• Compatible with On-grid and Off-grid systems • Quality power supply to loads with the integration of photovoltaic energy • PV plants integration with Aros inverters Sirio Power Supply is a device that can both increase the functionality of an On Grid photovoltaic system with AROS Solar Technology inverters as well as create an Off-grid system. In fact, thanks to energy storage which is suitably sized based on the desired load characteristics and battery life, the system can store energy produced from a renewable source which can then be used later or when there is no radiation, in addition to making the system independent of the existence of electricity distribution grid. Hence this solution allows the self-consumption of the energy produced by the centre's photovoltaic system to be managed in the best possible manner. The battery charging is done from the photovoltaic inverter or the electric grid/ generating set. The generous dimensions of the main internal components allows a higher output value to be obtained and, to guarantee the system performance, the presence of the inverter's output transformer ensures the galvanic separation between the load and the batteries.

Battery Care System The monitoring and management of the accumulators is transferred to the Battery Care System program which can safeguard the efficiency and reliability of the batteries with following services: • absence of ripple current with charged battery; • charging at two voltage levels to optimise the charging current and reduce the capacity recovery times; • compensation of the charging voltage depending on the temperature and protection against deep discharge, to reduce the phenomena of ageing and prolong battery life; • monitor the maximum charge time to reduce the consumption...

Condition no. 3 In case of insufficient sunlight and a discharged (or inhibited) battery, the load is powered by the grid through the inverter or the bypass (energy saving mode). Sirio Power Supply Sirio Power Supply On-Grid system without option of net metering Condition no 1 In case of sufficient sunlight, the FV inverters supply the load and charges the battery from the SPS output; thus even if the mains supply is not available. If the load is transferred to the bypass due to a malfunction in the SPS or a current spike that is above permitted levels, the FV inverters are immediately...

Off-Grid system with generating sets or equivalent Condition no. 1 In case of sufficient sunlight, the FV inverters supply the load and charges the battery from the SPS output; thus the generating sets can be switched off. Sirio Power Supply Condition no. 2 In case of insufficient sunlight, the load is supplied by the FV inverter with the aid of the battery. For optimum use of generating sets, the battery discharge level can be set. Sirio Power Supply Condition no. 3 In case of lack of sunlight, the FV inverters are switched off and the battery discharged; the load is supplied by the...
