800V LT Panel

The 800V LT Panel by Wisdom Techno Solutions is a next-generation low-tension AC distribution solution developed to meet the growing demands of high-capacity solar power plants. Designed to operate at 800 V AC, it efficiently aggregates and manages inverter output while significantly reducing transmission losses, cabling requirements, and balance-of-system costs in large-scale renewable energy installations.

A DC Distribution Board is an essential component in solar power installations that consolidates the DC output of various PV strings while providing integrated protection. It is engineered to safeguard expensive inverter systems against direct and indirect lightning strikes, overcurrent, and voltage surges, thereby enhancing system longevity and operational safety.

WTS’ 800V LT Panel (sometimes referred to as an AC Distribution Board: ACDB) consolidates the three-phase and single-phase AC power output from solar inverters into a single, well-protected distribution point. It enhances system reliability by enabling safe power collection, fault isolation, energy metering, and compatibility with remote SCADA monitoring systems — all while handling elevated voltage levels typical in MW-scale solar installations operating with 1500 V DC string inverters.

With the trend toward larger, more efficient solar plants, higher AC voltage capability helps lower transmission losses and reduce the amount of cabling and combiner boxes required, making the system more cost-effective and easier to maintain. Accu-Panels developed its 800 V solution to meet specific EPC and client demands, engineering panels that are not simply retrofitted from 415 V designs but built from first principles for high-voltage applications with robust designs and compliance to international standards.

The 800V LT Panel features a CRCA steel enclosure with robust mechanical support, modular and gasketed gland plates, and superior corrosion-resistant coatings, supporting IP52 protection for indoor applications and up to IP65 for outdoor conditions depending on configuration and accessories. Mounting and design meet ergonomic guidelines so that switches and breakers remain within safe reach.

Inside the panel, key switchgear manages power routing, protection, and metering. The assembly typically includes MCCBs/ACBs with high fault-withstand ratings, surge protection devices, digital metering (with RS-485 outputs for monitoring), protection relays for earth fault and phase unbalance, and provision for SCADA-ready integration. Busbars may be copper or aluminum, sized and insulated for thermal stress and safety compliance, enabling real-time data, fault diagnostics, and remote control capabilities where needed.

Wisdom Techno Solutions’ 800V LT panels are engineered to meet IEC 61439-1 & -2 standards and are CPRI tested and certified for fault withstand, dielectric strength, internal arc protection, and ingress protection levels. Each panel undergoes extensive factory acceptance tests (electrical, mechanical, and functional) as part of quality assurance protocols.

These panels are especially suitable for MW-scale solar parks and large ground-mounted solar installations where high-voltage string inverter outputs are common. Their compatibility with hybrid applications like battery storage systems (BESS), EV charging integration, and grid export systems makes them a versatile choice for next-generation energy infrastructure.

The 800V LT Panel by Wisdom Techno Solutions is a high-voltage low-tension AC distribution solution designed for modern, large-scale solar power plants. Engineered to handle 800 V AC systems, it efficiently collects and distributes inverter output while reducing power losses, cabling requirements, and overall system costs. Built with robust construction, advanced protection, and compliance with IEC standards, the panel ensures safe, reliable, and future-ready power distribution for MW-scale renewable energy applications.
