Re: Best practices for off grid battery life?

Another question I have, is on the mate 3 screen, on the screen used for setting up the charging parameters. It has a current limit and then a section labeled as "Absorb End Amps" the default for this is "0" . What should this be set to?

Re: Best practices for off grid battery life?

The charge cycles I posted are not located on the website and were a email I received from tech support. Should the FNDC be calibrated to float representing 100%? Or should it be calibrated to the state of the battery after it has met its absorb requirements?

You can see all the model numbers and components by clicking on my profile. The equalization cycle is used for desulfication and is recommended to be done every 5 days.

Re: Best practices for off grid battery life?

It is a GB forklift battery that is sold in banks of 6 2 volt cells for solar applications. So it is wet cell. Yes I do mean the fndc. The charging cycles are figure by adding up the requirements of each bank.

Re: Integration of third charger controller. In to a pre-wired

outback-flexnet-dc-system-monitor-outback-power-manual-819942005.pdf Don't know if you have this doc. It's old, but useful. The "Charged" status shows up when the controller senses other external charging sources are keeping the battery above the controller's set Float voltage. The controller itsel...

Re: Integration of third charger controller. In to a pre-wired

I was able to get them to work in harmony after I adjusted the battery voltage compensation as recommended by the board members, Thanks for that! I did also have to go in to the mate3 and adjust that battery compensation there as well. Now a new problem has arrived. When the sun comes up they all wa...

Re: Integration of third charger controller. In to a pre-wired

I will pull out the meter and check them and also check to make sure the menu's match up, but like I pointed out, this CC took the preset values from the Mate3 so I know for a fact that the displays show the same presets. Do I still need to go through and adjust the battery offsets for all three CC ...

Re: Integration of third charger controller. In to a pre-wired

I figured I would ask this question here as it is relevant to the topic, I was able to get the third charger controller wired in to the load center and hook up a com cable to it, when the Mate3 turns on during the initial energizes phase it shows all three cc and when I program the mate3 it loads al...

Re: Integration of third charger controller. In to a pre-wired

So both charger controllers have their own line as you can see in the pic. There is no rail for the third charger to land, as i am adding it after the pre-wired system is already configured. Now looking at it, it does not look like that big of a deal as the bars only server as a rail for the breake...

Raysun,

I think for a clean install that is what I will do, Thanks again your help has been greatly appreciated and I look forward to calling on you in the future.

Re: Integration of third charger controller. In to a pre-wired

Thanks for the shunt info.. yeah 500 feet of 2/0 is pricey but its what I wanted for the three combiner boxes, for the 6 pedestals.

Raysun,

Thanks for the input, that is what I was thinking for the B -, electronically they are all the same point. Also thanks for the conformation on the reducer box! Have a great day!! \:D/

Re: Integration of third charger controller. In to a pre-wired

I know they can handle more then 3 CC with the hub and all but where do they land? I am sure some one will chime in. Also all of my runs back from my combiner boxes are 2/0 due to distance, I guess I need to put them in a box and reduce them down to 4awg before I try going in to the box as that seem...

Re: Integration of third charger controller. In to a pre-wired

Re: Integration of third charger controller. In to a pre-wired

I think you are right. The positive lugs only show up in the schematics when it shows you how to wire it to the breaker. The only lug it shows on the negative is on the bar.

Re: Integration of third charger controller. In to a pre-wired

you can see where the two fm80 (-) fall here. I don't see how adding a breaker expands this for a third terminal for the additonal fm 80 (-) to expand . https://scontent.foma1-1.fna.fbcdn.net/v/t1.0-9/88973739_3047185535312209_3777608025288736768_n.jpg?_nc_cat=109&_nc_sid=1480c5&_nc_oc=AQk4i9fgNs3qx...

Re: Integration of third charger controller. In to a pre-wired

This is how I did it: You need to replace the installed breaker with one double pole double throw breaker which will expand capacity from 2 to 4 charge controllers, and add 1 or 2 80 amp DC breakers, one for each charge controller you are adding. I have 3 charge controllers installed.Charge Control...

Re: Integration of third charger controller. In to a pre-wired

For example, and mind you I am only looking at the wiring schematic at this time so if it different inside the box then please let me know. It shows two negative common terminals, one for each CC and those two are tied to a DC negative plate. Now when I add the two new breakers will a third terminal...

Integration of third charger controller. In to a pre-wired

I ordered a prewired GS8048 and contacted OutBack about what I would need to add a third FM 80. They gave me the two part numbers to breakers. One of them is to replace one set of existing breakers and the other one is to add a breaker for the new FM80. Now I have not opened the load center up as of...
