This ms excel spreadsheet calculates the following parameters.
Battery bank inverter calculator.
Inverter battery detail.
Think of this as the minimum battery bank size based on your typical usage.
1 no of 200w 230v 0 8 p f computer.
These are colored in yellow.
In this case a 12v 200 ah battery pack could withstand a 10 amp draw and last only 10hrs but the 24v 200 ah battery bank lasts 21hr 41 min.
Here is a quick guide on how to use the calculator.
2 no of 60w 230v 0 8 p f fan.
Additional further load expansion af 20 efficiency of inverter.
I have seen the excel sheet you have prepared for design of solar panel inverter and battery bank and it is awesome.
2 no of 30w 230v 0 8 p f tube light.
Battery banks are typically wired for either 12 volts 24 volts or 48 volts depending on the size of the system.
I want to maintain the 70 c temperature of 50 liters approx water using 500 w dc heater for 24 7.
Size type tripping setting of main mccb.
Calculate size of battery bank and inverter.
Calculate size of inverter for following electrical load calculate size of battery bank and decide connection of battery.
Welcome to the trojan battery renewable energy sizing calculator.
Select the battery bank voltage v the solar battery bank voltage is the system voltage you have selected for.
The more amps you pull out of a battery bank the less ah capacity that battery bank is which is why most batteries have several different ah ratings based off the amp draw the battery is subjected to.
Select rating of each battery in battery bank.
You may want to consider 600 800 amp hours of capacity based on this example depending on your budget and other factors.
Average run cycle is 10 hours.
However when the 2 105 20 hrs batteries in parallel are used and then put on charge after use the batteries typically register 50 charged.
Size of battery bank in amp hr.
The quick guide to using the solar battery bank calculator for defining the number of solar batteries connected in series or parallel.
A properly sized phi battery bank will prevent over discharge over charge and provide the required amount of energy and power to meet your electrical loads and overall project.
Here my application is little different on solar water heater.
For example 1200w drawn at 240v is only 5a whereas at 12v this current increases to 100a.
Using the inverter calculator indicates 14 35 amps dc load and then running the sizing calculator suggests that i need battery capacity of 306 ah 20 hrs.
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 calculator may take a moment to load use this tool to calculate the accurate quantity of phi batteries relative to your loads and balance of system equipment.
Please remember that this calculator works out the minimum battery bank size for a given power consumption.
