For those who love to drive long distances, solar car freezer have become one of most important essentials. These equipments are easy to use and truly game changers. However, after plug your new purchased solar cooler into your vehicles and you may find it doesn't work. No worries, this article will provide you with 3 repair advice for solar freezer plug car in 2023.
Before we dive deeper into this topic, we need to know over 60% solar car freezer problems are related to supply of car batteries. Normal family used car battery can generate 12 voltage while the number of truck battery is 24 voltage. Current selling solar car freezers’ adaptable voltage range is 9.6 V to 31.5 V. (Car battery output voltage falling in this range will be good for most car freezer）
Most asked questions about solar car freezers are:
- Why my solar car freezers don’t turn on after I plugged it in cars?
- Why my solar car freezers turned on at first, then automatically shut off shortly?
- What is battery protection model and how to use it?
Why my car freezers don’t turn on after I plugged it in cars?
One common reason cause this problem is your battery lack of functionality which means it cannot provide enough power to start the solar car freezers you purchased.
Normal solar car freezers need 65 Watt to start. A lot of cars batteries are too old or lack of functionality to generate enough power to start solar car freezers.
One simple way to verify if your car battery fall in this category is turning on the engine of the car. The car engine can generate way more electricity than the car battery itself. If your solar car freezers turned on after engine on, it means the car battery cannot power the solar car freezers.
Solution: Replace car battery to a new or more powerful one or purchase solar car freezers with inside battery that can power the solar car freezers after your car turned off.
Why my solar car freezers turned on at first, then automatically shut off shortly?
This issue is usually happened when people plug in their solar car freezers in their vehicles for the first time. After successful switching on solar car freezers, the numbers showed on voltage indicator decreased suddenly. Then solar car freezers started turning off, the screen showed warning of “E1 or F1” which indicates error happened. This is resulted by following two reasons:
a. Battery cannot generate enough power:
Solar car freezers require average 40 W power to maintain stable working. Old batteries has bad load capacity which means it cannot generate and supply stable electricity for solar car freezers. With unstable and low electricity comes into solar car freezers, the system will start its protection program which will lead to automatically shut off.
Solution: Get a more powerful car battery which has more load capacity.
b. Cable transportation loss:
All the solar car freezers are connected car with car charger cable. Thin and long cable will loss more electricity during transportation.
Suggest using voltage tester to check the output port’s voltage. If it shows enough voltage to supply solar car freezers, then the cable transportation loss will be the main reason to cause this issue,
Solution: Replace current cable with a short and thick one that has higher load capacity.
What is battery protection model and how to use it?
Most solar car freezers in the market has battery protection model, which is designed for protecting car batteries. Without this program set up, the solar car freezers will get electricity from car batteries instantly till all the power in car batteries runs out.
The protection model usually has three different levels: High(11.6 V), Medium(10.4 V) and Low (9.6 V). Once the voltage from the input is less than the set value, the program will automatically disconnect solar car freezers from car batteries. It will prevent car batteries running out of electricity.
