Description
The Aavad Instrument 800V LT Panel (ACDB) represents a major technical step forward for high-capacity solar power generation. Engineered specifically for 800V AC, 50Hz, 3-wire electrical networks, this panel acts as a centralized collection point for AC power generated by modern 1500V DC string inverter architectures. By transitioning from traditional 415V networks to an 800V system, solar EPC developers significantly reduce transmission line losses and cut overall cabling expenditure.

FAQs
1. Why are Solar Power Plants transitioning from 415V to 800V LT Panels?
Moving from 415V AC to 800V AC allows a solar plant to transmit the same power at a lower current. Since resistive cable losses are proportional to I²R, reducing current can significantly reduce electrical losses in AC feeders. Higher-voltage LT distribution can also help optimize AC cable sizing, voltage drop, Balance of System (BOS) costs, and overall solar plant electrical infrastructure, depending on the plant architecture.
2. Are Aavad Instrument 800V LT Panels certified for International Compliance?
Aavad Instrument 800V LT Panels are engineered for high-voltage solar AC distribution applications and can be manufactured in accordance with IEC 61439 requirements for low-voltage switchgear and controlgear assemblies. Where applicable, CPRI-tested or approved configurations can be supplied according to the project specification and selected panel design.
3. Can these Panels be deployed in Extreme Outdoor Environments?
Yes. Outdoor configurations can be supplied with protection ratings of up to IP65 and enhanced corrosion protection. A C5-grade anti-corrosive coating system can be achieved through a multi-stage chemical pretreatment process, helping protect the enclosure against rain, humidity, dust, UV exposure, and corrosive outdoor environments commonly encountered in utility-scale solar installations.
4. What is the maximum Operator Switch Height on these Panels?
The panel design maintains an overall structure height of ≤2400 mm, while the highest frequently operated switch or control device is positioned at approximately ≤1750 mm from finished floor level. This arrangement supports improved operator accessibility, ergonomic operation, inspection, and maintenance safety in accordance with the applicable project and safety requirements.
