Maybe I missed it, but it looks like you are building 36 speakers???? Where are all of them going. Curious of the lay out and the game plan with all of them.

I need to do a number of endless things...

But...
Current on-going projects in-order are:

1) 4 Atmos heights
With 72 drivers in them (which are going on my ceiling).
4 Fostex supers, 4 Beyma carbon-fiber neo mids, and 64 Dayton glass-fiber woofers.
Multi-hour task.

2) Finish the front baffle on my SAB-24 .(like a 1 hour task + dry time.)

3) Build a solar equipment extension room to the back exterior of the HT building. Finish testing/installing the solar (which is 99% done/ready.)
Re-wiring the lighting and rack to not be grid-only (That is the easy part).
Multi-week task.

4) Pay someone to install a split-AC/heatpump system (potentially ran off the solar too!). 0 minute task.

5) Adding doors to my rack room for equipment and human entryway, plus trim work.
IR repeater (which I forgot during the initial room build. DOH!). Mutli-hour task.

6) Upgrade my projector to a 4K Laser. 30 minute task.

7) Adding more soundproofing to my main entry doors (triple layer drywall, ~200lbs worth). 30 minute task.

8) Potentially adding sound baffling air ducts ("should" do.) Multi-hour task.

9) Buy a Tesla? Add Tesla Solar roof/wall(s) to main house? Nuclear plant service-upgrade?

10) More subs/amps? or just giving up, throwing in the towel, making-do, and retiring / saving for. LOL!

Me not know

They arrived. Came quintuple packaged, lots of layers!



I'll need to buy more in the future but this gets me operational at least...

Are you getting into car audio now or is this for your solar setup?

It's for the solar that will power my lighting, projector and the low-wattage stuff in my rack.
Maybe my AC/heatpump if I can get away with it... (future).

I was attracted to the overall quality of the batteries.
They last like 80 years supposedly, or at-least ~10x longer than nearly any other Lithium battery accessible to mere mortals, and about 60x longer than lead batteries.

More importantly... they can be used in super-cold and super-hot weather (which we get), without instantly dying or exploding or needing thermal management.

They also produce a very stable voltage range, and you can extract like 90% of the electrons that you dump into it, and you can rapidly charge/discharge them, unlike acid batteries...

They are also near-zero maintenance, every few months they should be individually rebalanced without a load attached (which all batteries need), but other than that, nothing is "required".
No distilled water, no nothing. They just work!

I won't really know first-hand until I start using them... time will tell.

No.
I have a high(ish)-power pure-sinewave 240V split-phase DC to AC inverter, which will be connected to a double-pole double-throw automatic transfer relay (already have it) and then to a dedicated sub-subpanel (need to buy it).
It has two modes: battery-preferred ("green" mode) and grid-preferred (active-standby power).

I'll probably use green mode when I'm home, and standby power when I'm away for long periods to reduce outages. Not sure yet...

Battery cable arrived today. Was only able to source 0awg. (0000awg will have to wait, 0awg is probably fine for my needs anyway, I'm not gonna come close to maxing this inverter out. 6kW RMS 18kW burst @ 240V split-phase. 100lbs)

Was able to FINALLY test the batteries and inverter for the first time.

Haven't connected a load yet to the inverter output but the batteries function properly.
I need to build a battery container, and then test the duration that the batteries can hold the idle waste-power for. That's best-case scenario.

I also need to see how much power the panels produce on a cloudy day and how long it takes to charge the bank to full (I'm guessing 2 hours in full sun-light.)
This battery bank is way undersized, but more all in good-time.
Should be able to run my rack for about ~8 hours of solar on a good day I'd guess... time will tell.

I need a combiner box and still need lightning/surge protection on each line. UGH... it just never ends!

More importantly... i NOW have some BASIC way to generate my own free/unlimited electricity, even if the grid goes dark on the rest of the sheeple.

It's enough juice to be able to power a microwave or a fridge for several hours a day, at least it's something... better than NOTHING!

During my May long vacation I bought a new 2020 hot tub, and started building a new BBQ/lounge deck to go around it...





Long projects-thread is long.

I'm on summer vacation for a few days, so far I was able to test the idle power consumption of my solar inverter with a hall sensor, it is 215watts rms.




