Review on ⚡️ DROK 0-90V 100A DC Ammeter Voltmeter: Battery Capacity Amp-Hour Watt-Hour Power Time Multimeter with LCD Display and Hall Sensor by Miro Dadee

I have two of these. Yes, the instructions are a bit difficult, but how good is it to write instructions in another language? The blocks are small and tricky to build, but once you do it you'll love it. I bought my first one a few years ago and it hasn't let me down yet. It was used to control the input/output voltage and current from a cheap Harbor Freight charge controller. I have since bought another one to use with another solar project. I've also used it in conjunction with my large array, although it wasn't necessary it flashed more. The relay trigger built into it has not yet been used. I may use it with an Arduino solar project I'm working on in the future. The input voltage must be calibrated to match your digital voltmeter. I suggest cutting both to the same source at the same time to achieve this.
