Real world question

I have a question about Charge Controllers and how much they can handle. I am in a position where I have increased my panel output but am unable to run wire for multiple Controllers it is a concrete structure with a embedded chase way. How much amps can a Flex 80 actually handle? I realize that it is rated for 80 amps, but i have to assume there is a design safety factor. I wish to run 12 Canadian Solar 255 panels. Again the wattage is over the rating as well. What in the real world would happen to the Controller if i did this. Last year I ran 9 through a flex 60.  The setup is in Jamaica so local Elect. code is not an issue. Thanks.

Re: Real world question


The Flexmax 80 solar charge controller can handle 12 Canadian 255 solar panels, it will, however depend on your battery bank voltage. A 48 volt battery bank will have no problems with 12 panels, it can handle 5000 watts at maximum (per Outback). From you old set up I am guessing you are running on a 48 volt system currently? If so you should be good with the Flexmax 80. You can give us a call at 1-800-320-9514 to confirm and get a quote from one of our sales reps.

Re: Real world question

Hi Jocelyn, Thanks for the reply. Unfortunetly I am running a 24 volt system using 12 Rolls S 590 batteries and a Outback 24/2500 inverter.
So I guess am I wondering if in reality if the flex 80 can handle the wattage, granted it is over spec, but will it work. To replace the wiring would be a expensive and time consuming affair.. I have 1/0 wiring in a 1 1/2 conduit now. Poor planning on my part, but this is where I am at. I plan to upgrade the inverter, but was staying with 24v. This is kinda my biggest question right now. I will be calling as I have a few items to buy, but I understand you may be hesitent to offer an opinion that is not "textbook".
