1100 V indicates the maximum DC withstanding voltage of the inverter. The inverter is not damaged within the voltage range. The SUN2000-3-10KTL-M1 has a maximum DC withstanding voltage of 1100 V, a maximum operating voltage of 140–980 V, and a startup voltage of 200 V. The SUN2000-12-20KTL-M2 has a maximum DC withstanding voltage of 1080 V, a maximum operating voltage of 160–950 V, and a startup voltage of 200 V.
No. The -M0 series does not support Smart PV Optimizers. The subsequent -M1 and -M2 series support Smart PV Optimizers.
Yes. This function is enabled by default. (You can disable it using the local commissioning tool in the FusionSolar app by choosing Parameter configuration > Feature parameters.)
The expansion bolts delivered with the inverter are mainly used for solid concrete walls. For other types of walls, prepare bolts by yourself and ensure that the wall meets the load bearing requirements of the inverter.
No. The SUN2000-3-10KTL-M1 and SUN2000-12-20KTL-M2 can only be connected to the FusionSolar Smart PV Management System.
When the SmartLogger 3000A is used, connect the communications cable of the Smart Power Sensor to the SmartLogger COM port. When a single inverter is used, connect the cable to the RS485-2 port on the inverter.
No. If multiple inverters are cascaded, only one primary controller can be configured in the system. You can connect either the Smart Dongle or the SmartLogger 3000A to the system. (In China, export limitation is not required. This solution supports cascading the Smart Dongle with multiple inverters. For solutions used outside China, the Smart Dongle is connected to a single inverter. The SmartLogger 3000A is required when multiple inverters are cascaded.)
On the FusionSolar WebUI, choose Setting > User Management to add an account. Select installer and select the company for account management. You can use the account to manage all the PV plants of the company.
The SUN2000-12-20KTL-M2 supports two MPPTs. It is recommended that the number of PV modules connected to different PV strings controlled by the same MPPT be the same. Otherwise, parallel mismatch may occur, resulting in energy yield loss.
In this case, the export limitation function is implemented by the SmartLogger 3000A. You only need to set the SmartLogger.
No. For better collaboration between the Smart Power Sensor and Huawei inverters as well as for better system performance, only Huawei DTSU666-H Smart Power Sensor is supported.
The installer account needs to be created by the upper-level distributor.
