Central inverters are for applications such as large string arrays on buildings, industrial facilities as well as field installations. Supplementary panels are installed and connected with their own micro inverters. That much energy can offer huge savings on your energy bill. 6. Microinverters offer greater flexibility when it comes to system design and installation. Microinverters tend to be more efficient than inverter optimizers, meaning that they will produce more power over the system's lifespan. Note that the Vmp of the solar panel must be MPPT range, to enable adequate output efficiency. I would be very reluctant to put 20 inverters up on a job rather than putting one string inverter. Solar Inverters. 1. $1,388.13. Both add up to 20% cost to an installation. The micro-inverters, despite being a lot more expensive, have a 25-year warranty and an average lifetime 32 years! How Microinverters Work. This is the best micro-inverter on our list, and that is why we reviewed it first. Each microinverter fully handles the DC-to-AC electricity conversion for one solar panel. So, Microinverters have a slightly greater up-front cost than central inverters. This inverter has a high-performance automatic power point tracking (MPPT), and it can generate power with an efficiency of up to 99%. Additionally, micro inverters provide the option for additional panels to be added in the future should your needs increase. In contrast, if you have a traditional string inverter, enlarging your system means adding a second inverter. The new IQ7 Micro Inverter line from Enphase has proven to be reliable in the Central Texas Heat. Basically, a string inverter connects a whole solar array to the grid at once, while micro-inverters connect each individual panel, making installation and monitoring a simple and accurate process. Add to Cart. It offers a continuous wattage of 900 watts and a peak wattage of 1,000 watts. To understand how a micro inverter works, it helps to understand its role in solar energy production. The micro-inverter technology directly combines the inverter with a single photovoltaic module to equip every photovoltaic module with an inverter module which is capable of DC-AC conversion and the MPP tracking. 1. String inverters are yes, less expensive, but they only have a 10-year warranty and do not have a high life expectancy. String Inverter Solar Vs. Microinverters vs. Optimizers.
