Thanks to its rated power of 20,000W and maximum apparent power of 22,000VA, it offers superior performance with a maximum efficiency of 97.6% and MPPT efficiency above 99%. Its architecture includes two MPPT trackers with a wide voltage range (150–850V), ensuring optimal energy capture even under variable irradiation conditions.

This solar inverter is compatible with lithium-ion batteries (160–700V) and allows a maximum charge and discharge current of 50A. It also supports connection to diesel generators, making it ideal for hybrid or off-grid systems.

One of its standout advantages is the 100% unbalanced output per phase, allowing adaptation to irregular loads without compromising performance. It also offers 6 programmable battery charge and discharge periods, optimizing energy use according to user needs.

For safety, the inverter incorporates multiple protection systems: DC reverse polarity, overcurrent, overvoltage, short circuit, ground faults, isolation monitoring, anti-islanding protection, and type II surges (DC and AC).

It complies with international standards such as IEC, CEI, EN, VDE, RD 140, and UNE 217002, ensuring reliability and regulatory compliance.
