UrlWelcome to the SunWize PRE Design Tool. This tool is intended to quickly provide you the right solar battery system solution, correctly sized for your project location and supporting loads between 0.1 and 60 Amp-Hours per day at nominal 12V or 24V DC. Loads larger than this should be directed to our Power Ready systems.Please complete the Solar Resources and Project Loads sections and then hit the submit button at the bottom of the page to be re-directed to the appropriate power system on our webstore for your application. The submit button is only visible once valid Solar Resource and Load values have been chosen.Questions? Don't hesitate to call us at (866) 827-6527 or use our Online Chat!Step 1 - Enter Project Site Info Project Location Input Use State/City Lookup!I have my own solar data! Use our State/City lookup for your project site, or input your solar resources directly if you know them! Worst Month Average Sun Hours (kWh/m2/day)Sun Resources: kWh/m2/day Step 2 - Enter Loads Info Load Input I Know My Total LoadsUse The Load Calculator 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! Battery Bank Voltage 12V24V 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 voltageLoads Summary Total Loads at Battery Bank VoltageTotal Loads: Ah/day Total Load in Ah/Day for All Devices Selected Battery Bank VoltageBattery Bank: Volts DC Enter your email address to receive a design summary * For Quickest Response, Please Enter a Phone Number Confirm Site & Load Info I feel confident in my site and load information above I have questions regarding some of the above information Micro-climate scenarios, extreme temperatures, site shading, and many other factors may impact system performance. Please confirm the above site and load information is accurate before proceeding.
