  Support PMSM motor and no need setting for the Inverter

Yx3900 series inverters for photovoltaic pumps use a new hardware technology platform and an optimized global MPPT algorithm to maximize the efficiency of equipment conversion and output communication. Applicable to all kinds of constant waterpump; support DC and AC input. When there is no solar energy, the controller can be switched to a single-phase or three-phase AC input such as a generator or utility power.

Product advantages

1. True MPPT function to ensure high efficiency;

2. Automatically DC/AC power supply switch, switch to AC supply automatically when DC supply is out. Saving maintenance work for remote area;

3. Compatable for both single phase and three phase motors;

4. Weak light function, can work under weak light conditions;

5. Max power can reach 1100kw single unit for big power application;

6. Comprehensive protection function to ensure stable power supply;
