Solar Inverter Oversizing: DC/AC Ratio and Clipping Loss
Wired White v2 Compare solar DC/AC ratios, annual yield and added-panel payback. Separate MPPT current loss, inverter clipping and grid export curtailment, with an east–west option.
Rechner zur Auslegung von Solarwasserpumpen und Bohrbrunnen
Wired White v3 Legen Sie eine Solarpumpe anhand des Tagesbedarfs, der Brunnenabsenkung und der Rohrleitungsverluste aus. Schätzen Sie die PV-Leistung in kWp, die Pumpenwellenleistung in hp, den stündlichen Förderstrom und die Wasserüberdeckung am Pumpeneinlauf ab.
PV String Sizing Calculator for Cold Mornings
Wired White v2 Check cold-morning PV string voltage against the inverter’s hard DC limit, hot MPPT voltage, current and DC/AC ratio. Animate a temperature-dependent I–V curve.
PV Single-Diode Model: Datasheet I-V Curves and MPPT
Wired White v3 Build a PV module I-V and P-V curve family from datasheet points. Scale a matched array and animate P&O or incremental conductance MPPT with voltage-step and sampling trade-offs.
Power Station Size Calculator: Runtime, Surge and Solar Recharge
Wired White v2 Size a portable power station from a timed load list. Check usable energy, startup surge, expansion batteries and wall, car or solar recharge limits.
Off-Grid Solar System Sizing Calculator
Wired White v2 Size an off-grid solar array, battery bank, MPPT or PWM controller and inverter from daily loads, sunless days and worst-month peak sun hours.
