Intended Usage
SG1K5TL serial inverters are robust, grid-connected, transformer-less and of high
conversion efficiency.
SG1K5TL inverter transforms the direct current generated by PV arrays into stable
alternating current and outputs the AC power into the utility grid. This inverter is a
crucial unit in the small-scaled PV power system.
If PV arrays need earthing of the positive or negative terminal, they cannot collaborate
with SG1K5TL inverter.
An example about intended usage of the inverter is shown in Fig 2-1.

Any other or additional use is not permitted except the intended use.
The inverter must only be connected to public utility grid. If output of inverter is
connected to local loads (household appliance, lights, motor loads, etc.), the
inverter can not start.
