Power Limit Setting

Inverter output power can be adjusted via the LCD display or remote grid dispatch from the grid company. The corresponding operating state will display on the LCD screen.

Over-temperature Derating

High ambient temperature, fan broken or poor ventilation will lead to inverter power derating.



When the module temperature exceeds the upper limit, inverter will derate power output until the temperature drops within the permissible range.



When the internal temperature exceeds the upper limit, inverter will derate power output until the temperature drops within the permissible range.

Lower limit of the over-temperature derating: 33% of the nominal powe r.

If the module temperature and internal temperature reach to power derating conditions, inverter will derate the power output according to the lower temperature between the two.

Grid Under-voltage Derating

When grid voltage is low, inverter will derate the output power to make sure the output current is within the permissible range. Once the grid voltage is within Vmin…215V, inverter will derate the output power.

The voltage displayed in the follow figure is the phase voltage.

Before connecting PV array to inverter, the following electrical parameters must be met.

Short-circuit current limit

Considering the negative voltage temperature coefficient of PV cells, more attention should be paid to the open-circuit voltage of PV strings when the ambient temperature is the lowest. Meanwhile please notice that the max. open-circuit voltage of each PV string decreases with the increase of the altitude.

Tak eYL250P-29bPV cells for example.

Open-circuit voltage temperature coefficient (β)

-0.32%/°C

Under the STC condition, where ambient temperature is 25°C, the open-circuit voltage of PV cells is 37.6V×23=864.8V<1100V.

Supposed that the lowest temperature is -25°C, the open-circuit voltage of PV cells is 23×37.6V×[1+β×(min. ambient temperature- STC temperature)] = 23×37.6V×[1+(-0.32%/°C) ×(-25°C-25°C)]=990V<1100V (meet the operation requirement).

Therefore, PV string should be designed to meet the open-circuit voltage requirement even under the lowest ambient temperature condition.

6.4 Grounding the Inverter

Due to the transformer-less design of the inverter, neither the DC positive pole nor the DC negative pole of the PV string can be grounded.

6.4.1 Grounding System Overview

In this PV system, all non-current carrying metal parts and device enclosure should be grounded (such as the PV array frame and inverter enclosure).

When there is only one inverter in the PV system, ground the PE cable.

When there are multiple inverters in the PV system, they can be multi-point grounded. Connect PE cables of all inverters and the mounting metal frames of PV array to the equipotential cable (according to the on-site situation) to realize equipotential connection.

8.1 Disconnecting the Inverter

For maintenance work or any service work, inverter must be switched off. During normal operation, switching off is not necessary.

Proceed as follows to disconnect the inverter from DC and AC power sources

Step 1 Disconnect the external AC circuit breaker and prevent it from accidental

reconnecting.

Step 2 Rotate the DC switch to the “OFF” position and then pull off all the PV string

inputs

Please strictly follow the above sequence. Inverter will not work damage if otherwise.

8.2 Dismantling the Inverter

Refer to Chapter 5 and Chapter 6 to dismantle the inverter in reserve steps.

If the inverter will be reinstalled in the future, please refer to “4.4 Inverter Storage” for a proper conservation.

8.3 Disposal of the Inverter

Users should take the responsibility for the disposal of the inverter.

Some parts and devices in the inverter, such as the LCD display, batteries, modules and other components, may cause environment pollution. Users must comply with the related local regulations to avoid pollution.
