Solar Battery Bank Calculator

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.

Solar battery bank calculator.

The lithium batteries we use are purpose built for off grid solar and utilize a special lithium chemistry called lithium ferro phosphate lifepo4 commonly called lfp. Each s 530 battery has a capacity of 530 amphrs and a voltage of 6 v. A good fit for this is the surrette s 530. For example 1200w drawn at 240v is only 5a whereas at 12v this current increases to 100a.

Putting the above values into the above calculator the needed battery bank capacity we get back is 1013 amphrs. I have seen the excel sheet you have prepared for design of solar panel inverter and battery bank and it is awesome. The calculator recommends batteries based on your inputs and the results are ranked according to cycle life performance. Please remember that this calculator works out the minimum battery bank size for a given power consumption.

Look out for things like. Here my application is little different on solar water heater. This may not sound good since our example needs a battery bank capacity. Example 1 for sizing solar system battery bank.

I just want to install a solar panel for each of the. My questions is regarding my dual battery bank on my boat. A battery bank can be composed of a single battery or multiple interconnected batteries that are wired to work as one large battery at a certain voltage and amp hour capacity. 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.

The way the power is stated on devices isn t standard. 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. Battery 1 12v is a 1000 cranking amp for starting the engine only. We design our battery banks to pair with our off grid systems.

The off grid solar panel system calculator helps you size the battery bank watts of solar panels and the solar charge controller you need. Welcome to the trojan battery renewable energy sizing calculator. I want to maintain the 70 c temperature of 50 liters approx water using 500 w dc heater for 24 7. 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.
