H should be set when the product is connected to car power, and M or L should be
set when it is connected to a portable battery or other back-up battery. Because of
the dierent output voltages between vehicles, the battery protection level can be set
from H to M or from M to L if there is a voltage protection code F1 shown on the panel.
The battery protection level should be set to H if the product will keep working after
turning o the car engine, or the product may drain the battery.
Solar Charging Management
To make sure your fridge is being charged by a solar panel, please turn the fridge on
first. The battery icon will flash on the display screen to show the charging status. The
fridge can be turned o while it is being charged. Press and hold
button for over 3
seconds to check the battery status and voltage. An extension cable may be required
to keep the fridge in a cool place (to avoid overheating) while the solar panel is in
the sun. Input power for charging should be higher than the refrigerator power draw
(about 40-45w), otherwise the optional battery will not charge at the same time. To
ensure that solar charging power is higher than refrigerator working power, a 100-
Watt solar panel is advised.
