AILI DC Digital Meter 200V 30A - Voltmeter Ammeter For Solar, Battery, Wind & HHO Systems

About This Product

If you're working with DC power systems - whether it's solar panels, wind turbines, battery banks, or HHO systems - this AILI digital meter is an incredibly useful tool to have. It combines both voltage and current measurement in one compact unit, so you can monitor both parameters simultaneously without needing separate meters. The blue LCD display is clear and easy to read, showing readings from -199.9 to +199.9 volts and -20 to +20 amps with 0.1V/1A resolution. What's really convenient is that it can be powered by the same 12V DC power you're measuring, so you don't need a separate isolated power supply. The accuracy is solid at +/-1% with a sampling rate of about 2-3 times per second, which gives you real-time monitoring of your system's performance. The micro switch on the panel lets you easily toggle between displaying voltage or current values. Installation is straightforward with the included shunt and wiring diagram - it fits a standard 68x38mm panel cutout, making it easy to integrate into your existing setup. The build quality feels substantial, and it's surprisingly compact at about 70x41x40mm. Whether you're monitoring your solar charge controller output, checking battery bank status, tracking wind generator performance, or any other DC power application, this meter gives you the essential data you need in one convenient package. It's one of those monitoring tools that seems simple but becomes indispensable once you have it installed in your system!
