Solar power is an alternative form on energy. Part of your solar powered system will include an inverter. There are micro inverters and string inverters. There are advantages and disadvantages of each type. I want to educate you about string inverters.
String Inverters
String inverters have been around for a long time. A series of modules are connected in a series to produce a large amount of high voltage. This array is then connected to an inverter which converts it to AC for house use. There is energy maximers that can enhance the power produced from a string inverter. These can increase the output of your array. If you have ideal area with no shading, the string inverter is definitely the way to go. If there is shading, it will affect the output of the system. If for some reason one of the modules has a defect from the manufacturer that causes it to produce 5% less, the string as a whole may produce 5% less. If there is a problem with one module, it may cause the array to go offline.
Stringers have very little electronics in them. They have a diode which is directional. For ground mount or pole mount system, installers should definitely consider a Solar Edge or an Enphase on the ground because it is more accessible. The solar installer can get to the back of each module from the ground to replace it if needed.
One homeowner has a string system or string inverter on his house with an SMA inverter. SMA has designed and built systems that are easy to use. They are going to a system similar to the Solar Edge system that would have software. This software will tell you when one module is out. I am in favor of that but not in favor of it on your roof unless it is installed 6" from the roof so that the heat can dissipate. But using black modules? I'm still not decided on that yet. I'm certain of the heat damages but I'm not certain of the modules being able to keep up for many years to come. I know the string inverters (Enphase and Solar Edge) are built with heat sinks built right into them to dissipate heat.
The first problem - as mentioned above - is that you might not have 100% of the modules. The second problem is if you want a charge controller. You can forget it on Enphase. You can forget it on Solar Edge. What they are doing is feeding what power there is and designating it to the inverter. So you can't use it when it's charging batteries or using a charge controller. You can only use it for a grid-tie system. Some systems can be built-in case I want to go off the grid. Homeowners need to plan ahead.
