Question 1

Can you use a toggle switch to reverse the small gauge wires so you can read either draw or charge while under load?

Accepted Answer

FYI in the solution I offered above, it requires you to install the shunt for the charge circuit on the negative cable between your charging devices (all of them) and the negative post on the battery.  The shunt for the load circuit should be on the negative cable between you negative battery post and the negative cable for you load panel.  The load panel should have all your loads, both DC and inverter. The drawing that baylite provides does not show any dc loads.  The common connection point should be the battery terminals.  I hope that is clear.

Question 2

Very  happy, what's the proper way to read the "energy" section of the panel? Is it real time or an average of watts per hr?

Accepted Answer

It is neither of those. The Energy section measures how much power you have used over time, i.e., the cumulative total of watt-hours. A watt-hour is equal to one watt of power used over the course of one hour. If you have a 5-watt LED bulb and you power it for 3 hours, your Power reading would consistently read 5 W for the whole time you're powering the bulb ("real time," like a speedometer), and the Energy reading would gradually change from 0 to 15 Wh over that 3-hour period (cumulative total, like an odometer).

Question 3

does this meter count up the amp hrs used and then start subtracting them when charging begins. Giving you a running total

Accepted Answer

I bought two meters, so one measures charge, the other discharge.  (Just wire the sensor wires in reverse for the discharge)

Question 4

I am getting the entire display blinking when i put any load on the system.  it blinks all zeros.   i have it set for 100a, but am less than 100A

Accepted Answer

If your display is flashing or the reading seems out... (also if the reading stays 0 you probably have the wires from the shunt the wrong way round)The problem is the length of wires from where the shunt is (if it is not right next to the battery) causes a voltage drop across the cable that influences the reading and in most causes will cause the meter to flash as I suspect this is the over-read indication. (I am using three meters to measure two banks of solar panels and a wind generator)Solution: tie the battery side of the shunt wire to both 0v points on the meter . i.e. bridge the two inner pins of the connector and take the wire only to the shunt, this then takes the voltage drop over the cable to the battery out of the equation.
