Connecting two solar panels in parallel.
For example our 115w sunpower solar blanket has the following ratings.
You can think of a charge controller in the same way that you would think of a hard drive on a computer.
Maximum rated current 5 8a.
There is only a certain amount of data that a hard drive can store so you typically purchase a hard drive that is big enough for your needs.
If both panels are rated at the same maximum voltage then you ll get maximum output.
Large off grid solar and battery backup pv systems often require greater charging than a single controller can provide.
Yes you can have two controllers on a one set of panels array.
Maximum rated voltage 19 8v.
Connect the negatives to the negatives and positives to the positives.
