Sunny Boy Storage
The Sunny Boy Storage 5000W inverter is the interface between the solar panels, the utility grid, and residential energy storage batteries. SMA’s storage inverter operates under an AC-coupled architecture, making it the ideal solution to retrofit existing grid-tie solar PV systems.
The Sunny Boy Storage inverters come standard with a similar feature to the Secure Power Supply found in the US-41 grid-interactive units. During a grid outage, either day or night, the Backup Lite feature provides up to 2000W of power directly from the inverter. For a full home power solution, pair the storage inverter with SMA Automatic Backup Unit and industry-leading high-voltage battery pack.

|Sunny Boy Storage Model||Nominal Power||Backup Overload||Secure Power Supply – Backup Lite|
Automatic Backup Unit
SMA Automatic Backup Unit (ABU) offers an integrated backup power solutions for homeowners. SMA built the ABU with a 200A rated contractor; the contractor automatically disconnects the entire home energy system from the grid during the event of a power outage.
The backup unit comes with two 50A breakers: for the incoming PV power and battery inverter output. The integrated autotransformer balances the power imbalance across phases. It has up to up to 5 kVA capacity; it reduces the potential for system interruption due to imbalanced loads in the household.
The ABU also features a built-in energy consumption metering with pre-installed current transformers as well as a backup controller, which manages and stabilizes the micro-grid. The controller is an essential component; it monitors solar generation, load consumption, and battery state-of-charge.
Secure Power Supply – Backup Lite
The Secure Power Supply (SPS) feature comes standard with the SMA Sunny Boy US-41 series inverters. It is SMA’s battery-less solution for daytime power outages. The SPS can provide up to 2000W to a dedicated outlet wired directly to the Sunny Boy inverter. Backup Lite feature included in the Sunny Boy Storage inverter provide similar benefits during night time.
To benefit from the SPS feature, you need a switch, grounded outlet, box, and conduit to wire (not included with inverter). The SPS output in the US-41 inverters is 2000W; the equipment and wires installed have to be sized to handle the 16 Amps of current the SPS can supply.
Install the SPS during the original solar installation or later on as a retrofit. Please note that the Secure Power Supply feature is not compatible with SMA TS4 module optimizer units.
Sunny Portal Communication
Enhanced communication capabilities remove the need for additional equipment in system monitoring. The connection to SMA Sunny Portal facilitates a superior monitoring solution. It gives you lifetime access to SMA Smart Connected. SMA installation assistant and smartphone commissioning capabilities make getting systems up and running faster and easier than ever before.
For a power backup system fully compliant with NEC 2017 module-level rapid shutdown requirement, have the PV grid connection managed by a Sunny Boy US-41 inverter paired with TS4 modules. The same setup will also provide advanced AFCI compliance to new Standard UL 1699B Ed.1 for arc fault protection. The settings in the inverter can easily be configured to comply with California Rule 21.
