Weak solar charging (low voltage
output) Weak solar input due to shade Move to sunnier area
Weak solar due to dirty panels Clean panels
Incorrect setting Ensure DC to DC is set to correct
battery type
Solar charging not meeting demands Power demands exceeding
designed solar output
Add additional solar panels
Reduce load
NOTES*
Expectations of a 300 watt solar charging system need to be reasonable. Running two fridges without adding
additional solar and following best practice with pre-cooling and packing will greatly reduce battery life and the ability
of the solar panels to keep up with power needs.
Using inverters will very quickly diminish battery capacity.
