The Basics
The Power Grid and You
SkyBox is designed with four AC profiles. Each profile interacts with the utility grid in a different manner.
In all of the AC profiles, no battery power will be supplied to the site when the battery reaches
Minimum SOC
(state-of-charge). This means if there is a power outage and you drain your battery to this low setting, your
refrigerator, freezer, wifi, etc. will be off until the utility power returns or the battery is charged.
Sell for All You’re Worth (Net Metering With Backup)
When the Net metering with backup profile is selected, the SkyBox harvests as much solar power as it can.
After sending power to your protected loads, all extra power will be sent to the utility.
Protected loads are those household items needing electricity to run that you’d rather not lose during a power
outage. This usually includes things like your freezer, refrigerator, internet router, etc. If the load demand (the
amount of electricity needed to run all those things) exceeds the available solar power, the SkyBox will buy
power from the utility to cover the difference.
IMPORTANT:
This is the ONLY profile which functions correctly WITHOUT a battery installed.
When running in a standalone fashion
(without a battery), the SkyBox operates
like any other grid-dependent inverter.
Solar power is produced, harvested,
and sent to the utility while the utility is
active (no power outage). During an
outage, the SkyBox shuts down and no
solar power is harvested.
When paired with batteries, the SkyBox
keeps the batteries full. This ensures
that when power goes out, your lights
stay on for the maximum time. Ideally,
your installer (or you, the installer) sizes
the system so this maximum time is an
entire night of protected loads. This
assumes the sun is available the next
morning and solar power takes over,
allowing the battery to take a break.
This profile is best used when the utility
is normally stable and only short
interruptions are expected.
