MANUAL
Model: EQ 12/24-50
Solar Converters Inc. - Rev. B
IMPORTANT NOTE: Unit is bi -directional in its operation. Please take a moment to ensure the input and output voltage
required and the direction of the power flow. Misconnection or backwards connection of the unit may provide either half
the voltage or twice the voltage to the load, with potential damage to the load and/or unit.
Warning:
This unit may operate from multiple
hazardous
energy sources. Ensure that all power sources are inactive
before making any connections to this unit. Ensure proper procedures and the appropriate electrical codes are followed.
To be serviced only by qualified personnel.
Warning:
Ensure the battery is disconnected and/or safe operating procedures are followed when making battery
connections. Extreme care must be taken to ensure the battery is not shorted. Make sure all strands are inside their
respective terminals. Qualified personnel only to connect and service this unit.

Section 1
Please determine if a step down, step up or battery equalization function is required.
- If the load voltage is 1/2 the input voltage = step down. Go to Section 2
- If the load voltage is twice the input voltage = step up. Go to Section 3
- If used to equalize battery voltage to account for battery voltage mismatch, used as both step up and step down.
Go to Section 4
NOTE: FUSING REQUIRED ON BOTH HIGH AND LOW WIRES
Section 2: Step Down Transformer
Input Voltage: 10.5 - 32 DC volts
Current: 0 - 25 amps nominal
Output Voltage: 5.5 - 16 DC volts = 1/2 input voltage
Current: 0 - 50 amps continuous
2.1 Common Connection
Using wire of sufficient amperage for the load connection (#12 AWG or better) connect the negative of the battery and the
negative connection of the load to the COM Terminal.
2.2 Load Power Connection
Using a wire of sufficient amperage for the load power (#12 AWG or better) connect the positive of the load to the LOW
Terminal.
2.3 Input Power Connection
Using wire of sufficient amperage for the input connection (#12 AWG or better) connect the positive of the battery to the
High Terminal.
