Yes, the panels can be left out in the rain. If you still have the controller attached to the panels,
check that it is weather proof, or make sure the panels are angled enough to keep it dry.
That just happens to be the exact same watt meter as
mine. I have just found that it was giving wrong figures. Good idea to double
check with a multi meter now and then.
The watt meter should not be allowed to get wet.
The display is explained in the instructions. Did you get an instruction sheet with it?
Everything with a P after it, means the maximum produced since connected. Example 4.88AP means the highest amps since connected is 4.88.
To re set the watt meter back to zero simply disconnect it at BOTH ends and plug it back in.
Going on the display in your
pic. Left of screen it is currently producing 1.85amps. Since connected it has produced 2.725 amp hours. That is your
solar panel has produced it. The bottom number will rotate between all the measurements. The two figures shown in your
pic on the left are the important ones.
On the right it shows that 13.25 volts is going into the battery. Under that it shows 24.5 watts is going into the battery...1.85 amps at 13.25 volts = 24.5 watts. That is what is going into the battery not what is in the battery! To use the watt meter to
check actual battery voltage, disconnect the source end and leave the load (battery) end plugged in.
From what I have just been through over the past few weeks, I strongly suggest that you use the watt meter as a rough guide only. Use a multi meter to get your true measurements.
