CTECHi Technology Co. Ltd

Introducing our 30A MPPT Solar Charge Controller 12/24V Auto - Negative Grounded Model, the ultimate solution for efficient and intelligent charging in dual battery systems.
Designed for vehicles and similar systems, this DC-DC intelligent charger/controller optimizes power generation from both motor (ordinary/smart alternator) and photovoltaic sources. By combining the advantages of motor and solar power, it ensures maximum efficiency in charging your batteries.
Featuring advanced functionality, this charge controller prioritizes the charging of the main/service battery by default, utilizing solar input. Once the main battery is fully charged, the controller seamlessly switches to charging the auxiliary/starter battery automatically. Moreover, users have the flexibility to adjust the charge priority between the main and auxiliary batteries using the external remote LCD screen. With customizable settings, you can tailor the charging process to suit your specific requirements.
In addition, the auxiliary battery can also be utilized to charge the main battery, either through settings in the controller or via the IGN alternator. This innovative feature enhances versatility and ensures optimal utilization of available power sources.
Experience seamless and intelligent charging for your dual battery system with our 30A MPPT Solar Charge Controller. Maximize efficiency, optimize power utilization, and ensure reliable performance on every journey.
