HOW TO SIZE YOUR SYSTEM – WE RECOMMEND YOU ALWAYS SPEAK WITH AN ELECTRICIAN, HOWEVER, AN EASY WAY TO GET AN ESTIMATED SIZE IS USE THE CALCULATOR BELOW OR LOOK AT YOUR MONTHLY POWER BILL ON YOUR MOST EXPENSIVE MONTH. FROM THERE, DECIDE HOW MANY DAYS/WEEKS OF BACKUP POWER YOU WANT IN CASE OF EMERGENCIES AND DO THE MATH. CONSUMPTION VARIES GREATLY IF YOU’RE LOOKING TO RUN YOUR ENTIRE HOUSE OR ONLY A FEW EMERGENCY CIRCUITS. PLEASE SPEAK WITH A LOCAL ELECTRICIAN OR INQUIRE WITH US AFTER PURCHASE ASSIST YOU IN LOCATING A QUALIFIED INSTALLER. PLEASE REMEMBER IF YOU HAVE TANKLESS WATER HEATER, WITHOUT SOME FORM OF BACK-UP, YOU WILL LOSE HOT WATER IN THE EVENT OF A POWER OUTAGE.
