good product price is too high for its function.working fine for me"wh"is not useful
Bel display con misurazione volt Ampere e watt Assorbiti. Per uso interno utilissimo pulsante on off per l'illuminazione
الصناعة ممتازة والسعر مناسب بل رخيص جدا شكرا أيها الصينيون باقي التجربة

To get more accurate readings or if your display is flashing... 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.
me parece muy mal que este modulo necesite una resistencia sunt y no solo lo vendéis sin ella si no que ademas tampoco advierten de que es necesaria, ahora me tengo que esperar 15 mas ---------------------------------------------------------------------------------------------------------------- I think it is very bad that this module needs a sunt resistance and not only sell without it but also do not warn that it is necessary, now I have to wait 15 more
It is the same as you can see on the picture. User's Guide is included with package. Reset can only be used from the menu. You have to use the button next to the screen. You have to push it for 4 second than you have to push it for a while. In the menu you have to change the shunt type if you want to use the 50A shunt unlike the 100A shunt. It comes in a proper packaging. The product is usable.
This is a super power meter shows everything you need for your "solar" power generator! But be careful this one does NOT come with the shunt resistor and you MUST have one to really use this meter. I already had a shunt resistor so it was just what I needed! Another great bang for your buck from bang good!
The measurement of all the parameters as described in the catalog works fine and accurate. The display is also large and easy to read. This is a useful item for enthusiast. I highly recommend this for anyone interested in monitoring the electricity usage of any given appliance. A Shunt needs to be procured separately. the add to the cost, the item is priced high compared to its functionality.
I use one of these to monitor my Emergency 12 Volt Solar Powered Back-Up Power Supply that powers MY HAM Radio set-up. I am an ARES affiliated HAM operator and need Emergency Power for communications during Emergency FEMA operations or Declared Emergencies. This unit allows full monitoring of charge, power used and rate of use. Just what I needed. I built another unit for a friend and this unit is also fitted with one of these high quality monitors.
