SimpliPhi has given me zero problems over about a dozen systems. so far I
have only used the 3.8kWh units that are not capable of closed loop
communication.

Re: [RE-wrenches] Lithium battery recommendation

[Carl Hansen via RE-wrenches]

 Peter,

  I've also installed a few EG4 rack battery systems, they are working 
out well, tech support is easy to reach, not problems so far, customers 
like the price point. Standard 10 year warranty, company seems pretty 
solid, easy to communicate with.

   You may want to look at the EG4's. Have been using them for several years 
and they have been great. They just brought out a comms hub that could help 
you. Their racks are great as well. $$ is good, especially compared to Fortress 
and the other.

   Take a look

Subject: [RE-wrenches] Lithium battery recommendation

Hi all

I’m
Looking for recommendations for a lithium battery. 48v.  150-200 kWh.
System is probably going to be open comm, as the system has outback equipment. 
That could change but probably not.
Remote monitoring is required even though it is a site with people 24/7.

So far fortress and home grid. Have been recommended to look at.
Blue planet is just too expensive.

And PS. Fortress says that you cannot add batteries after 1 year. This goes 
against everything I thought I understood about lithium.
Any comments about why they say that?
Do others say rhat?

Thanks in advance

Jay

Fortress can be disassembled and moved easily, blue planet comes in
seperate parts and can be purchased in 8, 12 or 16 kWhrs and both have a
cabinet and BMS Included

Keep in mind the Fortress eVault is a 500 lb beast. Our installers
complained about it and we've moved to smaller, rack-mount units and are
currently testing the HomeGrid Stack'd in various configurations.

don't have time in the field to support what they say. I ran a lab testing

Re: [RE-wrenches] Lithium battery recommendation

[Daryl DeJoy via RE-wrenches]

I believe(but am not sure) that it was about their inverters and SolArks
being made by the same manufacturer.
Their batteries had nothing to do with it and while we have had multiple
problems with Fortress and other high priced LiFePo batteries with the same
warranties and expected life cycles , Atlas continues to provide a very
reliable product with very good customer support, when needed. Trying to
get tech support from other manufacturers, especially when the installer is
on site, can be exhausting and futile. Not so with the few times we've
needed support from Atlas.

Just my experience,
Daryl

Re: [RE-wrenches] Lithium battery recommendation

[Daryl DeJoy via RE-wrenches]

Hi Jay,
   We've installed about 400k's worth of Atlas LiFePo4 "Powerwalls" and
"powertowers" over the past two years, many on Outback systems.
  They're located in Utah and the owner picks up the phone most of the time
when I call. They're growing and determined to do it right as they do from
what I've seen so far.

Guarantee you EG4 won't be around in 5 years. Their retailers like
Signature and Sovereign Solar are a joke. Bet you they won't be around long
either. I think you will find more bad experiences than good.

If they are going to spend that kind of money, ditch OB. I've never had an
Outback system, going all the way back, that didn't puke prematurely and
have issues. Discover AES and Schneider for the win. Once they are set up,
they just work.

Re: [RE-wrenches] Lithium battery recommendation

[Peter Giroux via RE-wrenches]

Jay

  You may want to look at the EG4's. Have been using them for several years and 
they have been great. They just brought out a comms hub that could help you. 
Their racks are great as well. $$ is good, especially compared to Fortress and 
the other.

  Take a look

Thx

Re: [RE-wrenches] Inverter On/Off Switch use Outback FX

[Starlight via RE-wrenches]

They did not anticipate the use with Lithium battery chemistry which is mostly 
discharged at 12.7V, and that happens to be the fully charged resting voltage 
of lead batteries. 

Seems as though by now manufacturers should have increased the LBCO voltage 
range in the software.

I'd like to use a 12V Aux relay logic to trip the primary inverter 
on/off contacts before we go into battery shutdown so the solar has a 
chance to recover the system.  Pretty simple overall but I wanted to 
see if there are any known ill effects of doing this with substantial

Thanks for your input!
