Im going with Abyss. Excellently built in BMS that will pass 100A continuous and 700A for 5 seconds. Simple to install. Very good support. Phone app will show current draw, status and other data.
A little more than others but premium parts and build.

Simpleton (?) question on Battery Power:
If we are comparing grid power with 2-3% harmonic distortion, with Voltage between 120 -125, what is the advantage of Battery Power with similar distortion (from Inverter). And, if Battery power, like the Grid power, would also benefit from some sort of power conditioner.
It seems direct battery DC power, with no ac/dc inversion, however implemented, would be the ultimate solution?
Relatively simple Diy battery to dc components like network switch/router? And more complex dc battery to dc rails on amplifiers?

The distortion from an inverter is most likely 20,000 hertz. The Fets switching speed to turn DC to AC.. The distortion on electrical power lines is usually 180 herts, 300 herts and 420 herts. The 3rd 5th and 7th of the fundimental 60 hertz. Most filters start filtering a 10,000 hertz, and they're more optimum at 20,000. I have been told some people like a Puritan 156 following the inverter. I have been told a very nice option is a Puritan 156 with 2 x Torus 8 kVA Tots plugged into the Puritan. One for amps, the other for front end.
So yes, a filter can be beneficial.
I am slightly spun again. I want to meet with my distributors lead installer and see some installation. I want to hear what mehanical noise the Victron puts out. A marine tech was telling me they can be noisy little buggers. The larger they get the noisier, they are. The small ones are dead quiet. Maybe that's why stromtank uses a 750 kva unit instead of a 3000.

The Puritain 156 claims to block DC in the mains - DC blockers are known to increase significantly the mains impedance. What do your sources say about it?
Please have your favorite amplifier altered by the manufacturer to run on a battery. I will give you a battery at my cost.
So does an isolation transformer. Who cares. So I had 480 amps peak power available from the wall. After the filter I have 360 amps available. So what?????? With a Torus, on the vast majority of equipment, I hear obvious improvement all the way around. Better sound stage, better dynamics, better bass. Cleaner like it came out of a dishwasher with rinse aid!!!!
I'm just repeating what I'm told. I'm not a Putitan fan or user. I'm not a Shunyata or Isotek or PS Audio or other fan either. I don't like most filters. Wil asked about the THD from a Inverter and I noted where I believe noise might be and pointed out something affordable that could be tried.
That other person using the Puritan and 2 x Torus Tots is actually using the AVR version. The auto voltage regulation. You don't need a battery/inverter with that system as you have a lot of isolation from noise in the utility power and you have true voltage regulation with protection from over and under.
If voltage fluxuation is your main reason for thinking about a battey/Inverter, a AVR Torus will solve the issue on its own. Its the only filter that does
FWIW Equitech has approached the voltage regulation by inserting a large Eaton UPS into the power supply, then outputting to their wall mount unit. Basically the same as I am advocating. I think a quality inverter and Lithium battery will sound better than a Eaton UPS with AGM batteries.

I am only addressing DC blockers. The Torus is not comparable - IMO it is an apples and oranges affair.
Have you something to add on this aspect of the Puritan? I must say it is subject that interests me.
I don't know anything about Puritan accept that a lot of people with up to moderate systems like them. I know a couple people with higher level systems. By that I mean they are very well tuned in a good room. Those people find Puritan to close in the sound some and a small loss of dynamics. Even on the front end.
I think its worth it to try a filter. Many times they help.
Why do I hear people say a transformer does not block DC. I thought DC could not jump from one core to the other. Isn't a transformer similar to a Capacitor in that sense. Why would a Cap block DC but not a transformer?
It don’t block dc offset. The term used is incorrect it’s realty sign wave distortion
it effects the curve and this loads the core
The capacitive correction helps the phase of voltage and current but it has effects on the total power due to the capacitor inline with the line.
if one uses a battery this isolates totally
And only uses the input voltage for battery charging.
not like a ps audio regen does this does help but does not help the effect in the input transformer

As I said, I was not addressing transformers. But as transformers block DC, why having capacitors in series with the mains when using the Torus? It seems a poor option.
Agree. On the surface it seems silly. What I do know is Puritan starts filtering around 10khz. Torus starts around 50khz. If the Inverter noise is around 20khz, then all the Torus would really affect would be harmonics of the fundamental switching frequency.
This was just one persons assessment on multi filters. I have heard maybe 5 people with battery power say they like a filter after the inverter. The person using the Puritan/Torus is a dealer for both Puritan and Torus, so there is that. But there is also peoples perceptions. He says he hears it. Of course, he also heard a whole lot going through a process to clean up his panels and branch wiring. And changing some outlets. He heard a dramatic difference doing just that. I then asked him to reassess his perceptions of the Puritan feeding the TOT AVR Torus units. He needs time to let it settle and do this. His opinion may change if he had oxidation in his power supply that was something the filters were trying to address.
Your saying actual DC in the fundimental AC is different than the affect DC may have on the AC sine wave?
yes , but i cant see how dc can exisit on a signwave . possible as noise . the term dc on the mains is the effect not acual dc.
if the signwave is not .
here is an AI reply but this is not really correct but does yield effects and why the term is used
