   It’s actually a huge bump in specs, as this tester also measures from 20VDC to 120VDC, as well as the small nominal bump in wattage. My older FrogBro 1600W only handles up to 60VDC and I’ve used the heck out of it in the past. I’ve used it for my roof mount panels and also my ground mount panels (all 540W bifacial), but 3 in parallel do have the ability to push a bit above 1600W. This Elejoy allows me to run a test on up to 6 panels, 3 in parallel, 2 series, and I’m very safely below the upper threshold! I’ve tested it with one of my spare panels (currently mid-winter, but still pushing some great power!) and it works just as well as my other unit. It’s priced a little higher than the FrogBro, but is worth the $119.99 price tag! These must all be made by the same manufacturer, same cases, same leads, similar manual. These testers are a must-have for anyone that frequently tests panels, portable or gigantic. Even for a hobbyist, you just can’t go wrong, as it makes troubleshooting and spec checks in seconds, versus hours. Before I got one of these devices I would spend hours calculating how panels performed under load. If this is you, you’re going to wonder why you didn’t pick up a device like this sooner.

   The device basically works, showing voltage of the connected array, and is powered by the array itself, so no batteries. The connectors are locking MC4 and need modification if you don’t want to have to use mc4 tools to disconnect them each time you use it. My particular example is quit wrong on the power production, showing nearly double the nameplate wattage on a few panels i checked. Some it was accurate, so you need to a sanity check against real world. Given how inconsistent it is, it cannot be trusted as a professional tool in my opinion.
