When it comes to installing and setting up your solar inverter, just know that setting up a grid-tied model is much easier than an off-grid one. To connect a grid-tied solar inverter, all you have to do is to hook it up to your solar panels using the necessary wiring. Installing an off-grid solar inverter is more complex because it incorporates a battery where the energy is stored and a charge controller. While it’s not overly complicated to wire the inverter, battery, and solar panels, it will take substantially more time to do so.
