power conditioning question gentlemen

      I,m considering a power conditioner /surge unit ,Two sunfire subs,nu vista intergrated(draws some juice) ,transport,dac,tt, phono section (dc-ac i may just plug in wall)  .Dedicated 20amp run directly to room x 2 hospital grade rec. I have been looking into richard grays,furman ref,shunyata etc.I have a unique set up here in nor cal.I am completley off grid!,I run a serious solar and res set up with a genny back up.The power is pretty consistant although during changes in genny start up or at time it does fluctuate a little .I never hear it or have never measured a spiked it drops slightly during those milliseconds.I would like to snag a used one in the 1k range .

Can you measure the voltage and THD of incoming current that you are getting? And the turntable speed.
Power conditioning can be a complicated thing, you might have to experiment a lot. My case was simple - I had fluctuating voltage and dirty current in the apartment. Until very recently I was using inexpensive Furman voltage stabilizer/conditioner. It didn't stabilize well, cleaned up the current a little but not well. Now I have PS Audio Power Plant Premier regenerator and the difference is huge. But your situation is different, and those two subs require an additional thought.
I would probably first try something with the turntable and phono only and then go from there. You could start with PS Audio Dectet conditioner from Music Direct for $400 that can be easily returned.

If the issue is the effect of the generator have you considered a battery solution to store power from the solar array? The Tesla product is an obvious option. Battery based power supplies are a big trend in audio with products such as the Stromtank. Looks like you could get the same type of setup at much less cost given your existing array
May I humbly suggest that using Balanced Power instead of pure "conditioning" might yield some amazing results.
