Solar Battery Bank Calculator

I want to maintain the 70 c temperature of 50 liters approx water using 500 w dc heater for 24 7.

Solar battery bank calculator.

Example 1 for sizing solar system battery bank. Battery 2 is a diehard deep cycle 565 cca for the house the bilge is on this battery and is set to automatic since the boat sits in the water when not in use. The calculator assumes you will need to size your system to get you through average amount of sun light in the least sunniest month of the year for your location. Here my application is little different on solar water heater.

I just want to install a solar panel for each of the. Putting the above values into the above calculator the needed battery bank capacity we get back is 1013 amphrs. By using the very same solar battery calculator you can define as well the number of solar batteries connected in parallel if your solar battery bank is composed of solar batteries of voltage equal to solar panel nominal voltage i e solar power system voltage. The calculator recommends batteries based on your inputs and the results are ranked according to cycle life performance.

This calculator is a tool to help you determine the model and quantity of trojan batteries needed for your renewable energy or backup power system. The off grid solar panel system calculator helps you size the battery bank watts of solar panels and the solar charge controller you need. Please remember that this calculator works out the minimum battery bank size for a given power consumption. Look out for things like.

In this case use the wattage calculator at the top of the solar battery bank calculator above to convert the current and volts to watts. I have seen the excel sheet you have prepared for design of solar panel inverter and battery bank and it is awesome. The way the power is stated on devices isn t standard. Each s 530 battery has a capacity of 530 amphrs and a voltage of 6 v.

My questions is regarding my dual battery bank on my boat. We design our battery banks to pair with our off grid systems. Battery 1 12v is a 1000 cranking amp for starting the engine only. This may not sound good since our example needs a battery bank capacity.

For example 1200w drawn at 240v is only 5a whereas at 12v this current increases to 100a. Because of the better efficiency and deeper discharge depth lithium battery banks tend to be only 50 60 of the size of a comparable lead acid bank. Welcome to the trojan battery renewable energy sizing calculator. When using an inverter the current draw on the battery side can be extremely high so you may need a battery bank that is larger than the minimum.
