Need for AC earth pits in solar installations?

We do not need to install new AC earth pits for solar projects since the existing AC earth pits would suffice (if they have been designed properly to handle the fault current). In a solar installation, we are not increasing the overall AC current in the AC circuit. Before solar, if 10A was flowing [...]

Can DC, AC and LA earth pits be connected together?

Technically Yes. All earthing pits should be bonded together so that there is equipotential bonding amongst them thus preventing back-feed from earth. However, some DISCOMs insist that DC earthing pits, AC earthing pits and LA pits should be kept separate. Please have a read of Legrand's Protection against Lightning Effects guide (Page 8) which [...]

With highly sensitive electrical and electronic components in solar installations, the need for protection of these costly equipment against fault and lightning current is very much necessary. Electrostatic discharge can damage sensitive electronic equipment and disturb the solar power supply. Any voltage difference between individual electronic units can destroy valuable equipment. In addition, noise [...]
