Power adaptor for Westech-Solar 12/24 V cooling boxes from 230 V AC power
This adaptor can be used to power 12/24 V coolers and cooling boxes with ~230 V AC power off the standard socket.
Thus, if no solar power is available, the cooler can be powered from the grid.
NOT SUITABLE for Westech-Solar 12/24V fridges and freezers!
A battery with at least 50 Ah is necessary to power the fridges and freezers.
For grid connection, the battery should be charged with a small 3 A power supply.
