How To Connect Two Solar Panels To One Controller
You can use an inline mc4 connector fuse.
How to connect two solar panels to one controller. Connecting two solar panels in parallel. Maximum rated voltage 19 8v. As clearly visible in the picture it will be enough to wire the positive pole of one panel to the positive pole of the other one and then wire the negative pole of one panel to the negative pole of the other one. Connect the two solar panels to the charge controller.
The wire from the solar panel will be too short to run to your charge controller. If we have two solar panels with same voltage and power the connection will be very simple. My point is that i m using different batteries for different uses and i want both of them to be charged. Series and parallel connection of two solar panels.
The rule of thumb when connecting solar panels directly to a battery is never connect more than c 10 watts where c is the capacity of your battery. For example our 115w sunpower solar blanket has the following ratings. If both panels are rated at the same maximum voltage then you ll get maximum output. Maximum rated current 5 8a.
What is the problem if we connect the same solar panel to two controllers in parallel which in turn each one is connected to a different battery. The fuse rating is specified in the solar panel datasheet or on the sticker at the back of the panel.
