I want to make an inquiry


1. High frequency design with pure sine wave output(THD<3%)

2. Integrate controller and inverter to be more easy operation and easy Installation with high cost performance

3. Input and output high frequency isolation with high protection level.

4. High efficiency the efficiency of inverter is high to 90% and solar charging efficiency is high to 90%.

5. Whole function with solar charging, grid charging, grid input switch functions can be optional use.

6. Strong load capacity fit for all sensitive and liner loads.

7. Full protection functions(input low voltage protection, input over voltage protection, output over load protection, output short circuit protection)

8. Small dimensions and light weight.

9. Flexible interface for different client requirements.

Production description

GNSH series of PV off-grid inverter and controller is small power supply combining solar power discharging and inverter&controller hybrid for local market requirements. The devices have some characters of full controlling and protection,manual description,easy structure and reliable operation for 0.3KVA-5KVA power load use. For special customization, the inverter can make the controller and inverter hybrid in one cabinet. The suitable series contain car and boat load, office equipment, kitchen devices, house hold machine and electric tools to handle the technical lack in no-grid area.
