Can I run my fridge for 24 hours using two 12v 100 Ah batteries and 370w 24v solar panels?

To determine if you can run your fridge for 24 hours using two 12V 100Ah batteries and a 370W 24V solar panel, we need to consider the energy consumption of the fridge and the energy provided by the batteries and solar panel.

The energy provided by batteries

You have two 12V 100Ah batteries, which can be connected in series to give you a 24V 100Ah battery system.

The total energy available in the batteries can be calculated as follows:

Energy (Watt-hours) = Voltage (V) x Amp-hours (Ah)

Energy = 24V x 100Ah = 2400Wh

The energy provided by solar panels

A 370W 24V solar panel generates 370W of power under optimal conditions. Assuming an average of 5 hours of peak sunlight, the solar panel would generate:

Energy (Watt-hours) = Power (W) x Hours of sunlight

Energy = 370W x 5h = 1850Wh

Energy consumption of the fridge

You need to know the power rating of your fridge to determine its energy consumption. The power rating is usually mentioned in watts (W) on the fridge or in its documentation.

Assuming the fridge has a power rating of X watts and runs for 24 hours:

Energy (Watt-hours) = Power (W) x Hours of operation

Energy = X W x 24h

Check if the available energy is enough to run the fridge

Total energy available = Energy from batteries + Energy from solar panel

Total energy available = 2400Wh + 1850Wh = 4250Wh

If the energy consumption of the fridge (X W x 24h) is less than or equal to 4250Wh, you can run your fridge for 24 hours using the specified batteries and solar panel.

Otherwise, you would need more battery capacity or additional solar panels to meet the energy demand.

Keep in mind that these calculations are simplified and don’t account for factors such as energy losses in the system, battery efficiency, and variations in solar panel output due to weather conditions.
