CPN 40KW Solar Inverter for Supermarket

CPN Series 3 Phase Off Grid Solar Inverter 

Product features

1. The three-phase inverter adopts a combination of German Infineon IGBT module and high-frequency pulse width modulation technology SPWM, which has higher inverter efficiency, more stable and safe system, and long service life.

2. The inverter adopts American DSP, MCU, and DDC real-time microprocessor chips to achieve full digital circuit control and management, effectively ensuring accurate and fast operation of the core system.

3. A 7-inch high-definition LCD touch screen allows for easy human-computer interaction, viewing device operation data and working status, while also supporting query of operation records and setting of related parameters.

4. Power frequency architecture design, pure sine wave output, precision quality isolation transformer, supporting three-phase unbalanced load, with a complete machine conversion rate of over 95%.

5. The complementary function of mains and battery enables seamless switching between batteries and mains, with optional mains charging function and three-stage charging (constant current, constant voltage, float charging), which adapts to various usage needs and effectively extends the service life of batteries.

6. 3 times the peak power, strong loads capacity, and can adapt to capacitive, resistive, inductive, and mixed loads.

7. Mains/AC priority, battery/DC priority, energy-saving mode optional, and with unmanned function.

8. Equipped with complete protection functions such as AC input over voltage/under voltage, output over voltage/under voltage, under voltage warning, over temperature, overload and short circuit, battery overcharging, etc.

9. Equipped with S232/485 extended communication interface and communication module, it is convenient for users to remotely manage the power generation system.

10. WiFi remote monitoring (optional).

Working mode 

CPN series triphase inverter has two working mode: DC Priority and AC Priority 

1. DC Priority 

The inverter converts DC input current from either the PV panels or battery bank into AC current to supply the loads. When battery voltage is low, the inverter will automatically switch to the main input power (gr/generator) to supply power to the load. The system automatically switches back to AC after the battery are charged again.

(2) Battery only

(3) Only AC power

2. AC Priority 

While the AC input is stable, the inverter works in the bypass to supply power to the load and charges the battery pack at the same time. When the AC input is too high / too low / serious distortion / abnormal frequency / fault, the system will automatically switch to the battery inverter to supply power to the load. Once the AC input has been stabilized, the system will switch back to the bypass mode to supply power to the load automatically.
