What size of solar can I use to charge battery using the 12v (lead acid) solar power manager i.e I want to know what the maximum watts and current (at 18V) of solar power I can use. Can I also use solar panels with voltage more than 18V?

Thanks!

Hi there are several solar power managers in DFRobot, please check the wiki via SKU first.

There are plenty of “solar calculators” that offer to help you design your solar array, calculate size, output, cost, and savings. Some are quite helpful, and others can be outdated, inaccurate, or downright deceptive.
