circuit/reverse polarity protection, and surge arresters (DC Type III, AC Type III). These features eliminate the risks of electric shock, fire, or system failure.
- Leakage & Insulation Safety: It includes insulation resistance detection and optional leakage current protection (AFCI) for added safety in residential and commercial settings.
-
Harsh Environment Resilience
- Altitude & Climate Tolerance: It can operate at up to 4,000m altitude (with derating above 2,000m), - 25°C to 60°C (with derating above 45°C), and 0–100% relative humidity. The IP66 ingress protection and natural cooling ensure its reliability in dusty, wet, or extreme - temperature environments (such as highlands, deserts, and tropical regions).
-
Smart Monitoring & Easy Installation
- User - Centric Control: It offers Bluetooth, APP, LED status indicators, and optional LCD display for real - time system monitoring.
- Communication & Integration: It supports RS485, CAN (for BMS), DRM/RS485 (for meters), and optional Wi - Fi/LAN, enabling seamless integration with home energy management systems.
- Installation: Wall bracket mounting and MC4/H4 PV connectors simplify the deployment process for installers.
-
Regulatory Compliance & Warranty
- Global Certifications: It meets standards like IEC 62109 - 1/2, EN 50549 - 1, VDE 4105, A4777, CEI 0 - 21, G98/G99/G100, RD 1699/661/647/413, UNE 217002, ensuring compliance in European, Australian, and other markets.
- Warranty: It comes with a 5 - year standard warranty and 10 - year optional extension, reducing long - term maintenance risks.
Core Advantages of the Inverter
The inverter’s competitive strengths lie in efficiency, adaptability, reliability, safety, environmental toughness, and smart connectivity, as highlighted by technical specifications:
-
Industry - Leading Efficiency
- It achieves 97.8% maximum PV - to - AC efficiency and 97.0% battery - to - AC efficiency, which is better than the average market levels. Low energy loss translates to higher solar yield and longer battery runtime.
