System Overview - Heliotrope PV RV-45D Operation Manual

RV-45D Features
1) Pulse Width Modulation "Taper" Charge Strategy
Maintains batteries at the highest state-of-charge with
the least amount of battery water consumption.
2) Selectable State-of-Charge
Set from 13.2 VDC to 14.6VDC in 0.2 volt increments.
3) Selectable "Auto-Equalize", "Auto-Float" or "Fixed"
"Equalize" for Flooded Lead-Acid Batteries,
"Float" for Absorbed Glass Mat (AGM) or Gel batteries,
"Fixed" for single set point PWM charging.
4) Battery Temperature Compensation
Automatically adjusts charge setpoint with respect to
battery temperature to help prevent excess water loss or
plate sulfation build-up.
5) Dual Battery Bank Charging
Charges both the Engine and House battery banks from the
same Solar panels.
