A specialized inverter receives power from your solar panels and converts the DC voltage they produce directly into grid-compatible AC power. The grid-tie inverter enables your home to not just import power from the utility, but export power to the utility as well.
[pdf] The inverter topology fundamentally determines its capabilities: Central inverters: Process aggregated DC power from multiple strings, offering cost efficiency but limited MPPT granularity. String inverters: Balance performance and cost by handling 1-4 PV strings with individual MPPTs.
[pdf] Prices typically range between $2,800 to $4,500 for quality units as of Q3 2023. But wait, no – that's just the inverter itself. Installation and configuration could add another $1,200-$2,000 depending on your roof's complexity.
