Inverter 2E is a converter of direct current into alternating current, with an efficiency of 90-93%. The model has built-in solar and grid charging devices. VP-3K24 is designed for single-phase networks, providing a clean sinusoidal output signal and a switching time of 10 or 20 ms depending on the type of connected devices. Power 3 kW / 3,000 VA Possibility of connecting a 24 V battery Built-in charging devices (grid and solar) Clean sinusoid Switching time: 10 ms (for PCs) / 20 ms (household appliances) Efficiency 90-93% Charging priority selection Automatic operating modes Built-in protection functions Compatible with generators Clean sinusoid and high efficiency With dimensions of 420 × 390 × 193 mm and a weight of 7.8 kg, the model has a decent power output of 3 kW (3,000 VA). The design includes a built-in solar charger, allowing the inverter to be connected to a solar panel array with a power of up to 1,200 W. VP-3K24 is autonomous, and any type of 24 V DC battery can be connected to it, with a maximum charging current of 70 A (combined), which determines the speed of external battery charging. The inverter provides a clean 230 V sinusoid (Hardwired) in battery operation mode. Regarding the signal from the solar panels: PWM window - 60 V DC. Automatic operating modes and charging priority selection The inverter's efficiency is 90-93%, meaning that the device will "consume" 7-10% of the energy for its own maintenance. 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 built-in display and buttons for setting the charging priority or automatic operating modes, as well as protection functions for safe device use. As for interfaces: the inverter is equipped with USB and RS-232 ports.
