Re: Build of grid-tie hybrid Radian with lithium battery ban

Nice project. Tell us more about the Lithium batteries you are using. Are you using a battery management system? What are your charging parameters?

Re: Mate3 Firmware 003.009.000 clock runs amuck

I was having problems with the grid use time on the Mate3. I found it really inconvenient to go back and forth to the garage to set the Mate3 so I thought I would try OPTICSRE. To do that I had to upgrade to 3.9.0. I did find the OPTICSRE and easier way to look at all my settings. My grid use is sti...

Re: New Marine Install / Project

Sogorman, you did a good job of dispelling some of the myths around Lithium Batteries. I have found that many of the people on this forum are very knowledgeable about Lead Acid Batteries, but don't yet have a good understanding of the many types of Lithium batteries. It is forums like these that off...

Re: New Marine Install / Project

Sure, no problem. I am trained in economics and finance so all you are getting is the feedback from a fellow hobbyist and former sailor. The Balqon facility is only a few miles from me and I have visited there a few times so I am also interested in how their battery solution works out. Where are you...

Re: New Marine Install / Project

Okay, I understand your 12v loads better and you are correct in wanting to eliminate the weak link of a DC to DC converter. The DC load would be 350 Amps andd 2/0 cable should work for that short run. Big conductors are always nice to minimize voltage drop, especially with 12v systems. I haven't wor...

Re: New Marine Install / Project

What @larrywa is saying is important. 700Amps would reguire 4/0 AWG copper and lots of loss. Upping the voltage of your pack and inverter would mean your conductors would only have to carry 175 Amps and your inverters would be more efficient. It would be helpful to know the loads that you expect on ...

Re: Battery Cable Routing

I also posted on diyelectriccar.com forum and got a suggestion to run shielded wire to the shunt and I will try that and report back. The question was also asked what the frequency of the EMI and I responded that I thought it was 20kHz based on an earlier post in this thread. Any body know for sure?

Re: Battery Cable Routing

I called Outback Support and they told me to talk to my Battery Management System vendor. I have a call into them. This should be a familiar problem since any vehicle conversion running an AC motor is going to have some EMI from the variable frequency inverters that drive those motors.

Re: Tesla's new solar battery - Anyone see this video?

All I have is the warranty info from the announcement. 10 years is 3650 cycles (365 x 10). There is only marketing info that they expect 15 years. For you and me the 350v operating voltage is a non starter, but it is nice to have someone stir up the pricing of storage. In the long term we should ben...

Re: Tesla's new solar battery - Anyone see this video?

Will be interesting for sure. What we off grid folks need is a direct, drop in battery replacement. Really not interested in having to change out my existing Outback system just to get Li batteries unless the total cost makes sense, which I kinda doubt in my lifetime. I'm giving serious thought to ...

Yes they are similar chemistry...

Re: Battery Cable Routing

I know this is an old thread but the AC ripple is causing the Current Sensor on my Battery Management System to fluctuate. As a result it is always throwing error codes. I have Lithium Ion cells and am using an Orion Battery Management System. I tried some ferrite inductor things that go around the ...

I am doing the same thing with with TOU using a AXS port with a Crestron processor to manage the off grid scheduling and load control. ....... That is a nice system.

Re: Forklift Batteries

Try calling or going on Hyster's webpage to see which 12 volt starting battery they recommend. By the looks of that forklift your boss probably doesn't want to spend money on the kind of batteries used by people on this forum. We use Lithium Ion or Deep Cycle Lead acid batteries. You need a cranking...

New market for battery backed systems.

Last week I attended the Tesla Energy announcement of their Power Wall. A month earlier I had begun installing a GS4048 and initially ran the radian off some Lion batteries I had in a vehicle conversion. I subsequently located some inexpensive used Lion batteries for about $175/kWhr. That is conside...
