Plug and Play Solar System
Practical guide to home solar — with a portable power station
No roof mount, no permit, no seven-figure gamble. If you're technically inclined, don't trust the marketing specs, and want to move step by step: here are the real numbers and limits — without the hype.
The manufacturer's datasheet and reality aren't the same. A "1000 W solar input" with your specific panel might only deliver 590 W — nobody explains that anywhere.

More numbers and realistic examples
If you want to know how to calculate cold Voc, or why the 400 W label isn't enough: registration brings new materials and calculators.
The panel label says 400 W. Your device's MPPT window decides whether this panel can be connected safely — and how many go in series.
The datasheet shows three numbers: watt, ampere, voltage. Two won't cause trouble. The third will — and faster in cold weather.
Guide
You don't need the biggest power station and four panels at once. Phasing works because you measure — and don't buy what your device can't safely accept.
No roof, no permit, no million-forint investment — but what does a 250 Wh–3 kWh system realistically deliver in Central Europe?
Selection
The label says 1800 W AC and "1000 W solar" — but for the solar input, the voltage window and A/port decide. Filter like this.

Planning
On the DC side, voltage drop and heating matter. MC4, polarity, length — undersized cable causes silent failure.
More panel watts than max solar input — on purpose. Summer clipping, but winter and cloudy weather is where the benefit lies.
Series: voltage rises, current does not. Parallel: current rises, voltage stays the same. Wrong choice = clipping or overvoltage.

Installation
Extension-cord use and ground-mounted panel: one category. Fixed wiring, earthing, RCCB: from there it's a different game — and not DIY.
The most common mistakes are not "wrong screw" — but wrong voltage calculation, marketing W, and undersized DC cable.
In this category, a ground mount is often better than the roof. Orientation, tilt, wind load, and shade-free placement — that's where daily Wh is decided.
Calculators
Not price, not affiliate links — PV input range, A/port, port count, connector, idle consumption. Comparison by numbers.
Distance, Imp, Vmp → mm² and % drop. Why voltage matters more than the "thick cable" intuition.
Panel Voc/Vmp/Imp + device MPPT window and A/port → series/parallel, cold Voc, margin. The interactive tool is in development.
