The easiest way to size a battery bank with Trojan batteries is to use the Trojan battery sizing calculator:
You will just need to know:
1. Your desired solar system voltage
2. Whether your solar system will be grid-tied or off-grid
3. What your system preferences are (depth of discharge, battery type, and days of autonomy)
Once you have determined these factors, you will need to input the load you will be using. See also our article Battery-based System Load Analysis. With this information put into the battery sizing calculator, the system will recommend a few different battery designs.
