In the early days, a grid-connected solar inverter had one job, to convert solar-generated DC energy into useable AC electrical energy. Today, the expectations of one single device are much more. The recent release Huawei SUN2000L solar inverter range makes an effort to define itself as an innovative option for those seeking greater value in a solar energy system.

What can the Huawei SUN2000L range of solar inverters do which most mainstream solar inverters can’t? Considerably more. However, depending on what you expect, prepare for a mild level of disappointment.

As with every inverter technology, the Solar Review Inverter Assessment Criteria considers the five critical elements of the selection process; Design, Features, Performance, Guarantee and Software. With the available information, determine whether the Huawei SUN2000L solar inverter is the right solution for your energy production needs.

Design.

Reddot design awarded 2017, Huawei has unquestionably developed one of the most innovative solar inverter designs in recent years. Contained within a minimalist exterior are features unmatched by previous leading solar inverter models in the same category.

With an end-users energy future in mind, the Huawei SUN2000L inverter can integrate with a superior solar battery option in the form of the LG Chem RESUH range. Potentially the most disappointing element though for anyone anticipating battery connectivity is the absence of an emergency power supply (EPS) function in the event of a grid failure.

Beyond battery connectivity, a reduced copper, fan-less internal construction ensures Huawei SUN2000L solar inverters are virtually maintenance-free with no moving parts. A corrosion-resistant aluminium housing protects internal componentry from dust and water elements accompanied with an IP65 protection rating. Overall innovative, the Huawei SUN2000L design is changing end-user expectation of what a solar inverter should do.

Huawei Sun2000L Inverter - Solar Review

Huawei

SUN2000L Design; SUPERIOR
  • Hybrid solar & battery inverter without EPS.
  • LG Chem & Huawei (HV DC Coupled) battery compatibility.
  • New release.
  • Fanless.
  • Reddot Award 2017.
  • TÜV Reihnland certified.
  • Innovative.
  • IP 65.

Features.

Beyond DC-coupled battery connectivity, the Huawei SUN2000L range can incorporate module-level optimisation options immediately, or in the future with Huawei’s module-level optimisation technology. Tripling up Huawei’s optimiser technology can act as a rapid shutdown feature (if required) or a module-level monitoring device for advanced system management.

One up on competing inverter makes, internally integrated (AC & DC) surge arrestors aid protection from voltage variables. As a dual-tracking inverter, the in-built DC isolator switch is a bonus for some areas of the world. Combined with a multifunctional LED signalling interface, full energy visualisation is achieved through the Huawei FusionHome software. To aid communication, inputs exist for both Ethernet, 4G (extra) and WiFi internet communication.

Huawei

SUN2000L Features; OUTSTANDING
  • 2 MPPT.
  • Multifunctional LED display.
  • WiFi & Ethernet (plus 4G optional).
  • Manufacturer supplied module-level optimisation options.
  • Manufacturer supplied rapid shutdown options.
  • Manufacturer supplied expanded monitoring options.
  • MPPT only shadow management (Optimisers optional).
  • Remote operational parameter support.

Performance.

Huawei has developed a world-first, patented 5-level topology ensuring reduced copper componentry and therefore boasting fewer electrical losses. With this in mind, the Huawei SUN2000L solar inverter range possesses a maximum efficiency of 98.6% (98% European weighted efficiency).

-30°C to 60°C is a broad operating temperature range derating only after 55°C. The Huawei SUN2000L is a surprising performer for diverse environments. A continuation of the remarkable performance features includes an outstanding weight class of a mere 10.4kG and a noise emission rating of less than 25 dB(A).

Huawei

SUN2000L Performance; ELITE
  • 98% European weighted efficiency.
  • Min temperature range of -30°C (-22°F).
  • Max temperature range +60°C (140°F).
  • Temperature derating 55°C (131°F).
  • Weight 10.2 kg (22.4lbs).
  • Noise emission max 25 dB (A).

Guarantee.

As of July 2019, the Huawei SUN2000L solar inverter range boasts a full 10-year parts and service warranty in selected regions of the world. A more comprehensive warranty solution to the 5+5-year warranty common amongst alternative inverter manufacturers.

What diminishes such a comprehensive guarantee ranking? The absence of an authorised installer network with additional end-user benefits. Authorised installer networks provide greater product awareness and ensure the product is installed to manufacturer guidelines for peace of mind warranty assurance.

SUN2000L Guarantee; SUPERIOR
  • 10-year parts warranty.
  • 10-year service warranty.
  • No authorised installer network.

Software.

User-experience and technical information continue to be areas where the Huawei FusionSolar portal requires attention. Even though FusionSolar displays essential energy generation information, this potentially is one of the more lacklustre monitoring portals a user is likely to experience.

Given the Huawei SUN2000L’s recent release to market, such software deficiencies are forgiven in the short-term. Software design for hardware manufacturers such as Huawei will always be secondary to the product. See the full Huawei FusionHome monitoring software review for more insight > (Coming Soon).

Huawei

SUN2000L Software; VERY GOOD
  • Huawei FusionHome monitoring software.
  • iOS & Android app.
  • Alerts & fault diagnosis.

OVERALL.

Certain solar panel array design limitations are present when looking to pair the Huawei SUN2000L with the LG Chem RESUH solar battery. Additionally, despite the inclusion of a high voltage battery input terminal, Huawei SUN2000L solar inverters do not provide emergency power supply (EPS) functionality from the battery in the event of a power failure.

If backup power and the rare solar array design limitation are a non-issue, understand that Huawei has produced a technically superior and innovative solar inverter technology many competitors will seek to better in the not too distant future. The Huawei SUN2000L solar inverter is an overall SUPERIOR solar inverter option many should consider presenting outstanding value for the technology at hand.

7 COMMENTS

    • The Huawei SUN2000L range is compatible with the LG Chem RESU HV range of solar batteries only through the DC battery input terminals. Expect additional compatibility with a new Huawei HV battery to be released in 2020.

  1. I have 7.5kW of monocrystalline solar panels on 2 x strings. The existing 3 phase inverter is an INVT. I would like to update to a hybrid. Can you please assist and supply me with a model that would accommodate my system.

  2. Have a huawei inverter just 1 year old faulty have been waiting nearly a month for warranty replacement and have heard nothing still waiting so far not very impressed
