Embarking on a fresh individual style which is no longer characteristic of a cloned SMA, Goodwe has evolved to flex some individual identity finally. Question marks though often always surround entry-level products from Chinese manufacturers, and make no mistake, the Goodwe brand competes at the relatively affordable end of the spectrum. However, could the Goodwe DNS series finally be the more economical solar inverter to get excited about?

.Make and model:  Goodwe DNS.

Variants: 3.0 | 3.6 | 4.2 | 5.0 | 6.0.

  New design, Respectable performance.

  Limited features, Guarantee.

The only way had to be up for Goodwe in their most popular residential inverter classification. With a redesigned 3-6kW inverter model, Goodwe is now acquiring an identity which no-longer rides off the success of alternative industry influencers. As the industry edges towards a new solar inverter and energy storage control evolution, has Goodwe done enough to earn the trust of an industry with too many vulnerabilities?

Six common traits exist between modern solar inverter technologies. As such, comparing the Goodwe DNS Series against the industries best specifications in design, features, performance, guarantee, software and affordability outlines a better perspective of the Goodwe DNS Series place within a competitive market.

Design.

The new release white gloss exterior is a breath of fresh air for those seeking a more aesthetically pleasing design from their solar inverter. With no battery input terminal, the Goodwe DNS Series is battery compatible through either AC or DC coupling. Fanless design ensures low noise cooling via natural convection. Able to be mounted both indoors and outdoors the Goodwe DNS Series holds an IP65 weather rating. As with any inverter, areas exposed to direct sunlight should be avoided. 

With no individual award related explicitly to the Goodwe DNS series, the Goodwe brand as a whole is slowly acquiring praise from certain industry guilds. General build is one notch below inspiring as a very standard inverter design compared to alternatives available.

  • TÜV Reihnland certified.
  • Standard.
  • IP 65.

Features.

Featuring the now expected dual maximum power point tracker (MPPT) DC input, the Goodwe DNS Series can make the most of 2 alternative roof aspects without detriment to the other. The most debatable feature though as we head into a new era of solar inverter technologies is the LCD interface. As the most significant failure point in many inverters, manufacturers on the forefront are now adopting a modern multi-function LED interface with local app connectivity (no internet required) for instant inverter readings and fewer points of failure. To assist with ease of communication the Goodwe DNS series possess a WiFi communication module for wireless communication and an RS485 port for fixed line communication.

Less than desirable there is no inbuilt DC isolator, no optional manufacturer module-level optimisation capabilities and no manufacturer supplied module-level rapid shutdown capabilities. Features possessed by alternative makes which reduce the versatility of the Goodwe DNS Series in specific scenarios. With the release of the new Goodwe Smart Meter, there is, however, manufacturer supplied expanded monitoring capabilities. Consumption monitoring is almost a necessity with any system and the key to energy saving success.

Performance.

Surprisingly, the Goodwe DNS series performs very well in comparison to the industry’s best specifications. A respectable 97% European efficiency is further complemented by a wide operating temperature window of -25°C to +60°C. Complimenting the intended mounting location weight is a minimal 13kg. Those sensitive to noise it must be noted there is an acute operating noise of less than 25 dB(A) which is less than most.

  • 97.5% European efficiency.
  • Temperature range of -40°C (-40°F).
  • Temperature range of +60°C (140°F).
  • Temperature derating of 45°C (113°F).
  • Weighs 25 kg (55.1lbs).
  • Noise emission of 25 dB (A).

Guarantee.

The most underwhelming feature of the Goodwe DNS Series inverter is easily the warranty. 5-year parts and 5-year labour warranty goes fast when buying a solar energy system built for long-term results and environmental sustainability. The upside is that including an additional 5-year parts only warranty (total 10-yr parts coverage) is relatively inexpensive although not included in the base product offering. 

The least desirable aspect of the Goodwe DNS series guarantee is that there is no manufacturer trained installer network. Essentially, any installer can install the product without full knowledge of the Goodwe DNS Series solar inverters specific installation requirements to ensure secure warranty and extended life. When not installed to manufacturer specifications the warranty is void.

Affordability.

A big reason why many would consider the Goodwe DNS Series is the affordability of the technology at hand. The technology is not of the highest standard as alternatives. However, the price based on the technology offering makes this inverter an attractive choice for a good reason. Those with limited budgets could do far worse.

OVERALL.

The Goodwe DNS Series is not the best single-phase residential inverter in the world. What it does offer though is excellent value from a hugely evolving brand if installed correctly. With an abundance of future-proof compatible battery inverter options, the Goodwe brand potentially has one of the most rapidly growing inverter technology ranges available. The negative to this is more often than not a lack of refinement in the final product. The new Goodwe DNS series is a respectable variant of an entry-level, single-phase, 3 – 6kW inverter range ideal for those wanting to enjoy the benefits of solar but reserved regarding cost.

Tip: Upgrade the product warranty to 10-years purchased as an add-on at the time of sale. Worth the small additional extra cost.
