Okay team, reading this forum for a few months but never joined or posted. Now I have a question I have been unable to answer through searching the web or this forum.
Setup:
I was able to acquire these cheep, in great shape, and operating "as new"...they are rated at 30W. I am looking for a MPPT Charge controller, and one that is not expensive. Thus after much searching the
Looks as though it will fit my needs, and be inexpensive. My concern is the Max 75V input rating. Does this mean that > 75V will cause damage, or that > 75V will simply be unused? As these only produce > 75V in maximum sun the peroid of time in which they will do so will be < 12% of total sun Collection time. Also is there a better, option for my setup in terms of MPPT Charge controllers that will not break my pocket book ($200-250 max)?
Non Pertinent information:
The battery setup is a series of (used) industrial batteries in series to provide 12V 800AH bank. Real load will be 20 hrs/week of LED light strips that light my basement/garage; These are separated in 2 arrays of 90w each (high efficiency 5050 LED variable wavelength) that pull a maximum of 90W and a minimum of 30W. Right now these are powered by the AC power of my local POCO. As in the heat, snow, wind...or any adverse condition we tend not to have lights. Once this solar system is UP I will be adding a manual switch to go from one power source to the other, and some sensing electronics to cut over to battery, and turn the lighting on in the case of power loss.
Thanks mates!
Setup:
- 6 Solar panels (Thin-film, flex) operating at a maximum of 85v , .36 amps (35w) in maximum sun. Arrayed as 2 sets of 3, in Parallel.
