We sell two main inverters: Enphase and SolarEdge. Below is some information about each of them – feel free to contact us with any questions!
Enphase Energy manufacturers microinverters. The company has been a key part of the solar industry throughout the last decade. They released the first microinverter in 2008 and have since seen a lot of success in North America. They also offer a 25-year warranty on their product.
Because Enphase makes microinverters, each panel has its own inverter. This means that if half of the panels are in the shade, the ones in the sun will still operate at full capacity. (With string inverters, the whole system only operates as well as the least functional panel. This means that if shade covers half the panels and reduces their output, the rest of the panels will also operate at a reduced capacity).
Enphase inverters are NEMA 6 certified, meaning that they are certified to be able to handle harsh and inclement weather. They are tested in high temperatures in Australia, so they will certainly be able to handle any heat New England throws at us! Enphase inverters are also equipped to handle situations that might caused reduced output such as shading, soiling, individual panel damage or degradation, and unideal roof layout.
Additionally, because of the customizable microchip in their inverter, Enphase make it easy to expand a solar panel system and add more wattage. However, because of the technology that comes with the increased efficiency of microinverter, Enphase inverters are more expensive.
SolarEdge offers a string inverter + power optimizer system. This system gives some of benefits of microinverters to string inverters. For example, SolarEdge inverters are capable of system monitoring at each panel. Additionally, shade on one or two panels does not affect the output of the whole system. SolarEdge inverters also include a safety feature that allows them to be shutdown down quickly in an emergency situation.
SolarEdge has single phase and three phase inverters. The single phase range from 2.2 kW to 6 kW, and are mostly for residential use. The three phase range from 4 kW to 33.3 kW and are often for commercial and industrial sites.
SolarEdge inverters are small and lightweight. Since string inverters tend to be cheaper and simpler than microinverters, with SolarEdge you can get lower costs than you would buying an microinverter. The power optimizers on a SolarEdge system allow you to easily expand a solar panel system and add more panels if necessary. SolarEdge also offers a 12 year warranty on their product.
There is a lot to think about when considering which inverter is best for you. Feel free to reach out and contact us with any questions, and to get a free solar quote so we can tell you what we think will suite your solar needs.
