The SolarMax 300 TS solar inverters have a rated output of 300 kW and operate in the MPP range of 430-800 V.
Sputnik has boosted the efficiency of the previous model, the SolarMax 300 C solar inverter, from 94.8% to 95.5%.
Unlike the SolarMax 300 TS, Sputnik's SolarMax 330TS SV operates without a low-voltage transformer.
Up to four of the new 330 kW inverters can be integrated into a SolarMax power station and their power fed directly into the medium-voltage mains via a medium-voltage transformer.
As with other SolarMax-TS series devices, the electronic system monitors the IGBT switches of the two new solar central inverters on the power unit.
Sputnik also replaced the electrolyte capacitors with film capacitors where possible to increase the devices’ lifespan. The optional earth-kit also permits the inverters to work in combination with thin-film or back-side contacted solar modules.
