solar insulation case is combined with solar panel and high efficiency lithium battery and output directly. it will keep the temperature between 10-15degree by the operation of cooling machine which is powered by the built-in battery of solar system, that can keep the items inside fresh and also extend the time of keeping fresh. solar insulationcase is a necessary for household, business trip and also car holders.
一, parametres:
1, total power for solar system and lithium batteru:30w 
2, power for cooling machine:60w
3, capacity for cooling: 0.01p
4, cooling temperature: 10-15 degree celsius ( related to the temperature of environment)
5, built-in lithium battery: 12v 5000mah ( with protection function for over charging, over discharging and short circuit)
二, usage（for car, household and solar）
1, charged by car battery: connect the two dc sides of “e” to cooling machine and solar battery, then plug the car charger to carcigar lighter, and then turn on the switch of cooling machine. then the car battery will charge lithium battery while it is also offering power for cooling machine.
2, charged by solar: connect the two dc sides of “e” to cooling machine and solar battery port, then turn on the switch of cooling machine.
3, charged by household adapter: connect the two dc sides of “e” to cooling machine and solar battery, then plug the car chargerto “d”, and turn on switch of cooling machine
三, working time of solar battery after full charged :
1, if charged by car battery, it will be full charged after 3-4 hours, and then keep cooling machine working for 2-3 hours. it cancharge cooling machine while charging solar battery at the same time. after power off the temperature will be kept for 5-6 hours ( this time is related the environment temperature. )
2, if charged by solar energy it will be full charged in about 8-10 hours in sunshine. and then keep cooling machine working for2-3 hours. it can charge cooling machine while charging solar battery at the same time. after power off the temperature will be kept for 5-6 hours ( this time is related the environment temperature.)
3, if charged by household adapter, it will be full charged in about 8-9 hours. and then keep cooling machine working for 2-3hours. it can charge cooling machine while charging solar battery at the same time. after power off the temperature will be kept for 5-6 hours ( this time is related the environment temperature.)
四, abnormal conditions:
1, if the cooling machine doesnot work after to the power, pls check whether connecting line is loose or whether cooling machineswitch is turned on.
2, if cooling machine stops working after working for a period, it means the power is not enough. then turn off the coolingmachine switch, and put in under sunshine for 1-2 hours.
