Hanut India : Solar Inverter output combiner boxes

Solar ACCB [AC combiner Box] are also called inverter combiner panel.

Solar ACCB [AC combiner Box] are used in large solar PV power plants where there are several solar power inverters. ACCBs have one MCCB for each inverter and one master MCCB at the outgoing side. Combined output from the AC combiner panel is normally sent to the step up power transformer for feeding to the grid at 11 /33 / 66 / 132 kV level.

Hulasi has supplied small ACCBs with master MCCB of 100A to large ACCBs with master ACBs of 2500A rating. Hulasi has provided 2500A capacity AC combiner [ACCB] panels for a MW scale solar power plant in Rajasthan. Each ACCB panel had a 2500A output ACB and 10 input MCCBs of 250A.

[October 2021] MEGA order received for supply of 800V solar MCCB panels for deployment in Gujarat. Each solar panel has 9 feeders of 400A with operating voltage up to 800V AC and one compartment for LV 415V switch gear. 800V solar AC combiner panels by Hulasi are already deployed in solar PV plant in Bikaner, Rajasthan.

The 800V solar AC combiner boxes are becoming popular along with 1500V DC inverters as solar power transmission at higher voltage [800V v/s 400V] significantly reduces the power losses and also the installation costs.

Hulasi is one of the few companies in India to offer solar AC combiner panels for outdoor installations with IP65 level of dust and water protection. We have IP65 type test certification from ERDA Vadodara.

Hulasi offers enclosures and integrated sub systems like PV string disconnector boxes, array / combiner junction boxes AJB, main junction boxes MJB, ACDB, DCDB for photovoltaic PV applications in India.  Details
