Solar Power Sound System

He told me the battery would run 10 or more hours no problem and would not need charging. This would be nice if doing night time shows! He said the battery's are lead acid fork lift battery's with a 2000 cycle life span using 80% DOD and would last even longer using 50% DOD.

And if they're in a trailer, it won't matter that they're heavy. Good match.

BTW you should know about the 'partial state of charge' problem with lead acid batteries.
Evidently Trojan batteries have at least partly licked that, I wonder if that's the brand they're using.

Yeah, I think the trailer will be the easiest having everything contained. I am pretty much leaning toward the MS-225. It should be big enough for even my biggest sound system and a few things around my house.

Here is a little note below I got from Mobil Solar including the battery's:

And thank you for your interest in our line of solar generators. Our products are designed to provide decades of clean, renewable energy from the sun – and all of our products qualify for the 30% tax credit in the United States. We manufacture all of our products at our California plant, and we strive to use 100% USA-made components. Please find pricing below and a data sheet attached.

A quick note about the batteries we use in our MS Series units: Expected life is 12-15 years. They are industrial deep-cycle lead (steel-case type). We use Industrial Battery Engineering (IBE) out of Los Angeles. We are in our 10th year of business and we have yet to have a customer replace a battery. All of these batteries come with automatic watering and degassing systems installed on them, so maintenance is minimal – about 2 minutes, 4 times a year. We have other battery technologies available, but we are strong believer in industrial steel-case lead.

Better ask about how to avoid the "partial state of charge" problem, where lead-acid batteries go bad faster than you'd expect.
I don't know much about it, but I gather the trick is to keep the darn things 100% charged at all times except when you're actively using them, or something like that.

See e.g.

http://blog.aquionenergy.com/blog/bid/157572/When-Batteries-Go-Bad-Lead-Acid-Performance-in-Failure-Scenarios

Also ask how many charge cycles the battery warranty promises, and check to make sure your budget includes replacing the batteries after about that many cycles.

That 12 to 15 lifetime for the batteries suggests the system is not used daily but more of a emergency power backup where the batteries are kept in float charge at close to 100% SOC.

Be careful. This system may sound fantastic but as a practical daily power source I expect those batteries will die much sooner than 12 years if they are cycled more than a couple times a month.

Hey, somebody else did something similar:

They mounted 6 panels on a trailer with what look like lead-acid batteries.
Specs from their pages:
1.6kW
25 kWh
3500 W inverter

Hey Dan, thanks for the info on this setup, yes these are lead acid battery's. I wanted to wait till I got my new Solar power generator from Mobile Solar before updating this thread with what my decision was. But since you opened it up I will update now. I went ahead and ordred the MS-225 mobile solar power generator a little over a month ago that I referenced earlier in this thread and expect it here in the next couple weeks. Mobile Solar is the same company who built this New Custom MS-200 trailer that you show in the link.

I did look at this same solar trailer package but the trailer was just bigger than I wanted and I wanted the 240 v inverter system instead of the 120 v inverter. If you want to check this 120 v system that Trapdoor Social purchased go to the Mobile Solar website, click on products and then click on used and demo units and it will come up. Or go to the website and click on the MS-225 and check out my new system.

My MS-225 will have 6 of the new "bigger" 280 w panels for 1.680 kwh, 7 kW rated, 12 kW surge, 25 kWh battery capacity, 5 X 9 ft trailer. I am looking forward to this next step for my business using a solar power generator to power my sound system! I have Adventure Fest (mixed surface bicycling event) coming up in October and hope to have it in time to use it for the first time. I will keep you all posted on how well it works it I am able to get it in time.

I will have a new sub panel put in my house with receptacles wired in several rooms to be able to power lights, small refrigerator, fish tank, and other small items for emergency and as much regular duty as it will handle off grid. The goal here is to be able to save my back from carrying coal & ashes, breathing in coal dust, and lower the pollution from burning coal. With the money saved from buying coal and saving some on my electric bill I will use electric heat from the grid. Overall I may not save any money but I will save my back and pollution to the atmosphere.

I thought it looked familiar

Thanks for the details. Your story is great, looking forward to seeing it written up in some solar magazine sometime!
