Overview

The SMA Home Storage Solution allows homeowners to unlock the full potential of sustainable energy. Integrating the SMA Home Storage battery makes the modular solution complete: everything from a single source. It perfectly complements SMA‘s hybrid inverters enabling energy solutions of today and tomorrow. Whether during times of low solar irradiation or the highs of midday – the SMA Home Storage can store solar power and make it available as needed. It offers flexible scalability to be adapted to individual needs and has an especially long lifetime of around 8000 charging cycles. With the SMA Home Storage, homeowners are making a conscious choice for quality and additional security with the 10-year warranty. Future-proof electricity storage system Developed for intensive use Ready for future, like dynamic tariffs and virtual power plants (VPP) Integrated black start function for back-up supply (when combined with the SMA hybrid inverter) 8000 life cycles and 10 years of warranty Easy installation, fast commissioning Plug and play solution, including automatic commissioning Preassembled cables for an easy installation Expandable capacity possible within 2 years Unmatched flexibility Compatible with SMA’s hybrid inverters Slim, stackable design that can be scaled from 3.2 kWh to 16.4 kW Wall mounted as standard, or floor standing (with optional base unit) Outdoor installation possible (Protection class IP65)

What these specifications mean

SMA Home Storage Battery is listed with 9 published specifications from SMA, including system battery voltage of HV, nominal storage capacity of 3.28 kWh, height of 483 and width of 610. 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 a battery, the figures that matter most are system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack, continuous charge and discharge current, which limits how much power you can draw from the pack, cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4 and round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid. Storage is what turns a solar array from a daytime bill-reducer into a system that covers evening loads and rides through outages. It is normally the single most expensive component, so sizing it correctly matters more than with any other part.

Choosing a battery: the checks that matter

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

Leave room to expand. Packs that parallel cleanly let you add capacity later; ones that do not force a full replacement.
Compare usable kilowatt-hours, not nameplate capacity. A 100 Ah lead-acid battery at 12 V is nominally 1.2 kWh but only about 0.6 kWh is safely usable, while a 100 Ah LiFePO4 pack gives you roughly 1.0–1.2 kWh.
Size from your evening consumption. Add up what actually runs after sunset for the hours you want covered, then divide by the usable capacity per unit — that number, not the array size, sets how many batteries you need.
Check the continuous discharge rating against your inverter. A battery that stores plenty of energy but can only deliver 50 A cannot support a large inverter at full output.

Where buyers lose money

Mixing old and new batteries, or different chemistries, in one bank. The weakest unit drags the whole bank down and can be damaged by the others.
Sizing the bank for total daily consumption rather than after-dark consumption, which typically doubles the cost for no benefit.
Installing lithium packs in an unventilated, hot enclosure. Sustained high temperature is the fastest way to lose cycle life.

Price and availability

SMA Home Storage Battery is listed at £ 1,413 (GBP). 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 your country: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports SMA locally before ordering.

SMA Home Storage Battery — frequently asked questions

How much does SMA Home Storage Battery cost?

SMA Home Storage Battery is listed at £ 1,413 (GBP). 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 Home Storage Battery?

We hold 9 published specifications for this battery, including system battery voltage HV, nominal storage capacity 3.28 kWh, height 483, width 610 and depth 214.6. The full table is on this page, listed under model HS-BM-3.28-10.

Who makes SMA Home Storage Battery?

SMA Home Storage Battery is a SMA product, listed under batteries with model reference HS-BM-3.28-10. The SMA brand page lists the rest of its range so you can compare across the catalogue.

Is SMA Home Storage Battery right for my system?

That depends on what it has to connect to. For a battery, check usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50%, system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack and continuous charge and discharge current, which limits how much power you can draw from the pack against the rest of your equipment before price enters the decision. Compare usable kilowatt-hours, not nameplate capacity. A 100 Ah lead-acid battery at 12 V is nominally 1.2 kWh but only about 0.6 kWh is safely usable, while a 100 Ah LiFePO4 pack gives you roughly 1.0–1.2 kWh.

Where can I buy SMA Home Storage Battery?

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 — buying in-channel is what keeps the manufacturer's warranty valid.
