SOL20A12-56D-BT
Operation Guide
1. Connect the battery to the BAT terminal. Make sure the polarities are
correctly connected. Sequentially connect the solar panel to SOL terminal
and connect AC source to AC inlet. (If solar panel or AC source is
installed before the battery, and if the polarities of the battery be reversed,
then the battery will be disconnected.)
2. Make sure the battery is properly connected to the unit. If no battery is
connected, then no voltage at BAT terminal.
3. When a solar panel and AC input are connected to the charger, if the
voltage of solar panel is higher than 15V, then solar panel is always the
main power source of the charger.
4. If only solar panel be used as the power source, then if solar panel
voltage lower than 10.5V, will stop charging. The solar panel cannot be
used stand alone without battery connected.
5. If only AC be used as the power source, then the load outputs will be
powered even without battery connected.
