Want to know how much energy your solar panel is producing, the charging status of the battery or draw from 12V fridges, caravan, camping, 4wd, marine & dual battery systems? With the high-contrast backlit LCD display, this ATEM POWER watt meter provides 8 real-time electrical readings: current, voltage, power, charge, energy, current peak, min voltage & power peak with high resolution 0.01A, 0.01V, 0.1W, 0.001Ah and 0.1Wh, which can be viewed with ease. If you use an auxiliary battery, the meter can be powered to measure the range of 0-9V and achieve more precise measurements, as the measurements do not include the small amount of power to operate the meter. A special feature of the watt meter is that it can be easily installed with Anderson plugs and works automatically. Whether you want to monitor how much power your fridge is consuming or how much power your solar panel is putting back into your battery - this handy little power analyzer can do it all.
