@jlankford Thank you. Does the 12000XP and/or 12kPV operate on similar logic? I'm not willing to tolerate 50 dB of noise all day long from PV inpu...

What about auditory behavior of 12kVP vs 12000XP?

(that last comment should read "800W" not 800 kW!) My worst case steady state load is about 700W, for which silence would be a huge plus. The stri...

@jared To clarify on "Left and Middle Fans: Activate when charging or discharging power exceeds 300W", does that mean PV power input also? In other w...

@jared WOW, that's fantastic information, just what I needed. I have eight (8) X 540W solar panels in a string, so production much of the day is lik...

@jlankford Ouch. Good point about not making assumptions about different units. Thanks, I will look into the 18K / 6K thing.

BTW, I picked up eight (8) California Solar 540W bifacial panels today for just $175 each. That's 4 kW of panels for $1400. That should do a very ...

Thank you very much! Fantastic to have little or no sound. Maybe when it gets to be hot days it will ramp up some, but it sounds like it is as good...

@caesarv Thank you that would be very nice of you. Make sure AC from utility is cut off when testing. Thanks!

BTW, as FYI for "why bother": My electric is minimum $0.48 kWh here in SF Bay Area ("Tier 2" pricing), and rises to $0.55 or higher some times of ye...

Which brings me back to EG4® 3000EHV-48 BATTERY TO INVERTER EFFICIENCY: 94% <=== excellent, as good as the big unitsIDLE POWER CONSUMPTION: <...

Another downside I see to such a large unit is that at low loads, the efficiency is extremely poor. That is, for my steady-state 250-500W load (160W o...

Are you sure it is running off batteries and not off pass-thru AC power?To produce 6000W AC at 94% efficiency (see spec sheet), it would need to dissi...

Thank you, that's actually very helpful. To meet the goal of silence, paying more for a really capable inverter, even if I won't ever drive more then...

Model EG4® 3000EHV-48 ALL-IN-ONE OFF-GRID INVERTER If there is no sound, then you are saying the fans do not even run up to 6 kW load? That is rema...
