The autonomous inverter 2E SM-4K224T is designed for uninterrupted power supply to facilities located away from the centralized power grid, especially relevant during phase-out or emergency power outages. Its wide range of applications is due to its design features: the model has built-in grid and solar charge controllers, protection functions, and an available priority charging selection. Moreover, the device is compatible with generators! Power 4.2 kW / 4200 VA Ability to connect a 24 V battery Built-in chargers (grid and solar) Pure sine wave Remote control capability Integration into the "Smart Home" system Compatibility with generators Built-in protection functions Priority charging selection Pure sine wave for "precision" equipment operation A pure sine wave signal is crucial for the proper functioning of "precision" equipment (pumps, boilers). In case of emergency power outage or unstable grid operation, an autonomous inverter with a capacity of 4200 VA providing a pure sine wave of 230 V (Hardwired) in battery mode will be useful. For connection to a FE-array with a maximum power of 5000 W, an integrated MPPT controller (MPPT window: 60-450 V DC) is provided. Additionally, if necessary, batteries of various types 24 V can also be connected to the inverter, with a maximum charge current of 120 A (combined). Interfaces for Smart Home The technical capabilities of the SM-4K224T model are complemented by a wealth of interfaces: for connecting a PC or controllers of the "Smart Home" system, RS-232/485 ports are used; remote device management can be performed via Wi-Fi; the Dry-contact technology allows setting certain conditions (scenarios) for automatic inverter activation, and of course, it includes the familiar USB-OTG.
