The 2E inverter is used for converting direct current into alternating current, with an efficiency of 90-93%. The model features many useful characteristics, including a built-in MPPT solar charge controller. The VM-5K48 provides a pure sine wave output signal (Hardwired) and switching times of 10 or 20 ms depending on the connected devices. It is compatible with generators and has built-in protection functions. Power: 5 kW / 5,000 VA. Battery connection: 48 V. Built-in chargers (mains and solar). Pure sine wave. Switching time: 10 ms (for PCs) / 20 ms (household appliances). Efficiency: 90-93%. Built-in protection functions. Automatic operating modes. Compatibility with generators. Efficient MPPT charge controller. The five-kilowatt 2E VM-5K48 inverter measures 440 × 300 × 100 mm and weighs 8.5 kg. The model is equipped with built-in mains and solar chargers; the device can be connected to a solar panel array with a total capacity of up to 3,000 W. MPPT window: 60-115 V (DC), Voc – 145 V (DC), Isc – 50 A. The inverter’s battery support is 48 V, with a maximum charging current of 120 A (combined). Suitable for small cafes or markets. Most likely, this power is more than needed for household users, but it is an optimal option for small cafes or shops. The inverter’s efficiency is 90-93%, and considering that the device is autonomous, it will use 7-10% of energy for its own operation. The switching time varies depending on the connected devices: 10 ms for PCs, payment terminals, and 20 ms for freezers, coffee machines, etc. Additionally, the inverter is equipped with RS-232 and USB interfaces for control/monitoring devices.
