Inverter 2E is a converter of direct current to alternating current, with an efficiency of 93%. The model has built-in solar and grid charging devices. VM-3K24 is designed for single-phase networks, providing a clean sinusoidal output signal and switching times of 10 ms and 20 ms depending on the type of connected devices. Power 3 kW / 3,000 VA. Ability to connect a 24 V battery. Built-in charging devices (grid and solar). Clean sinusoid. Switching time: 10 ms (for PCs) / 20 ms (household appliances). Efficiency 93%. Compatibility with generators. Charging priority selection. Built-in protection functions for both the network and the solar panel array. With dimensions of 473 × 297 × 107 mm and a weight of 7.4 kg, the model has a decent power of 3 kW (3,000 VA). The design includes a built-in solar charging device, allowing the inverter to be connected to a solar panel array with a power of up to 1,200 W. VM-3K24 is autonomous, and batteries of different types of 24 V DC can be connected to it as needed, with a maximum charging current of 65 A (combined), which determines the speed of charging the external battery. Unstable input AC 170-280 V (Hardwired) is converted by the inverter to a clean sinusoid of 230 V (Hardwired). Regarding the signal from the solar panels: MPPT window - 115 V DC. High efficiency and low self-consumption. The inverter's efficiency is 93%, meaning that the device will "consume" 7% of the energy for its own operation. For household use, a device of this power will be sufficient to power a refrigerator, boiler, television, washing machine, and provide home lighting. The switching time varies depending on the type of devices: 10 ms (for PCs) and 20 ms (household appliances). The design includes a display and buttons for selecting charging priority, built-in protection functions. As for interfaces: the inverter is equipped with USB and RS-232 ports (for connection, for example, to a PC).
