Summary of Core Advantages for SP Series Inverters:
1. Benchmark Energy Efficiency: Minimize Energy Conversion Loss
- PV to AC Conversion: Max. Efficiency reaches 97.3%, European Efficiency is 96.8%; BAT to AC Conversion efficiency is 94.3%. Value: Industry - leading energy conversion efficiency significantly reduces energy loss in PV and energy storage systems, saving electricity costs and enhancing energy utilization value during long - term operation.
2. Flexible PV Input: Efficient Power Generation in All Scenarios
- Power & Voltage Coverage: Max. PV Input Power is up to 10,000W (suitable for large - scale PV arrays), Max. PV Voltage is 550V (compatible with high - voltage modules), and Start - up Voltage is as low as 90V (quick start in low - light or dawn/dusk periods).
- Intelligent MPPT Tracking: MPPT Voltage Range is 70V - 540V (wide - range capture of solar power), with dual MPPT design and 1 string per MPPT (precisely track maximum power point even in complex shading or multi - module parallel scenarios). Value: From “small - scale residential” to “large - scale commercial”, and from “direct strong light” to “partial shading”, it ensures PV power generation efficiency in all scenarios and maximizes power generation revenue.
3. Compatible with Diverse Energy Storage: Fast, Accurate, and Stable Charging/Discharging
- Dual Battery Compatibility: Supports both Lithium - ion and Lead - acid batteries, seamlessly integrating with existing and new energy storage systems.
- Flexible Voltage & Power Regulation: Nominal Battery Voltage is 48V, Battery Voltage Range is 40V - 65V (compatible with different capacity/brand batteries); Max. Charging/Discharging Current ranges from 75A to 135A, and Max. Charging/Discharging Power reaches 4,000W to 6,600W (e.g., the SP6KL model achieves 135A/135A and 6,600W/6,600W, quickly responding to time - of - use electricity prices and power outage emergencies). Value: It is compatible with existing energy storage assets and efficiently supports scenarios such as “peak shaving & valley filling” and “emergency power supply”, making the energy storage system “easy to use, durable, and practical”.
4. Stable AC/DC Output: Reliable Grid - connected/Off - grid Operation with “Clean Electricity” Quality
- Grid - connected Mode: Nominal AC Output Power ranges from 3,000W to 6,000W, Max. AC Apparent Power is 3,300VA - 6,600VA; Output Voltage is compatible with 220V/230V/240V (suitable for global grids), Frequency is adjustable between 50Hz/60Hz, Power Factor >0.99 (@rated power), and Total Harmonic Current Dist.
