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.
