Easy installation and maintenance:

• The product's compact design, consisting of a single mechanical unit, saves on installation costs. Thanks to the connectors on the outside of the inverter, installation is quick and easy, with no need to open the front cover. In addition, the absence of fuses ensures savings in maintenance costs and time, reducing on-site interventions to a minimum.

Maximum flexibility and integration:

• Its input voltage range and connection system provides flexibility to the inverter and makes it suitable for both new installations and retrofit projects. The new inverter family ensures maximum integration with the latest technologies in the PV field, including double-sided modules.

Advanced communication:

• Fast commissioning thanks to the Installer for solar inverters app, which allows multiple inverters to be commissioned simultaneously, saving up to 70% of commissioning time. The monitoring of the currents of the individual strings allows the status of the photovoltaic generator to be kept under control and any faults to be detected in real time. FIMER's Export limitation solution is standard and allows you to meet the power export limits imposed by utilities, without the need for additional external devices.

Integrated PID recovery function:

• The inverter with integrated PID (Potential Induced Degradation) recovery function, is able to re-establish the optimal conditions of the photovoltaic panel in order to prevent the loss of performance that the PID could cause during normal operation. This feature allows you to maintain an optimal level of performance with the effect of maximizing the life of the system and therefore the return on investment.

Integrated arc interruption system:

• The Integrated Arc Detection System (AFCI) allows for the immediate detection and interruption of any occurrence of an arc on the PV generation system. With this feature, the inverter is able to provide a reliable fire prevention mechanism where required for rooftop PV systems.

RSD compatibility:

• The PVS-10/33 inverter is tested to work with photovoltaic systems where there is the presence of rapid electrical disconnection (RSD) systems or I-V operating point optimizers at the individual module level (contact FIMER for a list of compatible systems).
