1 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).

5. Working mode of CPM
CPM series 3-phase solar inverter transformer based unit has five working modes: DC priority, AC priority(A), AC priority(B), INV On and INV Off.
5.1 DC Priority (Must be connected with batteries)
The inverter converts DC input current from either the PV panels or battery bank into AC current to supply the load. When battery voltage is low, the inverter will automatically switch to the main input power (gr/generator) to supply to the load, but won’t recharge batteries with AC power. The system automatically switches back to DC after the batteries are charged by PV again.
5.1.1 PV with battery bank (when PV is sufficient))
5.1.2 Battery only (when PV is not available, but battery power is sufficient)
5.1.3 AC only (when PV is not available, and battery power is insufficient)
