electron69 If the two inverters are not made for this purpose, e.g. if no synchronisation exists and clearly advertised by the manufacturer, of course that you can absolutely not do that or you will destroy one or the both of the converters. I cannot understand that donkeys can reply that it's possible without to have first made strong electronic or electric studies. Even in the professional world we never can put in parallel UPS if those are not especially made for. And only 1% of the available professional UPS are with this ability. People that assume clearly that it is not electric engineer should study first before to give such wrong advices. Those loads are not passive resistors, they are active equipment from cheap conception and not able to do the same than professional equipment.

electron69 We can believe that there is an error, should be max 8980 mAh!
