    ET-RC, at a glance

    13 Indicators LCD Controller

    ET-RC is a new 3.0 generation controller of inverters from EDECOA, which is upgraded with imaginable functions.  This time there are 13 indicators on the screen. Besides the voltage and Amp of both input and output and the output frequency and output frequency, it displays the battery capacity, load volume, inverter internal temperature, and fans' working status in real-time figures. Different error codes and alarm statuses will be displayed on LCD as well. You know what's going on with your system at a glance. 


    Make the alerts visible

    Visible alarm figures

    ET-RC has an independent high-speed MCU, which ensures its real-time and accurate signal source. Working together with the multi-protection and imaginable alarm design, the controller provides you with an insight view of your system. For example, once the battery voltage is too low, the smart buzzer will be beeping, and the battery capacity figure will become empty and flash. From now on, system alert indicators are not only soundable but also visible.

    ET-RC is more than a controller

    Dual USB ports

    If you are tired of belting down to find the USB port on an inverter or found it inconvenient to pass through cables before plugging in a USB socket, then you will definitely like the USB ports provided on the ET-RC controller board. Both USB ports are 5V 2.1A. They are compatible with most of the devices. The most important point is that the current for these ports is controlled by an independent MCU and transported through an independent line, directly from your battery supply. You will never have an interruption issue with ET-RC.

    Anodized Aluminum Outcast

    The anodized aluminum casing isn’t only beautiful and has good heat dissipation performance, wear resistance, insulation, and durability. It's the best choice for a tough environment.

    Galvanic Isolation

    Safety Galvanic isolation was applied to the internal electrical power sections between DC and AC sections/subsections, by which non-direct current can flow and may possess different ground potentials.

    • Q: Is this compatible with lithium batteries that charge to 14.6V?
    • No. The working DC input voltage of the 3500w 12v pure sine wave inverter is 10.5V~15.5V.
    • Q: Where do I ground the inverter to? If my batteries are grounded, do I even need to ground the inverter?
    • If using the power inverter at home, the ground should be connected to the ground stake. If using the power inverter on the caravan/automotive, the ground could be connected to the battery’s negative terminal. If any questions, please feel free to contact our customer service team.
    • Q: What is the warranty on this product?
    • We provide a 12-month warranty for each order from the purchased date.
    • Q: Does this have a battery protection logic so you don’t completely drain your batteries?
    • Thanks for your interest. The inverter has low input voltage protection. When the DC input voltage is less than 10.5V, the inverter will stop working.
    • Q: Can the remote control be used to start the unit if the main switch is off?
    • Yes, the remote only works when the main switch is off.
    • Q: Do the fans turn off when there is no load?
    • All EDECOA inverters have a smart fan design to save your battery power. There is a temperature sensor built in the power inverter. The fan will only start to work when the internal temperature is over 45°C/113℉. When it is over 75°C/167℉, the inverter will shut down due to overheating protection to protect the inverter.
    • Q: How long are the red and black power cables that come with the unit?
    • The cable that comes with the inverter is two pairs of 16mm2 and the length is 600mm(3 AWG/1.97 FT.). Any questions, please feel free to contact us.
    • Q: Does this inverter have internal breakers or fuses or does it have to be connected to an ac breaker box to run loads?
    • This model has twelve built-in DC 30A fuses. If you want to add a breaker between the battery and the inverter, a 250A breaker is recommended.
    • Q: What is this device’s THD (%)? what is its no-load current draw?
    • The THD is <3% (Linear load). Its no-load current is less than 0.7A.
    • my charge controller goes thru equalize cycle at 30 v, will this inverter protect itself from over-voltage input?
    • Q: If your controller is compatible with your battery, which means the maximum charging current is within 0.3C and you connect the inverter with the battery, then the inverter will work fine. Even the charging voltage is higher than 31V.
    • Q: Does each ac outlet have a power limit?
    • Only in the sense that the total wattage for all the outlets combined must not exceed 3500 Watts, and the outlet itself is designed to work within 16A which means one single outlet has an output limitation of 2000 Watts. So this model provides an extra output AC wiring terminal.
    • Q: Is this a low-frequency design?
    • This model is a high-frequency design power inverter.
