Frequently Asked Questions
What should I turn off first when a long power cut begins?+
Always turn off heavy inductive loads first: refrigerators, desktop PCs, sound systems, and traditional incandescent lights. Keep only BLDC fans, LED bulbs, and the WiFi router running to extend backup by 3x to 4x.
