Summary: After ordering this MT50 controller, I read the fine print on the EPEVER page that it was only compatible with non-ACOPower EPEVER controllers. After reviewing both manuals I thought this would work with my ACOPower MPPT controller, which I can confirm. Remarks: With this remote meter you have access to all kinds of additional information. It is also easier to set some parameters (e.g. date/time) via the software interface of the remote control. Recommendations: If you need a longer cable, any STRAIGHT (straight-through) Ethernet cable with RJ45 ends will do. I tested it with a 25ft CAT5 cable and it worked. Pros: Complete kit (5ft ribbon cable and mounting hardware), compatible with ACOPower Midas MPPT controller. YouTube for videos). Verdict: $30, 5 star rating.
