GQH-PB Parallel DC Power System
GQH-PB Parallel DC power system innovatively designs a “parallel power module” that combines a 12V single battery with parallel modules (including AC/DC, DC/DC charge-discharge conversion, and battery management). Multiple modules are paralleled to form a parallel-type DC power supply system. Each parallel power module operates independently, so the failure of a single module does not affect the overall operation of the system, achieving fine management of each battery cell and improving system reliability.

Reliability
GQH-PB features complete isolation between batteries, AC bus, DC bus, and other batteries. A single power module can be individually serviced and replaced in case of failure without affecting the normal operation of the system.
Online full-capacity testing of batteries
The parallel power modules independently manage the charge and discharge of batteries. Combined with monitoring, they conduct periodic online capacity testing to detect abnormal batteries early, effectively extending battery lifespan.
Cost-Effective
Supports mixed use of new and old batteries, enhances asset utilization, reduces the need for battery spare parts procurement, and contributes to energy conservation and emission reduction efforts, helping achieve energy efficiency and carbon reduction.
