CT112S Series solar pump inverter applied in solar pump systemcan convert DC power from solar PV array to AC power to run pump motors. Inverter controls the system operation and adjust the output frequency in real-time according to the variation of sunlight intensity to realize the maximum power point tracking (MPPT).
Product Features:
-Apply to all kinds of single phase or 3 phase AC synchronous and induction asynchronous motor.
-Equipped withTI DSP digital control technique and IGBT power integration module design.
-Maximum power point tracking (MPPT) algorithm for dynamic VI.MPPT efficiency can be 99%
-Fast response speed and good stability.
-AC and DC input available, DC and AC at the same time or not same time.
-Remote control by keypad or GPRS, support RS485 protocol.
-Automatic sleep&awake function:
1)auto sleep and awake according to the high and low water level in the tank respectively.
2)auto sleep and awake according to the weak and strong sunlight respectively.
-Full protections: overload, over-current, over-voltage, under-voltage,short circuit,dry pumping etc.
-PV reversed connection protection.
-Full series book based design,
-maximizing installation space savings;
-High definition LCD keyboard,convenient for users to debug and diagnose faults;
-The whole machine features a three-proof design and PCB coating with three proof paint to ensure product stability and reliability.

CT112A Solar Water Pump Inverter is based on CT112 solar pump inverter and equipped with auto-voltage boost function to satisfy operating demands of low voltage and simplify solar battery panel configuration, reducing system cost.
CT112M mini series solar pump inverter is a small power inverter converter solar panel dc to ac power, specially for AM or PMSM solar pump control.
CT112 series solar pump inverter applied in solar pump system can convert DC power from solar PV array to AC power to run pump motors. Inverter controls the system operation and adjust the output frequency in real-time according to the variation of sunlight intensity to realize the maximum power point tracking (MPPT).
CT100 series general purpose VFD based on DSP control system, has high performance open loop vector control technology,achieving excellent performance and high reliability. It can be applied to asynchronous motors, providing excellent drive performance. Shenzhen Dolycon Technology Co., LTD Founded in 2015, we have been focusing on the research, development and sales of variable frequency drives and solar water pump inverters for more than 7 years. We are a national high-tech and professional manufacturer of various variable frequency drives and solar water pump inverters.
CT210 Frequency inverter integrates the special control logic of rotary cutting machine into itself and has integral control of rotary cutting, splitting, and splitting. It is used for the rotary cutting of wood, which has the advantages of uniform and precise thickness, accurate tail-end control, etc.
CT120G mini frequency inverter / ac drive is a general-purpose small power inverter, it is suitable for small power motor adjusting speed. China professional frequency converter supplier & factory.
CT100F PMSM vector control inverter adopts original magnetic pole detection technology to realize soft-start, no reverse, or joggle, meet high requirement application.
CT112M mini series solar pump inverter is a small power inverter converter solar panel dc to ac power, specially for AM or PMSM solar pump control.
