To see if this kit is right for your needs, you must know that you will be consuming installation.
To know the total daily consumption should make a list of devices to be connected, power (W) of each of them and the scheduled operating time in hours per day.
For example, if you have 4 points of light 9W for 5 hours a day and a refrigerator Class A + medium-size freezer, your daily consumption for lighting is 4x9x5 = 180 Wh / day. A refrigerator consumes 600wh / day and 800Wh / day. The sum of all these will be the total daily consumption, that is, between 780Wh / day and 980Wh / day need the kit you generate.
