The answer is YES! 

An RV solar generator holds the potential to power your RV, offering a sustainable and eco-friendly energy solution. However, ensuring the total energy needs match the output power and battery capacity of the solar generator is crucial for seamless operation.

The key question: Can you rely solely on an RV solar generator for uninterrupted power supply? The answer is a resounding yes. To achieve this self-sufficiency, you need to determine two critical factors:

  • Total Watts Requirement: Calculate the total Watts of your need by summing up the device ratings found on their labels. For devices without Watt ratings, you can use the formula below to get the wattages: Watts = Voltage(V) x Current(A).

  • Figure Out Total Watt-hours: To calculate how many watt-hours, you can use the formula below: Watt-hours = Watts x hours.

Once you've determined the Watt-hour, simply add them all together to find the total daily Watt-hours needed for your RV power system. This figure is crucial in ensuring that your solar generator can meet your daily energy demands effectively.

After figuring out the 2 things above, you can determine:

1. Inverter Size: To determine the inverter size, it's recommended to aim for around 120% to 150% of the total power(W) for optimal performance. This can be calculated by multiplying the total power(W) by a factor of 1.2 or 1.5.

2. Battery Capacity(Ah): You can find the right-sized battery by dividing the capacity of the RV battery(Wh) by your RV's battery voltage (usually 12V):

Battery capacity(Ah) = 2 x (Capacity Of The RV Battery(Wh) / 12V)

For example, if the capacity of the RV battery is 2400Wh and the battery voltage is 12V, you will need a battery with:

Battery capacity(Ah) = 2 x (2400Wh / 12V)=400Ah.

How Many Solar Panels You Need? You can use the formula below to estimate:

Number of Solar Panels = Daily capacity in Wh/ (Daily Sun Exposure in Hours x Panel Wattage Of The Solar Pane in Watts).

For example, if your total Watt-hours equal 5000Wh, the daily sun exposure is about 5 hours, and your solar panel wattage is 200W, thus

Number of Panels = 5000Wh / (5 hours x 200W) = 5 pieces. Therefore, you'll need 5 pieces of 200W solar panels.

You can consider using our online solar-powered calculator for a more streamlined approach to these calculations. Mastering these fundamentals empowers you to make the most of your RV solar generator, ensuring a seamless and uninterrupted solar-powered adventure.
