Re: Mitsi inverter problems
No knowledge of any problems
90% all inverter problems at new installation are due to power supply problems.
Make sure the Neutral is 100% because any poor neutral connection at the isolator / power distribution board / main incomming board can make a 'floating Neutral'
You can measure this by measure N to Earth. Any voltage wetween N&E can be due to floating N & can make problems for any circuit boards but inverter circuit dont like this sort of power supply problem.
