Overview

The SMA Sunny Tripower Smart Energy hybrid inverter with versions from 5.0kW to 10.0kW is ideal for supplying solar power to three-phase properties. Combines smart technology and integrated services to create a space-saving compact system. Users can easily and conveniently generate, use and store solar power. It is possible to make additions to the system at any time, incorporating e-mobility or heat pumps. The integrated battery-backup function safeguards the electricity supply even in the event of a grid failure . That makes PV systems comprehensive, smart energy systems with solar energy self-sufficiency of up to 100 percent. Features: Three-phase / DC-coupled hybrid inverter/charger Integrated battery-backup function Fast charging Compatible with: SMA Home Storage battery BYD HVS & HVM batteries Smart energy management with the Sunny Home Manager Maximum energy yield thanks to SMA ShadeFix Intuitive commissioning via app Quick and easy to install thanks to external terminals Compact design means minimum space requirements Specifications Power: 5.0kW / 6.0kW / 8.0kW / 10.0 kW DC-Voltage (Battery): 150 VDC – 600 VDC Max DC-Current (Battery): 30 A Efficiency (max.): 98.2% Warranty: 5 years / 10 years with registration in Sunny Portal / Sunny Places

Reading the specifications

SMA Sunny Tripower Smart Energy Hybrid Inverters is listed with 14 published specifications from SMA, including power rating of 5000W, MPPT trackers of 2, phases of Three phase and connectivity of Wi-Fi, Ethernet. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.

For an inverter, the figures that matter most are continuous AC output in kW, which caps the load you can run at once, surge or peak rating, which covers the brief inrush of motors and compressors, maximum PV input and the number of MPPT trackers, which set how many panel strings you can connect and the MPPT voltage window, which decides how many panels go in a string. It is the component that decides what a solar system can do: how much power you can draw at once, whether you can export to the grid, whether the system keeps running in a blackout, and how well the panels and battery are managed day to day.

Choosing an inverter: the checks that matter

The checks below apply to any inverter. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Keep the panel array between roughly 1.0 and 1.3 times the inverter's rating. Slight oversizing (a higher DC-to-AC ratio) captures more energy on cloudy mornings and winter days; going far beyond it wastes generation through clipping.
Check the surge rating if you run motors — deep-well pumps, compressors and older air conditioners can draw two to three times their running current for a few seconds at start-up.
Choose a hybrid inverter if a battery is in your plan now or later; retrofitting storage onto a pure grid-tie inverter usually means buying a second unit or an AC-coupled battery system.
Confirm the inverter is approved by your local utility or distribution network before you buy if you intend to export power — grid connection depends on certified anti-islanding and local grid-code compliance, not on the inverter's specifications alone.

What people get wrong

Assuming any grid-tie inverter keeps the lights on during an outage. Standard on-grid units shut down for safety unless they have a dedicated backup or islanding output.
Overlooking the IP rating. An outdoor installation needs at least IP65; indoor-rated units mounted outside fail early.
Buying on peak-watt price alone. A cheap inverter with a narrow MPPT window forces awkward string layouts and can strand a portion of the array.

Price and availability in United Kingdom

SMA Sunny Tripower Smart Energy Hybrid Inverters is listed at £ 1,649 (GBP) for United Kingdom. Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in United Kingdom: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports SMA locally before ordering.

SMA Sunny Tripower Smart Energy Hybrid Inverters — frequently asked questions

How much does SMA Sunny Tripower Smart Energy Hybrid Inverters cost?

SMA Sunny Tripower Smart Energy Hybrid Inverters is listed at £ 1,649 (GBP) for United Kingdom. The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

What are the specifications of SMA Sunny Tripower Smart Energy Hybrid Inverters?

We hold 14 published specifications for this inverter, including power rating 5000W, MPPT trackers 2, phases Three phase, connectivity Wi-Fi, Ethernet and height 598. The full table is on this page, listed under model STP-5.0-3SE-40.

Who makes SMA Sunny Tripower Smart Energy Hybrid Inverters?

SMA Sunny Tripower Smart Energy Hybrid Inverters is a SMA product, listed under inverters with model reference STP-5.0-3SE-40. The SMA brand page lists the rest of its range so you can compare across the catalogue.

Is SMA Sunny Tripower Smart Energy Hybrid Inverters right for my system?

That depends on what it has to connect to. For an inverter, check maximum PV input and the number of MPPT trackers, which set how many panel strings you can connect, the MPPT voltage window, which decides how many panels go in a string and peak and weighted (European/CEC) efficiency, typically 96–98.5% against the rest of your equipment before price enters the decision. Check the surge rating if you run motors — deep-well pumps, compressors and older air conditioners can draw two to three times their running current for a few seconds at start-up.

Where can I buy SMA Sunny Tripower Smart Energy Hybrid Inverters in United Kingdom?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer in United Kingdom — buying in-channel is what keeps the manufacturer's warranty valid.
