Georgetown three-phase inverter installation

How does an extended power & commercial 3 phase inverter work?

The extended power and commercial three phase inverters are provided with an integrated DC Safety Switch and with terminal blocks for the connection of three strings per unit, eliminating the cost of an external DC combiner box.

How many DC inputs does a 3 phase inverter have?

The SE14.4KUS, SE43.2KUS and SE33.3KUS three phase inverters have three pairs of DC inputs and the three phase inverters with synergy technology have three pairs of DC inputs per unit, allowing to connect up to 3 strings per unit without the need for an external combiner box.

Can a 3 phase inverter be installed vertically?

Unused conduit openings and glands should be sealed with appropriate seals. The inverter is typically mounted vertically, and the instructions in this section are applicable for vertical installation. Some three phase inverter models can be installed horizontally (above 10° tilt) as well as vertically, and at any tilt over 10° up to 90°.

How do you ground a 3 phase inverter?

Use only copper conductors rated for a minimum of 90°C/ 194°F. For the SE10KUS, SE20KUS, SE33.3KUS three phase inverters where opposite polarity DC conductors are routed in the same conduit, 1000V rated cables must be used. 1. Insert the grounding cable through the AC drill guide. 2. Connect the cable to the equipment grounding bus-bar.

How long is a 3 phase inverter cable?

The total cable length of the string from the extended power three phase inverter to the farthest power optimizer is 1,150ft (2,300ft from DC+ to DC- of the inverter).

What conductors should be used for a 3 phase inverter?

Use only copper conductors rated for a minimum of 90°C/ 194°F. For the SE10KUS, SE20KUS, SE33.3KUS three phase inverters where opposite polarity DC conductors are routed in the same conduit, 1000V rated cables must be used. This inverter is provided with an IMI (Isolation Monitor Interrupter) for ground fault protection.
