DQ1906 Residential Storage System FAQs

DQ1906 is rated IP20 and is designed for indoor installation. For outdoor applications, an additional protective enclosure or installation in a sheltered equipment room is required.

Yes. The system supports simultaneous charging and discharging for dynamic energy management. For example, if PV input is 4kW and load demand is 3kW, the remaining 1kW can be used to charge the battery.

For example, the DQ1906B5K6-02 supports up to a 1C charge rate and can be fully charged in approximately 1 hour under ideal conditions.

Installers should calculate string voltage based on the panel Voc at the lowest ambient temperature to ensure it does not exceed the 450V limit. It is recommended to use up to 8 panels in series per string and no more than 3 parallel strings for optimal safety and performance.

Integration depends on the existing system architecture. DQ1906 is best suited for new installations or as a standalone subsystem. For retrofit projects, compatibility with existing inverters, grid control logic, and protection schemes must be carefully evaluated to avoid system conflicts.

In regions with high electricity prices and favorable net metering policies, the payback period is typically 5–7 years, while in lower-cost regions it may exceed 10 years.
