top 4 solar photovoltaic grid tie inverter features

Most grid tie inverters that are included in a solar electric system are over 90% percent efficient and include the following features:

  1. Weather Proof Enclosure – most grid tie inverters from Kaco Solar, Fronius, SMA, Xantrex, Enphase Energy and other major manufacturers are designed to be installed outdoors because they have weatherproof enclosures.
  2. AC/DC Disconnects – Newer grid tie inverters have built in AC/DC disconnects for safety and could have an over current protection feature. Some people like to add additional disconnects around the inverter to remove the inverter if it needs to be serviced.
  3. Ground Fault Protection – The National Electric Code (NEC) requires that roof mounted solar electric systems must be grounded. Most grid tie inverters have built in ground fault protection built into the inverter.
  4. Maximum Power Point Tracking (MPPT) – tracking the peak power point of a solar panel array is important to maximizing your energy harvest. Solar grid tie inverters on the market today take advantage of MPPT technology.

Are there any other features of a solar grid tie inverter that you think is important, that we missed on this list?
