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.
Some ground rules before we start talking about the custom settings:
o
The voltage range on SkyBox is 42 to 60 Vdc. That’s it. Nothing more, nothing less.
o
If your battery needs to speak with the inverter in order to operate, too bad — SkyBox only talks with compatible
batteries from the list on the website. (See the link on page 10.)
o
All lithium batteries require careful programming to avoid over- or undercharging.
o
OutBack Technical Support cannot assist you with programming values that are not available in the list.
We will point you back to the battery manufacturer, so you might as well just start with them.
Now that the ground rules are out of the way, let’s talk specifics. First is the low battery cutout (LBCO) set
point. This setting should be the voltage equivalent of a completely empty battery. Why? Because the
SkyBox uses the LBCO value to define 0% state-of-charge (SOC).
If LBCO is set too high, the battery will reach LBCO well before it actually reaches 0% SOC. The SkyBox
will assume the capacity has decreased and recalculate the SOC accordingly. Over a few cycles, this can
result in the SkyBox only using a fraction of the energy available to it and cutting off power to the loads
prematurely. A similar result is seen when the
Battery amp-hours per string or the Number of strings
are set incorrectly.
