How do you reset the usage? I don't need to reset the cost Kw/h, just the running totals.

Hello, this usage will be reset all, and then you could set the cost again, if you have any problem when reset, please tell us the details, you could send the email to 2968379892@qq.com, we will be surely responsible to this problem. thanks

Where can I download the user manual? The link on your product page is not working.

Mine came with a user manual such as it was. Take a few minutes and look on YouTube;it will be explanatory quickly! Good luck!

Will this meter read the wattage im putting back into the grid?

Yes it does for sure. That is my primary use here

When it is in KWh mode, and it says 4 days at the bottom, do you add 4 days plus the hours at the top? Or do you add 3 days plus the hours at the top?

When I calculate my KWh load I use the day number listed (4) plus hours
