Intelligent USB Port Display PWM 50A Solar Charge Controller for 12V/24V Auto Charging Regulation Review

A good quality device for its price. Since the documentation provided by the manufacturer is not sufficient, what is written can be improved. , it took me a few hours to figure out why my 325W 38+VDC panel wasn't powering my system's 24V battery. - The charge limit is specified in a programmable board parameter called "High Voltage Disable (HVD)", which is 30V. - As proof of my mistake, I installed a small panel and it works fine and charges the battery more slowly. - To fix things I have…

So I have this cooler that I built that uses a 12 volt auxiliary fan from a Chevy van. Well, it draws a lot of power, so my mind and I decided to bypass the load side of the device and connect it directly to the battery. Long story short, the fan completely drained the battery one night when I forgot to turn it off (which was expected), but when this unit was plugged back in (when the sun came up) it turned on with 24 volts. instead of 12 and ate my batteries to death. Essentially I have a 12…

The device does not work as advertised and the instructions are cryptic. The regulator didn't regulate the voltage and the batteries got their full power from the solar panels. Volt. This damaged the battery of expensive AGM batteries! The instruction manual is not understandable, like all other controllers that are not written in an understandable translation language! Nothing like the explanation written for the purchase of this controller. --• 40A PWM solar charge controller with automatic…

I installed a 100 watt solar panel on my trailer and bought it to regulate my battery charge. I would like the battery not to be charged and I would also like to know: 1. Battery status. 2. current entering the battery and 3. current leaving the battery. This simple charge controller handles all of these tasks with ease at a very affordable price. It's easy to connect and easy to use. I like USB ports because I have radios, flashlights, and flashlights that use AA batteries, and I have several…

I have a solution for your inverter that's killing your battery! Turn off the ON/OFF switch and replace it with a Bosch electric switch). Great idea! Why don't they tell you at magic school?! I connected pins 85 and 86 of the Bosch electric switch as shown in the picture; ref=pd_ys_c_rfy_rp_m_289_3?_encoding=UTF8&pd_rd_i=B017VDI0GY&pd_rd_r=PVATK1DA6EW0D9JBPT0H&pd_rd_w=3bc28&pd_rd_wg=e7gLp&pf_rd_p=59aba8a5-3996-4c3b-b27f-3b92c87407a9&pf_rd_r=PVATK1DA6EW0D9JBPT0H&psc=1&refRID=QAHXCM97V0SB68RW6VVWt…
