Micro-Inverter

For all that solar electricity can look like the stuff of science fiction, and for all that the technology can get very complicated in many ares of detail, when you consider rooftop solar photovoltaic systems on their most comprehensive amount they are actually remarkably simple. There are only minor elements to contemplate, like wiring and railings for the panels.

Micro-Inverter

Fairly straightforward stuff. So what’s this company about micro-inverter? What does it do? Why does it matter?

The micro-inverter sits at the center of your rooftop solar system. It requires the electricity that your solar panels create, and shifts it into a form that the lights and appliances can use. Without it, your panels are useless for the intent of running your home.

Solar panels produce a low voltage DC output. Your fridge, your tv, and your computer were all assembled for high voltage AC electricity, also called “mains power”. Solar panels can not produce mains electricity on their own. They need a helping hand. Some micro-inverters will even provide a continuous voltage DC output signal that is low, to devices. This can be generally of small use to the typical dwelling, but can be useful for running to run the low voltage circuits discovered on houseboats or camping equipment. Some micro-inverters can even output AC power at voltages above regular mains electricity, which is useful for those who have commercial or industrial equipment set up to use 3 phase power.

Any solar micro-inverter’s largest and most noticeable attribute is the micro-inverter’s rating. That is only a measure of how much power it can take out of your panels and supply to your home. There’s absolutely no point putting 20 300 watt panels on your roof

Solar micro-inverters also play a role in ensuring that your photovoltaic panels produce just as much power as they can, through a process known as “Maximum Power Point Tracking“, or MPPT. Solar panels will provide differing numbers of electricity and the amount of resistance needed to provide the maximum amount of power can depending upon the temperature and level of solar irradiation the panel receives. Through MPPT, the micro-inverter will determine what load to put on the panel array to supply the most power given the conditions that are prevalent.

Some micro-inverters will have greater than one MPPT tracker, permitting a different load to be placed on distinct groups. If the layout of your roof requires one to place your panels in different arrays, a double MPPT micro-inverter may be very useful in ensuring your panels perform at their greatest. This is especially true when the panel arrays are angled differently or face distinct directions. The operation of your system will be dramatically affected by joining a single MPPT micro-inverter to panels placed on areas of the rooftop facing in different directions. A dual MPPT micro-inverter can also supply some incremental advantage to a group of panels all facing the same way at the same angle, in cases where some of the panels are likely to experience temperature variations, or some might be partly shaded at specific times of the day.

Solar micro-inverters also frequently play a part in reporting your system’s functionality. This can be useful in monitoring the yield on your own investment from going solar. Some micro-inverters hook into your home’s wireless network, so that it is possible to log in and have a gander at how your system is doing from your smartphone or your computer.

Some systems have a small micro-inverter attached to each panel – this is known as a “micro-micro-inverter”. This can be useful for many applications. It also means that arrays of solar panels can be added to or downsized over time, as on-site power demands change. It further means that less will go offline in the event of equipment failure.

Selecting the correct micro-inverter for your circumstances is critical to your system’s functionality, and to ensuring that you simply get the greatest yield that you can on your investment.
