Do NOT disconnect the PV module from the APsystems Microinverter without first disconnecting the AC power. Be aware that the body of the APsystems Microinverter is the heat sink and can reach a temperature of 80°C. To reduce risk of burns, do not touch the body of the Microinverter.
1.Important Safety Instructions 1.2 Radio Interference Statement EMC Compliance : The APsystems Microinverter can radiate radio frequency energy. If not installed and used in accordance with the instructions, it may cause harmful interference to radio communication. APsystems Microinverter complies with EMC regulations, which are designed to provide reasonable protection against harmful interference in a residential installation.
EMC and is authorized to energize, ground, and tag equipment, systems, and personnel circuits in accordance with established safety procedures. The inverter and complete system may only be commissioned and operated by qualified personnel. APsystems Microinverter DS3D User Manual...

This extreme high DC voltage brings a risk of electrical shocks or electrical arcs which could cause fire in a worst case scenario. When using an APsystems microinverter, each one or two PV modules are connected to DC input. Voltage at the back of each PV module never exceeds...
DS3D is reaching unprecedented power outputs of 2000W to adapt to today’s larger power module. With 2 independent MPPTs, encrypted Zigbee signal, the DS3D benefits from an entirely new architecture. The innovative and compact design make the product lighter while maximizing power production.
4.APsystems Microinverter System Installation A PV system using APsystems Microinverters is simple to install. Each Microinverter easily mounts on the PV racking, directly beneath the PV module(s). Low voltage DC wires connect from the PV module directly to the Microinverter, eliminating the risk of high DC voltage.
It is strictly prohibited to hand carry the microinverter by its AC cable. 4.3.3 Step 3 - Attach the APsystems Microinverters to the Racking a. Mark the location of the microinverter on the rack, with respect to the PV module junction box or any other obstructions.

4.APsystems Microinverter System Installation 4.3.7 Step 7 - Connect APsystems Microinverters to the PV Modules Each channel connects 2 PV modules in series (For PV modules with Voc<60V)..The input channel will not work if connects to a single module(Voc<60V).
4.APsystems Microinverter System Installation 4.3.8 Step 8 - Complete the APsystems installation map a. Each APsystems Microinverter has 2 removable serial number labels. b. Complete installation map by sticking ID label of each microinverter at the right location. c. The second serial number label, could be stuck on the solar module frame, which could help later to confirm the position of the microinverter without dismantling the PV module.
Alternatively, LED sequences could be an indicator of microinverters status (see section 6.1) Once the ECU has been commissioned properly, the APsystems Microinverters will start to send performance data to the ECU. The time required for all of the Microinverters in the system to report to the ECU will vary depending on the number of Microinverters in the system.
APsystems Technical Support. 6.2 ECU_APP APsystems ECU_APP (available in the EMA Manager APP) is the recommended tool to do on-site troubleshooting. When connecting the ECU_APP to the ECU hotspot (please check ECU User Manual for more detailed information), installer can check every microinverter status (production, communication) but also Zigbee signal strength, grid profile and other insightful data helping the troubleshooting.
6.Troubleshooting 6.5 APsystems Technical Support APsystems local Technical Support team is available to support professional installers to get familiar with our products and to troubleshoot installations when needed. Do not attempt to repair APsystems Microinverters. Please contact your local APsystems Technical Support.
7.Replace a microinverter Follow the procedure to replace a failed APsystems Microinverter A. Disconnect the APsystems Microinverter from the PV Module, in the order shown below: 1. Disconnect the AC by turning off the branch circuit breaker. 2. Disconnect the inverter AC connector from the AC Bus.
8.Technical Data ①. Be sure to verify that the voltage and current specifications of your PV module are compatible with the range allowed on APsystems Microinverter. Please check the microinverter datasheet. ②. DC operating voltage range of the PV module must be within allowable input voltage range of the APsystems Microinverter.
Specifications subject to change without notice please ensure you are **Limits may vary. Refer to local requirements to define the number using the most recent update found at web : latam.APsystems.com of microinverters per branch in your area. 2021/11/19 Rev1.0...
