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...

Re: Charge controller for wind off-grid applications

in my setup, the turbines are only designed to charge the battery in absence of any solar power coming in. Mostly used just to offset life cycles.

Re: Charge controller for wind off-grid applications

If you set the unit to just a hair below float voltage using the on board knob the unit will break when the voltage is above that and will run when its below that. I have 3 Primus turbines that will be ran that way. If you look at YouTube Primus who bought out Windstream has tons of how to webinars ...

Re: Clipping panel solar input on a PWM vs MPPT

Here is the reply I got back from EPever, Thanks for your email. For PWM contolller, as long as the total open circuit voltage and short-circuit current of the solar panels after in series and in parallel connection do not exceed the rated value, the controller will not be damaged. Power is secondar...

Clipping panel solar input on a PWM vs MPPT

I know that OutBack Charger controllers will clip at the rated input wattage once its met and for some sizing applicatons this is even the goal. My question is will PWM also do the same or will they go in to a shut down mode? I am not asking about exceeding the input voltage. I have some used panels...

Re: Thoughts on Refurbished Forklift Batts

All this has been good info as I have come to expect from this board. I am hoping to bide my time with the forklift battery to go lithium once the battery dies and the tech comes down in price. I am thinking a new 48 volt batt at 1000ah at 20 hr might be a better route new.

Re: Thoughts on Refurbished Forklift Batts

Makes me wonder if you were able to get a refurb with a guaranteed 85% or better capacity then would that be a better option then a new battery, of a capacity 20% smaller. That would be an increase of 5% for the refurb.

Re: Thoughts on Refurbished Forklift Batts

I think what is turning me off the most about going refurb is that I would have to spend a portion of my array maintaining a part of the battery I can never access.

Thoughts on Refurbished Forklift Batts

Is a refurbished battery that has a guaranteed capacity of 85% or better just a battery that you have to maintain 15% more capacity then you will ever get out of it? I am looking at some units from Green power forklift battery. If I could get one big enough that the 15% loss of capacity and still me...

Making the wrong choice to send my kids to government schools would be easier and cheaper too but it does not answer my question. Did you not read the part about the power company also assuming rights and privileges to your property once you hook up to the grid?.. no thank you.

Re: Not Ideal but need to buy some time.

Kurt please excuse my ignorance but what is the big difference between the "A" version and non "A" version?

Re: over sized

I started off my system with 4500 watts of panels and 10.4KWh of LI batteries. We have a house and guest house and 5 adults, so that wasn't quite good enough in December. So on Jan 3, I added 6 panels and 2 more batteries and now we have 6300 watts and 17 Khw of storage. The generator has only run ...

When it came time to purchase ...

Re: over sized

I was lucky enough to run the small system in my signature line. It ran not quite a third of my yearly needs in my current grid tied system. With very sloppy math I figured I need roughly three times as much. Normally most people who are sizing a system don't have the benefit of having a previous sy...

For an off Grid applications does it make sense to over say your pv array beyond the size of your inverter? I know the inverter will only make what it is rated for but should you not have an array larger then the inverter to cover days with low sun hours? I would assume that this is how it works tha...

Adding a third flexmax to GS8048

In the pre-wired package the system comes with two flexmax 80's. I cant find anything in the installation manual that talks about adding additional flexmax chargers. I would like to believe that the system is integrated and talks to each other and maybe they do this with two but will they do it with...
