[RE-wrenches] Flickering LED lights on and Outback Dual 7248 VFX system

[Kirpal Khalsa]

Thanks folks for the ideas!  So far I have advised a few things.....I will
report back any successes......

Here is the advice I have shared.
1. Get some different makes and models of LED light bulbs to try out
2. Get some different dimmer switches to try out....
3. Try some lights on non dimmer type switches.
4. Switch the fridge to the other leg of their 120\240 V service.
5. Check battery cables for loose connections.
6. Get a new fridge..(they are hoping to avoid this and it is not the only
load causing the problem)

This is an odd problem.....The battery bank and inverter are more than
adequately sized for the loads....The fridge only draws 7 A when
running....and the problem is not just under start up it is present the
entire time it is running.....The same is true for any other motor type
loads that are running....big or small.....long term the fridge is the most
problematic load because of the regular and unpredictable run times....
As LED's become more wide spread and available and cheaper I am hoping not
to run into this problem more often.....They can be a huge attribute to an
energy efficient off grid home....
Thanks for the advice...keep it coming!!!!
Thank you!
