Accurate? depends on the solar intensity on the day when doing the measurements. To be honest, I think the tolerance is +-10%. **Q: what is the max input rating? the specs say 100 watt, but then say 400 watt? i fried mine using 350 watts?** A: I have successfully tested trino 280w and 340w pannels.but it is only aprox **Q: I need another solar panel diag tool for my larger panels. i need to check a larger, 92 cell, 327w, 65v sunpower panels. do you carry a solar multimet** A: Rabah R. Thank you for the enquiry. First of all, please write your enquiry very clearly and in detail. Response to enquiry depends of your feedback. Here, I am assuming that you are in the process of acquiring additional PV Panel to enhance Power to your existing system. Am I right? if so....acquire THE SAME type and model panel, do not mix n match like any other thing in life. your system will not function properly . FYI I'm not a seller of PV cells. My previous WS400A got lost and I bought another one. That's all. Good luck and best wishes. KJ Kumar **Q: What is the difference betwen the standard and upgraded models? there is no other info on the page.** A: The upgraded one has LCD display function. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A good purchase! *by A***N on July 4, 2021* Works well, happy so far.
