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 CE 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 CE 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 circuits in accordance with established safety procedures. The inverter and complete system may only be commissioned and operated by qualified personnel. APsystems DS3 series Installation Manual...
2.APsystems Microinverter System Introduction 2.1 Key elements of an APsystems system The APsystems Microinverter is used in utility-interactive grid-tied applications, comprised of three key elements: APsystems Microinverter APsystems Energy Communication Unit (ECU) APsystems Energy Monitor and Analysis (EMA) web-based monitoring and analysis system...
When using an APsystems microinverter, PV modules are connected in parallel. Voltage at the back of each PV module never exceeds PV modules Voc, which is lower than 60 Vdc for most of PV modules used with APsystems microinverters. This low voltage is considered “safe to touch” by firemen department and will avoid risk of electrical shock, electrical arcs and fire hazards.
A 24/7 energy access through Apps or web based portal facilitate remote diagnosis and maintenance. The DS3 series is interactive with power grids through a feature referred to as RPC (Reactive Power Control) to better manage photovoltaic power spikes in the grid. With a performance and an efficiency of 97%, a unique integration with 20% less components, APsystems DS3-L and DS3 are a game changer to residential and commercial 3.2 Features of the DS3 microinverter...
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 Figure 9 When plugging in the DC cables, the microinverter should immediately blink red one time and green t en times. This will happen as soon as the DC cables are plugged in and will show that the microinverter is functioning correctly.

Complete installation map by sticking ID label of each microinverter at the right location. The second serial number label, could be stuck on the solar module frame, which could help later to...
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.
Please contact your local 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.
6.0 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.
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 micro-inverter datasheet. ②. DC operating voltage range of the PV module must be within allowable input voltage range of the APsystems Microinverter.
** Limits may vary. Refer to local requirements to define the number of microinverters per branch in your area. *** To be eligible for the warranty, APsystems microinverters need to be monitored via the EMA portal. Please refer to our warranty T&Cs available o n emea.APsystems.com...
