    Weird idea for power outage

    Yes. But if you could buy a control box, PV Microinverters, and Battery Microinverter modules, you could create a highly scalable solution that could grow as your usage does. Each battery gets its own hybrid Microinverter, allowing mismatched voltages and capacities to still work together as a...

    Weird idea for power outage

    Scalability is a major sore spot for many possible use cases. For example, I only really need 2kw of emergency power. But the balance of system hardware required except the hybrid inverter itself is roughly the same up to the 12kw that would run almost all of my house. Unfortunately there...

    Using a generator interlock on an essential loads panel

    I am looking at installing a grid backup solution with or without PV attached, and noticed that many schematics show an inverter bypass circuit to operate the essential loads panel as a normal subfeed in the event that the inverter is down. Since my main panel is a Square D Homeline, I was...

    New NEC code makes it impossible for DIY systems to be compliant

    So, ESS must be compliant. For Lithium based technologies, I can understand why. Those technologies turn into a fireball if provoked. I'm not sure if I would trust a DIY battery assembly in this technology, even if I did follow a proven design. What of AGM and older technology batteries? They...
