Just installed this inverter as a replacement to my faulty MSW inverter https://www.amazon.com/dp/B079VZN1PN/ref=cm_sw_em_r_mt_dp_VKSR6PN8J7GBDEPPZVC3?_encoding=UTF8&psc=1 $565.03 and 1 hour 15 minutes to install in hidden compartment under the sink. I had the same inverter prior to the update except it was MSW and the built-in AC passthrough switch stopped working. I have been using invertors since they came out and I can tell you $2500 is out of bounds from the norm.
