800V LT Panel

Accu-panels has introduced a selection of LT Panels (ACDB) with 800V AC ratings to support the higher voltage architectures in solar power plants. 800V AC ACDB solutions will help new solar power plants introducing string inverter architectures to lower overall system costs. Operating with higher voltages reduces the transmission losses & cabling costs of solar plants, while limiting the impact of any faults, reducing downtime and maximizing productivity. Higher voltage ratings will also mean fewer DC combiner boxes and less wiring complexity.

Solar ACDB (Ac distribution board) is a crucial a part of the SPV system for solar energy Plant. Accu-panels is CPRI approved #acdb #dcdb manufacturer in India.

It combines the output 3 phase as well as single-phase AC power of inverter placed in the solar plant system into a single box called ACDB (AC Distribution Board).We are making customized boards consistent with client’s specifications, like indoor type (IP52), outdoor type floor standing, wall mounting, stand mounting consistent with the client requirement. Also, we offer IP67 Certificate for Polycarbonate box and IP65 certificate for MS box

Why We have Start 800V LT Panel Manufacturing?

Accu-Panels has been manufacturing All type of LT panels and Solar ACDB DCDB since 2009. We have made and supply a lot of electrical panels. Solar is our favorite sector in Industries. One day we received an inquiry from EPC contractor with a requirement of 800 volts. We have Offer normally with 415V but after Order So many challenges we have faced at the time of Designing. We have developed a very well-designed team. Our team made a good design after many discussions with client, Consultant & Developer. Finally, A design ready and switchgear manufacturer have also approved it. Even though the manufacturing time of 800V Switchgear was long, we requested a lot and delivered it as soon as possible. In addition, the design was IP65 (Outdoor Application). So that we had enough Ventilation space in the panel. Although we are CPRI Approved and we undertook panel manufacturing by follow IEC 61439 as per requirements of Standards. Thus, giving warning to EPC contractor while charging for check temperature daily for avoid heating issue. Even though we have found some heating issue in CT and PT. After which we got to know a lot and, in our quality, we brought a lot of improvement and finally we made a design that is MW scale LT panel by brand “ACCU-PANELS”.

What Are 800V LT Panels?

At their core, 800V LT panels are low-voltage switchgear assemblies rated for 800V AC. These powerful yet compact units play a crucial role in modern solar farms by:

Aggregating output from multiple string inverters

Safely routing power to step-up transformers

Managing faults and enabling remote SCADA monitoring

Their elevated voltage handling capacity makes them uniquely suited for today’s high-performance inverter systems, transforming traditional energy distribution into smart, scalable infrastructure.

 Why They Matter in MW-Scale Solar Projects

As developers and EPCs (Engineering, Procurement & Construction companies) aim for reliability and long-term ROI, these panels emerge as a key enabler. The shift toward 1500V DC string inverter systems introduces new voltage demands on AC infrastructure—and 800V LT panels meet the challenge with:

Superior electrical compatibility
Robust fault isolation and energy metering capabilities
Built-in compliance with international standards (CPRI & IEC 61439)

This ensures safe, continuous operation while supporting large-scale deployments across diverse geographic conditions.
