INV-20KW

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 of the electrolyte and further prolong battery life;
• Battery tests to diagnose performance impairment or accumulator breakdowns in time;
• Management of the discharge cycles depending on the charge state of the battery. The device is compatible with the most common batteries used for photovoltaic applications characterised by a high number of charge and discharge cycles. To further optimise the performances, the Battery Care System also allows the manual setting of the voltage, current and charge duration parameters in case open-vented or NiCd batteries are used.
