The H-FSP 7-340 inverters are starter and management panels for solar pumping systems, consisting of a suitable market inverter modified for this type of operation. Designed for 400VAC three-phase motors, they vary in size according to each electric pump rating, from 7.5 hp to 340 hp.

They feature two inputs: a priority DC input, from 4 to 64 strings depending on the power, and a secondary 400V AC input for hybrid operation, integrating grid power with the energy produced by the solar panels to operate at the maximum set frequency.

Both inputs are equipped with a door-lock isolator switch on the front panel, while inside the panel there are fuses for each string and phase, suitably sized. As standard, they are fitted with a dedicated inductance for each motor size, suitable for cable lengths up to 300 m; versions for longer cable lengths are also available on request.

These systems must be installed by qualified personnel, as they are electrically complex installations. The software is preset and the inverter is ready for use.

INTEGRATED FUNCTIONS

• DC input from 4 to 64 strings with fuses and isolator switch
• 400V AC 50/60 Hz input with fuses and isolator switch
• MPPT software to use all the energy produced by the panels at any time
• Possibility of use in PID mode (constant pressure)
• On-Off control via one or more floats/pressure switches
• Load self-limitation
• Internal temperature control, reducing the load in case of overheating due to external factors
• Dry-running control via Cos-phi or level probes
• GSM/GPRS remote control
• DV/TV filter for motor protection with cables up to 300 m
• IP54 (indoor installation recommended)
• Maximum ambient temperature 40°C (50°C on request)
