1. Giriş
This TOOLTOP multifunctional solar MPPT tester is a highly efficient, portable device designed for on-site testing of photovoltaic (PV) modules. It accurately measures key parameters such as maximum power (Pmax), open-circuit voltage (Voc), and short-circuit current (Isc) with an accuracy of ±1.5%. The device supports testing of high-power modules up to 2000W.
The ET275 model also integrates a 2000V high-voltage digital multimeter, offering 60,000 counts for precise and reliable electrical measurements. Both models are equipped with a 1500mAh rechargeable lithium battery for extended use in industrial environments.
Key features include a large 3.2-inch (240x320 resolution) color screen, comprehensive protection mechanisms (overvoltage, overcurrent, reverse polarity, overtemperature), and automatic test data saving. It is an essential tool for PV module production, acceptance testing, and operational maintenance, facilitating rapid fault diagnosis and improving testing efficiency.
