MODULAR POWER SUPPLY SYSTEM

The claimed system relates to electrical equipment and comprises a module that includes a module docking unit (), a remote control device (), electrical connectors () for connection to sources of alternating current (AC) and direct current (DC), and electrical connectors () for connection to an AC load and to a DC load. The electrical connector () for connection to an AC source is connected, via a unit () for switching a supply of electrical energy from an AC source, to the electrical connectors () for connection to an AC load and to an AC/DC converter (), and the electrical connector () for connection to a DC source is connected, via a unit () for selecting a maximum output from solar panels and a unit () for determining a drop in voltage from the DC source, which are connected in series, and by a storage battery charging unit (), to a first DC converter () which steps up and stabilizes the voltage. The storage battery charging unit () is connected, via a battery management system unit (), to a storage battery unit () connected to the first DC converter (), the latter being connected to the electrical connectors () for connection to an AC load via an inverter () having the function of switching off the supply of DC electrical energy thereto, and to the electrical connectors () for connection to a DC load via a second DC converter () which steps down the voltage. The invention allows more stable and reliable functioning of the power supply system and could be used as independent power supply system with combination of photovoltaic panels.
