Review on 🌞 ALLPOWERS 20A Solar Charger Controller: Intelligent Regulator for 12V/24V Solar Panel Battery with USB Port Display by Justin Reedy

I liked the price but. After installing the device, I found that the battery voltage displayed is wrong. I tested this with two different voltmeters. I asked a question on the provider's website and received an out of office message. Wrong voltage is bad when charging batteries. Second, I set the max charge voltage to 13.7V and now it charges at 14.2V. Not good, can be dangerous and cause a serious overcharge condition. The rest works fine. I will be back unless someone to the best of their ability corrects me if I do something wrong. If so I will update my review. Update** I tried to resolve this issue with the vendor but either there was a language barrier or they just don't care to support their product. I have explained the situation in several email exchanges and the vendor simply does not acknowledge the issue or understand the technical issues I reported to them. In any case, it ends up in the trash can. **WARNING** For those of you with a voltmeter, I strongly recommend that you verify how your charge controller is working and not just plug it in and think everything is fine. The Allpowers device I bought here should go into "Float" mode when the battery voltage reaches 13.7VDC, which is the factory default, BUT it doesn't. It will continue to charge until the battery reaches an unsafe state of charge, at which point the acid in the cells will begin to boil, releasing dangerous gases. You may not even realize this until it's too late and your batteries die (at best) or explode (at worst). Please be careful!
