4.2 Charging Information
The SunSaver Duo is an advanced, fully automatic solar battery charger. No
adjustments are required except to select the battery type at installation. Each battery is
charged independently. The SunSaver Duo has a 4-stage charging algorithm as shown
in figure 7.

Figure 7. SunSaver Duo charging algorithm
1. Bulk Charge
– Recharging with 100% of available solar energy.
2. Absorption – PWM constant-voltage regulation to prevent heating and
excessive battery gassing. Pulse charging to restore full battery capacity.
3. Float – After battery is fully charged, SunSaver Duo reduces to a float or “trickle
charge”.
4. Boost (Flooded battery type only – Every 28 days) – A boost charge for flooded
batteries, bringing uneven cell voltages into balance and extending battery life.
Sometimes called an equalization charge.
NOTE:
A 15V maximum battery voltage limit prevents damage to sensitive DC loads.

Protections
Over-current – Solar charge current exceeds the current rating of the
SunSaver Duo. Automatically reconnects in 30 seconds.
CAUTION: A mis-wired connection of a battery to the Solar
input when a second battery is already connected to a
Battery input may damage the SunSaver Duo.
High Temperature
– The heatsink temperature is above safe limits.
Automatically reconnects when heatsink cools to a safe temperature.
Short Circuit
– Solar input power wires are short-circuited. Charging
automatically resumes when the error is cleared.
Battery Reverse Polarity
– Battery 1 or Battery 2 power connections
are connected backwards. Error clears when the mis-wire is corrected.
