Hi Troy,
I'm assuming this is off grid. Could you please provide details for the system
(inverters, batteries, etc.).
A single, sudden, 20 amp load is not necessarily small relative to the size of
the system. Is the load 120V or 240 V?

You might want to try one of those lights up where the inverter is and
see if it flickers up there when a load at the other
end is turned on...Use walkie-talkies maybe ?
Are you sure it's not just surge regulation voltage response time of the
inverter itself ?

You should rent or borrow a power quality analyzer to look at the phase
angles and harmonic distortion throughout the day. A scope will also help
to allow you to look at the waveform of the inverter produced electricity.
You need to properly identify the cause of the problem before you invest in
an
your problem due to inductance? Not likely. Check for
undiscovered points of resistive loss in your circuit.

We've got a PV system that has long lines from the inverters to the house (1000
ft or so). While the wires are properly sized (2x350MCMs), it inherently has a
lot of inductance due to the line-length. What We are noticing is that dimmable
