RE: Potentiometer Adjustment of the Regulation Voltage for all AIR Wind Turbines and all Battery Types (including Lithium Ion batteries)
The AIR turbine continually monitors battery voltage (as a bulk charging
source) and compares it to the voltage regulation set point. The voltage
regulation settings are preset at the factory to the values illustrated with-
in the table in this document. These values are adjustable for individual
applications. The AIR factory preset point is generally acceptable for most
sealed and flooded lead acid battery types. Most lithium ion (LI) batteries
are designed to be “drop in” replacements for lead acid batteries. Howev-
er, some LI batteries have a lower recommended charge voltage. Refer to
your battery manual for the recommended bulk charge voltage. Using
the AIR manual or information below, please make the necessary adjust-
ments to the regulation voltage set point per the battery manual utilized.
The AIR turbines will function properly using all battery types if the above
considerations are taken into account. Adjustments to the regulation
voltage set point may be avoided considering the following - the larger
the battery bank and more consistent voltage load, the less likely the
need for any adjustments to the regulation voltage set point.
All LI Batteries have a battery management system and should disconnect
if the charging voltage is too high to protect the battery. If the LI battery is
disconnecting during use, please refer to steps below to adjust the regula-
tion voltage set point. It is also strongly recommended with LI batteries as
well as all battery types that when the turbine is left unattended and in-
curs no load for extended periods of time, the stop switch should be tog-
gled to the STOP/OFF position for safety.
In 2020, Primus Wind Power released an updated Lithium Ion (LI) control
circuit card designed to improve the AIR turbine functionality with LI
battery types. It is strongly recommended when using LI batteries that the
AIR turbine is also upgraded to this new power electronic circuit card. Pri-
mus Wind Power offers the AIR Loyalty program with discounted pricing
specifically for this purpose.
