Battery Bank Inverter Calculator

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.

Battery bank inverter calculator.

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. Please remember that this calculator works out the minimum battery bank size for a given power consumption. The calculator recommends batteries based on your inputs and the results are ranked according to cycle life performance. 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.

The quick guide to using the solar battery bank calculator for defining the number of solar batteries connected in series or parallel. Select rating of each battery in battery bank. Inverter battery detail. 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.

1 no of 200w 230v 0 8 p f computer. I have seen the excel sheet you have prepared for design of solar panel inverter and battery bank and it is awesome. I want to maintain the 70 c temperature of 50 liters approx water using 500 w dc heater for 24 7. Size of battery bank in amp hr.

This ms excel spreadsheet calculates the following parameters. Here is a quick guide on how to use the calculator. Select the battery bank voltage v the solar battery bank voltage is the system voltage you have selected for. 2 no of 60w 230v 0 8 p f fan.

Battery banks are typically wired for either 12 volts 24 volts or 48 volts depending on the size of the system. Size type tripping setting of main mccb. For example 1200w drawn at 240v is only 5a whereas at 12v this current increases to 100a. Select type of connection of batteries in battery bank.

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 my application is little different on solar water heater. 2 no of 30w 230v 0 8 p f tube light. Think of this as the minimum battery bank size based on your typical usage.

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. Additional further load expansion af 20 efficiency of inverter. 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. Calculate size of inverter for following electrical load calculate size of battery bank and decide connection of battery.

Calculate size of battery bank and inverter. 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. Average run cycle is 10 hours.
