Howdy Ray, nice rainbow!
Aileen, Laura, And I miss you two. Very glad your feeling good and half way thru your 14-day quarantine. We are "Brushed-Up" and "Off-Grid" here at Kim's place in central eastern Arizona waiting out the storm.
Can't wait to see you guys again,
We are "Off-Grid" 95% of the time, and never needed/ wanted to use our Microwave. We would not have one except it was a gift from last Christmas. It makes a good bread box!
Ray, that inverter will go down in the hall of fame for its years of service!!
A loose ground, a bad connector, or corrosion at a connection will cause voltage drop.
I use Noalox Anti-Oxidant wire paste on every wire/cable connection I make.
Here is a older video I made you may like.....................
