Chint photovoltaic inverter wiring

Where can I find the Chint power systems user manual?

The manual will be periodically updated or revised due to the product development or improvement. The latest version of this manual can be acquired via the website at 1. IMPORTANT SAFETY INSTRUCTIONS (SAVE THESE INSTRUCTIONS) Please read this user manual carefully before installation of the inverter.

How a PV inverter can be connected with a short circuit?

Ensure that the positive and negative terminals of each PV strings connected to the inverter correctly. The positive or negative terminals of PV strings can’t be connected with short circuit. The total output power of all PV strings can’t exceed the maximum input power of the inverter.

Can a PV inverter be ungrounded?

Uneven distribution of strings among the two MPPTs (e.g. PVIn1:PVIn2 = 3:1) is not recommended and may result in unnecessary power clipping. The inverters operate with ungrounded arrays, although the PV system requires a DC EGC (equipment grounding conductor) to ensure operational safety.

How much does a PV inverter weigh?

The inverters are designed for PV grid-tied systems. The inverters are to be installed with floating or ungrounded PV arrays only. (48.5 pounds). The wire-box portion weighs approximately 6kg (13.2 pounds). inverter and wire-box on the bracket. A team of two is recommended to lift and place the inverter and wire-box into position.

How to install a PV inverter?

After checking the outer packing, move the PV inverter to the designated installation position horizontally. Please place the inverter horizontally on the foam or other soft pads and ensure that the ports are free of load-bearing pressure to avoid inverter damages or scratches.

How does a PV inverter work?

The inverter converts the DC from PV modules to AC with the same frequency and phase as the AC grid. All or part of the AC power is supplied to local loads, and the surplus supplied to the electricity grid.
