DC power meter for RV


New Member
I purchased a PZEM 051 meter such as this:

It's not bad, but it only seems to show me how much power has been consumed.

I'm wondering if anyone can recommend a power meter that displays power remaining. I only want to spend around $20 - $30 if possible.

Just a quick follow-up. The documentation that comes with that meter isn't all that great which makes the initial setup a little difficult ..... but it works very well once you get it set.

I bought this one last week. It's seems to be of fair quality. I haven't had time to play with it yet.
