Realize this is an old thread, however in all fairness, wanted to provide update on using the Boliy..... As advertised, the Boliy had no problems starting our 15k aircon unit (I did install one of those Supco Capacitors though to assist) and after many 10's of hours of use, we are still satisfied. However, we have had the opportunity to test out the warranty service, hence reason for this post. At the end of August, the battery went dead in the Boliy (still worked with pull cord) and shortly there after the unit stopped producing AC power. I contacted where we purchased and they referred me to a business that is responsible for warranty claims. This individual was honest right from the start and stated that the inverter module on the 2010 models had some returns and was redesigned. The choice was given to send the unit back for repair or they would send me the new battery and the inverter unit. I choose the latter, taking my time it took less than an hour to repair, (did some cleaning maintenance along the way) the unit is back to normal. First thing I noticed is the redesigned inverter module has 4 smaller capacitors vs the 3 x 1k capacitors on the original. Anyway, while it's unfortunate that the unit had problems, I was pleasantly surprised by the upfront honest way the problem was handled. In after-repair testing, the unit seems to handle the 15k aircon start even better than it did in the past, with much less rpm change of the motor.
In any event, considering I've expressed positively in prior posts, I thought it only fair to relate the problem that we had as well.
