<br>
I saw a you tube video from what appears to be a pretty well versed installer who mentioned that sol ark knows this is an issue and specifically mentioned that his small air compressor will shut his 12kw inverter down. He didn\u2019t mention if there is a fix coming. <br>
<br>
I guess I\u2019ll wait to buy one until they have that issue sorted out. <br>
