Frequently Asked Questions (FAQ)

Q: How is MPPT better than PWM?

A: MPPT can harvest 15-30% more energy from the same solar panels compared to PWM, especially in cold weather, cloudy conditions, or when battery voltage is significantly lower than panel voltage.

Q: How do I connect to WiFi?

A: Download the JYINS monitoring app, connect to the controller's WiFi hotspot, configure your home WiFi network, and start monitoring. The app supports remote access via cloud server.

Q: Can I use different solar panel voltages?

A: Yes, MPPT controllers can accept higher panel voltages (up to 100V/150V) and efficiently convert to battery voltage, allowing series panel connections for reduced cable losses.

Q: Is the app free?

A: Yes, the JYINS Solar Monitor app is free for iOS and Android with no subscription fees. Cloud remote access is included.
