Huawei Smart Energy Controller SUN2000-8 Single-Phase Residential Inverter

The Huawei Smart Energy Controller SUN2000-8 is an advanced single-phase residential inverter designed to optimize your solar energy system with high efficiency and intelligent features. Delivering 8,000W of power, this smart energy controller combines flexibility, reliability, and seamless integration with Huawei’s modular LUNA2000 battery system, making it a perfect fit for modern smart homes.

Advanced Technology for Efficient Energy Management

High-efficiency power conversion

The Huawei SUN2000-8 stands out with its great energy saving capabilities. Featuring 3 Maximum Power Point Trackers (MPPTs), it maximizes solar power harvesting by optimizing each solar panel string independently, even under varying sunlight conditions. This leads to higher overall system output, improving your home's energy efficiency.

This model achieves an impressive maximum efficiency of 98.1% and a European weighted efficiency of 97.5%, ensuring that the majority of the solar energy generated is converted effectively for use or grid feed-in. Its startup voltage is only 50 V, allowing earlier activation during low light periods, enhancing daily energy yields.

PV design and MPPT specifics

Extended specs: recommended max PV power 12,000 Wp; 600 V max input voltage; 40–560 V MPPT operating range; 3× MPPT / 3 inputs; 16 A max input current per MPPT (with 20 A max short-circuit current). These figures make string design flexible and future-proof for residential rooftops.

Seamless Integration with Modular Battery Storage

LUNA2000 compatibility & capacity

A significant advantage of the Huawei Smart Energy Controller SUN2000-8 is its compatibility with the LUNA2000 modular battery system, which supports capacities of 5, 10, or 15 kWh (S0) and 7, 14, or 21 kWh (S1). The inverter can deliver up to 8,000 W of charging and discharging power, allowing your smart home to enjoy reliable energy storage and backup. Battery operating voltage spans 350–560 V DC with up to 25 A operating current, and grid charging is supported for off-peak optimization or storm pre-charge strategies.

Charging strategies and autonomy

This capacity supports higher climate control efficiency by storing excess solar energy during the day and providing power during nighttime or grid outages, reducing your dependence on external power sources and increasing self-consumption rates.

Reliable Safety and Durability Features

Protections and certifications

Safety is a crucial aspect of any solar inverter, and the SUN2000-8 includes multiple protections such as integrated AC and DC overvoltage protection (Type II), ensuring the system's integrity in fluctuating electrical conditions. It also comes with a 10-year warranty, underscoring Huawei’s confidence in the product’s long-term reliability.

All-weather design and warranty

The inverter is built to endure a wide temperature range from -25°C to +60°C and humidity from 0% to 100%, making it suitable for diverse climates and operating conditions. Its IP66 protection rating prevents dust and water ingress, ensuring durability in outdoor installations. Additional safeguards include anti-islanding, DC reverse-polarity protection, insulation monitoring, residual current monitoring, AC overcurrent/short-circuit/overvoltage protection, over-temperature protection, and AFCI protection.

Intelligent Connectivity and Easy Monitoring

Communications and app monitoring

Equipped with communication options such as integrated WLAN, RS485, and optional Smart Dongle-WLAN-FE (WLAN/Ethernet) or Smart Dongle-4G modules, the Huawei Smart Energy Controller SUN2000-8 enables remote monitoring and control via Huawei’s FusionSolar platform. LED indicators aid quick on-site checks. This home automation feature allows users to monitor system performance in real time, track energy generation, and diagnose potential issues promptly, bringing true convenience to homeowners.
