Canadian Solar inverters are used worldwide and feature preset standards for operating on
any grid. Although the grid standard is set at the factory, it is essential the grid standard be
verified for the country of installation before commissioning.
The menu for changing the grid standard or for creating a custom standard is accessible as

of the inverter, inverter damage or the inverter not operating at all.
