Connect battery to charge controller.
Can you charge 24v battery with 12v solar panel.
Let s say you want to compute for the average charging time of a system with a 12v battery with 50 ah capacity and a 15 watts solar panel.
In this article i will explain how to connect a solar panel to a battery step by step.
If it is 72 cells and voc of around 44v then it is a 24v solar panel and can charge a 24v battery.
I will also share a few tips you need to know along the way.
The first thing you have to do it to compute for the ampere rating of the solar panel by following the equation below.

Solar panels are ideal for use in off grid applications.
These panels are great for charging your 12 or 24 volt batteries.
Generally a 12v solar panel should be paired with a 12v battery and a 24v solar panel should be used with a 24v battery.
So just use the solar to charge the 12v battery instead of charging 24v and then use a boost converter to power the rest.
However since you have 12v loads it makes sense to have a 12v battery bank with the 2 batteries wired in parallel.
This 200 watt 12 volt solar panel produces on average 1000wh of clean energy per day in summer on cloudy days conversion will decrees depend on weather condition.
