Core Advantages Summary (Refined from Technical Data):
Focusing on energy efficiency, compatibility, power supply reliability, safety, environmental adaptability, operation convenience, and compliance/warranty, this inverter series delivers end - to - end value for residential/commercial PV + storage scenarios:
Leading Efficiency, Cost & Energy Savings
Max PV - to - AC efficiency 97.3% (European efficiency 96.8%) and BAT - to - AC efficiency 94.3% outperform industry averages, minimizing energy loss in power generation and storage to directly cut electricity costs.
“All - Scenario” PV Input Compatibility
With max PV input power 10,000W, voltage range 90V - 550V (start - up voltage 90V), and dual MPPT (voltage range 70V - 540V, 2 strings per MPPT), it adapts to PV arrays of different powers/layouts (e.g., multi - row modules, complex roofs), ensuring high generation efficiency even under shading or low - light.
“Full - Compatibility & High - Throughput” Energy Storage
Supports lithium - ion/lead - acid batteries (nominal 48V, voltage range 40V - 65V) with charging/discharging current 75A - 135A and power 4,000W - 6,600W. Compatible with mainstream battery types/capacities, the high - current/power design enables “fast charging & sufficient discharging” for high - load demands of homes/small businesses.
Dual Reliability: Grid - connected & Backup
Grid - connected: Power range 3kW - 6kW for diverse scenarios, with power factor >0.99 and THDI <3%, meeting high - standard grid power quality;
Backup: Output power matches nominal rating, with peak 10,000VA and transfer time <10ms (typical). It “seamlessly takes over” loads during grid outages, ensuring zero flicker for sensitive devices like computers and refrigerators.
9 - Layer Safety, International Standard
Class I protection + DC switch, anti - islanding, AC/DC over - current/voltage, short - circuit, surge (DC Type III/AC Type III), insulation detection, and leakage current protection. A full - link safety barrier from PV modules to grid, complying with IEC and other international safety standards.
No Compromise in Extreme Environments
IP65 protection (dust - and - water - proof), max operating altitude 4,000m (derating above 2,000m), operating temperature -25℃ to 60℃ (derating above 45℃), and 0 - 100% humidity adapt to humid/coastal areas. Dual - mode cooling (natural + smart fan) ensures stable operation in plateaus, deserts, and rainy seasons.
Lightweight Installation & Smart Operation
Wall - mounted, with dimensions 367mm×421mm×215mm and weight 16kg, enabling easy installation on small residential or commercial roofs;
LED/LCD dual display + RS485/CAN/DRMS communication (Wi - Fi/LAN optional) supports local + remote monitoring with one click. Flexible cluster networking improves operation efficiency by over 50%.
Global Compliance & Long - term Warranty
Certified by 10 + international standards (e.g., IEC 61727/62116, covering EU, US, Australia, New Zealand), with optional 5 - year/10 - year warranty. “Compliance for global markets + long - term peace of mind” dual guarantee.
