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

sirnui,

I have been worried about you.  Did you get a severe shock from connecting the battery to the Giandel?  Did the sparks cause a fire?

Maybe you are not happy with the Amperetime/Giandel, or else you would have reported enthusiastically by now.

I hope all is well.

All is well and the music flows like fine wine 😁 I've been very busy with life (mostly good) and replying back to this thread has been low priority. 

We're working with essentially a 12V car battery so sparks can and do happen so wear proper eye and glove protection and mitigate the sparks by using a resistor.  My 30 Ohm 25 Watt resistor came in last night and I will use that next time when making connections with battery (inverter and charger). 

I've been listening with the Puritan/Giandel combo and it's as good as expected.  I'm going to use an analogy to help describe what I gained.  I had an old pair of eye glasses and I recently got new ones.  With the old ones, I could still see 20/20 but they were scratched up.  Over the months and years, I got use to these scratches because I could still see very well.  When I tried my new pair of eye glasses, the clarity without the scratches were appreciated.  Comparing old and new, I also saw that the old pair had a yellowish tint that I never noticed before.  After having the new pair, I can't go back to the old pair.  I'm going to be cliche and say a sizeable veil has been lifted with the addition of the Giandel.  I can hear the improvements easily with my headphone listening and with my Kii Three Active speakers.

For anyone already with a good power conditioner, I believe the addition of the Giandel will enhance the performance of that conditioner and one may be surprised at the level of improvement.  I've tried the Ecoflow Delta Pro, Bluetti AC300/B300, and now the Giandel 5000/Amperetime Battery.  The rest of the system has not stayed the same throughout my time with these three solutions but I believe the Giandel is the best performer of the bunch.

For how I plan to charge and discharge the system, the 200Ah Amperetime battery is not big enough.  It's running too low on capacity at the end of the day.  I'm returning it and getting the 300Ah model.  Also, the Amperetime 40A charger is not as powerful as I would like, so I'm getting a Progressive Dynamics 80A charger (the one for lithium batteries).  This new charger requires a 20A outlet which I have.  I currently use a smart plug to automatically charge the battery at night and this has worked out very well.  With the new 80A charger, I now plan to use a smart outlet that can handle 20 amps.

Big Thank You to ricevs and oeno for sharing the Giandel!

Thanks.  How do you apply and then remove the 25 watt resistor when connecting the battery with the Giandel?  Which smart plug do you use for recharging the battery, and how?

Giandel actually recommends 500 Ah of batteries for the 5000.  However, your system is only 220W, the present 200 Ah battery at 12.6V should last about 10 hours for continuous full power music at maximum output.  For most music, the average power requirement would be much less, so you would get probably 40+ hours of continuous music.  If you listen 1-2 hours/day, I would think that the single 200Ah battery should be enough for several weeks without needing a recharge.

How to use resistor: https://youtu.be/ZlrtmJRfSP8

I use a TP Link HS105 Smart Plug to turn on/off power to the charger. I use the Kasa app on my iPhone to schedule the power on/off.  I leave the power switch on the charger to on.

Ease of use is very important to me because it's not just me that uses the system. So part of making it easy, I leave the inverter on 24/7 and this drains the battery quickly. Last night while watching a movie with the family, the charge went down to zero.  So I'm getting a bigger battery and I may also start charging midday for an hour to mitigate losing power during late music listening or movie watching. 

If one doesn't plan to leave the inverter on 24/7, then a 200Ah battery is plenty and the 40A charger would be more than enough. 

One datapoint.

Clean power matters based on use of NBS power cords which prompted even my audio hating x to ask What did you do? 

Things that made no difference either way in The. System. That. Time. Forgot. They did not make things worse. They did not make things better. They simply made no difference to the sound quality in my system.

You know what will improve the sound quality of your system? A 1/2" A80 + 468 = live. I make this bald faced subjective statement of fact having never heard your system. 

You're prolly right.
