MPPT operation optimized for efficiency: The MPPT range is 28 55V, so PV modules with Vmp within this range are suited to achieve output efficiency. Ensure the PV module Vmp falls inside 28 55V for performance. Gridtied inverter with safety and reliability: This device is designed for gridconnected solar generation. It must be connected to a functioning power grid to generate electricity. If the grid power is out, the inverter stops generating electricity to maintain safety and compliance. Clear usage limits and compatibility: Intended to connect only PV modules. The maximum total PV input power is 500W, and the PV module voltage must not exceed 60V. Confirm that your PV array meets these limits before installation. PV module voltage compatibility: The opencircuit voltage VOC and the working voltage VMP of the PV modules must fall within the input voltage and operating range of this equipment. Practical installation guidance: When selecting PV modules, ensure that VOC and VMP are within the device's input range, and that the array power does not exceed 500W and the module voltage does not exceed 60V. This helps maintain safe operation and intended performance. Use scenarios Residential rooftop gridtied system: Install up to 500W of PV modules on a home rooftop. Connect the array to the inverter, then tie into the household electrical system with the grid to supply power when the grid is available. Small commercial storefront or office: Deploy a compact PV array up to 500W to offset daytime electrical load, connected to the grid for realtime energy generation while complying with the 28 55V MPPT range and 60V module voltage limit. Educational or demonstration setup: Use a small, compliant PV array within 500W and within MPPT and voltage limits to demonstrate gridtied PV operation and antiislanding behavior in a controlled environment.
