Product Overview 2.1 Product Introduction Function The SUN2000L is a single-phase grid-tied PV string inverter that converts the DC power generated by PV strings into AC power and feeds the electricity into the power grid. Models This document involves the following product models: ...
Surge protection is supported on both the DC and AC sides. The SUN2000L has a reserved battery port to connect to batteries, which are used to store the surplus power produced by PV strings and not required by residential loads. The power stored in batteries can be exported to the power grid based on the load condition to meet peak and valley power consumption requirements and maximize the benefits.
Page 24
Operating In Operating mode: The SUN2000L converts DC power from PV strings into AC power and feeds the energy to the power grid. The SUN2000L tracks the maximum power point to maximize the PV string output.
Keep the storage temperature at –40° C to +70° C and the humidity at 5%–95% RH. The SUN2000L should be stored in a clean and dry place and be protected from dust and water vapor corrosion. A maximum of 10 SUN2000Ls can be stacked. To avoid personal injury or device damage, stack SUN2000Ls with caution to prevent them from falling over.
Before unpacking the SUN2000L, check the outer packing materials for damage, such as holes and cracks, and check the SUN2000L model. If any damage is found or the SUN2000L model is not what you requested, do not unpack the product and contact your supplier as soon as possible.
The SUN2000L is protected to IP65 and can be installed indoors or outdoors. Do not install the SUN2000L in a place where a person can easily touch it because its enclosure and heat sinks are extremely hot during operation.

The SUN2000L must be installed in a well-ventilated environment to ensure good heat dissipation. When installed under direct sunlight, the power of the SUN2000L may be derated due to additional temperature rise. Install the SUN2000L in a sheltered place or install an awning over the SUN2000L.
SUN2000L-(2KTL-5KTL) User Manual 4 System Installation Installation Clearance Requirements Reserve enough clearance around the SUN2000L to ensure sufficient space for installation and heat dissipation. Figure 4-2 Installation clearance requirements 4.4 Installing the Mounting Bracket Fixing holes can be used in three combinations. Select a hole combination based on site requirements.
Page 32
4 System Installation Avoid drilling holes in the utility pipes and/or cables attached to back of the wall. If the length or number of M8x80 expansion bolts supplied with the SUN2000L is not enough, prepare M8 stainless steel expansion anchor bolts.

5 Electrical Connections The SUN2000L is embedded with a residual current monitoring unit (RCMU). Only a single-phase circuit breaker or a similar AC load breaking device is required to function as the external AC switch (shown by G in...
5.3 Installing the AC Output Power Cable Prerequisites An AC switch must be installed on the AC side of the SUN2000L to ensure that the SUN2000L can be safely disconnected from the power grid. Do not connect any load between the SUN2000L and the AC switch.
Page 47
User Manual 5 Electrical Connections According to IEC62109, to ensure the safe operation of the SUN2000L in the case of PE cable damage or disconnection, connect the SUN2000L PE cable according to the requirements described 5.2 Installing the PE Cable and ensure that the SUN2000L PE cable meets at least one of the following requirements before disabling the grounding detection function.
Before connecting the DC input power cable, ensure that the DC voltage is within the safe range (lower than 60 V DC) and that the DC switch on the SUN2000L is OFF. Failing to do so may result in electric shocks.
Page 51
During the installation of PV strings and SUN2000L, the positive or negative terminals of PV strings may be grounded if power cables are not properly installed or routed. In this case, an AC or DC short circuit may occur and damage the SUN2000L. This damage is not covered under any warranty.
Page 54
Figure 5-14 Observing core wires through the hole on the terminal Step 2 Ensure that the DC input voltage of each PV string is within the specified range of the SUN2000L using a multimeter and check that the polarities of DC input power cables are correct.
Page 55
Follow-up Procedure Before removing the positive and negative connectors, ensure that the DC switch is OFF. To remove the positive and negative connectors from the SUN2000L, insert an open-end wrench into the notch and press the wrench with an appropriate force.
If no battery connects to the SUN2000L, do not remove the watertight cap from the battery terminal. Otherwise, the SUN2000L will not comply with its Ingress Protection Rating. If a battery connects to the SUN2000L, set aside the watertight cap. Reinstall the watertight cap immediately after removing the connector.

In this case, an AC or DC short circuit may occur and damage the SUN2000L. This damage is not covered under any warranty or service agreement.

Residual Current Sensor alarm. The ALARM port reserves an RS485/12 V signal port. The alarm beacon should be installed within 2 meters away from the SUN2000L. The shield layer of the device signal cable connected to the ALARM port and the COM port is also advised to be grounded.
Grounding securely, and reliably. Switch status The DC switch and all the switches connecting to the SUN2000L are OFF. The AC output power cable, DC input power Cable connections cable, battery cable, and signal cable are connected correctly, securely, and reliably.
AC voltage on the power grid side of the AC switch is within the specified range. If the DC is on and the AC is off, the SUN2000L reports a Grid Loss alarm. The SUN2000L starts normally only after the fault is rectified.
Step 3 Turn off the DC switch at the bottom of the SUN2000L. Step 4 Turn off the DC switch between the PV string and the SUN2000L if there is any. Step 5 If a battery connects to the battery port, turn off the battery switch.
System Maintenance 7.1 Routine Maintenance To ensure that the SUN2000L can operate properly in the long term, you are advised to perform routine maintenance on it as described in this chapter. Before cleaning the system, connecting cables, and maintaining the grounding reliability, power off the system (see 6.4 Powering Off the System...
