MAX‑E Series PWM Solar Charge Controller 10A/20A,12V/24V Auto Recognition, Positive Ground
Product Features
MAX-U series PWM solar charge controller is a positive ground solar regulator with 10A and 20A options, supporting automatic 12V/24V battery system identification. It works for multiple battery types including lithium battery, gel battery, AGM and flooded lead-acid battery. Adopting PID control algorithm, it realizes precise charging management with adjustable charging voltage and lighting control parameters.
Equipped with LCD display to show real-time working status, the controller comes with comprehensive multiple protections: overcharge, overdischarge, over-temperature, short circuit and reverse connection protection. IP32 protection grade, natural convection cooling, stable performance for long-time outdoor use.
Suitable for off-grid solar power systems, RV power supply, solar street lights and remote home power projects. We provide OEM, ODM and logo customization services, sample order is available.
