Question 1

shows the battery voltage & solar charge but the used by  inverter and remaining hours is blank - how do i get this to read?

Accepted Answer

This charge controller device does not monitor your separate inverter. Only the battery and the solar charge. There are 12 volt load terminals on the charge controller but those should not be connected to an inverter per the manufacturer's requirement. However turning off the inverter and monitoring the battery state of charge will let you know how much charge is left to get to the lowest recommended level of 20%. Full charge depends on the battery type: 12.7 for lead acid, 13.0 for AGM, and 13.6 for LiFePo4. If it shows higher that it is showing the higher solar charge voltage.

You can calculate the load on the battery by multiplying the amps of the 120 volt appliances by 10. Then divide the amp hour of the battery (times the current state of charge that this device shows less 20% ) by the 12 volt amp load to get number or hours remaining. Make sure you turn off your inverter when not using your 120 volt appliances.

Question 2

Are there better instructions than the booklet that offers zero explanation of how the device and or the app works to properly monitor my system?

Accepted Answer

Try Ytube it has some decent videos

Question 3

Battery charging volts is set at 14.4v, but app shows max battery voltage at over 20v. is this normal? lifepo4 battery set to lithium on controller.

Accepted Answer

Check to see if the over 20v is the voltage of the solar panel. It is normal for solar panel voltage to be near 20 v. The controller steps it down to 12 to 14.4 voltage.

Question 4

Can it be mounted outside?

Accepted Answer

I don't see why it wouldn't be okay outdoors. The unit is well sealed. UV exposure is my only  unknown.
