Moreday Solar MDHL AC combiner box Ip65 waterproof level

Reliability and availability are paramount for solar installations in the PV industry. In systems with string inverters, our AC combiner boxes provide optimum short circuit and overvoltage protection. In addition, each string inverter can be easily disconnected from the system for maintenance.It housed in waterproof box is suitable to be used in outdoor and indoor for diverse environment.


Product Detail

Product Tags


The new PV AC Combiner boxes have been designed for PV systems with string inverters in trackers or fix tilt systems.The product portfolio is suitable for inverters from 5 kW up to 200 kW and support voltages of 220V, 400 V, 690 V or 800 V AC. The combiner boxes allow to collect from 2 up to 12 string inverters in one single cabinet. They withstand ambient temperatures from -20 up to +50°C to operate in hardest climate conditions, fulfilling the highest market standards as per IEC 61439-2 ed 3.0:2020.

MDHL Series AC combiner box provides cost-effective means to combine AC equipment. The box body is made of cold rolled steel and other metal materials. Individual fused inputs facilitate string inverter output aggregation. This series support all string inverters and are highly configurable to fit any application.
