GYS Power Inverter Energys Dc/dc 50.12/24
GYS 50A Dual-Battery DC/DC Charger with Integrated MPPT Solar Regulation
The ENERGYS DC/DC 50.12/24 is an advanced 12V/24V DC/DC converter engineered to optimise energy distribution in dual-battery vehicle systems. Designed for leisure vehicles, commercial vans, and specialist applications, it ensures reliable charging of auxiliary batteries using alternator and solar input simultaneously. Delivering up to 50A output with 98% efficiency, it integrates a battery isolator, multi-stage charger, and MPPT solar regulator in a single compact unit. Compatible with lead-acid (AGM, Gel, Liquid) and LiFePO4 batteries, it features automatic 12V/24V detection and a UVP wake-up function for lithium batteries. Fully compatible with smart alternators (EURO 6 vehicles), it guarantees 100% charge even with voltage drop over long cable runs. With fanless ultra-quiet operation, integrated temperature protection, and E-Mark Regulation No.10 certification, the ENERGYS DC/DC provides safe, efficient, and intelligent onboard energy management.
