APsystems Microinverter System Introduction 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 AC JUNCTION BOX ECU ENERGY COMMUNICATION UNIT Internet EMA DISTRIBUTION PANEL Figure 1 APsystems DS3 series Installation manual 5 2. APsystems Microinverter System Introduction This integrated system improves safety; maximizes solar energy harvest; increases system reliability, and simplifies solar system design, installation, maintenance, and management. Safety with APsystems Microinverters In a typical string inverter installation, PV modules are connected in series. The voltage adds-up to reach high voltage value (from 600Vdc up to 1000Vdc) at the end of the PV string. This extreme high DC voltage brings a risk of electrical shocks or electrical arcs which could cause fire. 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 60Vdc for most of PV modules used with APsystems microinverters. This low voltage is considered "safe to touch" by fire departments and negates the risk of electrical shock, electrical arcs and fire hazards. APsystems Microinverters maximize PV energy production Each PV module has individual Maximum Peak Power Tracking (MPPT) control, which ensures that the maximum power is produced to the utility grid regardless of the performance of the other PV modules in the array. When PV modules in the array are affected by shade, dust, different orientation, or any situation in which one module underperforms compared with the other units, the APsystems Microinverter ensures top performance from the array by maximizing the performance of each module individually within the array. More reliable than centralized or string inverters The distributed APsystems Microinverter system ensures that no single point of system failure exists across the PV system. APsystems Microinverters are designed to operate at full power at ambient outdoor temperatures of up to 65 deg C (or 149 F). The inverter case is designed for outdoor installation and complies with the IP67 environmental enclosure rating. Simple to install APsystems Microinvertes are compatible with most of 60 and 72 cell PV modules or 120 and 144 half-cut cells PV modules. (In order to confirm compatibility of PV module with APsystems microinverter, feel free to check our online "E-decider" module compatibility tool or contact your local APsystems Technical Support). Installation requires a minimum number of accessories and microinverters offer a lot of versatility to the installer: microinverters can indeed be installed on different roofs with different orientation or with modules having different orientation. In the same way, end-users can extand their system whenever they want with microinverters. Smart system performance monitoring and analysis The APsystems Energy Communication Unit (ECU) is installed by simply plugging it into any wall outlet and providing an Ethernet or Wi-Fi connection to a broadband router or modem. After installing and setting the ECU (see ECU Instruction Manual), the full network of APsystems Microinverters automatically reports to the APsystems Energy Monitor and Analysis (EMA) web server. APsystems DS3 series Installation manual 6 3. APsystems Microinverter DS3 series Introduction APsystems 3rd generation of dual microinverters are reaching unprecedented power outputs of 625VA, 750VA or 880VA to adapt to today's larger power module. With 2 independent MPPT, encrypted ZigBee signals, the DS3-S, DS3-L and DS3 benefit from an entirely new architecture and are fully backwards compatible with the QS1 and YC600 microinverters. The innovative and compact design make the product lighter while maximizing power production. The components are encapsulated with silicone to reduce stress on the electronics, facilitate thermal dissipation, enhance waterproof properties, and ensure maximum reliability of the system via rigorous testing methods including accelerated life testing. 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 photo- voltaic power spikes in the grid. In addition to those excellent features, 97.3% peak efficiency and 20% less components from last generation make APsystems DS3-S, DS3-L and DS3 a game changer to commercial PV. Key Product Feature: One microinverter connects to two modules Max output power reaching 625VA, 750VA or 880VA Two input channels with independent MPPT Reactive Power Control Maximum reliability, IP67 Encrypted ZigBee Communication Safety protection relay integrated Perfectly match 5kW requirement with 8 units APsystems DS3 series Installation manual 7 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).
