Frequently Asked Questions
Everything you need to know about this product.
The Huawei SUN2000-12/15/17/20/25K MB0/MAP0 series typically comes with a standard 10-year warranty, which can be extended up to 20 years depending on your installation package and agreements with Trexon Energy.
Yes, the SUN2000 is inherently 'Battery Ready'. It features a plug-and-play interface specifically designed to integrate seamlessly with the Huawei LUNA2000 Smart String Energy Storage System without needing extra hardware.
The AI-powered AFCI continuously monitors the DC circuit for specific noise signatures that indicate an arc fault. If detected, it shuts down the inverter in just 0.5 seconds, effectively preventing electrical fires before they start.
Absolutely. When paired with Huawei Smart PV Optimizers, the system independently tracks the maximum power point (MPPT) for each module, recovering up to 30% more energy from shaded or mismatched panels.
Yes, it boasts an IP66 protection rating, making it completely dustproof and highly resistant to heavy rain. Its advanced thermal design allows it to operate safely in extreme environments from -25°C to +60°C.
When combined with a Huawei LUNA2000 battery and a SmartGuard backup box, the system provides automatic, seamless backup power to your critical home appliances during grid outages.
