Overview of 800V LT Panel

High-Voltage Low Tension Panels for MW-Scale Solar Power Plants

An 800V LT Panel is an advanced low-voltage switchgear assembly rated for 800V AC, designed to support modern high-voltage solar inverter architectures. These panels play a critical role in collecting, protecting, metering, and distributing AC power generated by string inverters before feeding it to step-up transformers or grid interfaces.

AAVAD Instrument Pvt. Ltd. manufactures CPRI-approved 800V LT Panels and Solar ACDB solutions engineered for high reliability, reduced losses, and long-term performance in utility-scale solar power plants.

Why 800V LT Panels Are Important in Modern Solar Plants

With the industry shift towards 1500V DC string inverter systems, AC side voltages have increased to optimize efficiency. 800V AC architectures help solar plants achieve:

• Reduced transmission losses

• Lower cable sizes and wiring complexity

• Fewer DC combiner boxes

• Improved plant availability and uptime

• Lower BOS (Balance of System) costs

Operating at higher AC voltage significantly improves overall system efficiency while maintaining safety and compliance.

What Are 800V LT Panels?

At their core, 800V LT Panels are robust electrical distribution panels that:

• Aggregate AC output from multiple string inverters

• Safely route power to step-up transformers

• Provide fault isolation and protection

• Enable energy metering and SCADA integration

Their higher voltage handling capability makes them ideal for large solar farms and MW-scale renewable projects.
