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.
