Functioning Ra.Store-3 is a system for the storage of the energy produced from photovoltaic panels and the supply of the stored energy. It is possible to distinguish two different functioning modes of the system: the on-Grid mode and the EPS mode. The on-Grid mode is used by the system when the public electrical grid is functioning correctly, whereas in case of blackout the system activates automatically the EPS mode in order to solve the problem occurred, and then at last come back to the on-Grid mode when the problem is solved. In order to use the functioning mode called EPS it is necessary to install an external commutation electrical panel between the two AC electrical lines of the storage system. 3.1 ON-GRID Mode During the on-Grid mode, the electrical energy produced from the PV panels, if not consumed immediately, will charge the battery of the system and, if there will be an overproduction, it will be transferred to the public grid. On the contrary, in case the electrical energy produced from the PV panels is not enough to satisfy the needs of the consumptions, the lacking part will be supplied by the battery and, if even this will not be enough, from the public grid. During the on-Grid mode, it is possible to take energy from the battery as long as the charge of this latter is more than 20% and the power able to be taken from the battery gradually reduces when the battery approaches this percentage. This threshold guarantees a long life of the battery and an energy reserve in case of blackout of the public grid (EPS mode). 3.2 EPS Mode During the installation phase, it is possible to set the system so that in case of blackout of the public grid it supplies a part of the consumptions (the so called privileged household appliances). NOTE: The distinction between privileged and non-privileged consumptions is set by the installator (under supervision of the final user) and can be modified only by qualified technical staff. In case of blackout of the public grid, only the privileged consumptions are authorized to use the energy (energy produced from the PV panels and/or supplied by the battery). During this mode, called EPS mode, it is possible to take energy from the battery as long as the charge of this latter is more than 10% and the power able to be taken from the battery gradually reduces together with the battery status. In this mode, it is moreover active the EPS electrical socket in the electric panel of the system (picture 2, indicator 7). This mode is showed through the status 074 – EPS MODE. 3.3 Monthly recharge of the battery In order to protect the battery life, on the first day of each month the system makes automatically a recharge of the battery group up to 90%. During this activity, the system prefers to charge the battery, obviously from the panels, rather than supply energy to the consumptions. The stored energy will not be wasted away, because it is completely available for the consumptions at the end of this recharge phase. NOTE: If, during the 15 days before the first day of each month, the battery has already done a recharge up to 90%, the above mentioned recharge will not be executed. This mode is showed through the status 065 – RIGEN.RICARICA 3.4 Winter functioning of the battery (Winter mode) In order to protect the battery life, if the temperature of the battery goes down under 0°C degrees, it will be activated a charge/discharge functioning as described below. The winter functioning stops automatically when the room temperature is above 5°C. This mode is showed through the status 041 – WINTER MODE.

Statuses of the system # Code Description 68 WAITING... The system waits (WAITING) that the status of the public grid goes back to the range of the parameters fixed by the Directive in force (for ex. CEI-021). In such status, the system does not supply energy to the household appliances and does not take it from the PV panels. When the status of the public grid goes back to the range of the parameters fixed by the Directive in force, the system checks (CHECKING) that the grid stays stable for one minute. Then the system starts to supply energy to the household appliances and takes it from the PV panels (on-Grid mode). 69 CHECKING... 76 ENERGY SAVING In case the battery is run down and the PV panels do not supply energy, for ex. at night or during a very cloudy day, the system stays in standby in order to reduce its consumption. 77 ENERGY SAVING 66 OFF MODE... 2 Grid Lost.

This process deeply damages the battery modules so they can be stored for a limited period of time (max. 4 months). In the specific case a very deep discharge, ie batteries that have not undergone a charge / discharge cycle for more than a month, the discharge of the batteries can become irreversible; once the photovoltaic generator is restored they will not be able to recover. If the batteries are discharged beyond this minimum threshold, it is necessary to recharge them individually with a slow charging procedure. To avoid this, before a scheduled prolonged stop, you must contact the retailer. 8.3 RA.Store-3Bplus To deactivate the RA.Store-3Bplus expansion, lower the lever of the switches present within the accumulator electrical panel (green status indicator).
