Photovoltaic inverter test power supply

1. Product Introduction

NHWY-PV series photovoltaic inverter dedicated aging power supply is a DC power supply product developed specifically for aging photovoltaic inverters according to the needs of the solar photovoltaic industry. It is suitable for the debugging and aging process of solar grid connected inverters and photovoltaic inverters.
This series of power supplies has constant voltage and constant current mode outputs, can automatically cross transform, and the output characteristics are controlled by a high-speed CPU. The built-in program simulates the PV curve characteristics of photovoltaic modules, matches the MPPT control characteristics of photovoltaic inverters, and has complete protection functions. This power supply also adds preset and viewing functions for constant voltage value, constant current value, and overvoltage protection value. This series of products is also an ideal DC regulated power supply, which can be widely used in factories, schools, research institutes, laboratories, and various sectors of the national economy.
Specification range: Output power range: 1KW-480KW
Output voltage: 0-100V, 0-300V, 0-600V, 0-1000V Output current: up to 1200A
