A solar inverter is a device that transforms DC battery or solar panel voltage into mains type AC power; suitable for use by regular appliances. A solar inverter is an integral part of a system, but attention to this aspect is often overlooked. You can have the best solar panels available, but if your solar inverter is of poor quality, overall system performance can be greatly impacted. Similar to any other component in the solar power system, the inverter has an optimal operational window within which it performs at its most efficient point. With respect to the graph above, where the red-line represents an average inverter efficiency and the green arrow suggests the size of power output from your solar panels, the grey box becomes the operational window of the inverter based on the input from the solar panel and the predetermined inverter efficiency.
TRIO-5.8/7.5/8.5-TL-OUTD 5.8 to 8.5 kW
The all-in-one, residential, three-phase TRIO-5.8, 7.5 and 8.5 kW inverters deliver performance, ease of use and installation, monitoring and control. With their 98% peak efficiency and wide input voltage range, these new residential TRIO inverters mean flexible installations and powerful output. Commercial grade engineering at residential scale. These new additions to the TRIO family are small, light and built smart. The topology of the larger, commercial TRIO inverters has been redesigned to ensure that the TRIO-5.8/7.5/8.5 models also enjoy high conversion efficiency across a wide range of input voltages. Optional integrated Dataloggers and smart grid functionality, remote firmware updating and elegantly simple sliding front covers make these all-in-one devices easy to install and maintain. In short, they are commercial grade engineering at residential scale.

Sungrow SH5K PV ESS
In many countries, with the rising popularity of solar energy and its essential PV systems, the feed-in tariffs of PV power have dropped considerably. Nevertheless, the average electricity prices are still growing at a rapid rate, resulting in increasing burdens on the households. Electricity used in peak times can place a strain on the grid network, that is why energy providers charge a relatively larger amount for its service at peak time. As such the peak time service fee tends to be higher than the cost of actual usage.
