A grid-tie kit feeds power into your home while the sun is up, which lowers what you draw from the utility. It shuts down in a blackout by design, so that line workers are not exposed to your power.
A power station does the opposite. It will run your fridge in an outage and it lowers nothing on an ordinary day.
Most people who arrive on this page want the first one. If you want backup as well, that is a second purchase, not a bigger version of the first.

- APsystems EZ1 microinverter — APsystems states it is “CSA Certified to UL3700 standards” (usa.apsystems.com, 15 July 2026).

Two systems, one job. For plug-in solar that feeds your home and lowers the bill, the head-to-head worth reading is EcoFlow Stream vs Anker SOLIX — two balcony systems doing that same job.
A different job: a portable power station is backup power for an outage. It is not a substitute for a grid-tie kit and it does not lower your bill. If that is what you are after: Anker C1000 vs EcoFlow DELTA 3 · C1000 vs C2000 · Anker vs EcoFlow at brand level
As of 2026, Indiana has no specific statewide law that names plug-in or balcony solar, so it sits in the same legal gray area as most of the U.S.: generally not banned, but governed in practice by your utility's interconnection rules rather than a clear state statute. With roughly average electricity prices, a plug-in kit delivers steady savings and a typical payback in the mid-single-digit years. In Indiana, residential power mostly comes from Duke Energy Indiana and AES Indiana, and their interconnection or notification policy is the real gatekeeper for a small grid-tied system. Before buying, confirm with them that a plug-in microinverter setup is permitted, stay within any wattage cap they specify, and choose a UL-listed (UL 3700 pathway) kit for safety.
Before you buy in Indiana
Call your electric utility and ask: (1) do they allow small plug-in / behind-the-meter grid-tied solar, and (2) is any notification or interconnection form required? Stay within the wattage they specify, use a UL-listed microinverter, and keep written confirmation.
Then estimate your numbers with our savings calculator (pre-loaded with Indiana's rate).
