Product Description
Solar plants need to be up and running. While they are highly susceptible to voltage spikes or surges, our redundant system solutions in the array junction box help them to stay that way.
A String Combiner Box along with Surge Protection Devices (SPDs) installed in the Array Junction Box diverts the excess voltage into the ground through earthing lines and thereby, ensures electrical and electronic equipment protection.

FAQ'S
A PSS/CSS is a factory-built, weather-proof substation that integrates MV switchgear (RMU/VCB), a distribution transformer, and an LV switchboard in one enclosure for fast deployment, smaller footprint, and safer operation.
Typical configurations support 11/22/33 kV primary at 50 Hz with secondary 415 V, and transformer ratings up to about 2.5 MVA; final voltage class, fault duty, and capacity are sized to project requirements.
Segregated MV/Tx/LV compartments, internal-arc-considered design options, IP-rated doors, mechanical/key interlocks, and clear mimic labeling reduce risk, speed isolation, and cut outage time during maintenance or faults.
Systems can include numerical relays, multifunction energy metering, fault passage indication, event logging with time-stamping, and remote monitoring/control via standard industrial protocols for SCADA/PLC.
Ideal for space-constrained urban networks, commercial campuses, metro/rail stations, industrial estates, brownfield capacity upgrades, and renewable evacuation where quick commissioning and compact footprint matter.
