Keeping Your Battery Alive and Well
IMPORTANT:
The minimum allowed battery voltage is 42 Vdc. The SkyBox will not connect to a
battery below 42 Vdc. A battery discharged below this level must be charged from an
external source.
Battery Types
Many batteries have been tested and are compatible with the SkyBox. Each choice in the drop-down menu
loads the SkyBox with the correct charging voltages for each battery. All that is needed is to tell the SkyBox
the number of paralleled items (strings) in the energy storage system.
Given the increasing popularity and variety of lithium-ion batteries now available, it is important to clarify the
interoperability and safety considerations for pairing these batteries with OutBack Power inverters and charge
controllers. Lithium-ion batteries present different safety risks and performance impacts than the lead-acid
batteries many of our products were originally designed around. For this reason, OutBack Power has adopted
a white-list approach to battery interoperability. The Compatible Batteries list (
) includes batteries that
have been reviewed and tested by OutBack Power personnel and whose manufacturers have provided specific
guidance on equipment settings and limitations. Use of batteries not on this list — including unlisted battery
models from the same manufacturers — is at the risk of the installer and host site and may result in your
warranty being void. This remains the case regardless of any technical advice or assistance that may be
provided by OutBack Power, its personnel, or representatives.
Please refer to the application notes (
) and any manufacturer recommendations for recommended
settings. Note that inclusion on this list does not constitute an endorsement of these battery products and that
not all combinations carry the safety listings required by some permitting authorities.
PLEASE NOTE THAT OUTBACK POWER DOES NOT CLAIM RESPONSIBILITY FOR ANY DAMAGE DONE
BY OR TO BATTERIES THAT ARE DEPLOYED USING THE INFORMATION FOUND IN THIS NOTICE.
What if you’ve chosen to add energy storage later? In this case, your system should be operating in
Net
metering with backup
and your battery choice should be
None
. This tells the SkyBox that no interaction is
necessary with the battery and that no loads can be powered when there is a utility outage.
If you’ve chosen to use a battery that is not included in the pre-configured list, you’ll need to read
Using My
Own Custom Batteries
on page 18.
Charge Cycle
The SkyBox uses a three-stage charging method.
The
SkyBox Programming Guide
provides a basic
explanation of this process.
What you’ll see on the SkyBox screen for
Charge status
:
o
Charger Off
– No charge cycle triggered
o
Bulk
– Battery has reached re-bulk voltage or
Minimum
SOC
or is currently charging up to absorb voltage
o
Absorb
– Battery has finished the bulk stage and is
charging at the absorb voltage
o
Float
– Battery has reached re-float voltage or is
currently charging at the float voltage
