Solar Off Grid Controller Inverter 3kW

Technical Characters:

High-frequency conversion and Tandem PWM control Technology, High conversion efficiency

A "point-type" control and current and voltage pairs of closed-loop control, maximizing charging capacity from PV module to battery, improving charging efficiency

Part of unit has LED, LCD display, timely monitoring and displaying battery voltage, load & charging current, daily power generated and discharged amount, total power generated and discharged amount, load shortage times, environment temperature, AC output voltage & current and so on.

System is programmable for parameters of battery, PV module, system and time.

Part of units has RS232/RS485 connect interface

System has RTC function, would be able to check current time and manage to change the time parameters

Man-machine interface LCD could display working parameters and faults for some units

Setting to open/off machine function

Controller and inverter in one body, with bypass Grid power connection as option

Charge and power use in the same while when day time, reliable output voltage and frequency

Multi protection functions, over charge & discharge, over load, shortage, Reverse polarity, over voltage, over heat protections or warning buzzer. And all protection would be auto recover itself. Safety meet: IEC61173, IEC 60529, IEC 62109 and so on

Economy:

The new energy powers are generally high costs, solar PV panel is expensive, to improve efficiency of power machine would properly save solar panels and reduce investment

Easy design:

The power machine integrates controller, inverter and necessary electric parts together in one body, easy diagram, save cost but multi functions
