Solakon ONE Erweiterungsspeicher B2B

€ 569EUR · price may vary

Model: SK-23009
Specifications: 0

Overview

Der Solakon ONE Erweiterungsspeicher erhöht die Kapazität Ihres Basismoduls um zusätzliche 2,11 kWh und lässt sich problemlos in das bestehende System integrieren; ideal, um den Speicher flexibel auf bis zu 12,66 kWh auszubauen und mehr Solarstrom effizient zu nutzen – ganz ohne zusätzlichen Installationsaufwand.

Reading the specifications

Detailed specifications for Solakon ONE Erweiterungsspeicher B2B have not been published yet. Solakon lists this battery in the Batteries, and we add fields as the manufacturer releases them — in the meantime, ask your distributor for the datasheet before ordering.

For a battery, the figures that matter most are cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4, round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid, communication protocol (CAN or RS485) for talking to the inverter and nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh). 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

Installing lithium packs in an unventilated, hot enclosure. Sustained high temperature is the fastest way to lose cycle life.
Ignoring the charge current limit and pairing a large array with a small bank, which trips protection and shortens life.
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.

Price and availability in Germany

Solakon ONE Erweiterungsspeicher B2B is listed at € 569 (EUR) for Germany. 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 Germany: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Solakon locally before ordering.

Solakon ONE Erweiterungsspeicher B2B — frequently asked questions

How much does Solakon ONE Erweiterungsspeicher B2B cost?

Solakon ONE Erweiterungsspeicher B2B is listed at € 569 (EUR) for Germany. 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.

Who makes Solakon ONE Erweiterungsspeicher B2B?

Solakon ONE Erweiterungsspeicher B2B is a Solakon product, listed under batteries with model reference SK-23009. The Solakon brand page lists the rest of its range so you can compare across the catalogue.

Is Solakon ONE Erweiterungsspeicher B2B right for my system?

That depends on what it has to connect to. For a battery, check 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 and cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4 against the rest of your equipment before price enters the decision. Read the warranty in full: lithium warranties are stated as a term plus either a cycle count or a total energy throughput, and whichever limit arrives first ends the cover.

Where can I buy Solakon ONE Erweiterungsspeicher B2B in Germany?

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