Ben Posted June 8, 2021 Share Posted June 8, 2021 I ordered another another msb Controller It was a little damaged so I decided to test it I hooked it up to a spare 12 volt battery Then I used my CV cc power supply on the solar panel input This way I could limit the current If broken no deafing bang or light speed shrapnel getting me in my eye balls It worked ok so far no big loads yet But I did run across something cool The controller looking for the highest voltage and amperage showed its self on the display of my power It was neat to watch it pull the voltage up and down It would try to pull more amperage voltage would go down Then it would raise the voltage until it would get the highest of both voltage and amperage So I tuck a few pics if you look closely the wattage of both matched also The pics show it going up and down finding the most watts 1 Quote Link to comment Share on other sites More sharing options...
Ben Posted June 8, 2021 Author Share Posted June 8, 2021 The make sky blue controllers are packed really good AT least the ones I have bought are I was gave a few of them by a incredible person Shipping damages is crazy now days I don't blame the employees they are probably over worked and under payed Keep in mind I I only buy from one seller on ebay Sean Buckner is the ebay seller I buy from If you have any issues he is fast to respond and more than fair I thought I might have a issue with the above controller so I texted him before hooking it up Without knowing if it was working or not he offered to replace it This kind of service is not heard of now days That's why I only buy from him Genetry solar has also been over the top good to me when I buy from them I feel when we get good service we should let others know That way the good businesses grow and the bad wither away I will try to find the link or take a pick and post it for the right Ebay seller Quote Link to comment Share on other sites More sharing options...
