Frequently Asked Questions
Q: How does a 5kW off-grid solar home system work?
A: The system converts the DC power generated by the solar panels into AC power via an inverter, providing independent power for the home. The power is stored in batteries for use at night or on cloudy days.
Q: How should the batteries be maintained?
A: Batteries should be kept dry and at a suitable temperature. The voltage and electrolyte level should be checked regularly, and over-discharge or over-charge should be avoided to prolong their lifespan.
Q: What precautions should be taken when installing solar panels?
A: Panels should be installed on an unobstructed, well-lit roof or ground surface. They should be securely fastened and tilted to optimize sunlight absorption.
Q: How does the system ensure safety?
A: The system is equipped with overload, short-circuit, and reverse polarity protection. Regular inspection of the wiring and connectors can effectively reduce safety risks.
Q: How often should the solar panels be cleaned?
A: We recommend cleaning them quarterly. Wipe with a soft cloth and clean water to avoid scratching the panels with a hard brush.
Q: What parts of the system require regular inspection? A: Mainly check the panels, inverters, batteries, wiring and bracket bolts to ensure that the connections are tight, the voltage is normal and there are no water leakage hazards.
