Inverters: What you should know
Inverters are not always the first thing that comes to mind when considering adding solar to a home or business. But an inverter chosen for a PV system is equally as important as the panels. Below we will go over the advancements in inverter technology, and explain why NM Solar Group uses the best solar inverters on the market.
Differences in Solar Inverters
String inverters were the original system to change DC energy (raw energy) to AC energy (the energy that prominently runs through your home). The problem with string inverters is they are like Christmas lights. They can only produce power to the lowest current, so any shading on a panel or a lower producing panel effects the entire system.
Then came the micro inverter. Leading the charge was phase, AP systems, and behind that was Solar bridge micros. They change DC energy to AC right at the panel. Allowing clients to see panel for panel monitoring and allowing installers to use many different planes for installs.
Solar Edge came in after and changed the game. Please reference their stock price compared to enphase or the owner of Solar Bridge Sunpower. Solar Edge took the best of both worlds. Parallel or each panel independently operate and they send DC energy down to a central inverter making it cheaper and easier to add a battery. Each optimizer still allows you to monitor the panels individually but it also helps each panel to produce the optimal amount. The largest transfer or loss of energy happens when DC gets changed to AC. Doing that that inside of a garage or on a shaded side of your house is much more efficient and better for the electronics than doing it on the hot roof.
At NM Solar Group
we chose to use Solar Edge with optimizers because we believe in doing what's best for our clients and making sure their systems run properly as long as possible.
