7 Section 1: Introduction About Pika Islanding Inverters: X7601/X7602/X11402 Islanding Inverters connect to the Pika PV Link optimizers to form the Pika Energy Island system for grid-tie solar-plus-storage. Upon the loss of grid power, Islanding Inverters disconnect from the grid and provides AC power to support critical loads. The inverter provides islanding power without an external autotransformer. High voltage smart-batteries connect to Islanding Inverters with no additional storage interface. All Pika Energy products use the REbus 380VDC nanogrid to connect energy sources, storage, loads and the grid. The REbus nanogrid automates the flow of power to enable plug-and-play setup and operation of Pika Energy equipment. For more information about REbus, visit pikaenergy.com. In the diagram below, an X7601 is directly connected to PV Link optimizers and high voltage lithium ion storage on the DC (REbus) line, shown the the left of the inverter. To the right of the inverter are AC lines: 240VAC for grid and home loads, and critical load support up to 50A. Solar Battery Inverter Grid Loads Fig 1.

9 Section 2: Safety Specifications Safety Shutdown The Pika Energy Island system can signal to connected devices on REbus to shut down and limit output voltage to a safe level. The red Safety Shutdown button on the front of X7601/X7602/X11402 activates a Safety Shutdown. An external shutdown button may also be installed, given appropriate labeling. See External Safety Shutdown Switch on page 27 of X7601/X7602/X11402 Installation Manual. To enter a Safety Shutdown, press and hold the red button on the front of the inverter. The Safety Shutdown LED will illuminate and the LCD screen will indicate a Safety Shutdown has been initiated. In a system configured to provide backup power, the DC bus will remain energized on loss of AC grid power. Upon entering a Safety Shutdown, a shutdown signal will be transmitted to all devices connected to REbus. In Safety Shutdown, X7601/X7602/X11402 will disconnect from the grid, stop sourcing power to REbus, and immediately disable all sources on REbus by sending a global shutdown signal. All PV Link optimizers will disconnect their output. The Safety Shutdown LED will be illuminated to show that the inverter has entered a Safety Shutdown. DC bus voltage will be displayed on the inverter screen. WARNING: UNLESS THE SYSTEM IS IN A SAFETY SHUTDOWN, LIVE VOLTAGE MAY BE PRESENT, EVEN WHEN THE POWER GRID HAS FAILED AND THERE IS NO SOURCE OF POWER FROM THE SOLAR PANELS. TO ENSURE THE DC BUS IS NOT POWERED, ALWAYS ACTIVATE SAFETY SHUTDOWN BEFORE PERFORMING EMERGENCY OR SERVICE WORK. X7601/X7602/X11402 Operation Manual M

10 Grid Connect Section 3: Operational Modes Overview Note: Some operational modes require current transformers to be installed with the Pika Energy Island. Current Transformers on page 26 of Installation Manual for more information.. Islanding Inverters have several operational modes available for various installation configurations, markets, and applications. X7601/X7602/X11402 prioritizes the distribution of power differently based on the selected operational mode. For information on how to configure a Pika Energy Island installation for each Operational Mode, see System Configurations on page 35 of X7601/X7602/X11402 Installation Manual. Use this chart to select the correct operational mode for X7601/X7602/X Priority Priority Backup Clean Backup Self Supply Grid Connect 1 Charge batteries from bus Charge batteries from bus Support local loads Support local loads 2 Charge batteries Support local Charge batteries Export to grid from grid loads from bus 3 Support local Export to grid Export to grid - loads 4 Export to grid Grid Connect In Grid Connect mode, X7601/X7602/X11402 functions as a conventional grid-tied inverter system. Powering local loads will be prioritized, and when generation exceeds load demand, excess power is exported to the utility for net metering and other credits. Current transformers are optional for this mode. Without current transformers, you will only see the DC power flowing between your solar array, battery (if installed) and loads. Backup power functions are not employed in Grid Connect mode. If the grid is unavailable, the inverter will disconnect and cease exporting power. Batteries are not required for Grid Connect Mode. For applications in which batteries will be connected to the Pika Energy Island at a later date, operate in Grid Connect mode until batteries are installed. 10 X7601/X7602/X11402 Operation Manual M

11 Section 3: Operational Modes Overview Self Supply In Self Supply mode, X7601/X7602/X11402 prioritizes powering local loads using solar and/or stored power first. Current transformers are required for this mode. In this mode, generated solar power will be used to recharge batteries before any power is exported to the grid. This mode is optimal in markets in which net metering is unavailable or unfavorable, making battery-stored power economically more attractive than grid-provided power. Fig. 2.1 Fig. 2.2 Fig. 2.3 If more power is being produced by the solar array than is needed by local loads, X7601/X7602/X11402 will store energy in the battery for later use [Fig. 2.1]. If the battery is full and a surplus of power is available, that surplus is exported to the grid [Fig. 2.2]. When local demand exceeds available solar-generated power (e.g. at night), the battery supplies power to support local loads. [Fig. 2.3] If the battery is depleted and no solar power is available, power is drawn from the grid to power loads as a last-priority source. Clean Backup In Clean Backup mode, Islanding Inverters prioritize keeping batteries charged and ready for grid interruption, using only solar power. Current transformers are optional for this mode. If the battery is not fully charged, X7601/X7602/X11402 will use all available solar power to charge the battery, with the goal of filling the battery before a grid failure. Grid power will not be used to charge batteries in this mode. Fig. 3.1 Fig. 3.2 Fig. 3.3 X7601/X7602/X11402 Operation Manual M

