Frequently Asked Questions

What is the typical lead time for a wholesale order of the Residential PV Battery Integration Kit?

For standard orders, the lead time is 15-20 working days after order confirmation and deposit. Our robust inventory of core components allows us to expedite delivery for urgent projects.

Can this system operate independently (off-grid) during a power outage?

Yes, the Residential PV Battery Integration Kit features a seamless transition mode. It can switch to an off-grid backup mode within milliseconds, providing immediate backup power to critical loads. For full off-grid capacity, please ensure your inverter configuration is compatible.

How does the 10-Year Performance Warranty work, and what does it cover?

Our 10-Year Performance Warranty guarantees that the system will maintain at least 70% of its initial usable capacity. It covers all major components, including the LFP battery cells and BMS. Our dedicated global service team is available for full support, including part replacement and remote diagnostics.

Is this kit compatible with my existing PV inverter and solar panels?

It is designed for broad compatibility with most hybrid and battery-ready PV inverters. We recommend reviewing the communication protocols (CAN/RS485) and voltage parameters listed in the specifications table. For specific compatibility questions, our technical pre-sales team can provide detailed integration guidance and checklists.

What are the storage and operating temperature requirements?

The RPIK-5.12L is engineered to operate efficiently within a broad temperature range of -20°C to +55°C. The built-in liquid cooling system ensures stable performance, even under high ambient temperatures, while the advanced BMS actively manages thermal runaway risks. For long-term storage, we recommend a cool, dry environment between -10°C and +35°C.
