ACOPOWER 100W Polycrystalline Solar Panel

I purchased this system in May 2022. I’m happy to say the system has operated flawlessly. The solar panels put out as much power as advertised. At one point in the day the system was reading 408W total input. That is quite amazing as usually you don’t get that type of power output for only 4 panels rated for only 100W each. The interface is quite easy to program. Installing the panels like I did was simple. But it took a little planning on my part. If you are planning in installing this system on top of a RV or trailer deep Unistrut works great. Wiring the system is straight forward. I do advise since you are working with solar panels that always have some sort on the output that you take precautions in wiring the system up. For me I placed a 40A fuse in line with the solar panels so that if something went wrong with the controller or battery it would blow the fuse and save your wiring. I also placed a 40-amp fuse coming from the battery to protect the battery and the incoming wiring. The only issue I have had with the system is converting from a deep cycle battery to a phosphate lithium battery (lifePO4). It seems if you have an older controller (like mine) it is incapable of accepting the new battery parameters as charging lithium batteries profile is a lot different than standard deep cycle batteries. I contacted ACOpower and they have informed me there is a fix to this. First you need the MT-50 remote module and from that using the USER manual setting you then can set the setting you need to make the system work with lithium batteries. ACOpower has informed me that they are sending me out one free of charge to remedy this issue. The newer version of controllers has this issue resolved so you don’t have to manually input your battery parameters. Overall, I would recommend this system as it has worked great for me and the customer service got back to me within 24 hours and is willing to help me resolve my battery issues.
