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 chargers. VP-1K12 is designed for single-phase network, provides a clean sinusoidal output signal, and a switching time of 10 or 20 ms depending on the type of connected devices. Power 1.0 kW / 1,000 VA Possibility to connect a 12 V battery Built-in chargers (grid and solar) Clean sinusoid Switching time: 10 ms (for PCs) / 20 ms (household appliances) Efficiency 90-93% Built-in protection functions Compatibility with generators Automatic operating modes Built-in protection functions for safety Power of the model is 1,000 VA. The standalone inverter can be connected to conventional sources of alternating current such as car batteries, as well as to photovoltaic arrays (solar panels) with a power of up to 600 W. The device outputs a clean sinusoidal signal of 230 V (~50/60 Hz, Hardwired). Moreover, an external 12 V battery of any type (Carbon, Li-Ion, Li-Pol, LiFePO4, Li-TiO, OPZS, OPZV, etc.) can be connected to the VP-1K12, with a maximum charging current of 50 A (combined). The inverter has built-in protection functions and automatic operating modes. Compatible with generators The efficiency of the 2E VP-1K12 inverter is 90-93%. It is equipped with standard USB and RS-232 interfaces for control. The switching time is variable (10 ms / 20 ms) and depends on the type of connected devices. The model will be useful for solving simple tasks in case of emergency power outage, such as powering a boiler or refrigerator, or at a summer cottage where there is no centralized power grid, as it is compatible with generators.
