NB10kT On-grid inverter

NB10kT On-grid inverter
Product Detailed
Inverter: 1 Max.conversion efficiency of 94.5%; 2 Using an accurate MPPT technology; 3 Key parts are exported.

NB10kW ON-grid Inverter

Features:

The control microprocessor built in NB10KT inverter is two pieces of the latest world famous brand 16-bit MCU chip, which is suitable for floating point arithmetic and has a better open and close loop control in the inverting process due to the advantages of lower self consumption, faster calculation and more accurate sampling. The IGBT selected is the latest Infineon product that will further improve the efficiency and stability because it is more stable and has lower switching loss. In control arithmetic, comprehensive applications of space vector PWM technology, optimal efficient data process method, fuzzy PI control theory and humanized design thought have ensured the product features of high quality, stability, reliability and affinity.

Advantages:

1  The power unit is well designed with heat flow simulation, which has a better thermo-stability than traditional one. The controlled air cooling and efficient air flue design has not only effectively reduced the energy loss but also decreased the self loss of inverter, therefore to extend the `lifetime of power unit.

2  The well proven voltage loop and current loop control technology, which is critical to high efficiency conversion, has maximally drawn energy from the polar PV module with the efficiency  reaching 94%.

3  Perfect active and passive solution of "island detection" has been used, which is significant to protect the safety of maintenance people and equipment. 

4  Perfect protection solution of circuit breaker and contactor designed at both AD and DC side for emergency case.

5  With optimally selected components, the system can work in different environment conditions. It has the ability of high altitude and low temperature start. The assistant heating function is optional. 

6  It has a friendly human-machine interface and touch screen operation display. It built with different optional communication interfaces. With abundant statistic data, it is able to simultaneously remote measure and control several inverters equipped with the “plant monitoring” software.

7  Modular design, easy for daily maintenance and management.
