SAJ PDS33-4T075 – Solar inverter for pumps 75kW / 380V (3-phase)

A powerful solution for directly driving three-phase water pumps through photovoltaics - without battery, with the possibility of a backup AC power supply.

SAJ PDS33-4T075is a three-phase power frequency inverter75 kW, designed for solar pumping systems in agriculture and industry. It works directly with photovoltaic panels and does not require a battery. Thanks to the intelligentMPPT algorithmand the ability to automatically switch to a backup AC input (mains or generator), the device ensures continuous and stable operation.

Ideal for large irrigation systems and sites without access to the mains, the inverter offers easy installation, security and a long service life.

Built-in protections:
✔️ Dry run ✔️ Overvoltage and undervoltage ✔️ Overload ✔️ Blocked pump ✔️ Overheating ✔️ Short circuit

Applications:
✔️ Solar systems for agricultural irrigation
✔️ Autonomous water supply systems
✔️ Hybrid systems with backup power
✔️ Industrial installations in remote areas

SAJ PDS33-4T075 is a professional solution for large solar pump systems - with high power, stability and efficiency in all conditions.
