Hi
Sorry for my English.
Also you use solar energy but that's very important which your solar power in the best condition is 90w and in the night and cloudy sky ,at morning and evening that light angle or value is not enough.
Therefore you must know that :
1-You can save solar energy to battery and you don't use 90 watt in all day long.
2- For device that use different voltage than your solar , you need use inverter for connect device to solar panel .
3- You must calculate of power consumption of each device and be attend that many of device need further up power for starting such as motors and etc...
