A battery below 9V for 12V battery or 18V for 24V battery may not start the
microcontroller properly. Make sure the battery is charged before installing the system.
As soon as Battery (+) is connected, the Status LED (Fig 5.1) will be steady Orange
and then, the LED will blink Green.
5. Connect the Solar Panel / Array next. It is recommended that the Positive of the PV Panel/
Array be routed through DC Circuit Breaker or DC Disconnect Switch (Rated at ≥ 50 VDC
and current capacity = 1.56 times the Short Circuit Current “Isc” of the Solar Panel/Array).
Remember that the Solar Panel /Array will generate power whenever in sunlight.
Be careful not to short circuit the Solar Panel /Array while connected to the
controller, as this will damage the controller.
6. The Negative system conductor of the battery must be properly grounded as
required by code.
6.3.1 DIP Switch Settings
Five DIP Switches permit the following parameters to be adjusted at the installation site:
*Factory preset condition
NAME DESCRIPTION
DIP SWITCH 1 ON* Selection of Battery Voltage for 12V system
OFF Selection of Battery Voltage for 24V system
DIP SWITCH 2,3,4 Battery charge control mode: Battery charging algorithm (see Table 6.1)
DIP SWITCH 5
ON Selection of Auto Equalization
OFF* Selection of Manual Equalization
Table 6.2. Dip Switch Settings
Standard Battery Charging Programs
EVO-30AB provides 8 standard battery charging algorithms (programs) that are
selected with DIP Switches 2, 3, 4.
Table 6.3 below summarizes the major parameters of the standard charging algorithms.
Note that all the voltages are for 12V systems. For 24V system, multiply the voltages by 2.
• Consult the battery manufacturer / battery specifications & select the
appropriate Algorithm.
• The unit is preset for Battery Type 1 (OFF-OFF-OFF) for a sealed / VRLA battery.
• Check your battery manufacturer’s recommended voltage and set the DIP
switch settings that are the closest to those values.
NOTES: 1. All Voltage values are at battery temperature of 25ºC (77ºF).
2. All the voltages given in the Table are for 12V Battery System.
For 24V Battery Systems multiply the voltage values by 2.
