This tester supports 0~1500V DC output, meeting the testing needs of high-voltage DC systems in new energy power stations. It can simulate 10-string photovoltaic arrays to test overvoltage, overcurrent and anti-islanding protection functions of photovoltaic inverters, and is compatible with 2MW~10MW grid-connected wind turbines to test the protection functions of wind turbine converters. The built-in 5G/Wi-Fi 6 wireless communication function enables real-time data transmission and remote control, and the IP65 protection rating makes it suitable for outdoor new energy power station sites. The built-in 10000mAh battery supports full-day on-site testing without a stable power supply.
