Power Online Ready

Welcome to the SunWize Power Online Ready (POR) System Selection Tool. This tool is designed to help you find the right battery backup system for your project or application. Please complete the Temperature, Autonomy, and Project Loads information and then hit the submit button at the bottom of the page to be re-directed to the appropriate battery backup system on our webstore for your application. The submit button is only visible once valid Project and Load values have been chosen.

Step 1 - Enter Project Info
This tool assumes a maximum battery Depth of Discharge (DoD) of 80%, or 0.80, for autonomy calculations.
Enter Temperature in Degrees Celcius (C). Temperature greatly affects the amount of available energy in batteries. Please select the temperature that most closely matches your winter site conditions.
Enter required amount of battery backup time in days. This is the amount of time that the battery backup system will provide power to your load when your primary power source becomes unavailable.
Step 2 - Enter Loads Info
Use our load calculator to convert your loads into Ah/day, or choose to input your total average daily load value (Ah/day) directly if you know them!
Choose your DC battery bank voltage. You may still enter different AC or DC voltages for individual loads.
Guidelines for choosing battery bank voltage:
-if (1) load, use that load voltage for battery bank
-if multiple loads, use largest load voltage
-at least (1) load voltage equal to battery bank voltage

Total Loads: Ah/day

Total Load in Ah/Day for All Devices

Battery Bank: Volts DC

Extreme temperatures, load accuracy, and many other factors may impact system performance. Please confirm the above site and load information is accurate before proceeding.
