Objections

    From 3 comments
    • It looks beautiful. But I honestly don't understand what the market is. OP answered in one of the comments that it will run a single fridge for 32 hours. I understand the…

    • I don't understand this. It's a tiny backup battery with an expensive enclosure, with only 100W of solar input? How are you expected to run solar wiring with this in your living…

  • Plug-in backfeed and solar wiring raise safety and practicality concerns

    From 2 comments
    • Two questions: 1. Have you considered building a “microgrid interconnection device” to go with this to allow the batteries to backfeed a house in the event of an outage? (This…

  • How islanding works and whether grid-side install is needed

    From 1 comment
    • This looks great! > When an outage happens, the onboard inverter detects the power loss within 20ms and automatically disconnects from the grid (islanding) How does this work? Do…

Alternatives named

  • Standard UPS units

    From 2 comments
    • So it's just a smarter UPS, (that can integrate with solar panels) but you only compare it to a standby generator. Seems like you need to compare it to a UPS too, because that's…
