Channel for REbus communications. All devices in a
1 system must use the same channel (except REbus
Beacon).
Minimum state of charge (SOC) absolute- this is the
2 percentage of charge the battery will discharge to
while the system is in Island Mode.
Maximum state of charge (SOC) absolute- this is the
100
percentage of charge the battery will charge to.
Minimum state of charge (SOC) reserve- this is the
30 percentage of charge the battery will discharge to
using Self-Supply Mode.
Maximum state of charge (SOC) reserve- when bat-
tery SoC reaches this value, PV power is diverted
from charging the battery to powering local loads sav-
100
ing battery capacity for future charging. When excess
power might otherwise be clipped, this extra capacity
can be used to absorb peak PV.
The battery stack will charge up to this current limit
35 continuously after power has been converted from
REbus.
The battery stack will charge up to this current limit

Length of time the battery will sleep for upon reaching
60 its MinSocAbsl while in island mode. Battery will wake
up every hour for four minutes to power search.
Power search setting is the length of time the battery
240 will wake up from sleeping to search for PV power on
REbus for charging.
Voltage level the battery will drain its modules to upon
initiating the Vset procedure. See
