I got 10 of this sunwire charge regulators but after the installation to my 40 watts ourdoor charge system.
None of them working and took me a month to try and try.
I still cannot get it to work.
But I order other simple charge unit from Morning star and the system work. I pick this SW-IL6 is because the size.
I follow the installation guildline but the battery never got charge at all. Because my system is only running a low voltage LED night light outdoor. That's why take me 2 weeks later to find out the battery went down to 6.00V and dead. After I install the Morning star unit and it took only 1 day to charge the battery back to 12V.

Please help me

Thanks
