Selfio

Haus & Garten

Selfio is a German online-only retailer that sells solar PV kits, battery-storage systems, heat pumps, smart-home energy management hardware and the mounting accessories needed for residential self-consumption projects. Complete plug-and-play sets range from ±€1,500 for a 1 kW balcony unit to ±€15,000 for a 10 kW roof array with 10 kWh battery; most offers sit in the mid-price band, 20-30 % below installer quotations because the kits are pre-engineered and sold without installation labour. The company’s core promise is “do-it-yourself, but not alone”: every kit is pre-sized with matching inverters, cables and mounting rails, shipped on one pallet, and backed by telephone/video planning support, cloud-based design software and a commissioning hotline. Selfio’s best-known lines are the “Balkonkraftwerk” (600–800 W micro-inverter balcony set) and the “Komplett-Solar” 5 kW hybrid package that includes a 5 kWh lithium-iron-phosphate battery and energy-manager gateway, both of which regularly top Amazon.de and Idealo.de solar rankings. Typical buyers are owner-occupant homeowners and technically-minded tenants aged 30-55 who want to cut electricity bills, reduce CO₂ and avoid lengthy installer waits; they value transparency, German-language support and the ability to expand the system modularly. The brand speaks to a frugal, engineering-friendly lifestyle that favours self-reliance, data monitoring and payback periods under eight years. Selfio competes with both conventional solar installers and generalist DIY hardware e-tailers that also list solar components. It differentiates by bundling certified components into code-compliant kits, offering real-time technical support during installation, and providing a single German warranty handler—removing the finger-pointing common when inverter, panel and battery brands differ.

Solar power on your terms, without the installer markup or the wait

Pooltime

Pooltime.de is a German online-only retailer specializing in modular, resin-panel above-ground pools, matching filtration sets, heat pumps, robotic cleaners, and maintenance chemicals. Kits run €2,000–€6,000 (mid-range), while add-ons such as salt-electrolysis units or winter covers stay under €1,000. The entire catalogue is sold factory-direct through the brand’s own webshop; no physical dealers or marketplaces are used. The company’s USP is the “Made in Germany” injection-moulded wall system: 50 mm thick, UV-stable polypropylene panels that clip together without steel braces, cutting install time to one weekend. Every pool ships with a 25-year structural warranty and an online configurator that auto-matches pump and heater output to pool size. Its best-known line, the “Pooltime Edition 120,” is repeatedly cited in German DIY forums for holding its shape on sandy or clay soils without concrete backfill. Buyers are 30-55-year-old suburban homeowners who want a permanent-looking pool but lack the budget or permit rights for in-ground construction. They value German engineering standards, fast DIY assembly, and after-sales phone support in German. Sustainability also matters: the site highlights 100 % recyclable wall panels and A-rated heat pumps, aligning with family-oriented, energy-conscious lifestyles. Pooltime competes with mass-market steel-wall sets sold through big-box chains and with premium composite-panel brands that require dealer installation. It undercuts the latter by 30-40 % while offering thicker walls than the former, positioning itself as the middle ground between throwaway kits and pro-installed systems.

Indevolt

Indevolt’s German webshop focuses on lithium-ion battery upgrades for cordless power tools, e-bikes and garden equipment. Packs are sold either as ready-made replacements (€39-€149) or as DIY cell kits (€19-€89), placing the range in the budget-to-mid segment. Sales are online-only through de.indevolt.com and its Amazon.de storefront; no physical retail network is operated. The brand’s signature offer is higher-capacity “upgrade” batteries that exceed the Ah rating of original DeWalt, Makita, Bosch and Milwaukee packs while fitting the same housings. Every pack is assembled in Poland with Grade-A 18650/21700 cells, shipped with a 24-month warranty and a built-in German-engineered BMS that communicates with the original charger. Best-known lines are the 5.0 Ah → 6.5 Ah slide-on replacements and the 36 V garden-tool “Twin-Power” adapters. Buyers are cost-conscious tradespeople, pro-sumers and e-bike commuters who want OEM-level performance without OEM prices and are comfortable swapping cells themselves. The brand appeals to a repair-over-replace mindset and to DIYers who value transparent cell specs, cycle-life data and fast domestic shipping. Indevolt competes with generic Asian replacement batteries sold on eBay and with premium aftermarket specialists. It differentiates by publishing independent cell-test reports, offering EU-based warranty service within 48 h, and providing German-language how-to videos that reduce installation returns to under 2 %.
