Protection and distribution engineered for every scale of solar
Every solar power plant’s safety and reliability starts with how current is distributed. The ACDB (AC Distribution Box) and DCDB (DC Distribution Box) are the protection devices that control, monitor, and safeguard the flow of current between solar panels, inverters, and the grid – and a poorly built one is one of the most common causes of solar underperformance and compliance failure. Synchro supplies EPC companies and solar developers across India with ACDB/DCDB panels engineered to eliminate that risk, from rooftop installations to utility-scale farms.
Built to Perform
Full protection
guards against current surges, faults, and reverse current from modules, inverters, and the grid
Capacity flexibility
available for 5kW, 10kW, 100kW, and 1MW solar power plants
Quality components
built with high-grade isolators, fuses, and surge protection devices
Ready-to-install
pre-tested and pre-wired for faster commissioning
Custom configurations
engineered for industrial and EPC solar projects specifically, not adapted from stock
Where It Works
From small rooftop installations to utility-scale solar farms, every solar project has a different distribution and protection requirement – and our ACDB/DCDB range covers the full spectrum. Each variant is purpose-built for its application scale, not adapted from a generic design, and every unit is pre-tested and pre-wired before it leaves our facility. Select the configuration that matches your system capacity and installation type, and we will deliver it ready to commission.
Rooftop solar systems (5kW–10kW)
secure, reliable distribution for homes, offices, and small industries
Commercial/industrial plants (50kW–250kW)
dependable power control for factories, warehouses, and institutions
Utility-scale solar farms (500kW–1MW+)
heavy-duty panels built for large grid-connected solar parks
Solar EPC projects
ready-engineered, pre-tested panels for fast, durable installation

What does an ACDB do?
Sends the AC output from the inverter to the grid or load, with built-in overcurrent and surge protection.
What does a DCDB do?
Connects the DC solar string output, manages module fusing, and protects against inverter reverse current.
What capacities are available?
From 5kW rooftop systems to 1MW+ utility-scale installations.
