Summary of Core Advantages:
1. Leading Energy Efficiency, Maximizing Energy Utilization
Max. Efficiency (PV to AC) reaches 97.3%, European Efficiency (PV to AC) is 96.8%, and Max. Efficiency (BAT to AC) is 94.3%. Value: Reduce energy loss during conversion, improve energy utilization of PV and energy storage systems, and save electricity costs in the long run.
2. Flexible PV Input, Efficient Power Generation in All Scenarios
Wide Power & Voltage Range: Max. PV Input Power covers 3,000W - 10,000W (multiple models adapt to different installation scales), Max. PV Voltage is 550V (compatible with high - voltage PV modules), and Start - up Voltage is as low as 90V (quick start in low - light conditions).
Intelligent MPPT Tracking: MPPT Voltage Range is 70V - 540V (wide - range capture of solar power), with dual MPPT design and 1 string per MPPT (suitable for complex shading and multi - module parallel scenarios). Value: Efficiently track solar energy in “strong/weak light”, “small - scale home/large - scale commercial”, or “partial shading” environments to increase total power generation.
3. Strong Energy Storage Compatibility, Efficient Charging & Discharging Response
Battery Type Compatibility: Supports both Lithium - ion and Lead - acid batteries, compatible with mainstream energy storage solutions.
Flexible Voltage & Power: Nominal Battery Voltage is 48V, Battery Voltage Range is 40V - 65V (compatible with different capacity/brand batteries); Max. Charging/Discharging Current covers 75A - 135A, and Max. Charging/Discharging Power covers 4,000W - 6,600W (e.g., SP6KL reaches 135A/135A, 6,600W/6,600W, quickly responding to time - of - use electricity prices, power outage emergencies, etc.). Value: Compatible with existing energy storage systems and efficiently meet scenarios like “peak shaving & valley filling” and “emergency power supply”, improving the practicality of energy storage systems.
4. Stable AC/DC Output, Excellent Power Quality & Compatibility
Grid - tied Output: Nominal AC Output Power ranges from 3,000W to 6,000W, Max. AC Apparent Power ranges from 3,300VA to 6,600VA; Output Voltage is compatible with 220V/230V/240V (suitable for grids in different countries/regions), Frequency is adjustable between 50Hz/60Hz, Power Factor > 0.99 (@rated power), and THDI < 3% (excellent power quality to protect precision equipment).
Back - up Output: Nominal Output Power ranges from 3,000W to 6,000W, Peak Output Power (10s) reaches 6,000VA - 10,000VA (e.g., SP6KL is 10,000VA, stably powering impact loads like air conditioners and motors); Typical Transfer Time is 10ms (seamless switch for loads during power outage, ensuring power supply continuity). Value: In home, shop, small industrial and commercial scenarios, it can stably operate in grid - tied/off - grid modes, be compatible with different grid standards, and protect sensitive loads such as computers and medical equipment.
5. Multiple Safety Protections, Stable Operation in Extreme Environments
Comprehensive Electrical Protection: Protection Category Class I (mandatory grounding), with anti - islanding protection, AC/DC over - current/over - voltage protection, short - circuit protection, surge protection (DC Type III, AC Type III, Type II optional), insulation detection, leakage current protection, etc.
Excellent Environmental Tolerance: Protection Degree IP65 (dust - proof and water - proof, supporting outdoor installation); Operating Temperature Range is - 25℃ - 60℃ (derating above 45℃), Relative Humidity is 0 - 100% (stable operation in severe cold, high temperature, and humid environments); Max. Operation Altitude is 4,000m (derating above 2,000m, suitable for high - altitude areas). Value: In special regions like coastal areas, plateaus, and northern frigid regions, the equipment has dual guarantees of durability and safety, reducing maintenance costs.
Installation - friendly: Adopts wall bracket installation (space - saving), weight is only 16Kg (easy to carry and install); Cooling solutions adapt to scenarios (natural cooling or smart fan cooling, e.g., SP6KL uses smart fan, low noise and automatic adjustment).
Intelligent Interaction & Networking: Equipped with LED + LCD dual displays (local status visualization); Communication interfaces support RS485/CAN (battery management, parallel expansion), DI/DO (hardware control), and optional Wi - Fi/LAN (remote monitoring, real - time mastery of system status). Value: Lower installation threshold, easy for ordinary users to get started; remote/local monitoring makes maintenance more efficient and reduces manual inspection costs.
7. International Certification + Flexible Warranty, Worry - free Long - term Use
Compliance Guarantee: Certified by IEC 61272/62116/61689 (grid - tied), IEC/EN 62109 - 1&2 (safety), IEC/EN 61000/62920 (EMC), and other international authoritative certifications, with global recognition of quality and safety.
After - sales Commitment: Provides a 5 - year standard warranty with an optional 10 - year extended warranty, far exceeding the industry average. Value: Low procurement risk and guaranteed long - term use, allowing enterprise and home users to invest with confidence.
