What these specifications mean

Detailed specifications for onPower NTV - Speicher + Solakon Powertracker IR Deal 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 round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid, communication protocol (CAN or RS485) for talking to the inverter, nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh) and usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50%. 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.

A solar battery stores the energy your panels generate during the day so it can be used after sunset, during a power cut, or whenever grid electricity is most expensive.

Before you buy a battery

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.

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.
Match voltage to the inverter, and confirm the battery appears on the inverter maker's supported list. Closed-loop communication lets the inverter respect the battery's real charge limits instead of guessing.

Where buyers lose money

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.
Sizing the bank for total daily consumption rather than after-dark consumption, which typically doubles the cost for no benefit.

Price and availability

onPower NTV - Speicher + Solakon Powertracker IR Deal is listed at € 979 (EUR). 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 Solakon locally before ordering.

onPower NTV - Speicher + Solakon Powertracker IR Deal — frequently asked questions

How much does onPower NTV - Speicher + Solakon Powertracker IR Deal cost?

onPower NTV - Speicher + Solakon Powertracker IR Deal is listed at € 979 (EUR). 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 onPower NTV - Speicher + Solakon Powertracker IR Deal?

onPower NTV - Speicher + Solakon Powertracker IR Deal is a Solakon product, listed under batteries with model reference SK-ONE-20001. The Solakon brand page lists the rest of its range so you can compare across the catalogue.

Is onPower NTV - Speicher + Solakon Powertracker IR Deal right for my system?

That depends on what it has to connect to. For a battery, check communication protocol (CAN or RS485) for talking to the inverter, nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh) and usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50% against the rest of your equipment before price enters the decision. Leave room to expand. Packs that parallel cleanly let you add capacity later; ones that do not force a full replacement.

Where can I buy onPower NTV - Speicher + Solakon Powertracker IR Deal?

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.
