i use a Coleman 7.5KVA genset at home, matibay at maingay since open type. i suggest you buy at least a genset with 5KVA capacity because 80% lang ang recommended load nyan..so if 5KVA e a little less than 4KVA lang dapat load ng genset. with my 7.5KVA coleman, i could turn on 2 split type airconditioners, a bunch of lights, a big 2 cabinet refrigerator, a PC and TV to boot.

regarding spare parts, yes mas madali hanapan ang japanese brands like Robin and Honda. but since we're a hardware depot, parts isnt a problem at all
