I recently installed a Phoenix 12v 800W inverter.
It runs off a 200ah Gel Battery that is charged by 2 x 370w Solar Panels.
We usually only use the inverter during day time to power two x 250W fridges.
Since day one off using this setup, it’s been making a SHORT vibrating/grumbling/buzzing noise when one of the fridges kick on, and then it goes away
Is this noise normal?
Will it cause damage to anything in the long run?
Please will you please share your thoughts on this if you have any.
Thanks so much.
