I am going to install a Photovoltaic system for an orphanage here in Guatemala. There will be 7 inverters with a maximum current of 42A and 240 Volts. The area is quite large with 150 children and 50 adults living on the grounds. The energy used has a minimum current of 65A 24 hours a day. The maximum is 135A mostly between 6PM and 10PM. They have a large generator with an automatic cutoff switch. I would like to connect the inverters on the line side of the inverter between the cut off switch and the meter. I need to find a clean way to connect large cables basically like a tap. The existing connections are bolted on compression lugs. Can someone recommend junction blocks to join together three large compression lugs? I will combine the inverter outputs before the supply side connection. I really don't work with that type of connection much and local suppliers are not much help.
