| High Light | off-grid inverter charger 3500W ，KRP series inverter charger ，DC AC inverter with warranty | ||
The KRP Series is a versatile off-grid inverter charger, ideal for residential, school, healthcare, and government facilities, as well as areas with inconsistent electricity supply. It supports dual AC output, solar charging, and utility integration, providing reliable and efficient energy solutions.
What sets the KRP Series apart is its enhanced PV Max. Input Current capacity, accommodating 20A for single PV input or 20A+20A for dual PV inputs. This makes it an excellent choice for installations requiring higher solar input capacity while maintaining the same core features as the KR Series.
With a capacity range of 3500W to 5500W, the KRP Series supports single-phase or three-phase parallel operation with a modular design for easy installation and expansion. Its comprehensive electronic protections and durable construction ensure dependable performance in a wide range of environments.
The KRP Series is a robust and flexible solution for managing your energy needs, offering enhanced compatibility for larger solar installations while maintaining the trusted performance of EPEVER’s inverter/charger lineup.
