Re: [RE-wrenches] Recycling of LI vs Pb

Hi JayThere are numerous articles. Here are a fewI havn't researched much more than these articles...But it looks like interesting...Not really sure if they are up to full speed yet https://www.greencarreports.com/news/1122631_tesla-launches-battery-recycling-at-nevada-gigafactory

Re: [RE-wrenches] Module-Level Shutdown for off grid systems

Just a reminder to everyone struggling with this issue that only building-attached circuits energized by PV sources require RSD. So ground mounts generally don’t, or at least would only require a disconnect at the building if sending dc circuits into buildings. Energy Storage is covered under

Re: [RE-wrenches] Module-Level Shutdown for off grid systems

For AC coupled battery based systems it’s a pretty easy solution. Any run of the mill module level RSD compliant grid tied inverter system can work. Obviously, there are major advantages to DC coupling and this is were it gets tricky. Outback has a nice string level RSD option with the ICS, but I

Re: [RE-wrenches] Module-Level Shutdown for off grid systems

The difference in topologies is that when the Tigo devices are used with an inverter driving the control is that it is relying on the Sunspec Alliance standard to be implemented correctly between the inverter manufacturer and Tigo.When using the Tigo devices at the modules and the Togo RSS box

Hello all. Here is some information regarding Module Level Shutdown and OutBack http://www.outbackpower.com/products-mobile/safety-compliance/item/imo-fireraptor Tech info: http://www.outbackpower.com/resources/documents/product-documentation/item/imo-fireraptor-technical-documentation *

Re: [RE-wrenches] Module-Level Shutdown for off grid systems

Thanks Mac. Yeah, Tigo was my first choice but then a search turned up this product, the FireRaptor . Funny name and something I haven't heard a lot

Re: [RE-wrenches] Module-Level Shutdown for off grid systems

Midnite Solar has their SOB system that attaches inline with the modules. It can do both String level and module level shutdown. We've used it off grid with success.  The biggest issue is it is not compatible with most charge controllers, except Magnum's PT 100 for some reason.  We used the PT

Re: [RE-wrenches] Module-Level Shutdown for off grid systems

Hi Loren, We try to stay off the roof for off-grid in Colorado but I'm about to do an 8 panel, 2 string system because of a building code where this cabin is located. I talked with Tigo about it and the parts list is: 8 x's Tigo TS4-A-F for each module 1 x's Tigo RSS The RSS will signal the

[RE-wrenches] Module-Level Shutdown for off grid systems

Wrenches, Are any of you looking ahead at solutions for module level rapid shutdown for off grid? Here in CA it's being implemented next year (at least in my area) and I haven't found any reliable, proven, *cost-effective* products yet. I know Tigo has some sort of inline component but haven't

Re: [RE-wrenches] Recycling of LI vs Pb

When it comes to Recycling Lead it depends on the content of the Lead Battery... To my knowledge, Just to name a few... Rolls Batteries, Trojan, Deka, Crown are generally all 98 to 99% recyclable... In developed countries where there are smelters 99% + of all lead acid batteries are indeed

Re: [RE-wrenches] 24 volt LiFePO4 Battery options

Hi Dave, Howie, Et al, With one brand of Li batteries we sell (EPS), if any part of the BMS system fails, you can turn the battery power on manually and continue to function until the repair is made. All the BMS components are external so it is very serviceable by tech or user. Having a spare

Re: [RE-wrenches] Recycling of LI vs Pb

I fully agree. Styrofoam seems totally unnecessary now, they do amazing things with cardboard and the "structural" paper (that's my own word). On another note, can all lead acid, even these newer advanced lead acid, batteries be recycled? Thanks On Fri, Sep 27, 2019 at 9:44 AM Sindelar Solar

Re: [RE-wrenches] Recycling of LI vs Pb

Agreed that this is important and overlooked. Blue Planet is a case in point. While I'm well satisfied with their product and support, the individual battery packs each come with an absurd amount of styrofoam packaging from Murata, the manufacturer. I was told that Blue Planet was working to

Re: [RE-wrenches] Recycling of LI vs Pb

Hi Mark. Great question! This is an important consideration. Tesla has a recycling facility at their Nevada plant for their batteries. Curious how other LFP manufacturers recommend end of life handling. Speaking of waste, As you all are installing systems of all varieties, what are you

[RE-wrenches] Recycling of LI vs Pb

Folks, Has anyone done a good review of the current state of affairs re: recycling Li batteries? I am a bit in the past with a starry-eyed view of Pb with HUP, in particular, believing that Pb batteries have almost a closed cycle product life, ie, we already have infrastructure to recycle

Re: [RE-wrenches] 24 volt LiFePO4 Battery options

I believe that the Unigi II series of cells also has a nano carbon line. Contact Doug Laningham (dlaning...@mkbattery.com) cced above On Sep 27, 2019, at 8:14 AM, Mac Lewis wrote: > > We've installed quite a few GS Nanocarbon batteries and these are available > in 24V. 5000 cycles to 70% DOD

Re: [RE-wrenches] 24 volt LiFePO4 Battery options

We've installed quite a few GS Nanocarbon batteries and these are available in 24V. 5000 cycles to 70% DOD (we usually shoot for around 50% DOD). http://www.gsbattery.com/renewable/renewable-energy-slr-series/ No problems thus far. Not cheap but very high quality. On Fri, Sep 27, 2019 at 3:42