12 Priority Backup When the batteries are full, excess solar power will support local loads. If needed, the grid will provide power to satisfy additional local load demand [Fig. 3.1]. When the battery is fully charged, powering local loads will be prioritized before exporting power to the grid [Fig. 3.2]. When grid service is interrupted, the system will automatically begin islanding, powering local loads with solar power or battery-stored power [Fig. 3.3]. Priority Backup In Priority Backup mode, Islanding Inverters prioritize keeping batteries charged and ready for grid interruption, using solar power or grid power. Charging using renewable power is prioritized. Current transformers are optional for this mode. If the battery is not fully charged, all available solar power will be used to charge the battery, with the goal of filling the battery before a grid failure. If available solar power does not meet bus voltage requirements for recharging the battery, the grid will provide power to expedite battery recharging. Fig. 4.1 Fig. 4.2 Fig. 4.3 If solar and grid power are available, both can be used to charge the battery. With current transformers installed, the system will display the amount of power being drawn from the grid and how much is being consumed by local loads before reaching the battery [Fig. 4.1]. Without current transformers, only DC power being used to charge batteries through the inverter [Fig. 4.2] will be displayed. In the event of a grid failure, the inverter will island. Critical loads and battery charging will be supported by available solar power [Fig. 4.3]. If available solar power is insufficient, critical loads will be supported by battery power. Zero Export In some markets, solar PV systems are prohibited from back-feeding the AC grid at all. For these applications, use Zero Export mode. This is a subset of Self Supply mode. The key difference is 12 X7601/X7602/X11402 Operation Manual M

13 Section 3: Operational Modes Overview that in Zero Export mode, when the batteries are full and there are no loads, rather than sending excess power to the grid, the Pika Energy Island will limit power generation such that it matches the power consumed by local loads resulting in no exported power. Current transformers are required for this mode. Selecting an Operational Mode Which X7601/X7602/X11402 Operational Mode is Best for My Needs? Goal Keep batteries charged as much as possible Keep batteries charged using only solar power Sell to the grid as much as possible Use grid as little as possible Never sell power to the grid* Optimal Inverter Mode Priority Backup Clean Backup Grid Connect Self Supply Zero Export * Required in select markets.

Press the center button to view available options such as Enable, Disable, or Mod. Settings. Enabling and Disabling Devices The Pika Energy Island system is able to operate independently without input from a user. The inverter and other parts of the system are able to return to operation automatically, even after events such as power outages. To ensure this behavior is safe and predictable, all REbus devices must be Enabled by the user before they will operate. Enabling the device gives it permission to resume operation on power-up. If a device is Disabled, it will stay in a Disabled state, and will not resume operation until it receives user input. Once Enabled, if grid power is present the X7601/X7602/X11402 will create a DC voltage, establishing the REbus nanogrid. Devices connected to REbus will wake up and begin communications. Each connected device must be Enabled before allowing it to operate. Once Enabled, connected devices will automatically resume operation whenever a REbus DC nanogrid is established. If a device has never been enabled, it will stay in a Disabled state until it is enabled by a user. WARNING: Never Enable any device during an installation or while there are exposed wires present. Always be sure to initiate a safety shutdown and disconnect power sources when performing service. X7601/X7602/X11402 Operation Manual M

Intended (normal) Use Your inverter is strictly constructed according to approved safety requirements. Improper use may lead to lethal hazards for operators and/or damage to devices and property. X7601/X7602/X11402 is certified to comply with the UL 1741 standard for utility-interactive devices, and includes important safety features. The anti-islanding safety feature shuts down the inverter in the event of a grid power failure to avoid backfeeding power during a grid outage, which could result in injury to utility repair personnel. Improper use or modification of the X7601/X7602/X11402 may result in serious property damage, personal injury or death. REBUS INPUT ONLY! X7601/X7602/X11402 is designed to accept regulated direct current (DC) from REbus compatible devices (e.g. Pika PV Link S2501, REbus-compatible wind turbines) into grid-compatible alternating current (AC). DO NOT CONNECT PHOTOVOLTAIC MODULES DIRECTLY TO THE REBUS INPUTS OF THE X7601/X7602/X11402 INVERTER. DOING SO WILL VOID THE WARRANTY AND MAY DAMAGE THE INVERTER. Any use other than the specified intended use shall not be deemed intended or normal use, and may result in property damage, personal injury or death. Pika is not liable for damage or injuries caused by unintended use. Damage caused by unintended use is at the sole risk of the operator. Intended use shall also include adherence to the operating and installation instructions. A trained and authorized installer must obtain all necessary permits and agreements from the system owner s local government and utility company for a legal and code-compliant installation of Pika Energy systems.
