FAQ: What is a GridFree Solution
Question: What is the difference between the GridFree and the Grid-tied installation?
There are basically just two possible types of installations: Grid-tied and Off-Grid.
The grid-tied installation means the inverters work in synchronization w
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 micro
Understanding the EN 50438 for MicroInverter Operation
The EN 50438 gives the specifications of the Grid parameters. The microiverters are required to operate within the limits of this EN standard.
The parameters mean if the grid frequency is above 52 Hz or bellow 47.5 Hz, the microin
Small solar panel with the solar micro-inverter
Question: I have a 185Wp panel. How will this panel work with a 250Wp microinverter?
Answer: The panel will work with the microinverter only if the voltage of the panel matches the operating voltage of the inverter. If the voltage matches,
FAQ: Multiple micro-inverter installation
I have a microinverter installation with products from ABC Company. I have 2kW installation (8x250Wp). Now I wish to increase my installation with more inverters. My questions:
1) The products from ABC Company use a PLC communication to work
Micro-Inverter – Combined Energy at Your Hand
Combining the existing water/wind power plants with additional energy supply from solar panels.
Smart energy handling with solar micro-inverters, especially for small water power plants: if there is a lot of sunshine, usually th
Micro-Inverter – Solar Retrofitting
Adding additional permanent or temporal modules to increase the yield of the solar installations. Increase the yield from your existing solar installation by simply adding one or more extra solar panels with microinverters.
Micro-inverters: More Energy From Shaded Panels
Some roofs may have a partial shading - prom chimneys, from parts of tries. With central inverter such partial shading will completely degrade the performance of the whole solar installation. With microinverters the shading is limited o
