What is the SMA collection and what does it offer?
SMA is a benchmark in power electronics for photovoltaics. In this collection you will find grid-tied inverters (Sunny Boy and Sunny Tripower), storage solutions (Sunny Boy Storage / Tripower Storage), and equipment for off-grid and battery systems (Sunny Island), as well as meters, surge protection devices, communication modules, and electric vehicle chargers. The goal: a reliable, efficient, and easy-to-operate solar system, from residential to small business applications.
Advantages and limitations
- Efficiency and reliability in single-phase and three-phase ranges, with a wide PV operating range and 1–10 MPPT depending on power.
- Comprehensive ecosystem: meters, data manager, SPD, gateways, and EV chargers to complete the installation.
- Storage and backup options with compatible batteries (AC coupled or DC depending on the family).
- Scalability to grow in power, batteries, or smart consumption points.
- Limitations: check exact battery/communication compatibility, number of available MPPT, and admissible short-circuit power.
Applications
- Single-phase residential self-consumption with single-phase inverters and feed-in control.
- Light commercial/industrial three-phase with three-phase inverters with multiple MPPT.
- Systems with batteries for backup/energy savings (AC or DC coupling depending on the range).
- Integration with electric vehicle chargers and advanced management.
How to choose your SMA solution
- Topology: pure grid connection (without battery), hybrid with battery, or AC storage (coupled on the AC side).
- Power and MPPT: align AC kW and number of MPPT with orientation/strings and load peaks.
- Battery compatibility: confirm voltage (48 V/HV) and communication protocol for backup/peak shaving.
- Energy management: add meter/manager for zero feed-in, balancing, and remote monitoring.
- Protections: size SPD and MCBs/RCBOs in AC and DC.
Indicative specifications (depending on family)
| Grid ranges | Sunny Boy (single-phase) • Sunny Tripower (three-phase) with 1–10 MPPT depending on power |
| Hybrids / storage | Sunny Boy/Tripower Storage (AC/DC, depending on model) • Integration with compatible batteries |
| Systems with 48 V batteries | Sunny Island for microgrid/off-grid and backup |
| Management and measurement | Energy meters, data manager, RS485/Ethernet/Wi-Fi interfaces |

| Electric mobility | Domestic and business EV chargers (depending on model) |
Check the datasheet for each reference for PV voltages, input currents, MPPT, AC power, battery compatibility, and included accessories.
Best practices
- Size strings by voltage/current in cold/hot conditions and distribute by MPPT to reduce losses.
- Implement SPD in DC and AC and selectivity in protections for service continuity.
- In systems with batteries, define critical loads and the mode of operation (backup, self-consumption, peak shaving).
- Enable monitoring and updates to maintain performance and installation records.
Quick comparisons
- Sunny Boy (single-phase) vs Sunny Tripower (three-phase): choose based on available grid and load distribution.
- Storage AC vs hybrid DC: AC facilitates retrofit; DC optimizes efficiency in new installations.
