36v Solar panel with a 12/24v charge controler

36v Solar panel with a 12/24v charge controler

Hi

I need some advice here please.

I just bought a 200ah Latium 12v battery and 2 x 130w solar panels with a 12/24v charge controller. HOWEVER, now I see that the 2 panels are 36 volts. I am about 800 kilometers from where I bought the stuff so it is difficult to go back and exchange...

My question is: Will my 12/24 volt charge controller handle the 2x36volt panels?

Thanks in advance
The 12v/24v refers to battery voltage, so it will work with either a 12v system or 24v system.

The panel input voltage limit is a different spec, does your manual list a voc figure anywhere? I tried looking online and couldn't find an English version of the manual, but it looks like 50v is the input limit. If so, you would need to connect your panels in parallel to stay under the voltage limit. No Problem.
The Solar Charge Controller (SCC) will take a maximum voltage & amperage in from the solar panels. It does not care about the solar panels as such but only the Maximum Volts & Amps they output collectively. This should be clearly shown in the docs for the SCC.
Each Solar Panel will have a label indicating how many Volts & Amps it can output.

Much like batteries, Solar Panels in Series will increase the Voltage, while in Parallel will increase in Amperage
In Series, you'd get 72V max but the Amp rating on the label.
In Parallel, you'd double the AMP rating while only getting 36V.

BTW: 260W of Panel won't be able to charge a 12V/200AH battery very well. A 200AH battery can take up to 100A charging but would be better between 50-75A Charge input from the SCC (less stress on the pack) * Unless Manufacturer Lable shows a lower limit.

You should indicate the following next time.
Make / Model of Solar Charge Controller (Link to it also so we can see the specs).
Make / Model & Specifications of the Solar Panels from the label on the back. Also a link would be good. The fact that a USB is present suggests that it is a lower budget PWM controller. A PWM will NOT transform raw solar voltage down to your battery voltage, so it might end up being a poor choice.

Basically what will happen is that the battery as a load will drag the panel voltage down to battery voltage, so proportionally, you lose as many watts as you loose volts. The best you can do is just wire the two panels in parallel, as CWG suggests. Assume you are likely to get about 55-60W max out of the panels with a PMW.

Those numbers can be more accurately determined once you post links to the equipment as Steve requests.
