## Questions & Answers

**Q: What is the accuracy level of WS400A solar panel multi-meter?**
A: very useful when you have lots of solar panels to check and work with. 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.
