Auto-ranging Mode: After turned on, the Electrical Voltmeter enters the autoranging mode, meaning that it can detect and identify the voltage, resistance or current, and automatically select the corresponding range to display it on the LCD screen, no other operations needed.
USB Rechargeable: Each of our Voltage Testers with CE, FCC certification, is built in 5000mA large-capacity lithium battery. Unlike other multimeters whose battery needs to be replaced regularly. Ours can be charged by the ordinary micro data cable (included) for reuse. What's more, this multimeter can serve as a power bank to charge your phone, a necessary and compact measuring tool for your cars and home. A great addition to all your electrical and electronic tools.
Wide Applications: This handheld Digital Multimeter features 6000 counts auto-ranging for high precision measurement of AC/DC voltage, current, resistance, frequency, capacitance, diode, continuity, temperature and live wire and zero wire identification, etc. It is also equipped with multiple functions such as low battery warning, data hold, LED light, 30s backlight, and auto-off after 15 minutes.
Easy to Use: One-handed operation, convenient for you to use this professional ammeter by pressing the buttons. One pair of....

...th MC4 connector to avoid reversing the positive and negative terminals. (Some customers extend the solar panel cable so that the positive and negative polarity is reversed).
Grid Tie Inverter can monitor in real time the power generated by the inverter through the AC digital meter.（Voltage, current, active power, electrical energy, frequency, power factor）No fire risk and electric shock during installation and operation due to low DC voltage(up to 50V) compared with at least 200V from string inverters.
Grid Tie Solar Inverter suitable for 4X250W-300W 36V solar panel (Vmp30-39V.
Voc = open circuit voltage.Optimized for high powered 60-cell and 72-cell* modules.Each MC4 branch cannot exceed 300W.
Islanding protection.Almost no maintenance work is required, clean the dust on the photovoltaic panel occasionally..

The jumper clip is made of pure copper with good conductivity, with an insulated handle, which is easy to use..
This is ideal for applications running on battery chargers (solar panels, electric fences, etc.) or car batteries (camping, boats, electric fences,....
Powerful alligator clip connectors are widely used in various electrical engineering, electric welding machines, voltage testers, and are suitable for....
Pack of 2 fits 100-500A Powerful car battery charger clip connector (1 red + 1 black).

Remotely monitor and control (open and close) your garage door using any Insteon controller (sold separately).
Includes sensors that provide status on whether the garage door is open or closed.
Compatible with traditional 2-wire garage openers only - if your garage control button features a display panel, this kit is not compatible.
Can be used without an Insteon Hub (2245-222) - included Insteon I/O Linc module (2450) communicates over powerline only, which may cause issues if you are trying to remotely operate your garage from Insteon devices on a different electrical phase (circuit) or from an Insteon Mini Remote.
Recommend adding a Range Extender (2992-222) on the same phase to bridge the I/O Linc module with Insteon RF-only or Dual-band devices.
