2�- PRODUCT DESCRIPTION

The

CirPower Hyb

is a 4 kW hybrid inverter that works like a power management system by

managing energy flows between solar panels, batteries, power loads and the grid.

The device uses various power management strategies to adapt to the needs of the user. It

uses applications both outside the grid and applications connected directly to the grid.

The device features:

- Communications via

RS-485

to communicate with an external analyzer.

- An

Ethernet

connection for remote control of the inverter.

A touch screen

Display

to view and set up unit parameters.

- Plug-in connectors for an easy and quick installation.

- All-in-one solution, with solar converter, grid/AC inverter and bi-directional battery

charger.

- A patented system that guarantees connection / disconnection transfers from the grid

without voltage drops in the loads connected to the inverter.
