The 3-5kW Single Phase GoodWe NS Solar Inverter for Self-consumption Grid Injection is a device that allows us to convert the direct current provided by the solar panels of a photovoltaic installation into alternating current with single-phase output for the consumption of the home, commercial premises or small industry.
This type of inverter is the simplest and most economical because they only work when they receive sunlight. They are connected to the mains and generate a signal of the same frequency to be able to inject it. Grid-connected inverters are specially designed for installations where most of the electricity consumption takes place during the day. At night, when there is no power generation, the inverter will remain off. The next day, when the sun shines, it will automatically switch on.
Grid-connected photovoltaic systems are the most cost-effective because they provide savings on the electricity bill with a very low investment. Energy traders have surplus energy compensation systems to be able to sell surplus energy. If you wish to block the surplus energy produced by the inverter, you will need to purchase a monitoring and zero discharge kit, which is sold separately. By blocking the surplus energy the inverter is no longer connected to the grid and commissioning would be much quicker as it would no longer require the approval of the Ministry of Industry or the Inspectorate of the regulatory body.
Features of the 3-5kW Single Phase GoodWe NS Solar Inverter for Self-consumption Grid Injection
The GoodWe NS series stands out for its small size and can be installed almost anywhere. It has IP65 protection so it can be installed both indoors and outdoors. It also features a low start-up voltage (80V DC) of the MPPT tracker. The MPPT tracker (Maximum Power Point Tracking) makes sure to find the point where the solar panels generate the maximum power output. It is able to achieve very high efficiency.
It allows connection via Wifi and RJ45 LAN cable which is purchased separately. Thanks to the SEMS Portal, you can monitor the production of the solar plant. If you want to monitor both the solar production and the consumption of the house, you will have to purchase the Smart meter, which is sold separately.
