Plan a complete RV solar + battery system—loads, battery bank, solar array, controller & inverter sizing, roof fit, wiring, and fusing. Built for real boondocking, not guesswork.
Pro tip: Start with a preset, then fine‑tune. The permalink updates as you edit—share with your installer or team.
DoD adjusts total battery capacity. Concurrency estimates how many AC loads run at once.
Check AC for items powered by the inverter. AC watt‑hours include inverter losses. Microwave/coffee are short use; enter fractional hours (e.g., 0.2 = 12 min).
We’ll try both orientations and use the better fit. Real roofs have obstructions—use this as a ballpark and finalize during layout.
We stock the components you’ll need, with phone, chat, email, and text support plus flexible payment options you won’t find on Amazon.
PSH condenses a day’s variable sunlight into equivalent hours at full sun (~1000 W/m²). Array size ≈ Daily Wh ÷ (PSH × PV efficiency).
Usable battery (Wh) ≈ Daily Wh × Days of Autonomy. Total bank (Wh) ≈ Usable ÷ DoD. Convert to Ah: Wh ÷ system volts.
Use MPPT for higher harvest and flexibility. We assume MPPT and a PV derate of ~0.7 by default.
A/C draws large continuous power. Even efficient units can demand 1000–1500 W, which requires a very large array and battery. A soft starter + generator is the practical path for most rigs.
Yes. Add rows, toggle AC/DC, and fine‑tune hours. The share link and local save keep your setup.
