   I’ve had two of them so far. First one had worked fine until it went over 60 amps. It popped like a fuse and stopped working so I purchased a second one. It gives reading that are over 200w more than actual outputs.
   I’ve checked it with 3 other meters. So I can’t trust the readings to be accurate. On watts or amps.
   It’s a paper weight as it is. Can see if panels are At least giving output but that’s about it. Hope they see this and send me a replacement. They did react to my feedback and sent out a replacement. Wish other company’s had this great customer Service. Thanks guys very honourable

   Testing solar panels, or even strings in minutes? This tester just saved me hours of work. If you ascribe to the ‘time is money’ cliché, this tester pays for itself in the first day. I have a dozen portable panels that need testing and those will all be finished by the end of the day. Externally powered, so there’s no stressing about leaving the device for long periods of non-use and forgetting to remove cells. The LCD screen is easy to read. Hook up the MC-4 connectors, or alligator clips, if necessary, hit the Auto MPPT, within seconds you see the results. It seems quite accurate compared to the specs of panels I’ve already tested. One very happy camper, here. Side note, the price was around $90, after a coupon was applied, which seemed like a deal that was as good as I could find for the 1600W version. I’m fairly certain this same model is sold under several different brands, as it looks identical to others on the market.

   Not sure it is more accurate than a multimeter but is close enough to not be overly concerned. If you are doing a huge home solar panel layout I would use a multimeter but if you are checking out single panel readings then this is great. Would be excellent to check out used panels before purchase!!

   Worth every penney! With only 30 days to test, much easier with a tester. First set of panels were duds, but without a dedicated test took me over 3 weeks to get weather and time off to coincide. Easy to use and NO batteries!

   Works as advertised. Nice solid case so don’t have to worry about miss placing the cables or it getting wrecked

   I used to work in the solar industry, when we found a bad PV module(s), we had to set up this elaborate test kit to document the under performing ones. Now retired I started some PV charging. Now I saw this ( yes we know ) inexpensive meter that can analyze individual ( modules = panels ) in seconds. The instructions don’t tell a lot, but you will need a hand-held pyranometer. Maybe they are inexpensive now too, however I already have one. When the pyranometer gives the reading of how many watts per square meter, you can apply that to what the Solar Panel Tester displays. So at 1000 w/m2 you should be seeing the same display data that is posted (name plate rating) that is on the back of the module. At 500 ww/m2 you’d see 1/2 of the Imp, basically 1/2 power. Anything under 200 w/m2 is kinda mute. So, I am ready to buy an Ecoworthy 195 watt module, but first I bought this PV tester! I tried it on an older tech 12v Siemens SR 50 and got accurate data from the meter! Next an Ecosonique 60 watt portable I had for a few months, and it was slightly over ( they say that in their ad ). Today’s temp was 26 F with bright sun with passing clouds. Now that I had confidence in the meter, I tested the newly delivered Eco-195w. By that time the best irradiance the sky would give was about 900 w/m2. And the meter ( see photo ) showed 181 watts. Further, ( 195 w * 0.9 ) = 175.5 watt. This was all I had to see! I installed the module knowing it works. Of course, the next sunny day, I’ll measure it at 1000 w/m2 with moderate temps, to get repetitive data. I have read module reviews where folks said it does not have rated output. Well this is a GOOD way to find out. I will update this post if the meter disappoints in the future.

   We are using it to test solar panel pitch and direction to determine the watts depending on how it is angled. We were so happy and also wanted to get identical timed readings from different panels, that my brother bought two more of them by the time I arrived for our next weekend project.
   This product is worth every penny. <3
