Benefits Hybrid Inverter GoodWe ET50 GW50K-ET-10

The leap of residential power to commercial is usually forcing several inverters in waterfall or to resort to container storage systems, with a much greater cost and complexity. The GW50K-ET-10 covers that hole with 50kw hybrids in a single mural equipment of 65 kg and just 26 cm in the background. Is a compact alternative within the range of inverters hybrid for ships, businesses, hotels, agricultural holdings or energy communities that need storage without occupying a technical room.

More battery power than AC output

One of the most striking data on the file is that the power of loading and Battery Download Reaches 55KW, above the 50kw nominal of exit With 100A continuously at a tension between 200 and 800V, the inverter can absorb solar production peaks towards lithium batteries o Download them quickly to cover a demand point. The efficiency battery to AC of 97.7% reduces losses in each cycle, something decisive in C & I facilities that cycle the battery daily. GoodWe it poses it as a complete solution next to its battery system GoodWe Lynx C, although it is compatible with a range of capabilities.

Four modes of operation to make the battery profitable

ET50 is not limited to self-consumption. Your smart ways allow you to adapt the strategy to each company's profile:

• Own consumption: prioritizes the consumption of solar energy in the building itself.
• Peak Shaving: trim the demand tips from the battery to reduce the contracted power and avoid excess power.
• Time discrimination (Time-of-use:) charging the battery in the cheapest periods and the download on the most expensive, a very cost-effective strategy with the rates of six periods usual in the tertiary and industrial sector.
• Network support: it incorporates support functions to the electrical network.

Parallel scalability and level backup UPS

The ET50 series admits parallel connection both in installations connected to network and isolated, which facilitates expanding power in a modular manner. For the backrest, the team is combined with the STS Box (Static Transfer Switch), which enables a switching level UPS to backup. With it, the three-phase emergency exit delivery 50kva nominal, , 60kva for 60 s and 75kva for 10 s, sufficient to tear compressors, pumps or machinery with high start currents.

Commercial grade protection

The GW50K-ET-10 equips protection against Type II overvoltages Both in CC and AC, with the option to expand the DC side to Type I + II in areas with high risk of atmospheric discharge. Its envelope IP66, the work range of -35 to +60 ° C and a maximum altitude of 4,000 m they allow you to install it abroad, next to the cover or the general box.

Warranty

The manufacturer's technical sheet does not specify the warranty period of this model. Consultation with the commercial team of Tienda Solar the current conditions and the support available for C & I projects.

Photovoltaic field design with 4 MPPT

A FV entry designed for industrial covers

With 4 MPPT and 2 strings by MPPT, the GW50K-ET-10 accepts up 8 strings. Two of his followers admit 42A and the other two 32A, an asymmetric configuration that gives margin to connect two strings in parallel of solar panels high current in the highest capacity inputs. The FV power can reach 75kw, the 150% of the nominal.

Spacious MPPT range for complex covers

The tracking range goes from 165 to 850V, with start 200V and nominal voltage of 620V. This allows to combine skirts with different orientations, inclinations or number of modules without penalizing production, something usual in ships with skylight, chimneys or partial shade areas. Select the structures for solar panels suitable for sheet metal, sandwich panel or flat cover.

Monitoring and energy control

Communication with the counter RS485 it allows to apply injection control and Peak Shaving with precision. The connection to the portal is carried out by LAN or, optionally, by 4G, an advantage in rural sites without cable internet access. The adjustment of the power factor between 0.8 capacitive and 0.8 inductive it also helps to manage reactive energy.

Is the GoodWe ET50 suitable for my project?

The GW50K-ET-10 fits into companies with high daytime consumption, high hired powers or need for cutting-ups. If the project does not require storage, you can value alternatives in Inverters Networking. For residential powers, the range of inverters solar includes smaller hybrid models. And if you want to deepen Peak Shaving Strategies, Six-period Rates or Dimensioning Batteries for Business, in the Blog of Tienda Solar you will find guides and technical items prepared by experts.
