PERATION
The ProStar is a fully automatic PV system controller that
includes many electronic functions to protect both the con-
troller and the PV system. Battery charging is managed by a
constant-voltage, PWM algorithm that has been optimized
for PV systems.
The only manual tasks performed by the operator are:
a. Installation (see section 4.0)
b. Battery type selection (see section 4.2-7)
c. Disconnect button (with LCD meter, see section 3.2)
d. Reset if load short-circuits (see section 4.2-6)
e. Maintenance (see sections 5.3 and 5.4)

UNCTIONS
The PV system operator should become familiar with
the following functions of the ProStar controller. Refer to
Technical Specifications (6.0) for actual setpoints and other
parameter values.
LVD - Low Voltage
Automatic load disconnect to protect battery
Load Disconnect
from deep discharge. Auto reconnect.
Current compensated for high load currents.
Low Voltage Alarm
Red LED flashes at low battery capacity to
warn of possible LVD if discharging continues.
Over Voltage
If battery voltage rises above the constant
Protection
voltage regulation setpoint, the PV array is
disconnected. Auto reconnect.
HVD - High Voltage
Both PV array and load are disconnected
Disconnect
when battery rises to dangerous voltage.
The LED’s flash in sequence. Auto reconnect
as voltage falls.
