The UY-MPPT-450DC is a 450W wide-voltage buck-boost integrated MPPT solar charger launched by Yunyang Electronics. It features a rated maximum charging current of 20A and is compatible with three major energy storage battery types: lithium iron phosphate, ternary/lithium manganate, and lead-acid batteries. Custom voltage versions (12V/24V/36V/48V/60V/72V) are available upon request.
Equipped with high-performance MPPT maximum power point tracking algorithm, this unit accepts an ultra-wide PV DC input range of 9–100V and automatically switches between boost and buck modes. It suits a wide range of applications including RVs, watercraft, off-grid outdoor energy storage, solar monitoring systems and compact energy storage power stations.
Constructed with an integrated aluminum alloy housing, it comes with a built-in digital display meter and multi-layer hardware protection circuits. Featuring a compact footprint for easy installation, all cable specifications can be customized as required, delivering reliable industrial-grade performance and outstanding durability for outdoor environments.
