Using battery power to go off the City's power grid

In fact you have now If I understand well two separated battery inverter system

- One for DAC ,preamp ,Amp with Shunyata Typhon

- The second one for Lumin streamer , switch etc...

Since I have a friend with a Denali , I will do the test with this conditionner .

For the audio system, I have just one battery and one inverter, the Giandel 5000W. The Giandel 5000W has one high current terminal and 4 normal US outlets. The conditioner is connected to the high current terminal and one of the normal outlets powers the HDPlex 300W power supply that feeds DC to the Lumin streamer, switch, etc.

I technically have a second inverter connected to the battery but it powers the HT system and is not part of my audio system. I experimented with the second inverter for the audio system but didn’t find it beneficial, at least not in the way I had things configured. I may experiment more with the second inverter in the future.

I haven't mentioned grounding recently but that is something I do with the system.  Grounding an inverter is different than grounding with a house AC line and different types of inverters may call for different ways to ground.  The Giandel manual says to ground to the car/vehicle or to earth.  The audio system's ground is grounded to  the house AC ground with a Puritan Ground Master.  I use another Ground Master on one of the isolated SPDIF connectors on the Lumin streamer and I also use another Ground Master on the ground pin of the Lumin streamer.  In the near future, I may decide to install a grounding rod outside and connect all these Ground Masters to this rod.  I think this would benefit the system.  I won't know until I try.

Any updates?

Anyone try 48 volt batteries?

Exeltech vs Giandel?

How about Victron?

I'm still off grid but I've taken the inverter out of the hi-fi system.  Everything is powered off DC and there is no AC involved.  I decided to remove the AC because I wanted to see how good the system can sound without AC gremlins like AC ground noise.  Also, getting off AC allowed me to sell most of my pricey AC cables and AC conditioner.  I'm still using quality DC cables and DC power conditioning.

As a consequence of this decision, I'm limited to components that only accept DC. Fortunately, there are great gear out there that run off DC directly. DACs I've tried include the Weiss DAC205 and Ferrum Wandla. Headphone amps include the Ferrum Oor and Geshelli Labs Erish 3.  The Singxer SU 6 acts as the USB to I2S converter.  Streamers include the Lumin U1 Mini or a Mac Mini, both converted to accept 12V DC.  The speaker amp is a high end car audio amp the Mosconi Pro 4/30 that is Class A/AB.  It's a four channel but I bridge the channels to run stereo.  The amp powers Magnepan LRS+ speakers. 

It all sounds pretty good.  It's in the same league as the best AC systems I've put together. But by far it is the best bang for the buck system I've assembled.