I also tested the PQ with my SurgeX and it is in fact pure 60hz sinewave and a true split-phase, the waveform was no dirtier than my local power grid. (Unlike the "Reliable Power" inverter I bought previously off amazon, which isn't any of those things!)



I've programmed the charge controller to all of the voltage parameters for the various charge/discharge functionality, given the battery size / nominal voltage and high/low cut-offs: (The user manual descriptions are HORRIBLE, but I got through it...)


In my case 24-32volts is the useable range, that still leaves a small amount in the battery and over-voltage overhead (I could set it to 24.2-31.5v if I need/want it to be more cautious/safe.)


and programmed the battery protect low-voltage cut off, and tested it and it works:

I need a few more cables and bolts and a 2nd sub-panel, but other than that it's ready-to-rock (install/wall-mount).

I may have missed it in this thread, but why are you building an ungodly number of (Atmos? Surround?) speakers? What's supposed to be your "final" goal?

Basement 5.1.4: Anthem MRX 720, Monoprice 2-channel amp, Paradigm Prestige 85F/55C/15B. PSB Alpha A1/P3 for Atmos HSU STF-2, ATV4K, XBox OneS, Harmony Ultimate, Samsung 65" Q7D.
Living room: Yamaha YSP-6000 with 10" Yamaha sub, ATV3, Harmony Ultimate, 55" Insignia 1080P.

I'm only building 4 Atmos heights (but with 18 drivers in each box.)

So I finally grew balls and plugged the inverter output into my expensive rack.
I bypassed the SurgeX because I think it probably wouldn't except an ungrounded connection.

Everything seems to work great.

After running at 520ish watts for 1.5 hours it finally got hot enough to kick on the fans (the thermal sensors and fans work).

Sort of warm... it appears to be the transformer that gets hot. Fans run for like 30 seconds every 15 minutes at this load after >1.5hours.











The UPS and SurgeX stuff is all 20a sockets in my room, but only draw 300ish watts though.

Just quickly threw the panels outside at ground level and connected 5 in series (not the most optimal nor the final configuration.) Even still, was able to generate about 350-400watts rms from 5 100w panels in full summer afternoon sunlight .

525watt draw for 303watt load. Efficiency is low because of improper sun-angle and also because this inverter is WAY OVERKILL for this small of a load.

The load is: all networking equipment, the entire DSP rig, HTPC + 40inch 4K LED monitor, phone chargers, streaming box, and the 7705 and BD player on ghost power.
I usually only have the 7705/player/projector on during movies, and in that case the 40" monitor is off.

The wiring and charger isn't getting warm at all, everything is room-temp at this power-level.

Won't be able to power the lights, microwave, fridge, popcorn maker or AC/heatpump until I get the 2nd sub-panel and ATS wired up. At which point the efficiency should improve with the increased load.
I'll definitely need a larger battery bank and more panels to increase up-time and load-handling. This inverter could easily run a medium sized cabin. I probably could have just bought the 4kW version instead, which is more efficient at these smaller loads.

Anyhow... interesting initial-results none the less.

Well, after about 4 hours of drawing 500watts rms from the solar (~2kwh according to the hall sensor) the battery was starting to get low so I ended the load-test, and used the rest of the sunlight of the day to recharge the battery.

I plugged in the remote LCD for the inverter and that shows the output voltage, load percentage and DC input voltage.
I guess ~303watts is like <1% output according to itself, so lots of headroom left...



With all 10 panels I should be able to generate 520watts with partial clouds, and hopefully somewhere around 800watts in full sun. With decent weather I should be able to get a half-day's worth of run-time with the setup.

I want to get to a point where I can run it 24/7, so if I upgrade to 20 panels, 2 chargers and double the battery size I'd probably get close to that figure (time will tell...)

I've added passive ferrite beads to all of the non-GFCI lines in my mains-panel

Also on every solar panel

and also on the charge controller


If it does something then great... one can never have too much surge protection (only not enough after it's too late...)
I'll probably also add MOV-based lightning-arrestors on the controller, because why not...

The accumulators just arrived, so now I can connect all 10 panels in parallel-series for the first time.
(Without these, I was voltage-restricted to half of them.)
