Frequently Asked Questions

What is the difference between MPPT and PWM solar charge controllers?

MPPT (Maximum Power Point Tracking) controllers are more efficient, especially in cold or low-light conditions, and can increase energy harvest by up to 30% compared to PWM (Pulse Width Modulation) controllers, which are simpler and more cost-effective for small systems.

Can your inverters work with lithium batteries?

Yes, our pure sine wave inverters are fully compatible with lithium (LiFePO4) batteries and can be configured with appropriate charging parameters for safe and efficient operation.

Do you offer OEM/ODM services?

Yes, Top Green Energy provides comprehensive OEM and ODM solutions including custom branding, packaging, and product specifications tailored to your market needs.

What certifications do your products have?
