Features:??Work with APP??Remote control can be realized by connecting the phone through BT, which is compatible with MOES and TUYA APP, and helps you realize flexible transfer and use between the public power and battery. The APP provides three functional values of grid power, automatic mode and inverter power, which truly defines the concept of energy-saving. (All functions of the controller are not interfered by APP.)??Surge Protecting??Timely access to the current voltage of the grid, battery and inverter, especially the current, power and power consumption of the load, performing as an intelligent power system with overcurrent protecting.??Beneficial to Solar or Wind Energy System??On cloudy or windless days, when your battery gets low, it will automatically switch to grid power for protecting your battery, especially if the battery voltage is below the cut-off point, and when the battery voltage is above the recovery point, it will automatically switch back to battery power, working like an opposite direction UPS, with an updated manual switch function for your convenience.??Auto Distinguish with Adjustable Set-points and AC Test??Direct current 12/24/48V, AC 100-120V 60HZ/220-240V 50HZ automatically distinguish, user can define cut-off and recovery voltage. Recovery voltage should be higher than Cut-off voltage. Suitable for various types of batteries, such as sealed batteries, gelbatteries, leadacid batteries, lithium batteries, etc. The battery low voltage transfer and battery recovery set points can be freely adjusted according to the battery type. Nice AC test function, when the inverter AC output is abnormal, the device will automatically switch to public power.??Bigger Power Large LCD Display??Updated rated power: 8KW(110V) or 16KW(220V) and 80A. Quick transfer time: Inverter transfer to public power 10ms, public power transfer to inverter 16ms. Designed with large LCD display for showing battery real-time voltage, working status of public power, inverter and battery.
