FAQ: Adding the solar microinverter to the central inverter
FAQ: Adding the solar microinverter to the central inverter
Question: I have a permit to connect a 2 kWp solar installation. At this time I have a 1.5 kW inverter. I consider connecting another set of two 250Wp panels with microinverters to increase from 1.5kW to full power of 2 kW. Are the microinverters from GWL compatible with my solar inverter? Will they work together?
Answer: Yes, these inverters will work together on the 230V AC line. They all work on the same AC line and they follow the same international standards (in EU defined by EN50438 norm). So it is possible and very easy to “mix” various inverters on the AC line together.
Your idea is very clever and we recommend to all customers: With microinverters it is possible to add additional solar panel or panels to the existing installation (with other inverters) to get the full maximal power peak that is permitted by your grid license. As there is no change of your original installation, there is no need to update your license or permit from the Grid operator. This expansion of existing solar installations is also called solar retrofitting.
