A solar inverter costs $2,000 on average, with prices often ranging from $1,000 to $3,000. That said, some homeowners spend as little as $800 or as much as $5,000.
The chassis must be grounded through the equipment grounding conductor. The key rule involves the neutral-to-ground bond: Only one bond point avoids parallel paths and GFCI issues. The inverter becomes the source and must set a stable reference.
