Q : 1. What is a hybrid solar system? A : A hybrid system combines solar panels, batteries, and a hybrid inverter. It stores energy for later use and works with or without grid power.
Q : 2. How does a hybrid system operate during outages? A : When the grid goes down, the system automatically powers essential loads using stored solar energy to keep your home running smoothly.
Q : 3. Can this system power a large home or small business? A : Yes. With up to 25kW output and 200kWh of storage, it easily supports high-consumption applications.
Q : 4. What makes this system “all-in-one”? A : It includes panels, hybrid inverter, BMS-integrated lithium batteries, and smart controls—ready for installation and operation.
Q : 5. What type of electrical output does it support? A : It provides three-phase AC output (230/400V, 127/220V, or 277/480V), compatible with international grid standards.
