eg. Customer wants to connect 3 Fans + 3 Tube Lights + 3 CFL Bulbs + 1 TV
Step 1 : check the total watts of the customer load. Assuming data from the table on the right.
= 3 x 60 + 3 x 40 + 3 x 15 + 1 x 120
= 180 + 120 + 45 + 120
= 465 Watts
Step 2 :So Numreic HPH 1000 VA will be suitable for our purpose.
Now proceed to selecting the battery based on the backup time required.
