Battery Power

[Kingrex]

What I would do: Find the components for the best battery/inverter and battery management system you can. Wire and connect to the highest standards you can. Test the set up in a variety of systems. When it outperforms the Stromtank, assemble it all it all in a nice looking and solid box that will appeal to audiophiles. Price it at 50% of the equivalent Stromtank.

Your electrician friend can easily wire it together. It would take maybe 2 hours to buy the parts and assemble it. You don't need to fester over stripping off tin. You already have the RM20.

For me the best battery today this one.

With sine wave inverters from ambulances, they only have a 0.05% deviation in the grid frequency. It's a 12-volt system with three battery packs (over 900Ah) and two 3-kVA sine wave inverters. You'll hear for over 8 hours if the continuous current draw remains below 15 amps at 230 volts. Don't forget to install fuses between the battery and the sine wave inverter. Forklift fuses go up to 600A. Price with housing and charging device: approximately €6,000.

P.S
In case of a fault (short circuit) a special fire blanket that protects your house until the fire brigade arrives.

Do you have a link for the sine wave inverters you're speaking of? Thanks

Votronic in germany in ambulance, for the bigger 3kva you write direct to company. 6 years ago cost the 3kva version 1.4k€

Exeltech would be very similar to Votronic

It's great to see Yeti Acoustics getting some love. We've been fans for years and think they make the best power conditioners on the planet.

I sort of forgot how complex it can be to properly ground a battery/inverter. I was reading about it this morning. The battery, inverter output and metal chassis equipment all need a good earth ground. And once you earth ground, a SPD should be utilized to protect from lightning striking earth near your ground.

Has anyone looked into Ecoflow battery/inverter?

EcoFlow DELTA Pro Ultra | Whole-Home Backup Power | EcoFlow DELTA Pro Ultra (1 × Inverter + 1 × Battery)

Never fear blackouts w/the ultimate home backup solution. Up to 1 month of power & 21.6kW of AC output. Run your whole home off-grid w/solar. Zero downtime

EcoFlow is not as easy as they make it look to install. You still need to meet all the NEC requirements on emergency shutdown, phenalic labels at the utility meter etc. Its like adding a generator.

I've been comparing the P20 to my Torus rm20. I prefer the sound of the Torus. More density and instruments sound more real.

I now am running the P20 in front of the Torus. This may be best, but I'll have to go back to hear Torus alone to be sure.

I occurs to me a regenerator and battery are similar in what they offer and their tradeoffs. The battery inverter will inject it's particular noise and the regenerator it's (high frequency?) noise. The regenerator is certainly more straight forward an install.

The P20 is showing only 475 watts of power usage, so I imagine the smaller P12 would be good for this purpose.

Balanced Power BMU-2500 | Factor One

The best way to extract the full potential Audio and Visual quality from any Hifi or Home Theatre system is to balance the mains. A Balanced Mains Unit (BMU) doesn’t provide the voltages to the equipment in a conventional manner. In an ordinary power supply, extension or direct wall connection...

I stumbled onto this exceptional small business in a review & so glad I did. After some insightful back & forth emails, I decided to have Dan build a custom 2500 watt,10 outlet, highly upgraded balanced mains unit. It is called BMU 2510se & it’s not even on the Factor One website yet. His passion for his work is contagious, as he kept me apprised of the build by sending me photos from his bench. Very nice touch Dan! The very first 2510se serial #0001 arrived in the States well-packed in tip top condition 2 weeks ago. As it settles in, I’m struck by the quiet confidence that it can handle anything you throw at it without breaking a sweat! Center image, which drifted a bit with the addition of the fabulous Heartsound Holostages, is once again well anchored. Soundstage is significantly deeper with layering & location of performers more defined. Highly revealing. Bass is huge! Had to back off the REL. After only a couple of weeks, it’s clear to me that the Balanced Power Factor One BMU 2510se is a thoughtful, capable, beautifully crafted & essential addition to my kit. Check ‘em out! More later…
