PV power scales 0 to high value then restarts from 0 (thought it was bad, appears normal for MPPT).Manual is a poor translation and installation instructions do not say what to do with the included temp sensor. I assume it should be on battery somewhere to monitor if battery is overheating? Very weak on details about settings and what information is on the display.
Just what I was looking for, installed this one last night, waiting for the sun to rise up and stress test it.Til now looking great.Photo: 40A and 80A versionsI Will update if anything happends.NOTE: IT'S HUGE!
Amazing.This is exactly like the same MT50 as the original...at less than half the price. They probably all come off the same assembly line. This one has a bit better display than my much older original MT-50.Fun fact...you can use regular RJ45 cables with these, and you can have the charge controller run 2 MT50's. I put a RJ45 splitter on my charge controller and use two of these for my installation; one right next to the charge controller and one conveniently inside.Second amazing thing: THIS seller. Carrier delivered to another city for some reason. This company OVERNIGHTED me a meter to make the delivery complete. You don't see that very often.
Looks are the same, same dimensions, works the same, wiring is the same..... all are the same in every way to the more expensive main brand version, I have been using mine now for 9 months continuously and still working as it should.
Works great - and this is actually an EPever meter
The ad says "Vevor" but the meter is branded "Epever" and the documentation that comes with it is also Epever. I have installed an Epever MT50 before and this one is identical in every way, at a much better price. Can't go wrong.
