Connecting Two Solar Panels To One Battery

If we have two solar panels with same voltage and power the connection will be very simple.

Connecting two solar panels to one battery.

Here s something you can do. But solar panels are rated in watts so some simple conversion math is needed. This means the solar panel each day will have to supply 1 percent of the battery s total amperage to maintain full charge. You can connect your panels that you have with a usb cable on the end and then just plug it into a battery pack like this one http amzn to 1qauqvs it already has the charging circuit in it and all the ports you need.

I spoke to the people at wedgetail campers about how the two solar inputs were wired. The combined power of the two panels would exceed the current handling capability. With this set up you can easily take a charged battery pack with when you need it and plug it back in later when it needs charged. We can increase the ampere hour ah capacity of batteries when connected in parallel.

In simple words two parallel connected solar panels or batters each of 12vdc 120w 10a would have. 100ah 100ah 200ah. 10a 10a 20a. The first is on the roof.

Same is the case for batteries i e. Disconnect everything reconnect both regulators to the battery on their own no solar panels connected leave for 15 minutes reconnect solar panels to regulators. In the event you have more than one battery connect them in parallel. The wedgetail camper has two solar inputs via red anderson plugs.

Parallel connection of two identical solar panels. 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. The same voltage of 13 8 from the charge controller can charge all the battery connected in parallel. Connect two large solar panels to one battery.

For example a solar panel must be capable of producing 0 5 amp hours of energy per day to maintain the charge on a 50 amp battery.
